Hi,
I have an issue where my pedal position sensor takes too long to react from 100% to 0% when lifting off. This causes my car to over-rev when shifting gears due to throttle body not closing fast enough thereby delaying 'TPSClosed' state for overrun to kick in.
I must stress the issue here isn't the TPS but the PPS. I have attached a log, take a look at the last 6 ppsA and ppsB spikes. It takes 120+ miliseconds to go from 100% to zero which is too long. On a stock mechanical setup it was 40ms.
The car is a Supra mk4 running DBW on a Syvecs S7 Plus.
Any help or guidance would be much appreciated.

Re: DBW PPS too slow to respond
Can you also log the AN0X channels the PPSA/B are attached to and/or ppsAV/ppsBV?
What is the pedal from?
