Default E-Diff and ideas on single tire spin

2010 XFR. I am looking for ideas on how to ensure the E-Diff acts like a limited slip or posi-unit on takeoff. Currently from an idle, and stepping on it , 4 out of 5 attempts wound up with the right tire going up in smoke, and this is at the track on a prepped surface. If it were spinning both, I'd live with it.
Dynamic on, sport mode, TSC off. Does brake torquing help with the E-diff psoture? I feel like that if I use the full brake/full throttle "launch control" (for lack of a better description) that it will be slower in E.T. So what am i doing wrong? Any experienced guidance would be appreciated.

Thanks, sound advice but I have already serviced the diff. I found.that if I do the burnout..then dry hop.and brake torque it before launch it is pretty dependable for a full on launch. I would sure like to meet someone that had been inside these and knows them inside and out.

I'd also like to wire a on/off computer bypass switch to the motor to interupt computer signal...and another two way momentary switch that could activate the motor. Flip off computer signal...then toggle the rear end to locked..make drag run, toggle back to open..then when done racing... flip back to computer signal.
now that leaves some questions... like will the computer take back over or would the synchronizing that's done at jag when you replace the electric motor be null at that point or function normally.
Just things I wonder lol
