VR Tuned ECU Flash Tune BMW 550I F10 F11 408HP

Tuning the ECU of your BMW 550I F10 is possible with VR Tuned. Tuning this ECU requires special hardware to connect to the ECU which we have. Superior to a plug and play piggyback, we can transform your turbocharged engine into a beast. The driving characteristics are vastly improved while providing you additional benefits that your engine craves for. With this additional programming to adjust your ecu calibrations, we also make changes to the torque limiter to provide better throttle response.

How to Flash Your ECU?

• Use our OBDII VR Tuned iFlash Cable. This REQUIRES a Windows PC. The iFlash cable allows you to read and write your stock and tuned files. See Instructions Here.
• We can bench flash the ECUs. To bench flash the ECUs, you must remove it from your vehicle and send it to us. Once we receive the ECUs, we will prepare the tune file and then ship it back to you for reinstallation. We do not solder or modify the ECU board at all. All ECU tuning is done via bungy probes that have a needle tip to provide an electrical connection. 
• Bring your vehicle to our facility where we can use our Master Cable to flash your vehicle.

For reference this ECU is a Siemens MSD85.
