bootmod3 N63TU ECU Tune for BMW 550i, 650i, 750i, X5 and X6
bootmod3 is an advanced cloud-based ECU flash-tuning platform developed by ProTuning Freaks for BMW F-Series vehicles equipped with the N63TU engine.
Supported vehicles include the BMW F07 550i Gran Turismo, F10 and F11 550i, F06, F12 and F13 650i, F01 and F02 750i or 750Li, F15 X5 xDrive50i and F16 X6 xDrive50i.
The platform provides direct access to ECU flashing, ready-to-use OTS maps, high-speed datalogging, diagnostics, map management and real-time vehicle monitoring through the bootmod3 web interface or mobile application for iOS and Android.
Once the required DME unlock has been completed, bootmod3 calibrates the factory engine control units directly through the vehicle’s OBD port. Supported maps can be flashed in only a few minutes, allowing the vehicle to move between stock, Stage 1 and Stage 2 calibrations.
One compatible bootmod3 OTS map is included with the licence. The appropriate calibration can be selected based on the fuel used, installed performance hardware and intended use of the vehicle. Additional OTS maps and professional custom tuning are also available through the bootmod3 platform.
The platform also provides access to high-speed datalogging, Live Dash monitoring, diagnostic functions, cloud storage and advanced map customisation for ethanol blends, Race Gas, upgraded turbochargers and additional injection systems.
Whether your N63TU-powered BMW is a standard daily-driven vehicle or part of a high-performance build, bootmod3 provides one complete platform for tuning, diagnostics, datalogging, monitoring and future upgrades.

Stage 1 ACN91 octane: up to 13% HP / 20% TQ

DME Unlock Requirements
Some BMW N63TU vehicles require a Bench Unlock or OBD patch before bootmod3 can flash the factory DMEs.
Unlock requirements depend on the installed DME software and any manufacturer software updates previously completed on the vehicle.
Compatibility for F01 750i and F02 750Li vehicles should be confirmed using the VIN before purchasing.
Contact EURO TUNED before purchasing and send us your VIN or vehicle details. We will check the likely unlock requirement, confirm vehicle compatibility and explain the correct process.
When a Bench Unlock or OBD patch is required, EURO TUNED can assist with the correct unlock process before bootmod3 activation and installation of the selected OTS map.
