I have an 89 GT it only runs on the old school 302 firing order, when I wire it correctly w/351 firing order it barely will run. Does that mean I have a non HO computer? There is a lot of numbers on the computer,which number do I read to find out which one I have?? Is there a site to go check these numbers? Thanks!!

well i would think it wouldnt be the ecu , it has to do with the wiring as far as the the way theinjectors fire.
Because on old school cars they use out al9 ecus to wire the up for injection . Alls they do is change the wiring around.
Do you have an ho cam? That would make a big differnce . If its a non ho cam change injector firing order around to non ho.
