I changed my TPS today, and noticed something "extra". The TPS should only be connected to the other wire (not sure what it is called), nothing inbetween, am I right? Inbetween the TPS and that "other" wire was yet another connection, with a small rectangular black box in the middle. On the box was a red light on the left, and a green light on the right. What is this? Nobody can tell me, and the car still runs as good as it did now that I removed it. Any ideas on what it could be?

 

Stock TPS has 3 wires leading to and from. They connect to another connector. No extra box and no lights.

Sounds like you have a digital tuner on yours.

 

sounds like itcould be a electronic throttle response calibrator

 

Digital Tuner? Hmm, not very knowledgable on those but after I removed it, the car drives the same. Should I hook it back up?

 

I've got to run, I'll check up on this later tonight. Please post any information on what this is, especially if your SURE you know.

 

Reads like a Casper......

 

Sweet Jesus thats it! Whats a casper?

 

A ricer mod to "bypass" system part throttle strategy in the ECM.....not worth it. It causes the TPS to become sort of a switch.....Closed Throttle-WOT....instead of CT-Part Throttle-WOT.

 

Well looks like Im keeping it away from my car then. Thanks, that had me puzzled...

 

Ive seen them things before but never knew anybody to ever use on.

Ever notice how so many ricer mods dont seem to be worth the money??? I know they sure dont.
