Rhys Chalmers Posted May 4, 2023 Posted May 4, 2023 I have a 1987 4.0 manual. Looking for an ecu from a later model 89, or 90
jveleven Posted May 4, 2023 Posted May 4, 2023 I have one from an 89 that I grabbed out of a junkyard comanche as an extra. I know it’s out of a 1989 with a 4.0. But I can’t remember if it was a manual or an Auto. But I might have also read that that doesn’t matter? Anyway. It’s also untested since I don’t have the capability to test it without ripping my current working fine ECU out of my truck. Which is also a 1989 4.0 manual. Not sure I really want to do that. But I could let you have it you think it would work for you for $75 shipped?
Rhys Chalmers Posted May 5, 2023 Author Posted May 5, 2023 Yea that should work great! It ends in 429 which I believe it means it's for a manual. If it was auto it wouldn't matter since I control the shifting anyways.
