How it works (simple version)
1) Confirm support
Verify your exact A90/A91 model year and DME software are supported for BM3 flashing.
2) Get connected
Use BM3 WiFi adapter or OBD ENET cable. Keep battery voltage stable during reads/flashes.
3) Pick your map
Choose Stage 1 or Stage 2, then match the map to your fuel (91/93/E30) and any supporting hardware.
4) Flash + verify
Flash the selected map, do a quick test drive, and datalog if you want a sanity check.
Important notes
- Estimates only: totals use 382 hp / 368 lb-ft baseline and BM3 listed โup toโ gains.
- For E30 blends: actual ethanol content varies by pump and season.
- For off-road / motorsports use only where applicable. You are responsible for emissions compliance in your area.
