    M156 CLS63 adaptation question with aftermarket tune

    General question, please.

    I have a 09 CLS63 AMG. As I understand, it can be tuned using software or ECU flashing. What I'm wondering is that, after the tune, since this car has adaptations, despite the tune, will the tranny somehow go back to "hog mode" if not driven hard all the time? Or will the tune/flash always override the adaptation process and prevent it from "going soft"?

    My understanding is that the flash will always be there as those parameters affected are "hard" set and the adaptations won't be able to override them.

    mercedes and other cars will always learn your driving habits and adapt...there is no way around it. But remember you can always do things like the pedal reset to remove those adaptations.

    So, Jake, will the tune affect shift points, too?

    Can you give me any specifics about what the tune does, exactly? I realize that it boosts HP and torque, but how exactly does it do that? Would love specifics, please.

    Thanks!

    @DD GT3 RD had some issues with adaptations on his tune as I recall.

    sure does. Like all tuners, we modify things like air fuel, timing, redline, throttle response, and open the throttle body a little more. You will have more low end grunt, a nice exhaust tone, as well as saving a little bit at the pump.

    My car adapts like a mf in order to reach its full potential say at the drag strip you need to take say 10 runs before it wakes up, even resetting it doesn't really unleash it to its fullest, just beat tge smog out of it as much as possible

    Sounds like a pain in the ass honestly.

    I'm not trying to be a smart-ass, but what is the point of a tune if the tranny can revert back to "hog mode"? I don't drive the snot out of my car all the time, nor will I ever. It just doesn't make sense to have to drive it hard all the time to keep the tranny shift points crisp. Frankly, I hate this adaptation stuff. What's the point of having a high-end car with lots of power/torque and then having a suboptimal tranny/gearbox that adapts and doesn't allow full potential?

    I wish there was a tune that prevented adaptation and allowed the car to be crisp all the time without having to worry that if you drive if softly for a while that it'll stay that way (unless you either do the pedal reset trick or drive the crap out of it all the time, both of which are annoying/impractical).

    so a members c63 was tuned. dyno'd around 350-360whp stock. Had it tuned read 410-420whp. Came back a few days later to dyno again just to see and it dyno'd around 380-390. Reflashed it then and it went back up to 410-420whp.

    My car, a p31 c63 read around 380-390whp stock. When tuned 410-420whp. I never dyno'd it again but im sure if I came back it would of been at 380-390whp like the above car.


    My car felt faster after the tune but it was only due to the increased throttle response. I wasnt actually faster

    You are a P31 so you have a more aggressive tune from the factory.

    My main question is how do you keep the car at 420 whp or else isn't a tune kind of pointless if it just disappears a little later?

    If the tune is too agressive timing wise it might not knock on the dyno but knock on the road due to the increased load. Hence, the timing adapts and you throw that 20 odd whp out of the window which you shouldn't have anyway if the car is to knock in real world conditions.

    this I know. Point is that the non p31 got up to 420whp then went back down to 390whp where my car is stock...
    my car also showed a gain of power up to 420whp but Im sure it went back down to 390 and the tune did nothing.

    not sure if its adaptation or just bs.

    Likely adaptation. The question is how do you keep the power.

    well dodger was saying his power goes up when drives hard, that it takes 10 runs to get it going. How come our power went down? Its different. The power level its reading on the dyno is higher at first for some reason, a reason the car cant maintain probably cause it isnt good for it

    Perhaps but then does that mean the dyno runs are kind of useless?

    Few cars i deal with are like this on the dyno. Tuned or not.

    Mbz me9 family, m3/m5 mss ecu, audi me9 cars. Need to do 5 or so runs for power to level out.

    In some cars full timing is not forced om the first run. You need to satisfy criteria and hard driving to get it to move "up". In some vehicles it is called the ignition advance multiplier.
