Okay, I dont own a mustang, but I do have a 1989 5.0 non mass air flow engine I am swapping into my 1973 classic Bronco. My question is this, where can I ship my ECM to have it reburnt to eliminate the air pump and egr valve? Any help is appreciated.
It may not throw a light but if you just unplug it all there will be a code. Alot of the 5.0's didn't throw codes. I ran my 90 Gt parts car with no h-pipe, no o2's hooked up and it STILL didn't throw one!:smash:
EGR only works at part throttle/idle anyways, at WOT it is shut off.
