I noticed that EvoScan indicates a TPS value of about 12-13% at idle and that a value of 100% happens about 1/4-1/2" before the gas pedal bottoms out on the floor. Is everyone else getting similar values?

 

Nah mine is 14.11 at idle and when it hits the floor that is 100 for me..

 

Mine is the same... Generally its a tps sensor adjustment, but if its not giving you a problem you don't have to fix it..


Basically the "Correct" settings for the TPS sensor is about .6v at idle (closed throttle) and 5v at WOT... this would explain the 13%/14% value.. I always found it odd that my TPS would be 5v/100% at 3/4 throttle or so.. But I never adjusted or corrected it since I had no problem with it. Some sensors had slightly different range so when they were adjusted for .6v at idle, it would be at 5v slightly before WOT..

Go figure.. as long as its around 13% or so at idle then don't worry too much..

 

^same here.
