I rarely have ESP/BAS intervention unless I'm out of control. It used to intervene when I had wheel spin at full throttle coming out of a corner or hitting a bump big enough to spin one wheel. With the wavetrac .... I'm trying to remember one instance where it kicked in and I can't.

Getting back to the dyno problem, I'm confused. I've read about troubles on the dyno and solutions but the only time I personally had a situation, it was caused by operator error. After the first "erroneous dyno" I found a AWD dyno and used it two times spinning the front wheels. Then, in the name of curiosity, I dynoed in RWD with the fronts stationary and didn't have a problem. Yes, the dash lights up like a christmas tree but cycling the key returns the lights to normal. I've had around 10 sessions on 2 dyno's now and never have trouble.

I'd love to know the cause of the problem when it's discovered.
