The BMW S55 engine is a 3.0-liter twin-turbocharged inline-six engine that was first introduced in 2014. This engine is used in various BMW models, including the M3, M4, and M2 Competition. The S55 engine features a high-pressure fuel injection system and a dual-scroll turbocharger. The engine's advanced engineering, including its closed-deck block and lightweight construction, contributes to its excellent performance and fuel efficiency. The S55 engine also features an electronically controlled wastegate, improving boost control and throttle response. With its combination of power, efficiency, and advanced features, the S55 engine has earned a reputation as one of the most impressive engines produced by BMW, making it a popular choice among car enthusiasts who demand high-performance engines.
 
The MEVD17 is an engine control unit (ECU), also known as DME/ECM/DDE. It is responsible for controlling the fuel injection, turbocharging, and other engine management functions. In order to tune the BMW M4, it is necessary to modify the MEVD17 map, through ECU programming, remapping or through the use of an aftermarket tuning box.
 
There are several reasons why you might consider BMW M4 tuning, including:
 
- Increase Horsepower & Torque: The most noticable benefits of tuning your ECU is the increase in horsepower and torque. Even without aftermarket modifications, you can see a significant improvement in your engine's performance, resulting in faster acceleration and a more engaging driving experience.
 
- Improve Fuel Efficiency: While more HP and TQ is often the primary goal of tuning, many tuning parameters can also result in improved fuel efficiency. By optimizing the engine's performance, you can reduce the amount of fuel needed to accelerate and cruise, saving you money at the pump.
 
- Enhanced Reliability: By addressing common issues from the factory and making the engine more efficient, you can reduce the risk of breakdowns and extend the life of your vehicle.
