I have since sold my M8 and purchased an G82 M4 Competition. I spoke with DME Tuning yesterday concerning a tune. They have an M4 Competition they are using as a "test" car and hope to have a fix within a couple of months. In the meantime I have ordered a JB4 to play with until I can have my car tuned. I would go with Bootmod if they are first with a fix.

Try Carbahn tune by Steve Dinan. He might have an answer. I have Stage 1 in my Z4 M40i and now have 471 HP and over 500 pounds of torque. With the weight of my car its an M3 killer for sure! Most M3's 4k pounds. The Ecu will be cracked and with AWD (mine on order) what a beast that will be.

Really hoping this ecu gets cracked this year.. a lot of money to be made by the tuners and other vendors when this happens. Until then- how far can we push the car w JB4? E85? Turbos?

The last several generations of DMEs have all first been cracked by Mission Performance my money is on them.
And considering they do work for Toyota Corp on the TRD Supra they are top of their game Also understand they are getting close to launching an entirely new tuning platform of some sort so the innovation seems to continue to be flowing out of their doors Ps- in speaking with them I understand that they did just enable 2wd via idrive on a 21 X3M (previously they only offers that on 20's) so that's a baby step in the right direction |

The only problem is my charge pipe blew (because N55 things), and Carbahn wouldn't cover it even though I paid for the warranty. They said take it to the dealer. Took it to the dealer, and of course when they scanned the car they could see the DME had been modified so they refused to cover any of it. Thankfully my local shop that did the Carbahn flash ate the cost and took care of me. Likely the first thing I'll be looking at once I'm out of warranty though. One the ECU gets cracked I feel like this will be the most customized flash route. (but will likely go race chip in the mean time) |

Even so, this is a good reason why the extended warranty that's offered is a good idea. It actually is underwritten by a 3rd party and is only used if BMW denies the first claim. They don't have access to BMW's computers so they wouldn't be able to pull those logs. At least, this is what a BMW financing guy told me

And 3rd party will absolutely contact the dealer to find out why the warranty claim was denied. Buddy had a F80 M3 that he accidentally over-revved at a track day and BMW USA denied the warranty claim for his blown motor due to the ECU data. 3rd party (Zurich, I think) talked to the dealer and denied the claim due to abuse or something along those lines. The only way it got covered was a two month long battle with BMW Corporate and I think lawyers were involved... |

Why would anyone do a piggyback over a flash tune if both are available? If it's gonna get denied anyway, may as well make the job simpler.

I just read that a piggyback doesnt allow the DME to see the modified numbers (ie boost is at 20 but car thinks its at 15). In this case, how can BMW see it has been tuned?

For one, the TCU measures torque and if it cuts torque because you bang off the limits its recorded. There are other traces in the various other sensors. I believe the MAP sensors also measure absolute pressure so even tho the boost sensors are fooled and control boost i think other sensors can see the actual boost made.
