I'm now of the opinion that the Auto-Stick versions don't get the 5,000 RPM limiter kick-in like HDDP's and others. It may be an engine protection feature that senses the front wheel speed and then determines whether the engine rpm is too high. Derek tried with the ESP fuses pulled at the track and still had the 5,000 RPM drop-out, so I think it's only on the Manual transmissions.
Would be interesting to know if you could take the Auto-Stick ECU and put it in a Manual Transmission vehicle and get rid of that 5,000 RPM drop-out.
Cheers!
I think you are correct about it being a manual transmission protection feature that is not necessary on the auto. I think I have this problem licked now though with an electronic widget that simulates Golfdude's front wheel spinning shenanigans. I will be back at the dyno to test it for real when time permits. ...As an aside, I just watched tonight's Fifth Gear and Tiff was at the MB test track testing an AMG ML 'something or other'. On the skid pan he was fighting the ESP so an engineer cam out and 'entered a secret code' and completely disabled it - it was sideways all the way after that!
