BMW F90 M5 ECU Flash

Mase Engineering

With the Mase Flash for the BMW F90 M5, you can unlock the full potential of one of BMW's best engines. On top of an incredible 100+ HP and TQ gain, we rework the throttle maps to improve the cars throttle response. With our tune, the car will feel completely different and is guaranteed to improve in almost every aspect.


We offer two options for flashing your BMW F90 M5: 

  • The base flash involves the purchaser sending your ECU(s) to us and we will flash your new tune and typically have the ECU(s) sent back within 48 hours.
  • Option two is a flash using the Mase Flash Programmer. For an additional charge, we send you the Programmer preloaded with your new tune. To load the tune onto your car, you simply must plug the Programmer into the OBD2 port and follow the provided instructions. One benefit of the Programmer is that it allows you to switch between your new tune and the stock tune at any time.

 

The BMW F90 M5 ECU Flash requires the ECU to be shipped to our facility. In most cases, we can turn around and ship it back same day to minimize downtime.  We include a guide on how to safely remove the ECU for shipment.
