TPS value not reading in HPTuners I can not get HP Tuners scan to display TPS .
I have 5 volt, ground, and signal at TPS,
even replaced the TPS, and still no display.
.
Also, what is easiest way to hook Innovate Wideband output data into wire harness, so that HPTuners can log AFR ?
Heard there is a backdoor wiring method, AC sensor... WHich wires can I use ?
Vehicle is 2002 flex fuel Tahoe.
Thank you.

re: TPS, do you have TPS voltage or position as a selected channel? it will not read in gauges, graphs or log any data unless the sensor is added to channels.
the same thing would apply to your wideband. you have to assign the channel and then define the sensor parameters. I have not done a wideband this way, but I've added a couple pressure sensors and it's not difficult.

well i should say, now it's not difficult that ive messed with it for a year.

you are using the 3.2 version yes?

The new 3.2 version made things much more difficult.
For TPS, you'll need to right click the table on the left and add a channel. Dig around for TPS. You'll need to make sure you get the one that shows % and not voltage. You have to do this before you connect it to the car.
For wideband, you pin into either the AC pressure port wire (Red 14 I believe?) or the EGR signal wire, and set up a custom PID in HPTuners. Takes about 10 minutes, there are a few how-tos out there.
