Bootmod3 tune, launch control doesn't work
I have installed bm3 tune on my m5.
Car feels faster for sure, but the launch control doesn't seem to work. I have tried both 91 and 93 maps but the flag doesn't show. I have to manually shift, it wont auto shift. I know how to use launch control and have used it many times, Stock and with jb4. Contacted bm3 haven't heard back from them yet. |

Be careful you might have made an oversight when it was flashed:
When you flash the car, all of your preprogrammed settings default back to stock... so pressing the m2 button (if you have preprogrammed it to engage launc control) won't work ... I made this mistake Make sure everything has been reset Select Sport plus across the board Turn stability control fully off Put inManual Reset m2 button If that doesn't fix problem, then it could be a tune issue |

Ok, thanks for the answer, so you changed some settings after car have been flashed? I mean some setting reset? Can you guide me how you are able to execute LC?
Casue a lot of people faced with the issue when LC doesn't work after flashing bootmod3 . Thank you.

So if you had M2 button saved as predefined settings that would allow you trigger LC it won't have same settings again. You can either re-set the button to how it was before flash or just manually put the car in DSC OFF, AWD SPORT, Gearbox in S3 and it will trigger if you do everything right. |
