I have looked all over on a few sites and read through many posts here. I would really appreciate a well informed answer on if I need to swap ECU's. I have a 1985 pickup and it currently is (or was) a 2wd with an with an auto transmission and I am swapping it to 4wd and a stick. I have heard that it would not matter but then the few other posts I read said that it ran rough and was flat at low speeds and hard accelerations. Should I be looking for a 4wd stick ECU? I know it should not matter on the trans as it will not affect the shifting in anyway but I could see a variable in the spray timing between an auto power band and a stick. I appreciate any help with this as I am a little confused. Second on this is how would I know if the ECU is good when purchasing? I fear there is no real way to know until I hook it up.

Anyone have info on this??

The part numbers are the same for automatic vs manual for the same engine type. The 22R, 22REC, and 22RTEC have different part numbers.
