bootmod3 (bm3) is the cloud-based flash-tuning platform for the BMW N63TU. Two turbos, 4.4 litres and a very conservative factory calibration. The N63TU picks up serious torque from a flash alone, and it is the tune that makes a 50i feel like the car the badge implies.
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 (N63TU): F01 750i · F10 550i · F12/F13 650i · F15 X5 50i · F16 X6 50i — 4.4L N63TU V8.
Delivery & support: 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.
