bootmod3 (bm3) is the cloud-based flash-tuning platform for the BMW B48. Flash from your phone or laptop over the bootmod3 Wi-Fi/OBD adapter — no bench, no dealer visit, fully reversible back to stock. Every license includes the complete library of off-the-shelf (OTS) maps (Stage 1, Stage 2 and fuel-specific maps), plus built-in datalogging, digital gauges and DTC tools.
Want a bespoke calibration? bm3 has custom tuning on tap through the in-app Tuner Directory — no emailing map files back and forth. Stack supporting mods (downpipe, intake, intercooler, flex fuel) and dial in a custom tune when you’re ready.
Fitment (B48): F-chassis and G-chassis 2.0T petrol (120i–430i, 330i, Z4 30i). Select your exact model above.
Delivery & support: License is issued to your bootmod3 account within 1–2 business days of order. Australian bootmod3 dealer support. A bootmod3 Wi-Fi or OBD adapter is required to flash (sold separately).
Off-road / competition use. ECU tuning may affect your factory warranty and emissions compliance — check your local regulations.
