How it works (simple version)
1) Confirm support
Verify your exact vehicle and DME are supported for BM3 flashing.
2) Get connected
Use BM3 WiFi adapter or ENET cable. Keep battery voltage stable during reads/flashes.
3) Pick your map
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.
