COBB Tuning - COBB University Episode #1 - Introduction

[Music] welcome to cob view this video series will take you from start to finish to teach you the basics of various automotive systems and how modification and tuning work hand-in-hand to help you achieve your car goals in a sea of internet experts we aim to be a sensible unbiased source of accurate information regarding vehicle modification I'm Emmy I'm just one small part of the team here at cops unity if you're watching this you most likely own a vehicle we support you're familiar with what we do already for those that are unfamiliar cobb tuning makes engine management solutions and performance parts predominantly for small displacement turbocharged engines that's what we'll be talking about in this series while these videos are aimed more towards folks who are new at modifying their cards we hope that whatever your skill set you walk away from this with a better overall understanding of how your car really works no matter what it is that you're doing you need a good foundation to build off of so today we'll begin with a basic overview of how your car works from intake to tailpipe we'll cover specific systems on their own in future videos throughout this series we'll be referring to this real-world mock-up we can show you the actual components and how they intermingle with other systems for the sake of visual explanation we've stripped the engine of systems and components that are not discussed in this series that way we can easily see what we're talking about so when you look at your engine you will see way more parts than what is here one more note this is a subaru ej 25 motor and we're using components from a 2015 Subaru STi to keep in mind that your vehicle may be designed slightly different we'll be covering some of those differences in later videos with that being said let's get to it an internal combustion engine needs four things to run fuel air spark and compression once you have those here's how everything else comes together first air enters into the air intake and passes through a filter which is then metered by a mass airflow sensor also referred to as a mass sensor from there the air enters the turbo inlet hose and passes through the compressor side of the turbocharger the air then goes through what's referred to as the hot pipe and enters the intercooler as the air moves through the internal passages of the core it's temperature decreases because the heat transfers from the air to the metal core cooler air from outside passes through external fins on the core in an effort to reduce the temperature of the core itself allowing it to continue to cool the air inside once that happens the cooled air makes its way up through the cold pipe entering the throttle body the throttle body houses a butterfly valve that controls how much air passes into the intake manifold which then directs air into each individual cylinder just before the air enters the cylinder we have the mixing of air and fuel which is provided by our fuel injectors the air fuel mixture then enters the cylinder through the intake valve as it opens during the Pistons downward intake stroke the intake valve closes and the piston then compresses the mixture as it travels upward on its compression stroke just before the piston reaches the top it is ignited by the spark plug the pressure from the combustion pushes the piston back down on the combustion stroke giving your car its power lastly the exhaust valve opens as the piston travels back up one last time on its exhaust stroke evacuating our exhaust gases at that point the exhaust gases make their way from the exhaust manifold into the turbine side of the turbocharger spinning the turbine to provide necessary energy to build Vuh once our exhaust gases have finished their jobs they'll make their way through the down pipe and pass through a catalytic converter to reduce emission from there the exhaust gases pass through the rest of the exhaust system which include a resonator and a muffler to help dampen the sound and then finally they make their way out the tailpipes everything we just talked about happens thousands of times a minute all while you're on your way to the grocery store or the track it's a well-organized chaos at its finest now that you have a basic understanding of what's going on all the way from intake to tailpipes we can break everything down into their individual components starting with the next video which will focus on the first step in the upgrade path ECU tuning your car's ECU or engine control unit manages a lot of the systems we touched on in this video so before you start adding any parts it's important for you to understand how the ECU and ECU tuning work to help you realize the full power potential of your car while working on your car you'll need a wide variety of tools for the systems will touch on throughout this series you'll generally need tools like ratchets and sockets Allen wrenches or hex socket wrenches screwdrivers pip and while not needed but are extremely handy a small mirror and telescoping magnet to help retrieve screws and bolts that fall through the cracks various pliers torque wrenches and silicone spray while recovering specific tools needed in each episode one last note for those of you that are eager to learn more at the bottom of each video on our website you'll find the extra credit section that has links to additional information about the topic discussed in that video that's going to do it for this episode of Cobb you thanks for joining us and be sure to subscribe to our
