Just curious but is there a specific reason you don't wan the vehicle in dyno mode? I understand if it is impossible to activate without STAR that might be a reason but other than a few button presses on the steering wheel, it isn't difficult to activate I think?

Because I do not have a limited slip rear diff and in Dyno mode only one wheel gets the power but with traction control "off " the ECU will balance out both rear wheels.
My thinking was it will not hook up on the Dyno rollers under full power and Nitrous on just one wheel but I know both drums spin together on the Dyno so maybe it will not matter.
Have been on the Dyno with many cars but never an E55.

You need to remember that when the car 'balances out" both rear wheels it is doing it by applying the brakes. That will negatively impact the power numbers. I would not recommend it.
