Has to do with Dynamic Stability Control and ABS. When DSC/ABS is turned off it is not really really turned off

As far as I know you should also pull the ABS fuses (17 and 30 on an M5). This causes no data from the ABS sensors, making the ECU turn off DSC and ESP entirly Read this, it's about M5 but it also should apply for M3 http://www.m5board.com/vbulletin/e39-m5 ... o-run.html

We've had this issue before. More and more new cars are like this, thats why were getting the AWD add on for our dyno with where you can lock the rollers together so it spins all 4 tires for cars with this issue...

good for you. it seems there ar only two ways: getting a 4WD dyno with locked rollers (which you can'tz find in 300miles area) or find a GT1 diagnostic tool to put the car in dyno mode.
