How do I FULLY disable Traction Control and DSC?
Vehicle in question: 2011 BMW x5 35d
Firstly, yes, I know that holding the traction control button for ~3 seconds turns the traction control and stability control "off." However, it's not truly off. Every time I try hooning around in the snow (especially drifting), the traction control cuts power and the stability control goes bonkers. I have reached out to XHP but they said that their flash is only for the transmission module and won't change the traction and stability control modules. I know this is a silly request, but drifting around in the snow is the most fun one can have in a car... I would like to turn it all the way off. And seriously BMW, why do you let lawyers run your company? Ultimate snow drifting machines my ass..... I'll be picking a tune and doing a delete soon. I'm hoping that one of the tuning companies can do this? I'd also like some coding done as well... Any shops in the PNW do this work? DUDMD appears to no longer do delete tunes. Pic of my smokin babe for attention. |

We have 3 dsc setting. On which is all the nannies. Traction, which is just pushing the traction control button, this allows some wheel spin but doesn’t let you get out of control side to side. Then you hold it down and traction is off “fully”. I think to full disable it from interfering you would need to do something like unplug the abs sensors, which could get you those one tire friers.
The problem with our e70 x5s is it’s an open differential that’s electronically controlled. So if you’re drifting around and it senses one tire spinning too fast it’ll brake and to send the power to the other tire. Really the only way I think this could be fixed to allow you to drift more reliably without the e-diff constantly interfering is swap in an x5m drivetrain/harness and code it, like someone on here has done, or install an lsd in the rear differential which is available. The lsd would probably feel better drifting around though because the x5m differential is still controlled electronically but managed mechanically, where as the lsd is all mechanical which will probably lead to more predictability. I have no experience with the x5m differential though so it might feel just as natural

Update: I've been researching this and here's what I found so far.
Per XHP, the trans tune has nothing to do with the traction or stability control modules. Per Keir Parsons of Aftermath tuning (also confirmed by DUDMD), a DME tune also won't change the traction or stability control modules. However, Keir Parsons told me that via Protool (or similar), I can code out the brake pad heating protection. There may be other electrical nannies, but I hope to get to the bottom of this via Protool. My theory is because we have an open diff (electrically controlled), the brake pads are heating up when I'm slideways and then shutting the fun down. Time will tell. I have ordered a Stage 1 DUDMD tune as well as Protool. I'll do a Stage 2 once I'm able to get a downpipe, but they're on backorder from VRSF and ATM. |

Thanks for looking into this so thoroughly and would love to hear if you come up with a solution. Its something that has bothered me so I looked into briefly after getting an ECU tune and TCU tune (xhp). I'm assuming that you've looked into xdelete by xhp as well - that is something I havent really read too much into.
If we got more snow in PA I would definitely be more actively searching for a solution. |

I was looking to upgrade vehicles recently, but my wife actually put it in my head to just "upgrade" the x5 a bit and keep it for another 3 to 5 years. So I'm going to spend some money fixing some of the quirks that have always bugged me... Plus, anytime my wife gives me the green light to spend $4k modifying my car... Upcoming mods: Immediately: Stage 1 DUDMD tune Protool coding In the next few months" Catted downpipe ABC delete Stage 2 DUDMD tune Trans tune |

Ultimately I chose DUDMD because I've heard plenty of good reviews, and his brother will likely be doing the labor (installing the dp and egr delete) for me. |

I tend to lean towards tuning companies that make the most power reliably. Santjer hands down has the best tune at any level. They have a highly modified street legal 335d doing high 9s @ 143mph, then an x5d with hybrid lp turbo, dual fuel pumps and 100% injectors doing mid 11s @ 117mph. Both on fuel only. I think you’d be hard pressed to find any of the other tuners getting near him even with adding adding meth or nitrous.

I've heard good things about DUDMD and he is local so if he (or his brother) is doing the work it would be more convenient. I'm sure you'll enjoy it.
I went with Santjer because of a couple conversations I had with him, and him stating that he prioritizes a clean tune, rather than just dumping fuel and hoping the air can catch up. AKA rolling coal. I absolutely love the tune. Hit me up if you're ever in the Seattle area and want to compare. |

I'm having same issue with my e70 x5m. I want to know how to turn it all off completely. Can't use 1st gear and even 2nd she spins up the 315 rears when it comes on boost but then cuts in the traction/stability control. I'm running x-delete too so the fun begins then bang its over. Any help would be awesome.. Mines tuned , d/p , intake , stage 3 gearbox tune , and x-delete so heaps of fun I just struggle with the fact it cuts in the way it does....
