Why wouldn't a sr20de ecu keep idle on a ga16de? Also it turns off by itself when you let go of the clutch after a couple of seconds?

uhh....my guess is that they have completely different systems

that would be my guess seing that a ga and a sr are two different engine. its like compareing a bannana to a apple.

Different MAFS, injectors, timing, sensors...........the list goes on and on. The two are completely incompatible, you might as well be trying to run a Dodge Neon with a Chevy Cavalier computer. :rolleyes:
