Car won't start after flashing BM3 Stage 1

BMWSauberF1 · 09-16-2022, 06:50 PM

Hi I just purchased a BM3 license and tried to flash it today but after flashing it on multiple computers using the force unlock and regular flashing options it still won't turn on it cranks but won't turn on until I flash back to the stock map then it turns over.

Need more context and details of what's going on

After flashing the tune the car won't turn over. After several tries with multiple computers. I always have to end up flashing the stock map back for it to be able to start again.

Does the tune complete ? Does it stop half way?

A buddy of mine had the same problem on his F8X, make sure you use a trickle charger so the battery gets enough juice and doesn't end up dying out. That worked for him but contact support and they shall square you away as well

No it was completing. They just ended up having me do the force flash option and flashing it twice in a row I believe they said they made a change to a file for me as well. But after flashing it back to back with the tune it works. I just have a bunch of misfires now once I'm WOT over about 4k rpm so I just ordered some new NGK's and will be gapping them to .22 and installing tomorrow.
