If there is codes stored in the ECU the timing to return to the normal values. I would check it with timing light and make sure its right. It is realy easy to adjust... Just loosen the CPS and rotate untill it is at 10 deg at idle with the diagnostic port shorted.
If your check engine light is off, or if you don't have any codes stored, then you will be back to normal. If you have codes, unplug one of the terminals on your battery for about 15 seconds. That will clear it. You probably already knew that.
My 91 Supra had issues moving from a stop, I would have to put it in Low to get it started then put it in drive after getting up to 2nd gear speed to for it to move without it acting like it would slip from a take off in Drive. I drove it to work (car dealership) and it stopped wanting to move...
I just did a swap and I and trying to fine the best way to keep the original gauge cluster and I’m trying to figure out the best way to convert the speed cable on the Supra to electric sensor on the transmission I’m using a t5 Borge Warner any advice out there
