How to Read, Erase, & Write EProm EEProm Chips Electronic Fuel injection DIY Tuning GQ-4X Programmer

this video I show you how to use the GQ Forex programmer to read your original prom this is a this is out of a throttle body injection car 24-pin we're going to read the bin off of it so 27:32 prom and also I'm going to show you how to read write and erase the flash chips this is a eighty twenty nine C 256 okay so to get started we're going to plug in our programmers or USB I come over here we're going to launch the software you're going to want to make sure that there's no problem in the programmer when you launch a software so you're going to have to select what prom you want to read so I'm going to come over here I'm going to go to device and I'm going to select EEPROM stay on all generic going to look on the next row for 27:32 and I'm going to go with the 2730 to be that's the lower voltage I'm not sure exactly what voltage is chipper on then I select that to put our EEPROM in the programmer lock it down come over here and we're going to read it so it finishes the read very quick is like 0.3 seconds so then if you want to view the code that's on the chip this is a message largest two tabs there's code so you can click that this is the code that's on that chip you can see it takes up 4 kilobits so it doesn't take up a huge amount of space on the EEPROM and the entire you promise filled with code top to bottom so that's how you read you prom and then if you want to you can save that file copy or save and it's going to be a binary file you can name it and store it anywhere you'd like to store that I'm going to show you how to read erase and read and write to a flash chip this is a eighty twenty nine C 256 and put it in the programmer hook it down I come over here and we have to select new device because it's a different type of chip than last one it's a flash EEPROM it's a at now eighty twenty nine see ah 2:56 so right here select that one I come up here we're going to do a first what we're going to do is do a blank check which is the button right here the B and it's going to say like check failed because I know there was a program on there so I'm going to do is you race that chip now first let's read it let's see what's on there we're here to read so just read it I'm going to look at the code and you can see it's filled with FS so all these little FS in there that's just a buffer when you program these you have to fill the entire chip top to bottom so let's scroll down a bit go on to large chip we only we're only using 4k of data on this chip so here we go starting to get into the programming now that starts at zero zero zero zero seven zero zero so this is the program that's a 4k of data right there that's on the EEPROM okay so next we're going to erase it which is very simple just at erased button get that in point three six seconds blink of an eye I'll do it again Rhys that will do a blank check again and yes chip is blank so the next up we're going to program this chip we're going to do is we're going to open a file and then over here open file I'm going to go to my desk desktop and here I have 3 or 5 GB I bin files so we're going to put on there is a fdy right here let's select that now right here you need to put in the offset so what the offset does is it fills the entire chip with those FS except for your data goes so you need to do is put in just put in zero zero seven zero zero zero that tells it where to start burning your information so be all FS up until that point that's called the offset click OK go up here and hit right so we're going to write file now and I checked these boxes over here so when it writes it also verifies that the information is good so we got it hold on and I come over here I'm going to read chip now take a look at the code got a lot of F's in there and the code start at zero zero zero four zero zero zero zero zero seven zero zero zero and that's right where it starts all right so that's a enough information you should get you start on how to read and write to the flash chips and how to read your original bin file okay guys here's a little more information on offsets you need to put in an offset because you need to fill a chip totally with information and you're using a 4k bin which is going to it's not going to fill the chip all the way so you need to put in offset offset is basically it tells where to write the actual bin data on the chip and here's if you go to motes that net he has information on how on different offsets and you can print this out so depending on what chip you're using here's some different offsets you can use
