You forgot to add.. Sprinkle demon powder all the way around the car..

There is a little known-simple method for dyno runs though..

And I had read the write up about "jumping" the sensor inputs with a harness... and had actually sent that to them when they were "help .. can't get dyno run" at one point.

It almost seems like Mercedes went out of their way to make things highly complex..

For dyno mode, just jack the back wheels off the ground and put it in gear. Let them spin for 60 seconds and voila, dyno mode. Just like pulling fuses on the 05+ and pulling the wire on the 04's, you'll lose ABS but you wont have the 4K RPM limiter.
