FAQs

Can I calibrate my own car
Yes. Open your stock file, save as a new map and adjust, or collaborate with a tuner from the in-app directory.

Do I need internet to flash
Maps are managed online. Once a version is downloaded to your device you can perform the flash offline.

Is one licence valid for multiple vehicles
No. The licence is locked to one VIN. The OBD hardware can be reused across cars, but the software licence cannot.

Can I transfer my licence
Yes, the original purchaser can request a transfer. Previously purchased OTS or custom maps do not transfer. Contact BM3 support with your order number, current VIN, new VIN and ensure the car is returned to stock with the DME relocked before transfer.

Do you support E85 or methanol
E30 blend OTS options are available. Full E85 typically requires a custom calibration from a tuner in the directory.

How do I datalog
Use the mobile app with the in-car agent to record and review logs through the cloud.
