As some of you may know, I’m in the process of converting my s14 from auto to manual. heres my questions:

I found someone selling a ecu from a 96’ w/ abs and OBDII. my car is a 97’ w/ abs and is also OBDII(obviously). Will the 96’ ecu be compatiable with my car???

Yeah I would keep the auto ECU. You shouldn’t need to buy a new one.

My Auto ECU ran a program while stopping, it would increase the RPM above 1500 then drop to idle. Very annoying, but I don’t know if this is true for S14’s.
