Lost Power
Have a question about active handling and traction control. Under hard acceleration with wheel spin does either active handling or traction control have the ability to reduce engine power or interfere with shifting? Recently while in sport mode and normal mode at around 60 MPH I floored the accelerator and at around 90 plus the engine lost power. This never happened before although I have not had the SC with a tune on the car that long and do not know what to expect. Should I be using a different driving mode when under hard acceleration?

Find a safe(super key word: SAFE) place to test, turn off the nannies (TC/AH) or put it in comp mode and try the same test (60-90mph), if the results are the same, there may be something wrong with the tune. TC should'nt interfere unless you're spinning and AH shouldn't interefere unless you're going a bit sideways.

I wouldn't say it can "remove power from the engine" I would say " it can modulate the throttle to prevent car going out of preset parameters within the TC/AH programming. But , there is probally better experts on this subject here than me, so this'll be at least a "bump" to the top for your question.

Hi Ron,
I experienced the same thing, I also found that my A6 would not shift with wheel spin and would hit the rev limiter.
I had Chuck CoW tune the Trans and have not had any problems.
He tuned it as an 08 and it shifts quick and hard as you want it to, ether paddle or sport, plus it down shifts just as sweet.
