Thanks! Definitely much better than the floaty stuff that was going on. What gears are those? Not sure what that jittery RPM is into the 3rd and 4th gears, may still be a little something going on or maybe it's just how the M3 TCU shifts look. If @BQTuning is still on this, might consider letting him play with the DME side tranny tuning now that we have at least one fully working setup active and see what can be done differently.On the way to get some fresh E85 last night I logged this for you guys. Proof the shifts are good
I'll work on a video soon.

I really don't remember, but want to say there was at least some weird minimum mileage limit before it would engage on the M (like 6.2 miles or something). I'm assuming that was just an alternate method of estimating when operating temp is reached. 135i TCU also seems to have a minimum mileage or temp and it seems longer for me than the 335is LC.Interesting about the M launch and temp. For non m I found that it probably doesn’t.
I specifically started and warmed up my car but didn’t drive far (200m max 1/8 mile) ie the trans should have been cold but engine warm and it worked

Whether it takes a diff swap or not in the end, glad it is working. Excellent work on this whole thing!

Thanks. Since these are first full force actually working conversion logs, just looking for an idea what looks different in logs and, of what's different, is it something that can still be improved on. Looking forward to being able to muck with it on my car at some point soon I hope.Heh, that jittery stuff in 3rd is slight wheel spin. The jittery stuff in 4th is part of the M3's drivelogic integrated into the dynamic stability control. If you upshift and abruptly let off the throttle it disengages the clutch so you don't upset the car's balance. It sounds wierd but the end result is incredibly smooth transition from full acceleration to immediate deceleration. No herky jerky because the trans is keeping all that herky jerky from ever touching the rear wheels. This is the 3.15 M3 pumpkin.
And yea, I could engage the 335is LC on a very cold car. Here with the M3 logic running things I have to have a fully warmed car for LC to engage.

In the video, were you in D or M in the last portion?
Maybe its been addressed earlier but, is the speedo accurate ? Looks like its slamming gears nicely. Well done again @dyezak.
M mode
Yep. 6 is needed to active launch control and can only be selected with DTC off IIRC, otherwise you can only select 1-5.Nice... And are there different numbered settings in M mode? 1 through 6 or something?
