2) turn key to position 2 (everything on but engine off) and wait a couple seconds that the lights on the cluster finish turning on/off.
3) hold DSC button 8 seconds
4) press sport mode
5) start the car
6) rev car to limiter (it will stop at 6.5k, still)
7) turn off car
8) repeat 1) to 5). The car will now be able to rev all the way to 8k
I've done it and it worked ! it works only on pre 03( or 02/4 IIRC) M3's.
