Anyone know how to code out E82 135i e-diff in NSW/ACT

My 2008 E82 135i manual is fitted with a Quaife LSD and is regulary run on race tracks. Despite turning STC and DSC off I am still getting a loss of power when exiting corners.
The nanny effect is not as bad as having the DSC switched on but it causes a noticeable reduction in acceleration. A friend in a 130i recently followed me for a couple of laps and swore that he could tell where the e-diff intervened as he could see the pauses in motion and closed the gap each time. It is a real pest as running on R-spec tyres improves traction to such an extent that it is not dangerous to turn the nanny controls off. I understand that the re-coding can be done using NCS but I need to find comeone who knows how to use this program.

There's a thread on another forum that outlines how to add a M3/1M DSC to a non M car. I was a member of a group that worked to put M3 DCT drivelogic on a non M N54 car and it all works. You'll likely need the DSC, maybe a steering angle sensor and some tricky coding. If you want more info let me know.

You can do it with an app now - bimmergeeks. Makes it 10* easier than ncsexpert (which isn't all that hard, but can take hours to get the bloody software working with the right combo of cable/laptop/VM etc..)

Protools is the simplest way to code out E-diff
