Looking to get into EFi. I have built engines for over 20 years but never got into EFI multi port. Just a beginner, I have grasp at what sensors are needed, O2, IAC, throttle position, water temp, air temp, MAF. Its not difficult, I'm a building automation guy so this comes easy. just need to learn what sensors will work with what system....Looking to use all stock OEM chevy parts....
