BTW, just so you guys don't freak out when you get on the dyno, I'll tell you that my car had 3 or 4 different codes for the ABS system after my car came off the dyno. As soon as I started driving away from the shop they all were cleared. Maybe it has something to do with the car not actually moving or maybe dealing with the inertia of the dyno rollers slowing down
I just know I was a little freaked out until we left the shop and as soon as a drove maybe 100 ft all the warnings were cleared. No problems since.
