So there must be a mechanical servo to make it move to the right position and I would say the more power to the servo sent to it by the mechanical throttle to tell it where you want it. So is there a sensor feedback for that servo or whatever it is - then it would work in both ICE and EV and especially the data sent back while in EV would be great because you might find a point that if you go beyond it then bye bye EV.
Well you could make your own TPS xgauge and subtract 11 from the reading, but that still wouldn't change in EV. For the '10 and up FEH and Fusion Hybrid, there is a display (in the nav for FEH and instrument cluster for FFH) that shows how much power you can request when in EV before the ICE kicks on and how much braking you can request before the binders engage. It uses desired torque and compares it to a threshold that is a function of the battery SoC, temp, vehicle speed, etc. I have been meaning to data log the desired torque xgauge and see if I can determine where the threshold lies but haven't gotten around to it yet.
If you code up the desired torque xgauge and look at it as you're accelerating in EV or braking (should be negative for braking) it may be able to be determined what the thresholds are. Would also be a good idea to know how hard you can brake before engaging the friction brakes.
