Disabling DCS torque reduction for road course track tune

imported_mega · 10-14-2022, 08:54 PM

All the regular nannies are off, but I still have a DSC torque reduction on 3rd gear or higher sweepers where the steering angle is more than about 10 degrees. As soon as the wheel is straight it's like hitting NOS.

I know some get around this by disconnecting the yaw sensor under the seat, I would rather run a tune that turns off all the reductions requested by the DSC, I do this with my R53 mini's and it's similar siemens code.

anyone done this? there is a section in the msd80 damos for TQM anti roll stabilization torque loss

I believe it has to be a coding change to the ABS computer first. I have no proof other than my butt, but coding mine to M3 spec seemed to make it more forgiving until it his a power reduction.

did you apply m3 settings via ncsexpert/ncsdummy? Can you share them?

I found that disabling ASR reductions in the ECU tune should effectively do the same thing, no torque reductions honored from the DSC. Unfortunately I do not have the hex address for I8AOS to apply it to my tune. The damos I have is for a earlier pre-release msd80 software version
