JB4 Settings and Launch Control
When running map 1, what additional changes are you guys making to the boost levels (or anything else for that matter) to get better launches?
I have been unable to get a clean launch in the car in any format (stock or flashed) because it spins, then cuts off, then says AWD malfunction. Last edited by Agonz128; 02-11-2022 at 06:27 AM.. |

295 and 305 wide MPS4S tires with under 1k miles on them. I live in Miami and this happens when it is in the 80s. I have properly set up for launching.
I guess I didn't make it clear... My question is extremely specific. |

The code clears within 30 seconds on its own every time. I've tinkered with the rpm for the LC and it loses traction around 5k rpm in first gear, then throwing the temporary warning.

The car would still have a record of the code it doesn't just disappear lol. Go get it scanned with a proper bmw code reader idk if your jb4 can scan it or not but scan it when it shows up and see what the car didn't like

The JB4 does seem to upset the launch control programme a bit. My best 1/4 mile times are from brake boosting as a result. I'm yet to try boost by gear to take some of the gusto out of 1st and 2nd.
