Idle Tables and Tps voltage problem's
 
3 Attachment(s)
My 1998 camaro is having a problem with the Tps and idle table's.
Car is a 346 H/C/I running on E85 with fast 102

I get the Tps setup at .43 volts closed on showing 0% on the tps at idle.

Start car cold or warm and as it idle's it goe's from 1000rpm's to 2000rpm's and still showing .43 volts and 0% for tps

I am new to tuning world and slowly learning all the in's and out of the info i am seeing. is my car in the idle tables or falling out due to high tps voltage...or voltage problem

log's uploading now

You need to bring your IAC counts down to 45-70 when engine warm/hot at idle by using the T15 screw on the TB order to open up the throttle blade a bit.
After your IAC counts are already in the 45-70 range (again when engine warm/hot) make a TSP reset. Next step would be to make an idle_airflow log.


Hope this helps ;)
