You can wire just about any factory ECU you want to this engine. The later ones are even flashable. You can get a 3G Eclipse ECU and harness for a few bucks and wire it in if you want to run OBD2 with DIS and be able to flash it very easily. Its a billion times easier than a standalone for some DD action. I don't know why people spend so much time trying to figure other stuff out when its so easy to plug something factory in lol.
