So my TPS reads 101% on my Quadzilla Adrenaline tuner, and 100% on my Edge w/Attitude all the time. If I unplug the Data-Link connection it reads 0%. My truck always runs as drives as it should. And it does this with 2 different apps sensors. My APPS is under the drivers-side battery.Anyone have any idea what's causing this??

If it driving normally and not having issues this means that for some reason the Quadzilla and Edge Juice can't see the APPS signal properly.

Anyone have an idea how to fix it?

What year truck do you have????? Fill out a signature so we know. When I ran the Edge J w/A, there was no connection at all for the TPS. TPS is Throttle Position Sensor, correct???

It's an early-04 2500 QCSB 4wd, 5-speed manual. There's no direct connection for the TPS, but from what I can tell it gets read from the data-link connection. And TPS=throttle position sensor....you are correct sir.I can't edit my signature from my iPhone app, do I gotta wait til I get my computer back up and running....

The only that I can remember from my Edge days was the "%Load" that I could display on the "Attitude" screen. From what I remember; that was the % of "fueling" that the "box" was doing at the time.It sure does sound like you've got a faulty connection somewhere.I dunno how to fix it either, because you said it was the same with 2 different units!!!! I dunno man!!:banghead:
