6MT - Possible to code out clutch delay?

Hi,

With the M2 6MT there is a delay in getting onto the gas that is being controlled by the ECU after changing gear. Instead of a jolt in the back as the engine lays down it's torque, there is a slight delay and then a softness to how the ECU is applying the throttle (regardless of how much you are pressing the throttle).

This was there from the start, but not that bad in the OG M2 software, but following an update to more recent software (Istep: F020-18-07-547, so the ECU is effectively an LCI), there is a slowness to how the car puts the throttle down after changing gear. I assume that this is there to reduce transmission/clutch/tyre wear, but it would be nice to get rid of it.

Please can anyone let me know if this can be coded out?

I am almost certain that this situation could be improved by modding the clutch switch wiring (I have done this in a different car), but my M2 is still in warranty so I don't want to do that just yet.

Cheers.
