2013 F12 650ix wont upshift in Sport+
Hi All,
forgive any formatting errors im new to posting on forums and sorry for the long post I just want to give as many details as possible... A few weeks back I decided that I wanted to make more power in my 2013 F12 BMW 650i xDrive N63TU, so I purchased an OTS Stage 1 93 Octane map from Bootmod3. I have used Bootmod in the past on not one, but two BMW X3's and never had any issues, so I thought it was a no brainer to use them for my 650. I Flashed my ECU with the tune and definitely noticed the power upgrade, However there was one problem. The car no longer automatically shifted in Sport + mode. I contacted Bootmod3 support and they said they've never experienced a problem with the transmission on this car and they don't offer a transmission tune because it should be fast enough. Some Notes:
any ideas as to why this is happening and or how to fix it? Thank you !! |

Can't give much help but from what you posted I'd say that the tune had nothing to do with it. Just because B followed A, doesn't mean A caused B.

Thanks for the Reply!
It just seems weird to me that the cars fine in every other drive mode... I've tried googling the issue for a few hours now and no luck. I did find that there is a way to "Factory reset" the transmission by putting the car in accessory mode and holding the gas pedal all the way to the floor for 30 seconds. I think im going to give that a go, but if that doesn't fix my issue then im completely stumped here |

Weird that you brought this up because I just noticed this the other day with my 2013 650i bm3 stage 2.
I was testing launch control and noticed that it did not want to shift from S1 into S2, the RPM's just stayed at redline, didn't bounce off the rev limit. It shifts fine at WOT every gear after. I read that if you let off the kickdown button at WOT at any point then it stops auto shift. I will test this out later and see. |

Is the shifter toggled to the left or to the right? In manual mode, (toggled left) and Sport+, the auto upshifts are disabled. Not so in any other mode though...

I've tested it with the shifter toggled to the left and to the right. To my understanding -- and correct me if i'm wrong -- when the shifter is pushed to the left the car is in Automatic Sport Transmission... unless you manually change gears up or down, it will remain in automatic sport transmission Nevertheless, i also tried it with the shifter just in Drive, same outcome. |

What Walt said... Left is manual, right is sport auto. Left will upshift except when in Sport +, but right and Sport + should upshift. Just make sure you haven't enabled manual mode via the paddles. |

So if i’m in sport transmission with sport plus it will automatically be in manual mode, without having touched the paddles or upshifted with the gear lever. i.e not shifting up unless i do?
That also doesn’t explain why my car shifts by itself if I don’t hammer down on the gas pedal in sport plus and lever to left Something seems odd |

I see this as a positive, I would prefer car didn't shift by itself, that's what driver involvement is for. Use your paddles and take control.

seeing the car act this way is very strange to me and I see is as a problem. Regardless of the severity, I'm just trying to get the car to act as it should. |

Ok so I tested out my launch control again tonight and it still won't shift into 2nd in S shift mode. Car shifts fine when I don't use launch control. I'll try resetting my transmission adaptation.
Side note, launching without LC felt much more powerful. Using LC makes it feel so sluggish. Edit: Car won't shift into 2nd in S mode without LC either hmm |
