Is BM3 still more power OOB than MHD? Help, need to pick one by Nov 26...
Hello,
(sorry, here goes again, comparing these two options) https://g20.bimmerpost.com/forums/sh...67&postcount=2 states back in Feb 2020, Quote:
a) Shell 93 octane (E10) b) Race 100 octane c) E30 mixture with Shell 93 Octane + Sheetz Ethanol , with setup i have: Active Autowerke high flow catted downpipe and DINAN free flow axle-back exhaust system. Eventually i may go with flex-fuel system also haven't decided between MHD and BM3 which of their flex-fuel system i end up going with. But until then i will have to switch maps manually depending on fuel in the tank. But for now, i need to pick one by Nov 26. Finding hard to compare between BM3 and MHD since they are both comparable, in both OTS maps, flashing capability (more or less) and logging (eg. knock sensor, WOT %, etc.), custom tuning support. BM3 seems to be little more mainstream than MHD, although MHD has been around lot longer i think than BM3. My pre-sale support experiences just Q&A's with BM3 folks have been good. MHD, not so good. I'm hoping both are good at technical support follow throughs. Local tuner that supports both MHD and BM3 is pointing me to BM3. I just want to make "safe" power all the way to stage 2. BM3? MHD? Help me choose, please............ Thanks. |

Thanks for that pointer.
I'm in RTP, NC area, and i'm familiar with John's work at his shop CES Motorsports. I wasn't aware he has helped and to pioneer the MHD OTS tunes for B58's. Looks like i'm heading toward MHD... I need to look at the data logging dashboard metrics available between MHD and BM3, whether these two are comparable, and i would think they should be similar if not same. |

Bm3 create their own maps and software. MHD buys maps from third-party tuners, this plays a big role in the quality of support in my opinion and it's in the best interest of these tuners to have the off-the-shelf maps with more wiggle room so they can charge for custom maps. both are good options and you'll be happy no matter which one you choose
