Engine tuning (DME/ECU/ECM Tuning) for the BMW F90 M5 typically involves modifying the engine management software, also known as "flashing" the ECU. This process can increase horsepower and torque, improve throttle response, and also change the shift points of the transmission. Some popular engine tuning options include: Software remaps: A remap of the engine management software can increase the power output of the engine by adjusting the fuel and ignition maps. This can result in significant gains in horsepower and torque. Downpipes and catless exhaust systems: These modifications can improve exhaust flow and reduce backpressure, which can result in additional horsepower and torque gains. They also give the car a more sporty exhaust note. Cold air intake systems: Replacing the factory air intake with a high-flow aftermarket system can increase the amount of air that the engine can take in, resulting in more power. Intercoolers: Upgrading the intercooler can help to reduce the temperature of the incoming air charge, which can result in more power and improved consistency. It is important to note that any engine modifications should be done by a professional and it's also important to make sure that the tuning is done correctly as it can cause damage to the engine if not done correctly. Additionally, some modifications may void the factory warranty, so it is always important to consult with a professional before making any changes to the vehicle.
