Drivetrain Malfunction in 1st with JB4
If I floor it in 1st too hard I get a drivetrain malfunction and the car won't move at all. I have to stop and restart for it to be fixed. Anyone know how to stop this? Been happening ever since I got the JB4.

I've had the drivetrain malfunction when I spin the tires, traction control engages, and I keep trying to go. sometimes it happens so fast that the traction control light doesn't get to come on.
just ease up in wet or slippery weather, your tires might be shot too. |

I don't just get the notification but my car just won't drive anymore. It just rolls and steers. No acceleration in first or second (haven't tried the other gears because it scares me lol) until I restart and it's all normal. |

Can you post a log? Does this happen on map 1 or 2?
I have had JB4 for a couple of years and had the problem you describe happen only once - hit the throttle, DT malfunction and then car wouldn't go and would barely idle. Had to shut off and wait. Restarted and it worked fine.

Map 6 is custom tune. Map 1-3 didn't run very well for me. I don't have a check engine light and restart the car instantly because it's always happened to me when I was in the road so didn't have time to mess around. I will try to see if I can pull a code before I restart. I'm gonna try to re-produce it in a safe road. Quote:
That's exactly what it does to me. Thanks for the help guys I'll hopefully get back to everyone soon with results if I can reproduce it. |

I think to find out what is going on you are going to have to get some logs. If you don't have the Bluetooth module for the JB4 you should seriously consider it. Between the module and app pricing it isn't cheap but you can have the app automatically log and you can easily change any settings on the JB4. The real time display is also well done. Prior to getting the BT module I had laptop on passenger seat. Worked, but was a PIA to set up and I never used it on a daily basis.

I’ve experienced this for quite a while, since 2016.
It happens to me when I’m hesitant with the pedal but eventually give full Throttle in first gear. I think it’s related to a torque/ecu issue. I can’t remember well, but our transmissions are limited due to some torque limitations right? Something a flash tune might fix? It’s a bit scary when it happens.. |

It's been raining today so didn't do it. It would probably work but don't wanna risk sliding or something going wrong. Quote:
You have just lived with it? It's getting me worried like today I was going to make a u turn in traffic and had to wait until there was absolutely nobody because I was afraid to punch it. |

The auto logging works really great. I set mine to auto log at 80% WOT, so when the pedal is over 80% it starts logging. WOT timeout I have set to 3 seconds.
Something is definitely not right if you are getting that many DT malfunctions. My experience with DT messages are limited to the N55. Occasionally I get one at startup, and have to shut the car off and turn back on. Also very occasionally I will get one while driving but there is no issue and it seems to clear. Only once I had the case where the engine would only barely idle and it was somewhat alarming to say the least. Good thing I was just on a street with not a lot of traffic and managed to pull over. If you can get a log when this happens BMS is great about support. Post in the B58 support section and usually you get a response within a day. Even if you don't have a log you could post the question - but usually they always ask for a log.

The DT message doesn't happen a lot while normal driving, just in the specific case that I listed. Couple times taking a turn from a stop, one time doing a u turn, couple times from a stop after rolling first then abruptly going WOT. Always in 1st while WOT that's it. Hope I get a chance to do some testing soon. |

Looks like DT malfunction has A LOT of different reasons. This could be really annoying to figure out lol |

I took my car into service since I had a close friend working there. He couldn’t find the issue, but said the cause is probably from the JB4. Not that the JB4 is doing something wrong or causing damage, but a possible issue between the piggyback and our b58 limitations. Yes, I’ve lived with it. I have put 40,000 miles on the JB4 and Intake. Probably received about 10 of those malfunctions within a 2+ year time frame. No issues, knock on wood. Have had the DP for about 35,000 miles. Multiple e85, 100 octane and octane booster mixes as well. This issue really sucks when it happens around other cars. Especially when they’re honking at you not knowing your car won’t move until you turn it off and back on again. |

My car did this for the first time today. Been running the JB4 for about 25k miles and never had the issue so caught me off guard.
Using bimmercode, I did some changes to the front module like folding mirrors, etc. just yesterday. Since I did that, I feel the car stutter a bit which i thought was odd. Today I put my AS wheels back on (put the factory ones on for a comparison at the strip) which is normally what I drive on without issue. However, coming out of Walmart, like I’ve done a million times before, I floored it after I started going straight and then the DT malfunction triggered for the first time and cut all power. Thankfully there was a turn lane right away and I coasted into it and parked. Quick off/on of the car and it cleared fine. Driving away I gave it a half throttle and felt a little stutter again and then went back to normal. Like I mentioned, I’ve done this a hundred times with my AS tires and never had any issues. Only thing different now from before is it’s 45 degrees out now and I did that coding. The image is the codes the jb4 read after this happened. What normally happens if I start to slip, TC kicks in, icon flashes, and power is blipped, but then it hooks and goes again. Never any error codes. The one code looks to translate to excessive acceleration from what a quick google search produced, but I’ve never had issues, even when I did an 1/8th mile in 7.76 seconds. What I’m assuming is the cause of this is excessive wheel acceleration/slippage that was beyond what TC is capable of correcting. As mentioned before, having colder weather here so the tires, although AS tires, are little firmer which means less grip. What someone said during my research was boost limiting in 1st and 2nd gear and that fixed the issue for them. Personally I went with wider tires front and rear and never had the issue until today.

I always have Tc light in 1/2 and sometimes 3rd. I have 245 all around and I think that's a huge issue. I might need to go back to staggered and run 265 in the back. I live in Florida where it's always hot but still have traction issues even stock. This car definitely has a good amount of torque. It's really annoying because I rather lose traction and be able to just take my foot off some than the car just die on me. However I don't drive around with TC off because I rather have that extra safety in normal driving. I just sometimes do as you did and make those turns floored. Now that I'm stock I should actually try to see if it'll happen before putting on the JB4. |

Agree 100% with driving with TC on. I daily Sport mode because Sport+ allows for (from what I’ve read) ~10 degrees of angle before it will cut power and I’d hate to get any angle near a curb. With Sport+ and DTC off, my xDrive will do donuts/drift so I know it will understeer me into any turn |

I think it makes sense that you didn't get the code till now because of you're xDrive. If you usually don't lose as much traction the cold could be a factor. Maybe it's a combination of not straight and no traction that gives DT malfunction. I have had so much TC issues going straight even in 1st gear with the light lit up like a Christmas tree but no shutdown. When the DT malfunction happens it's always a little turned and doesn't even have time to light up like that it dies so quickly. Now that I think of it before the JB4 I've peeled out in comfort mode doing similar turns multiple times even in the rain just with the TC lit up. Since JB4 the same types of turns give DT malfunction and only time I peel out is straight. It's probably a power handling issue with the ecu. I wonder if a flash tune can fix it? |

I’m stationed at Hurlburt and live out in Gulf Breeze. Haven’t been to the strip in Holt, but I did the 1/8th mile in Crossville, TN. Best was 7.76 at 88.9mph in the 1/8th which a rough translation is 12.1 in the quarter. No quarter strips around here that I know of. I’m on 235/265x19 Cont DWS06 so I was spinning off the line with track prep
