Post by LegacyPGT »

I did a auto to 5 speed conversion on my 93 turbo, is the ecu different from the auto to the manual? cause i am lacking some power and i was woundering if this is the cause.

yeah I believe they are......but that shouldn't matter, as long as you've dealt with the MT/AT identifier pin going to the ECU.

The turbo AT and MT ECUs are the same. Like Josh said, you just need to tell the ECU what kind of transmission you have.

In your case, you just need to cut the wire going to ECU pin B48.20:

I don't know if this is the reason you're lacking power, but it will at least be affecting your idle quality according to Dave's experience.
