2002 jeep wrangler tj 4.0L BBK Throttle body TPS not accurate

[MJs02TJ]

Hello Everyone, i have a 2002 jeep TJ with 4.0L, i have the BBK 62 MM throttle body and i notice that in the Viewer that the throttle position starts at 14.1% and maxes out at 76.1 %, the mechanical pedal action does go to zero and is wide open when pedal is depressed to floor. i dont see a way to calibrate the TPS in the JTEC+. Anyone else have this condition with BBK throttle body.

Update, i pulled out the OEM throttle body, installed the TPS on there and the accuracy was still off, now its 10% fully closed to 71% fully open. Ordered a new Mopar TPS, hopefully that will get it correct.

I have almost the same readings on my 2001 Grand Cherokee 4.0, it only changed by a percent maybe after putting a new TB 62mm and an NGK TPS. I think its just the way that it is, and all it needs to do is read smoothly from the min to max reading without jumping erratically in order for it to run correctly.

I think the low reading is governed by the IAC and it's bypass capacity. I see 13.3% on my '04 TJ. Not sure about the TPS at fully open but I recently installed the same BBK and can give you my results. Not 100% sure if it was WOT but I grabbed a screengrab of Torque app at 77.25% where I think it was. TPS has been fine and I saw no change in performance when I installed the BBK 62mm.

My initial response was when I was just scanning with my ODBII scanner on Torque on my phone. I've since been running some scans on HPTuners beta version and I do see idle TPS at 0% and WOT at 100%. Not sure why the app was reporting in a narrower range but I think a new sensor is in order. They are a known point of failure.

What was the result after installing a new tps? I have a similar tps readings using the OBD Fusion app. I also have a BBK 62mm TB installed.
