auto log, tps when shifting

[blktalon3]

When I'm logging WOT, the car shifts and the tps postion drops about 10%for a sec then jumps back up to 100%, is this normal?

Is your car stock? If it has a stock auto ecu it will pull timing between shifts. It might make the tps think it's supposed to adjust accordingly to the timing change. Just my first thought. Hope this helps

No, it should't change unless you release the pedal, if you keep your pedal on place and the tps still changing, then your tps is not good, Timing has nothing to do with tps,,,, Tps is based on the throttle (how open or how close it is).

Some times the transimission change gears while going on constant speed, This is a common problem on our dsm and is caused because of the tps playing up and down, when the transmission sees the tps to go down, it thinks you released the throttle pedal and will switch gears down.

Just change the tps with a good working one.
