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 320i, it is necessary to modify the MEVD17, either through remapping or through the use of an aftermarket tuning box.
 
There are several reasons why you might consider BMW N20 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.
