Discover the best additional control units for BMW engines. Many years ago, we began developing additional control units for BMW engines starting with the historic VP37 microprocessor for the management of electronically controlled rotary injection pumps for the legendary 6-cylinder 525tds and 325tds (and also for the less popular 318tds with 90hp 4-cylinder derived from the 6-cylinder with the same type of injection). Since then, we have developed additional electronic control units for BMW engines with radial piston injection pumps (VP44, mounted on the16 valve 2-liter with 136hp) and then for the more modern 4 and 6-cylinder common rail engines (and also for the 3-cylinder recent models). With the experience we have gained, we are now able to offer the best technology for increasing the performance of petrol and diesel BMWs, with high-performance microprocessor chip tuning units able to simultaneously manage the common rail system and the pressure of the turbocharger. The many internal digital maps and various digital adjustments allow very high increases in power and torque with maximum reliability for BMW engines. In some models, the increase can even exceed 50hp with remarkable performance! The thousands of kits sold for gasoline and diesel BMWs, the hundreds of kits sold to improve engine response, and the hundreds of positive reviews act as a confirmation of the quality of our chip tuning units over the years. Choosing our chip tuning units means choosing a quick installation using the original connectors, with no changes to be made, an immediate increase in power and torque, and a product that is 100% made in Italy. The best additional chip tuning units for increasing the power of your petrol or diesel BMW can be bought from SELETRON.

Additionally, you can also install our PEDALBOOSTER® without making any modifications. What is it? PEDALBOOSTER® is the additional control unit for the accelerator pedal developed to improve acceleration and eliminate the throttle valve delay, incredibly increasing driving pleasure. The performance tuning module connects in a few minutes directly to the electronic accelerator pedal via the original connectors, making your car feel extremely responsive while you’re at the wheel. PEDALBOOSTER® is available for both petrol cars and turbodiesel! If you want to increase the performance of your BMW, search for your specific model and have a look at our kits for increased power, torque, and engine response.
