So, I have a customer that is dead set on doing burnouts in his 2011 6.2 Raptor, roush supercharged. When on the brake pedal, the truck will not allow the throttle blade to stay open at WOT. I assumed there was a switch somewhere or a max torque scalar to control this but I've tried everything I can logically find and it still does the same thing. I've read a lot of posts here and elsewhere about this problem seemingly on Raptors specifically, but no real solution is ever found. Advance Trac is turned off for each attempt. Tried from D, M, and 1 shift positions, offroad mode, etc. thinking it was ABS/Traction related.
Does anyone know (and is willing to share), what in the calibration is limiting this?
I did the same thing in my 14 F150 Ecoboost (bone stock) and it lights up the tires with no problems.
Maybe it's not in the PCM after all, and lies in another module?
If we roll the truck out without brake pedal, it gives full throttle opening. It's only with brake depressed.
Now it's more of a quest to find the solution, just to solve the unknown!
