That seems to suggest that the sluggishness is code for "need more powaaaaaaaaaa"

It's been difficult to find out what exactly that reset is - xHP told someone it was the "driver key memory", presumably learned "old lady" or "leadfoot" behaviour? When you don't know what you're resetting, who knows what might fix or alter it? I don't know if MHD or xHP improved my situation. If it was a transmission mapping reset, then it could have been xHP simply removing that learning function. If it was a throttle pedal learning thing, I set my MHD to "linear throttle", and maybe that wiped out the bad behaviour. I had my entire car upgraded a couple of iSteps since new so it shouldn't just be old DME software (which has been reported as part of the problem by BMW) so ANY tune might fix it. Who knows... I should try it just for kicks and see if I notice anything with both tunes enabled. |

All of the above. After a while (week or so) throttle response is increased, car shifts to higher gear sooner and as a result the car accelerates slower. Once I do throttle body adaptations reset, all of these issues are gone and car drives like it should for a few days.

After reset - super easy to be gentle, "confident" or aggressive - whatever you wanted. Then it learned to suck. At least that's the way I remember it. |

So - you still get this behaviour with MHD and normal throttle map?? If yes, that's interesting and the first I've heard of it. |

Do you use linear throttle or regular? |

I've solved this problem by changing upshift points in Sport mode in XHP to higher values (see pic below) so transmission stays in gear little longer. I think I'll add another 10% to 5=>6 shift point. The car now shifts gears exactly when I want it. XHP is well worth it

Just checked my I-step level and it is F010-18-07-530, which appears to be a year later than yours, so underlying software shouldn't be a problem

Never tried xHP though. I always wondered if it was some sort of "disconnect" between throttle and transmission. (No longer have the issue, as I've now got a '16 550i.) Dzz, did the xHP upshift adjustments make take off from stop any better? |

So XHP "fix" helps somewhat, but after doing the procedure for resetting transmission shift points, the car definitely feels more "lively" and drives better without annoying early upshifts. I am really hoping that this behaviour can be permanently removed or coded out. |
