Wasn't sure which board to post this one (so i chose the OEM board).
Here's the situation. I have an 89 XJ that *used* to have an automatic transmission. As it has been documented over time ... i have since swapped in a AX-15 trans.
At the time, I simply removed the TCU and made some corrections/terminations in the wiring harness.
Fast forward 6+ years and my computer has finally passed on. I'm trying to determine if i want another ECU for an auto trans. Or would i want to purchase one for a manual trans.
I have contacted the rebuilder (A-1 Cardone) regarding the plug/pin configuration. They are identical. I have been able to determine that the manual ECU has a slightly faster timing advance. Past that, I'm unable to determine any additional differences between the computers in terms of capability or compatibility.
The biggest difference, i've found so far, is the price. The manual ECU is 87. The auto ECU is 101. Most folks locally (and the tech at Cardone) suggested to just get another auto ECU .. since it has worked for 6+ years without any codes.
Can someone offer insight regarding with ECU to get ... or direct me to something that can offer concrete info on the differences between the two?
I will be cross posting this to a few other boards as i'd like to have some clue as to what to do by the end of the night. I will be ordering the ECU in the morning (to get it for the afternoon).
Thanks much folks !
