bootmod3 (bm3) is the cloud-based flash-tuning platform for the BMW N20/N26. The N20 and its SULEV N26 sibling are the volume 2.0-litre four in the F-chassis cars. Factory tuning leaves a lot on the table, and a bm3 flash is the cheapest real power-per-dollar on the platform.
Flash from your phone or laptop over the bootmod3 Wi-Fi/OBD adapter — no bench, no dealer visit, fully reversible back to stock. The Ultimate licence is the full bm3 licence for your VIN and includes the complete off-the-shelf (OTS) map library, datalogging, digital gauges and DTC tools. The OTS Tuning option is a map pack only — it requires an active bm3 licence on the vehicle.
Fitment (N20/N26): F20 125i · F22 228i · F30 320i, 328i · F32 428i · F10 528i · X1, X3, X4 20i/28i · Z4 — 2.0L N20 / N26.

Off-road / competition use. ECU tuning may affect your factory warranty and emissions compliance — check your local regulations.
