First off, when viewing TP% in EFILive, what PID should I be looking at? I am using Destroked's XFC with a ~0-5vdc input from the Dodge APPS.

I have configured the XFC to see the actual min and max voltage.

Here's where I am confused...when using the scan tool to read the TP% from the Cummins ECU, it is scaled 1:1 (0-100%) as I move the pedal. However, when using the scan tool on the Allison TCM, it is not scaled as I would expect it at all. For example, with the pedal position from 0 to about 20%, it translates to 0-75% on the PID "GM.TP". From 21-100% pedal position, the PID reads the rest of the range 76-100%.

I have not seen any way to scale the input in EFILive. So, the better question might be, what else is considered when generating the GM.TP PID? Seems like I have read something somewhere about the MAF sensor being in the mix.

Thanks for any help!
