Let me try to clear up some of the confusion, I just picked up a ITR throttle body and im about to replace my GSR throttle body. I was told that the voltage settings at idle should be roughly .45 and 4.5 at WOT(wide open throttle), can anyone confirm this ?

Should i use the same voltage settings from the GSR TB on my new ITR TB ?

how to check throttle body voltage with a VAFC:

1. go to "etc."
2. go to "sensor chk."
3. read the 2nd line from the top

 

With my car off, 0% throttle reads .48V and 100% throttle reads 4.58V. Hope that helps. By the way, you can make the vafc relearn the throttle positions. let it sit at 0% for 10 sec. and then full throttle for 10 more sec. I read it in the manual somewhere.

 

the voltage should be the same for GSR and ITR, otherwise the TPS sensor wouldn't be plug and play, and your car would go insane.

He's right, its in the manual and its 10 secs both ways. You can also check it by putting a volt/ohm meter on it and read the parameters from there. Just take a reading from the sensor with no pressure to the thottle and then 100%pressure. My throttle readings are .45v closed, 4.75 wot. Hope this helps.
