It appears BMW with their first DCT software revision disabled "burnout mode" on the E9x M3 DCT transmissions, if you attempted a standing burnout the ECU will disengage the clutch when you hit the brakes, and may go into limp mode and throw a DCT warning light. ESS has the ability to enable the "burnout" mode with a software revision, as well as prevent any DCT overheating or limp mode.
Well over a year ago, when I initially took my N/A modded DCT to the drag strip I had the old DCT software, before the 1st revision and was able to do standing burnouts, no overheating warning lights. Here is a few vids below.
Not long after that, and even currently other DCT M3 enthusiasts had posted that they were not able to do a standing burnout. When I did my NA runs, I saw a SC'd M3 at Sacramento that was not able to as well, I was a bit confused by this because I was able too. The SC'D car would simply disengage the clutch when he applied the brakes and tried to heat up the DR's, it didn't make sense to me then, so I thought it was probably because of the power difference, between NA and SC'd that prevented it from doing so and the DCT simply did not like it.
A few of us, including me at the time, thought it was more of a hardware problem not software and that the DCT was overheating and possibly it needed a hardware upgrade, additional cooling, however as I've found out that wasn't the case, it appears to be a software issue.
It makes sense now, thinking back at the chain of events, AFTER my N/A 1/4 mile runs with the original BMW DCT software where I was able to do standing burnouts, I took my car to the dealer and had my DCT software and ECU software upgraded, this was just before I installed the Gintani supercharger over a year ago.
I then thought maybe I was running too much tire with the MT Drag Radials, and that it was simply having a hardtime doing a proper burnout with these DR's, lol. So I went with a smaller DR, like I ran when I was NA. I then tried this somewhat silly new theory about the tire size just recently at a private track event, but I was still unable to do a burnout, same thing clutch would disengage when I applied the brakes, the car still managed an 11.3 ET and 129 trap though, no slipping or overheating warning lights. After this, I was pretty sure it was a DCT software issue.
Now a year later, when I recently took the car to the strip for the first with the ESS kit and ESS DCT software, it no longer threw any warning lights, but still would not do a standing burnout, when I applied the brakes it would disengage the clutch not unlike before. The car did 17 passes that night, not much of a cool down between runs and the DCT never slipped, or threw any lights, limp mode, etc., worked great, but I still could not heat up the DR's, if you can't heat them they really aren't much better than street tires.
I then thought maybe I was running too much tire with the MT's and it simply wouldn't do a burnout, lol, so I went with a smaller Drag Radial. Then recently at a private event at Famoso raceway I was still unable to do a burnout, same thing clutch would disengage when I applied the brakes, the car still managed an 11.3 ET and 129 trap though, no slipping or overheating warning lights. After this, I was pretty sure it was a DCT software issue.
When I spoke to AJ and Roman about this, AJ said he would look into it and was confident that enabling the burnout mode was something he could do. AJ was able to remote flash the DCT ECU while Roman was in the my area recently, and walla the DCT is now able to do standing burnouts, no DCT warning lights as well. This DCT software that allows standing burnouts, still needs to be perfected but this is good news for people like me who do enjoy 1/4 mile runs and realize it's imperative to heat up the Drag Radials to get good traction and a solid launch while using LC.
Here's a vid showing the car with the ESS DCT software change and how they have the ability to enable the standing burnout mode with no overheating. It should be noted that my car has made over fifty 1/4 mile passes on this DCT transmission, NEVER has it slipped, it has taken a lot of abuse, and is still holding fine even with 586whp.
