2005 Silverado ETC pedal Position shows 155%??

[S2H]

trying to diagnose a problem....
ETC Pedal Position shows 155% when I put it to the floor
TPS(SAE) shows 100% when ETC is only at at 70, and pedal is about half way to the floor

trying to figure out if this is correct or not...obviouslly I'm thinking something is wrong...
Makes the throttle on this thing super touchy and nearly impossible to tune idle/return to idle


looking for somebody who has seen this and knows what I need to change

looks like customer has an aftermarket harness, I'm thinking maybe something is pinned incorrectly...but need to know if there is something that would make it read like this before I go trying to trace wires and repin this dam thing.

My 2005 Silverado DBW setup does the same thing.

I was hoping to have the ability to recalibrate this curve, but the tables in HP Tuners do not align (like, not at all) with what's going on. I'm very interested if we have the ability to tune these cals, but I have found zero information in the forums on how to do this with a P59 controller.

Full throttle at 2/3 pedal travel is kinda annoying...

You guys need to check the wiring and the hardware. My 2005 Silverado DBW is fine and doesn't do this.

What are you measuring for "ETC Pedal Position" when your pedal is pushed all the way to the floor?

100%
