Boost Tune Setup for Gen III

okay welcome to the guide for boost setup on June 3 cars I saw real quick come up with a disclaimer in here probably from here on out considering the the danger of messing in these things some go ahead and read this off to you real quick the information contained in this video is for educational purposes only only any modifications and tuning of engines connect undesirable consequences if done improperly before attempting any modifications please do your own research and order consult a professional calibrating procedures learned in this video are done at your own risk and any damage reliability is your own responsibility and without all we'll get in the video all right if you're here you're looking to setup your tune for setting up for booths so we're gonna have to go over a few things here so we're gonna go through the operating systems how to apply them the ve setup obviously for fueling our spark setup fuelling setup and of course some other considerations to keep in mind for boost I want to keep it as simple as possible so I'm not going to be it's not a full walkthrough is more of an overview on how to set up for boost only so let's get into it shall we absolutely if you if you have clicked on the tab yet we'll take actually gonna take a look at are you gonna notice there's a number of these in there not the operating systems of course the two most popular for boost are gonna be your t bar in your 3 bar 2 bars gonna take us up to 210 kPa and a 3 bar L take us to 315 a math can be used some some people out there still run it but most simply go if you're already in the Hance to bar or 3 bar it's it's not necessary to run the math but I'm sure somebody will argue that you can still do it because you can now the bottom you have advantages to the enhanced OS of course these are pretty nice so you have your spark tables are going to go back to using the high and low octane tables which is pretty cool just like stock and of course our main and secondary Vee if if applicable also goes back to just like normal if that if you do have a secondary VD table that'll operate just the same as it used to that's pretty much it so we'll jump right into actually applying these here in a sec alright so let's go ahead and apply a new operating system to our teen files so we have a stock file pulled up here so a stock f-body first thing we're needs click on the West tab here then you go ahead and pick the operating system we want so listen in this case we're gonna go ahead and run a two bar operating system in speed density so let's go ahead and select this applied code modification you'll notice this warning comes up here and I'll tell you exactly what to do so save file the new file name and then you close the current file open new file and then we're gonna have to use this is extremely important here use the right entire process only on the first right if you write this with the L'Arche with the just the calibration it will actually probably brick your PCM as it says right here so let's go ahead and do this so now all we have to do is save this file we've already clicked it so we close we hit save as and it's gonna come up here and we'll go to bar just and change this to two bar and leave it at body like that and I hit save then we go ahead and close the file and then we open the other file and now it should be two bar operating system nuts and now let's check on that and close this out and we go over to engine now we can go to air flow and check our ve table it's probably gonna tell us immediately and there we go we have a 2 bar applet enhanced system now as you notice everything is maxed out on the table that's just flat over here so we're gonna up obviously we're gonna have to fix that so let's go ahead and get into doing that here in a second we'll go in now actually how to set this up but that's how you apply the the operating system again one more word for the wise is when you write this you must hit write entire so if you have it set the right calibration you're gonna set select write entire just like this if you do not do this we'll break your PCM so to make sure you write it entirely and that's pretty much it I just want to make sure that that's very clear if you forget what you're doing it's very easy to do that so that's pretty much it so we'll get into how to actually stop the beat here in a sec also for north to get all this right and we're gonna have to understand what boost actually is or over talking about this actually refers to any additional air pressure above doubt and spirit pressure aka the bar or the bear row which is actually typically about 100 and 1.3 kPa around and you say 102 or 100 but it's about 14.7 PSI at sea level if you were pushing 14 psi of boost that's going to mean that we're on the 200 kPa row on the ve table meaning that you're going to need a 2 bar table so if you're under 14 psi 2 bars gonna work fine if you're over 14 psi you're gonna have to run a 3 bar so 5 psi based equals 30 4.5 kPa or about a third of one bar so keep that mind so about 5 PSI every 5 PSI we're just going to add about that much to that row feeling-wise now just as a kind of a guesstimate it'll probably run big rich but that's fine we want to make sure we're not on the lean side so in this case of that would result in it being 100 40k pierrot because it's 34.5 kPa I know that's where it will come up on the that's the road it's gonna make it to on the VE table so increasing the feeling by 30% here would be a safe number just to get started on tuning it and I'll show you how to do that here in a sec that's where we left off and we're at 518 which is a ridiculous number for vtable and it's all flat now so we can't can't leave it like this in any case we have to copy over other our other ve table from our other toon file so what we're going to do is going to go ahead and we can't use the compare file note that we can't use that and if you try you'll note that the tables are different so you can't compare them because they're different so we're gonna do is go ahead and minimize this open a second instance of the editor soon as I my computer's slow I know once it loads there we go and we go ahead and open up our tune file that we should have been working on already so ever be table already done we open up our ve table and here's our completed ve table in the naturally aspirated areas go ahead and select the old thing copy we're you go ahead and minimize the window again or or go over back to your T bar go back to the two bar and now we paste in our ve table and there we go all right so we certainly can't leave at this place the next thing we have to do is actually carry on the B table up to the end of our two bar tune that we have here so we're gonna do is go ahead and copy our 105 row now we're you guys like copy select the entire row and we're gonna copy it to the 210 row paste it in now we have something that looks like this now just for demonstration I'm gonna go ahead and show you what it looks like without the multiplication and the fuel when adding that in I'll show you what that looks like in a sec all right so now we need to add more fuel to our boost area so we're going to do is for right now select the very last row and to set up a slope and enter 1.33 this is a minimum value you can it can definitely be more depending on what type of booster running here's what it would look like on a three bar at a minimum we're gonna select the 315 row and we're gonna multiply that by one point six six six we're gonna do two thirds to the 315 row and multiply it there and it should see something like this all right now we're back to our 2 bar and we're left off on this step we have the last row multiplied by 1 point 3 3 all we're gonna do is select from 105 down to 210 and then we're going to click on interplay between vertical downs click that and now we have a decent-looking ve table is ready to be tuned for boost and it's definitely going to need tuning this is probably gonna be rich and it may even be lean depending on your case but in any case so it's gonna get a fairly a good starting point to be able to least tune it in our kit assist our selves into too much trouble alright so going into spark side of this we're kind of gets a little dangerous but um for the maximum value I've heard a few things out there but one of the ones I liked better was the 28th rule just generally accepted as a safe maximum value for spark so keep in mind that some max this however can vary like engine to engine so just like anything so this depends heavily on your compression so the high compression lower your spark should be went rule is pretty simple this is take the number 28 and subtract your boost be aside from that and I'll give you the maximum setting of a boost so in this case would go 11 psi 28 minus 11 and would be 17 degrees max that we want to use as a absolute max again I would normally take a few more degrees off than this normally go down 15 10 even 10 degrees is a good place to start did you be surprised how easily a ninja can knock under boost especially on high compression so again general rule just as a maximum if you're over that you're probably not gonna be so good that's just the point it doesn't mean you can't be so again all subjective to each engine so but it's best tuned on a dyno or at the track so of course I was it's one most dangerous settings that how we do not recommend tuning spark without a measurement tool like a dyno or the track of course and the track we're gonna use trap speed down overscan use the round numbers actually see the curve all that good stuff and of course we know pushed and spark to hard it's gonna cause detonation high heat and put you at risk for pre-ignition and these are especially more common under high loads a hundred boost so that's why everyone's gonna caution he's a down our track to tune the spark but you can get it street tuned pretty good just by doing the base settings but do not push the spark more than it needs be just one one cover that real quick before we get started all right so I just want to touch on this real quick I put this in here to demonstrate basically how the spark table works so in this case we're gonna look at the top left we see our idle area in top left and the bottom right where wide-open throttle area and the top of the table we have our D cell area and in the bottom left and bought top right we have our premature I'm affable cells now it's kind of very engine engine this can be different on each engine but doesn't mean you can't necessarily get there but in most cases you can't it's pretty hard on most engines and it all depends on how fast your engines pulls up that kind of thing this is just the general track and how the engines going to spool through a wide open throttle full throttle that's gonna shoot down in air mass and it's of course gonna go up in rpm so it's pretty much gonna go straight down the table like this you're wide open table wide open throttle area on the bottom right it's gonna shoot on up and then as you let go with the throttle it's gonna come back up and as the air mass drops it's going to come back down rpm band and just like so and end up in this elliptical out so I just want to put this in there to kind of demonstrate so you can wrap your head around how the spark table works and kind of how to how you how we're gonna go ahead and set it up from here on out alright so moving into spark table set up for your high octane tables is going to be determining the wide-open throttle areas as we already kind of pointed out on the other example of course that's gonna be our most important area of court and we're gonna go ahead and check out the wide-open Charl blues regions uh using the twenty eight rules the max value so you don't want to go above this try not to go above it in most cases you should be okay reduce spark on the ramp in areas as well because you can also find you'll find a lot of knock happening there's mid-range and if that's the case is pull the spark out there but and in most of those cases it's not usually a life engine life-ending thing if you get some knock and less is severe but most cases you might experience a little bit knock through the transitions so definitely pull the spark there verify today's the spark doing it or used some high-octane fuel to determine if it's false or not because a lot of times it can be but at the end of the day the wide open throttle area is where it's really gonna matter so we get knock up here at wide open throttle 100 high stress high boost setting scenario that's where it's gonna really do some damage if it does occur so that's why we pull it out of there first and kind of work the ramp in areas later we're gonna reduce spark in the ve area as well max ve if if you want to identify that it's just the lump on your VE table if you have one of this gonna depend on your type of blower really only time this gonna matter the most part it's a positive displacement blower because of the the weight maxvill is gonna occur whereas on a century blowers gonna actually be a long bell curve or slope so that that's kind of kind of something to keep in mind on the type of how the hairs can be in turn engine and then of course the entering a blending table that's definitely on some I like to do I like to blend everything make it nice and pretty and smooth I'm just the way I do it it's like all my tables look nice and smooth when I'm done that's about it so we'll move into how to set that up here in a sec and so here I get the high octane table pulled up from the spark tables so we're actually gonna do is pull some spark out because a bone stock Oh 411 tuned so it's gonna look a little different to pay all that you're working with but you can see right here in the bottom right corner we have our wide-open throttle area and now note that on a bone stock engine it's highly unlikely that it's actually going to get to one point two grams of cylinder air mass so if you looking at these numbered thing they're pretty low it's because they are so it is highly likely that going up through this you're actually gonna be more in the center of the table like an perhaps around this area here so with boost though and bigger injectors you're definitely gonna end up on this bottom row very quickly so let's go ahead and pull some spark out we're gonna do it on the wide-open throttle area so we're gonna start about like let's care about here in the middle of the table and a little bit lower on the bottom right down right about here we're just going to carry it on over here we're gonna set this value down to we're gonna go ahead and use 15 15 degrees should be a pretty pretty safe number for uh for most blowers to paint on your psi level now that would be assuming on you know let's say 10 10 psi that'd be a good spot decent again can vary depends on depends on the engine depends on the car so next we're gonna do is look at the ramping areas as talking about those so you get the ramp in here but of course you're not gonna start here you're gonna start up in the top-left corner so we're gonna have this actually right here as the ramp in is from here to here this area is what we want to look at and if this is a centrifugal blower we don't have to do a lot other than to blend this in depending on where the boost hits but the you can see the numbers aren't actually that high this actually wouldn't be a bad way to start so I'd go ahead and uh let's go ahead and blend these together like this we're just gonna blend them so we'll smooth selection like so and now we'll go ahead and smooth this in to the idle area a little bit smoother and just to smooth the whole table out a little bit which is what I like to do and now we have something like that and that'd be a good starting point for more boost because now we have a good wide-open throttle which that's where it's gonna matter if this is a PD blower of course we're gonna have to reduce it everywhere pretty much up here for a positive displacement again noting that the boost is always going to be existent so it's going to stay consistent throughout so the ramp in area isn't gonna be that big a deal so so this this is what it's something it look like on a centrifugal blower or turbo something like that you could run something like this this is just taking a stock just a starting point again starting points so all I did was take a stock tune file and modify the bottom area just a little bit to give me some where I could start about 15 degrees a spark in and that should keep me out of trouble for the most part 10 degrees is a lot of gotta start around tan 15 is okay too but don't and this all depends on your boost level if you're if you're above 10 psi this might this might actually be too high so keep that in mind too so anyway that should about cover how to set up the spark table I'll cover one other example of ALS one two however we try that real quick we'll open up an ls1 tune and we'll take a look and do that one real quick same way well we'll just uh we'll just go ahead and open that up see bone stock ls1 alright so we'll go to the spark table again we'll go to high octane and now we'll take a look in this significantly different and the other one isn't it interesting and it's a lot higher in the spark values to those as you see on the bottom it's twenty eight so we're gonna go ahead and just take this whole wide-open throttle area again we're just going to set that sucker down onto this Alisa we'll say 15 again we'll do that we'll do something like that fifteen degrees over here on the ramp in you have to max PE but we're gonna assume this is a PD blower so we're gonna go ahead and just pull everything out and ramp it in so as a PD blower would be so we'll just go make and make this one about twelve in the center rate region you don't want it too high and then above it same thing we'll just leave it twelve or so there and we're going to make sure yeah all that looks good we'll take this corner and we're just gonna go ahead and blend it all down like so and takes this area here one that - I got a spike I don't like here and go ahead and hand smooth this out I don't like that yeah I'm not liking that spike there I'll make this a hole does interpolate the selection I think so okay it's looking good that's not too bad something real quick changes like so and then I might have to change these up here later but that's gonna depend on your blower and how fast this pulls up but really at 1200 rpm I'm looking at it getting to 15 degrees working its way down like so should be okay and even through the max abilities it should be all right that might be a pretty conservative a number but uh that's fine when we were talking like a positive displacement here so that's something like that and then on the top again we'll go ahead and just select a little table smooth it in a little bit like so so it can ramp back up something like that that looks good nice and smooth nothing no surprises nothing crazy and that's a bone stock illis one so you see it turned into something similar to the other table just the same again this all can be adjusted later this is just a starting point something I can plug in and I kind of get a start on tuning this spark later on and again best way to do that so i'm dinah north track but that should about cover the high octane table cover how to do the low octane table here insect alright so under the improved operating system the low octane table is functional because the high octane table becomes once again this becomes the primary for the low octane table in this case on the new UPS operating system on this Ibaka it's a backup table and it's gonna be based on knock learn factors so the more the the knock line factor goes up the more the PCM is going to bias towards the the low octane table so that means that if I set my table 10 degrees less on my wide-open throttle area the most the PCM could reduce the the spark based on knock learn is down to let's say it was fifteen on them higher to be down to five degrees on the lower came so then that makes sense something like that and pull about ten degrees off the white I'm throttle and usually about 15 degrees out the bottom left and usually that's about about good we're gonna blend everything together and and again it's just a backup table in case you're getting significant amounts of NOx so this table actually isn't don't worry about the numbers on it so much worry about if you have knock or not that's actually but it'd be more concerned with if that's that's what you're thinking is this table actually doesn't used unless that's the case so keep that in mind so we're just gonna set this table up to be safe so that gives it plenty of room to move towards a lower number if needed alright so we already got the hierarchy table kind of worked out somewhere we can get started on tuning this so what we're gonna do is set up our low octane table real quick and this is just as a backup safety so the whole point of the low octane table is to work based on knock learn factor so knock learning is a it's basically when the knock can is a persistent for some time it's going to start to revert to the low octane stable soda pan what the knocking learn factor becomes the farther it's gonna slide over to low octane tables so that's the whole point of doing this part is we're going to pace the numbers from the high act and table at the wrong button and we're gonna copy them straight over to low octane table like we did before and speed density chaining to tune all that but now that we have the new operating system this table will function again so what we're gonna do in the high octane or the for the low octane table here is gonna reduce the wide open throttle area just like we did before we're gonna pull I'm gonna go ahead and take out 10 degrees here and and then minus 10 or does it add that in I'll drop that out like so then over here on the bottom left we're gonna do the same thing we're gonna go ahead and pull out roughly about 10 to 15 degrees there and in order to pull thought out two will blend all of that together will interpolate actually sure - let me go ahead and reverse that change you're gonna add negative 15 to this corner so we're gonna add it instead of there we go that's better all right so now yeah now we go ahead and blend them together and to blend until the humps got something like that and we can blend this area too in as well so something like that we don't wanna mess Vidal too much this shouldn't knock in this region anyway but if it does knock blend again you know like nice smooth tables blend looking good and that should do it so the numbers on the top can be the same up here on the D cell that's fine however on the in this region down here we want the number very low because the PCM starts to get the knock learn we do want it to be able to pull the spark out so it's gonna potentially if the knock learning factor is maxed out it could potentially be down to five degrees so that's as low as it can go - and again and knock Corrections but and then of course the bottom left to be high load or high fill and a little load that's also a bad thing so we want to make sure sparks actually negatives over here which is pretty typical so that's about it um so we that that's how we're gonna set up a pretty safe it's just a safe table safe logging tables of backup this tables not used normally unless the knock learnin is on you know it's learning and getting lots of knock and yeah this table is going to be used but that's just something this is a again subjective like you do this a little different a lot of different ways but this will basically make sure that you're not getting too much spark if you are getting lots of knocks so it'll I mean I know the values are massively low there mom keep in mind that this goes off of the knock learn factor if you have knock in the first place you got bigger problems we compare the tables we see there are only 11 degrees here and if you're knocking it needs to be less than that clearly so that's that's the idea so that's all that's again based on an agenda engine just a an idea of what to do and why you're going to do that low octane table is definitely useful with knock learning so as we see the enable so learning adaptive learning here you see the enable should all be on from the stock setup service so again a stock tune so you see as it's enabled here these are the values that enable it and pretty much so as we get knock it's gonna start learning and you lot of nuts is referred to as not learning factor in the scanner but oh that's it for that alright so here's a tune file I borrowed from the repository you now know this is quite a few things on there you may or may not find what you're looking for exactly as far as a lot of things go on the repository but basically this one on I'm going to show you because I like the way this one looks this a PSI turbo 76 millimeter turbo on a 40 truck so you see here you see this spark table like so so it's exactly what we're talking about the kind of the way to reduce the area so we have down to 16 not a lot of work on the D cell area that's been reduced a little again if needed you pull it out up here but you see how how it just steps up and also on this one I like to point out another good idea as as you see as the air mass increases the spark steps down slightly and goes all the way to the bottom so the lowest number be in the bottom right corner and it works its way up as it goes back up so I kind of like that idea it's a little Ripley to me but still looks good it's not little table here and uh it's another example in this runnin 76-millimeter a PSI so you can see the idea this is run about 16 degrees of spark advance and of course as you see and the bottom left it's down negative 9 and then on I see your low octane table is down negative 16 etc see it's kind of same or it looked exactly the same as ours it's a little bit higher than I'd like to see it in this region but but again good example of a decent food table that misses a running truck so it's a real tune no complaints from the from the owner apparently so yeah and just like so I just wanted to point that one out so um you guys can see uh kind of what I'm talking about so alright so there's a lot of other examples out there but not all of them are the best to look at that uh there's tons of examples whatever works for you is what is what works for you at the end of data and whatever gets you down the track passes that's that's the one you go away so I'm not gonna beat that up too much more I think that about covers how to set up the spark tables for boosting ok so as we know the ve table is our primary a feeling table essentially I know that it's a it's actually really the air mass calculation however increasing the air mass calculation will increase the fueling because that's how it's gonna work out in the math however in order for the enrichment target to be correct and boost because we're gonna be talking about things that are over the the actual values we want it must be built into the table like as far as the target to get it to target anything above 100 kPa we actually have to build this into the power enrichment or the booster nourishment now there's two primary methods of doing this and that's of course that's power in Richmond only as a target I use an RPM based this is RPM based with boost enrich is a backup because it's gonna the PCM will use whichever table is richer so if you use that power in Richmond is more reliable as nuts well one I'm going to show here going based on rpm and then we got our power enrichment as a ramp into boost boost enrichment and b b:e as the target i'm not that of course means that boost nourishment will become richer as at some point usually into the busted' about 110 kPa we start setting it richer than the PE and then it'll use the boost enrichment from their own up now keeping in mind that some PCMs are a little slow to activate boost enrichment and this is why it's usually better to go with the power enrichment setup and just go off rpm and it's actually pretty pretty reliable that it's gonna work whereas an boost of enrichment of course whether you set it as a backup make it rich as well target the 11-5 if that's only if you hit boost or hit those numbers before you hit the RPM to trigger the power and Richmond if that makes sense so that's what boost enriches support but other than that so we're going to talk about at least how to do the power in Richmond just go over boost enrich and you guys set this up as desired on your own setup and whatever works for you is what works on but a lot of people do it it's just one of these two ways pretty much that's the two primary methods alright so the method I'm gonna show in this video is going to be the power enrichment version so instead of using biznitch mint we're only gonna use punishment and we're gonna set this enrichment basically to act as a backup table so this is probably the most proper way to set it up I know I'm probably gonna catch and flak for that in the comments but I'm gonna go with some big decision and say that partners from the way to do is we're personally I prefer because it's RPM driven are based very easy to know when it needs to be on and it's pretty easy to set it up that way and be can still be used as just as a backup table just in case you end up in to boost some other point during the RPM band that you weren't intending but you set it a little bit lower than the target for the PE ratio in that way if you do get into that point it'll just kick in and act as a backup safety net but on it and we'll get into how to how to set it up here in a sec alright so I'm going to show you how to set up the power on your screen now the numbers we're gonna use gonna be based on stoichea still kyo stoichiometry stoichiometric number which is a forty one six right here stoic a far so 14 one six three DS what we're basing this on i'm on over the pound rich here we go first thing i'm gonna do is set the math navel up to 70 next time I go over to pound Richmond the EQ ratio and make sure that's correct now this is gonna be based on my blower if I have a PD blower I pretty much set this right across the board that would be positive displacement it would look like this so just be 1.27 and just call it a day like that and that's fine or if I have a turbo or a pro charger or another centrifugal blower I would identify where I'm getting into boost and we're actually do need to be 11-5 in that case I'd probably let's say let's say it hits 11 5 at 5 psi 4,000 so at 4,000 I'm gonna say about 5 PS I'm gonna want to be a roughly about 11:1 you're living by so before that I don't need to be so I'm gonna go down down to the bottom here I said select up to about let's just do it like this let's go up to 36 and go 1.17 like equals make something like that and we'll blend it in like so boom there we go Nana that will work so there's there's our centripetal version so if we are in power any area we don't need to be at 11 by 11 5 but once we do hit boost and or say around the 4,000 rpm mark if that's the case for your blower then yeah we need to be a little I so that's what we're gonna look at so something like that will work just fine now for our backup just in case we don't get in at power nourishment which is going to be dictated by this but this this throttle pedal right here it's gonna this table right here is going to dictate that so if I'm at 4,000 and it takes 54% throttle it might not actually take that much solace let's say let's go ahead and say it takes 40% to hit boost so we'll set it to 40 and we want to get into it sooner or later it's a little triplet typically that in kind of smooth this out and make sure that that this matches where we need to be the boost and where and where we need to be with our fueling keeping an eye on that that's going to be from the scanner and may have to come back and adjust this now in the meantime we can use the boost enrichment table as a backup in case we don't hit the if we aren't getting the commanded that we need into boost which is pretty easy to set up because we're just gonna select the whole table and we're gonna set that at one point to one point two six across the board just so slightly leaner than the other table um not a big deal so that way it sticks to the power and Richmond so it doesn't trigger this table all the time so little point mean is uh I wanted to use the pound Richmond and use this as a backup if it doesn't get into power enrichment because of this table then it's going to use this table based on map and that's why it's a backup table so it does there are times that can get into boost and not actually trigger the power in Richmond and that's why this table exists so that's that's that's a better way to do this it's a better way to set it up it's a safer way so that way we have two tables basically covering down make sure we get it ready for us at the end the day but that's pretty much it so I hope that hope that was a clear enough the delay we can only does zero obviously Richmond trait we leave that alone as well some guys they increase this I have never really seen need for it but other than that yeah that's how that's pretty much all we do to set up for boost feeling then from here we teen RV table and our our targets should be appropriate for our boost levels and and maps that's pretty much it alright so other considerations this may not be all of them by the way but I go ahead and wrap this up with using correct map sense here for the calibration for what you're using so if you need a two bar or three bar make sure you using that and then apply the right offsets and verify that's working with another gauge next would be a use proper heat range of spark plugs this is something else people may forget to do his general rules go go down one heat range for about every 100 horsepower above the stock plug so that makes sense so obviously run them and confirm them check him for overheating that kind of thing and finally move the IAT sensor to the intake manifold it's a good idea because it adds to heat and so that's where it's gonna build up a little bit more so it's another good consideration to do that as well but other than that there's some pretty much covers everything for the most part they at least get started on tune in the boost and hopefully hopefully it works out for you hope you guys enjoyed the video and I'll see out there
