CL55 AMG (m113 N/A) poor low rev torque/acceleration
When I floor the accelerator from 0 mph there's totally no wheelspin and the acceleration is rather poor. Car starts running like it should from ~2000-2500 rpm. Then it accelerates absolutely well. I can even have a wheelspin (stabilization blinks) when flooring the accelerator on 2nd gear at 40 mph.
May be my 5gtronic is going to die soon? Will try to change the oil this weekend and make some performance tests.
Also I did try to reset the accelerator/gearbox adaptations. Runs better but still no wheelspin.

I don't think the solution has ever been posted
Trending Topics
- disabled all the safety systems ABS, ESP, BAS (as I have a coilover suspension and can play with fuses)
- reset the accelerator/gearbox adaptations to factory default values
- put gearbox on D and floored the pedal
- ... TONS OF WHEELSPIN! My rear tires were totally burned

That was 1st run after adaptations reset. Then I've driven a little bit and have poor acceleration again.
Conclusions: this is not gearbox or throttle, most likely accelerator pedal.
Bought one used from w220 5.0 2001 and installed it. Unfortunately it appeared dead. Now I'm in search of another pedal - will replace it and try to burn the tires
