Expert's advice:

Developing the best possible ECU remap (chiptuning) for a car requires time and intimate knowledge of the vehicle you’re tuning. In order to provide high quality ECU remaps, our mappings are developed exclusively for BMW and MINI cars. Before we add an ECU remap to our line-up, we make sure it’s tested thoroughly on our dyno. Our software is engineered to create a smooth power delivery that keeps going till the redline, without putting your engine at risk. Besides that our Stage 2 and Stage 3 software are designed to get the most out of our Mosselman high-end performance parts.

Please note that an ECU remap will void the factory warranty once detected by a BMW dealer.

With an ECU remap, also known as “chip tuning” or “reflash”, the original ECU of the car will be recalibrated on several different engine parameters for more performance. Options like speed limiter removal and start/stop deactivation are available. Please note that an ECU remap will void the factory warranty once detected by a BMW dealer.

The ECU Remap will take your BMW 420i Gran Coupe G26 to approximately 260 hp and 410 Nm on premium fuel (98 Oct EU / 93 Oct USA), which is highly recommended.

BMW 420i Gran Coupe G26 TUNING.

Tuning a car is a delicate thing. Whether it’s an ECU remap, a new turbo or a full-on stage three tuning, you need to make sure each component is working at optimal efficiency under careful supervision of a sufficiently smart engine management system. After all, you’re looking to create a symphony and that’s hard to do when one of the instruments is off. That’s why all of our products are designed and built in-house. Professional tuning requires a steady hand and we want to be solely responsible for getting the most out of your car.

Because most modern engines are heavily restricted due to emission regulations, an ECU remap is always the first step towards unlocking the performance your BMW is capable of. However, as our name implies, we do have upgraded turbos, should you be in the market for one. In addition, Mosselman Turbo Systems offers more efficient intake and exhaust systems, oil thermostats, oil coolers, and intercoolers. So if you’re looking for more performance, you’ve come to the right place.
