Keith Posted March 23, 2018 Posted March 23, 2018 In replacing the ECU on my 89 - 4ltr - 5 speed, do the numbers off of a replacement have to match what is in the unit? If not what units will interchange?
cruiser54 Posted March 23, 2018 Posted March 23, 2018 They'll all work 87 to 90. 89 and 90 give a little more power. You can use one from an automatic also.

Keith Posted March 25, 2018 Author Posted March 25, 2018 Next dumb question, does a replacement unit have to be programmed to the vehicle VIN?
