BM3 anyone?
I had a BM3 stage 1 OTS tune on my X5 50i. I can't say enough good things about them. The difference in power was incredible. Anyone here have a BM3 or DME tune on their M40i? If so, how do you like it?
If you'd rather not comment here, please send me a PM. Thank you! |

I've tuned my 135i, but don't plan on messing with my future X4 in that manner. That said, my buddy who works at BMW NA has mentioned that a simple plug-in JB+ for the B58 even at default 50% setting doesn't throw codes and transforms even the heavy SUVs into rockets on the butt dyno.

If you're gonna tune it, might as well go for the full flash tune instead of just the appetizer lol. Regardless, and I'm sure you're already aware, any tune can void your power train warranty. Any flash tune is detectable with ISTA at the dealership. End of story. |

@freshxdough, did you have your DME bench unlocked locally in OC? I have the 20/07 software update that includes Android Auto and understand that the DME is locked and cannot be flashed by BM3 through the OBD2 port. Any advice on a work around or local reputable tuner here in OC that can bench unlock?

Does anybody know if the B58TU has been unlocked by pro tuning freaks to flash via ENET cable?

I've had BM3's tune on my '19 X3 since it came out. Installed with about 10k miles on the car and I've had it problem free the past 3.5 years and I'm just about to roll 70k miles. Started ST1, then onto ST2, and now on ST2+ with the TU fuel pump.
