Rev Matching Inconsistant
Well I think I am having issues with this "super duper rev matching assist", I have only had the car a week now and I have been driving on the defaults until this morning. So the rev match feature sometimes works and sometimes not, I do not get it. Sometimes I would have to blip the throttle when downshifting and sometimes it would do it for me. It seems like it rev matches when the clutch is in and you downshift slowly. Now fast forward to today and I set everything on sport plus (feels more like my old e46 m3) and it wasn't rev matching the whole drive to work until the couple last stops where it would rev match very aggressively, sounded nice but I either want it to work 100% of the time or not at all.
Sorry if that was all confusing as I have not had all my coffee yet. Any way to completely disable rev match feature across the board? Nick |

Efficient & sport throttle mappings = rev matching
Sport plus throttle mapping = no rev matching The times that rev matching doesn't engage is when I hold the clutch in to coast and eventually downshift (e.g., coasting to a red light with the clutch in, light turns green, downshift into a lower gear = no rev match). To account for this, you can double clutch and it will reengage rev matching. Otherwise, it's been rock solid for me and works as designed.

It is disabled in Sport+ however in sport if you are in 2nd you can downshift to first and it will rev match

So you're saying the rev-match feature is unpredictable....sometimes functions as it's designed...sometimes it has a mind of its own?
This is one of my many videos highlighting this issue. Might be hard to see but it is in sport+ and my foot was no where near the accelerator. Last edited by domd817; 10-23-2015 at 05:33 PM.. Reason: video addition |

Efficient mode seems to tone down the rev matching feature. I don't think it will rev match 2nd to 1st in this mode. Sport mode seems a bit more aggressive and I think it will match 2nd to 1st.

My recommendation. ..Don't get a manual if all you intended to do was let it rev match and do the work all the time. Just my .02.

OP, I've noticed mine hesitating a handful of times. Once causing me to drop the clutch, because of muscle memory, and shocking the drivetrain. I'm not sure what the deal was... guessing some kind of processing issue with the gear select sensor. |

It's seems like it's just more than me that is experiencing the issue. It doesn't make me go to bmw to show them an issue that happens "sometimes", I love the car other than this small issue. I think I will just look into trying to code out the rev match or something so it is completely off. I have no issues with driving a manual I just want to know if I would need to throttle blip or is it gonna do it by itself, 99% of the time I'm not driving hard enough to downshift quickly to make rev matching a big deal.

These are all really helpful comments guys, keep them coming! Edit: Also, with that reasoning, wouldn't it be lazier to have a dct? |

Another worthwhile thread goes down the drain due to some wasteful comments. This isnt a dct vs 6mt thread. There are plenty of those to go around.
To the OP, take a look in the coding forum, there is a thread regarding coding out rev match

Anyway, I'm going to reach out to my SA about this and let you know if I find anything out. I would imagine a software update could remedy this. |
