mechman, when you get a chance, can you please read your TPS value on SG2 for zero throttle?

My 2000 Corolla 4spd shows TPS value of 9 on SG2. I have a theory about adjusting my TPS to lower this value, hoping that the ECU/TCU will upshift earlier at higher throttle openings, or that it will shift at the min speed required despite having a higher throttle opening.

I had a '90 Camry that I left the TPS disconnected and the ECU shifted the car extremely early.

Edit: It appears my Corolla has no adjustment for the TPS
