65mm Throttle Body Fun
I swapped over to a MAP 65mm throttle body today, go to start the car up and it throws a P0122 (TPS low circuit) code. I think nothing of it, I confirmed the TPS sensor is working properly through evoscan, also dialed it in using evoscan. Once again I cannot get the car to idle right on a 65mm throttle body (this is my second one, first one was a curt brown tb). I have the BISS screw turned almost all the way in and I cant get it to idle below 1400 rpm. Also, the car wont go into decel afr on throttle lift, it just hovers around 12.5-12.8 afr. This is literally the exact same thing that happen with the Curt Brown throttle body, I got pissed, took it off, and sold it. When I actuate SAS mode in evoscan rpm comes down to target idle, but as soon as I leave it goes right back up. Any ideas?

Yes, apparently all the 65mm throttle bodies I used were fine, the tps I was using reading 5.5% higher than a normally functioning sensor. I posted my findings to hopefully help someone that has this issue in the future. Nothing worse than troubleshooting a problem online looking for answers and stumble upon your exact issue and nobody ever responds back including the OP.
