Hi all, I'm pretty sure my setup needs a tuning chip, just wanted to pop in here and get your guys' opinions.
1989 325iA, OBD1 converted S52, pink top injectors, M50 manifold, stock red label DME, 3.5" intake, 3.5" MAF (540 or 740, don't remember).
As I'm writing this, I'm remembering I've got an OBD2 throttle body on the car. I don't know if that could be the cause of the issues I'm seeing. I've got a rusty M50 TB, can I just swap the sensors between the different throttle bodies?
With the MAF plugged in, car doesn't start.
Plugging the MAF in once started, the car will idle but not rev.
With the MAF unplugged, the car idles, but has considerable rev hang in neutral, and stutters a lot under partial throttle when driving around. WOT is okay.
