Those not happy with the 12b37 update

For what it's worth. After I had mine done there seemed like some minor occasions where the shifting was fine but for the most part my biggest gripe was the inconsistent behavior of where it seemed way too eager to shift to the highest gear possible all the time and wanted to lug/bog the motor.

Even while I'm accelerating from a light it would suddenly shift down to 6th way way too early and fall flat on it's face and would rarely drop a gear when trying to speed up a tad. Just more lugging.

Well I know there's been a lot of threads on the topic of the 12b37 update and I happened to catch where one person said something about having disconnected the positive battery cable for 10 mins and forced the car back into the adaptive learning mode. I didn't like the idea of having to lose all my settings and just never really put much weight into thinking that would ever work anyway.

Well about a week ago I was tinkering under the hood and decided what the hell and disconnected my battery. I purposely waited this long to make sure this wasn't a fluke but ever since doing that the DCT has been acting WAY different. It holds the gears longer when I want it to (while accelerating normally) and doesn't seem to try and immediately lug the motor. Also a little pedal action is all it seems to take now for it to drop a gear and help with slight passing, etc. Whereas before it would just Bog until a point that you've pushed the pedal down so far that it violently downshifts. Ugh.

It's still not a 100% though because every once in a while the perfect traffic situation will pop up where it may confuse the DCT with what I'm wanting to do and the 90 degree turns still doesn't seem to figure out what gear it should be in (2nd.. ITS 2nd!!! put it in 2nd Gear!!!) but overall a remarkably drastic improvement for me. It even seems to pull harder which is probably the a result of not shifting short of peak torque.

Just wanted to pass it along and see if anyone else notices an improvement. I just hope it doesn't revert back to it's old habits.

The only theory I can come up with is maybe there's some adaptive learning data from before that was still there and would take a lot of driving to work out or the dealer didn't take the time to wipe the memory, etc. who knows.

Oh and by the way. All your radio Presets, BT Phone, etc do not get erased. the MFT must have it's own battery backup.
