TPS won't go below 14%, or above 88%

[AustinL911A]

I'm still completely new to this game, so go easy on me.

This was my first log ever, in a friends 2005 vette. I noticed while logging that the TPS % won't drop below roughly 14%, nor will it go above 88%. What's this all about?

I tried to find a table in the tuning software to adjust how far the throttle blade would open, but didn't have any luck finding such a table. (Again, I'm completely new to this)

If you need the log file, I could email it to ya. Just let me know.

Thanks guys, and love the software so far. :master:

Nevermind. After actually reading for 2 minutes, I think I found my answer in another thread: :bash:


Did it ever log 100%. Does the blade open 100% visually if you look at it while the pedal is held down. I have read that SAE.TP won't go past 88% on these vehicles as it is referring to a % of 5V rather than physical TP. GM.ETCTP is the PID to log.


I'm gonna give this a try. Will report back with details. :notacrook:

It still won't drop to 0 though as the throttle blade is regulating the idle airflow on ETC vehicles(i.e. there is no IAC motor). But you should see much lower than 14% at idle.
