N55
The BMW N55 engine is a potential tuning platfrom from which it is possible to extract even more power and torque compared to stock. The potential of a car depends very much on the components used, but the use of an MHD Flasher is a necessity.The potential of a car depends very much on the components used. With the help of MHD Flasher, adjustments can be made remotely based on the datalogs taken by the customer. The MHD allows you to change maps while driving with the steering wheel buttons (F-series). At the same time, a flex fuel tune can be made if only the necessary components are installed such as an ethanol sensor. MHD also offers an antilag feature.
With the stock components, power levels of + 400hp can be achieved, especially if ethanol is mixed with gasoline. With a hybrid turbocharger, the power class rises to + 500hp. Fuel flow is fast becoming a bottleneck in these engines and the most important change is to upgrade low pressure and high pressure pumps to larger ones. The injectors also need to be changed to bigger ones when going well over 600hp and ethanol is in use. We also do calibrations to the M5 EU5 injectors, which give more headroom for increased power requirements.
