Does Tune only performance gets eventually adapted out?
I used to have a tune on my M3 and the power increase was noticeable. After a while I could no longer tell if I had a tune. Right before I supercharged it, I put back the original tune and it didnt notice any real difference change. It seems that the ECU has modified its adaptation to cancel out the benefits of the tune. I wonder if its the same for the C63? I assume not completely because the throttle opening changes should remain.

If you mean adapted out, do you mean still putting 420 hp to the wheels a year after I got it? No. It won't get adapted out. Throttle response and shift patterns will change with driving style though. Long trips will yield lazier shifts and slower throttle response (in general).

I've always been curious about this latter part - the "adaptation" that occurs within the TCU (IIRC) which adapts to someone's driving style. I recall reading how to reset this. But are significant changes to shift timing and throttle response really made? I tend to do a variety of driving, so just wondering. Anyone have any more info?
Now the reset doesn't make such a big difference.

If the hard shift goes away I'll be sure to report back.

When the car isn't reset for a while you'll start to notice. Mine, for example, started to have some pretty hard downshifts from 4-3. Unfortunately I tucked it away for the winter before the reset, but when I take it out again I plan on doing a full warm up, seeing how it drives, and then if it is still there I'll reset it and let you know.

Maybe the C63 tune which comes with physically opening the throttle more and the fact the Perf Pkg cars comes with higher HP will allow the tune to stay...

Sometimes I think it does, but take the tune out and you'll notice. Drive it for a week to get used to that. Put it back in and you'll notice and fall in love with it all over again.
Exactly the same reason why our wives should let us sleep with other women one week a year. Just one week. Its all we need.

I'd like to learn more about what parameters an ECU tune generally alters. The same for TCU adaptation. I'm just not sure where to find this info - any ideas? I've been enjoying my Eurocharged tune without other alterations for a number of months now, and my really well honed butt dyno (another factor never to forget, I'm pretty damn skeptical of butt dyno perception abilities...) doesn't perceive any changes back. Anyone know of any resources out there with info about ECU/TCU tunes and alterations?

Should not need to go to the dealer to reset the TCU.
Here's a thread that describes how with keyed and keyless ignitions.

I'll be trying this out when mine comes out in the spring.

Exactly what happened in my M3... when it was just a tune. I thought it was my butt dyno getting used to it. When i put the stock tune back I could not see a loss in performance. Did this not happened when I supercharged the car. I guess that was too much for the car to adapt out.

No tune. I know how to do the reset, I'm just not driving the car right now so there's no point. Waiting for this damn weather to move out and spring to come in.
