Gen 2. Cam, upper and lower pulleys, intake, full exhaust, drag pack. 693/695 on E85. All that and hardly 0.3 faster in the 1/4 versus the stock M5 time I've gotten. Lol. I've got so much hope for this platform if a tune will just take.

I'm leaving today to drive 4 hours to Alpharetta so they can return the car back to "stock" and refund me. Was supposed to be last week but the German engineer had a medical emergency so it was rescheduled. I plan on trying out a BM3 OTS tune when I'm back home tomorrow or Saturday to see if that even works and will report back.

Nice. Now I can't even use the car. It won't start now. So BM3 failed as well. Tried force flash and unlock like it said and then got the same error. Guess I'll try recover…[IMG][/IMG]

I don’t have any other ideas. I use a power supply instead of a battery charger but the charger should work though it is not the ideal choice. I just attach under the hood to the jump start terminal and ground. Never seen the battery in the trunk before. Looks like there is a little space there to store tools or little used items.
I assume you are precisely following the flashing instructions in terms of not opening doors, etc. XHP tells you to gave the seatbelt on, but I don’t think BM3 does. Door has to stay closed. |

That sucks. I have read about newer ECU needing to be unlocked but maybe Dinan and Noelle unlocked to flash and then relocked so a BM3 would not work. I assumed the flash would simply not occur though rather than leave you stranded.

In the main menu, it says that it's unlocked and ready to flash. That's why I tried it. But I can't flash to stock and re-lock because of the software being new. It's big suck. Lol. Not surprised though.

I would try charging the battery overnight and then flashing again. If you read up on power supplies vs chargers for flashing there are some differences. These cars can draw more amps than the charger puts out and the charger is not as stable and may be at higher than desired voltage. Some expensive chargers do have a flashing feature though.

Man, I can emphasize. I got stuck at a gas station once switching between tunes. Unfortunately there's no 24/7 support. Hopefully you get this all figured out.

They replied to 2 emails in an hour and 15 minutes before they closed- after I asked for them to even call me or to remote in with TeamViewer, etc. The extent of the emails was to take a picture of a screen with software ID's and nothing after that. Shitty customer service. So it's dead until next week when they can figure something out. I just tried every flash option to no avail so I'm done messing with it.

Do you get error messages when flashing? Like powertrain and stuff? I have one for engine oil, too. |
