Throttle Position Questions

2011 Nismo#91 · 09-18-2017, 12:06 PM

TLDR version:
OBDII read out for the Throttle Positions Sensor maxes out at ~90% is this normal?

So I have been logging track data for about a year now and it always seemed to show a max TPS reading of 90%. I just though it was the cheap app I was using wasn't reading the data right. Now I have an AIM SoloDL and it's still reading the same. Here's a readout of the TPS for one lap.

I got the car tuned in 2012 with Uprev, I haven't made any power mods since then.

Any thoughts on what could be wrong or is this just normal?

Hmm, interesting. I wonder if it's a uprev thing.

My 2011 Nismo shows the same thing when I'm datalogging with Solostorm. Highest throttle position it records is 88%.
