bootmod3 S63TU4 ECU Tune for BMW M5, M8, X5 M and X6 M
bootmod3 is an advanced cloud-based ECU flash-tuning platform developed by ProTuning Freaks for BMW M vehicles equipped with the S63TU4 engine, including the F90 M5, F91, F92 and F93 M8, F95 X5 M and F96 X6 M.
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 bootmod3 platform also provides access to advanced map customisation, high-speed datalogging, Live Dash monitoring, diagnostic functions, cloud storage and professional custom tuning for upgraded turbochargers, ethanol blends, Race Gas and additional injection systems.
Whether your S63TU4-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.

DME Unlock Requirements
BMW S63TU4 vehicles may require an OBD patch, Bench Unlock or another supported DME unlock method before bootmod3 can flash the factory DMEs.
Vehicles running November 2019 or newer DME software may require an unlock or patch before OBD flashing. The exact unlock requirement depends on the DME production date and installed software version.
Earlier vehicles may also become locked after receiving a later manufacturer software update. Unlock requirements should therefore be confirmed using the vehicle’s VIN, DME production date and installed software version.
Contact EURO TUNED before purchasing and send us your VIN or vehicle details. We will check the likely unlock requirement and explain the correct process.
When a DME unlock is required, EURO TUNED can arrange the required unlock through our trusted specialists. The exact process will depend on your vehicle, DME and software version.
Once unlocked, EURO TUNED can complete the bootmod3 activation, software setup and installation of your selected OTS map.
