Great! Now do this:I did this on my SLK 350 yesterday after reading the post.
I cannot believe the difference! Possibly the previous owner drove the 95000 km very sedately. The car has so much more grunt from standing start and seems to rev freer up to redline.
I will be doing this every six months or so, this was the cheapest performance upgrade I have ever done.
I picked this out of this very interesting thread - Two things come to mind. The adaptive learning on the auto transmissions does not work, everyone and I do mean everyone, is trying to get back to the default starting point. The mistake MB has made it that it thinks that if you drive your car around like a lamb you want it to adapt to that. I can and do drive my car around on occasion like a lamb and would be very unhappy for the car to adapt to that. Second the throttle response appears to have 1 of 2 settings. 100% at 70% position seems to be preferred and therefore I would say default. The mistake MB has made, in this case, is that the car chooses the position based on your driving style. The correct thing to do, would be to allow you to choose your throttle sensitivity as personal preference. The car does not know best and in addition you would actually know how it was set.I've read through this whole thread and sifted out the BS :grin:
There is confusion here between resetting the adaptive THROTTLE position and the TRANSMISSION changes.
The transmission adapts to your driving style and apparently cannot be manually reset - you're driving style will adapt automatically. What can be reset by the method described in the first post is the THROTTLE position. The throttle pedal is a potentiometer (2 in fact, one is a backup). That potentiometer "reads" how you drive the vehicle and adapts the position from zero throttle (zero%) to full throttle (100%) accordingly.
If you drive like Miss Daisy or always in slow moving city traffic then the throttle adapts to full throttle at 100% on the carpet. If you drive "spiritedly" then the throttle adapts to giving you 100% at around 70% of pedal movement.
What you do when readapting with the ignition key trick is bringing it back to the more aggressive adaptation (zero - 100% in 70% movement)
If you always drive in foot mashing mode then a re-adapt will do very little, if you drive a lot in city traffic and re-adapt then you will feel the difference. The auto trans will then automatically re-adapt itself to suit the new throttle values.
This THROTTLE re-adapt therefore should work with manual trans cars also

throttle? accelerator..... can u take it out in pos 2? try it and seeWonder how I missed this thread. I want to try this today.
Is the throttle pedal the brake or the gas?
After holding it down for 30 seconds, do you have to turn the key back to its original position before taking it out or take it out as it's still in position 2?
