The BMW N20 engine is a 2.0-liter turbocharged inline-four engine that was first introduced in 2011. It is used in a range of BMW models, including the 328i, 428i, and X3, among others. It features an advanced direct injection system and a twin-scroll turbocharger, providing quick throttle response and strong low-end torque. The N20 engine is also equipped with BMW's Valvetronic variable valve lift technology, further improving its efficiency and performance. Despite its relatively small size, the BMW N20 engine is a formidable power plant, providing a thrilling driving experience without sacrificing fuel efficiency.


The ZF 8HP is an 8-speed Hydraulic system Planetary gear automatic transmission. It is still used in a wide range of high end car models including: Aston Martin, most BMW Serie, Audi, Rolls-Royce, Toyota Supra, and many more. The ZF 8HP was first introduced in 2009 and is a popular choice among car enthusiasts for its smooth and responsive shifting, excellent fuel efficiency, and reliable performance capabilities.


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.
