How to Remove the Soft Limiter

LSA · 09-13-2020, 12:42 PM

What are the options, if any, to remove the soft limiter on an automatic 10spd ZL1?

Is there an OBD tune that will remove the soft limiter?

The engine rev limiter and speed limiter are both programmed in the computers. I’m not aware of any OBD device that can override either one of them.

I did it for my m6 with hptuners. Took a few months to figure it out. Im not sure if it would work for autos

Ya I believe it was in adjusting the hysteresis to around 50 or 80rpm and the key was increasing the torque command in the cut off so that it doesn't pull power at the limiter. Took a while for me to figure that out last year sometime.
