BMW M4 Competition G82 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 or installation of an engine control unit is always the first step towards unlocking the performance your BMW or Mini 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.

Do you have a question?

Please take a look at our FAQ for the most commonly-asked questions, or feel free to contact us.

The iTronic connects with a couple of sensors from the car, including the mass airflow sensor and CAN connection. This allows us to read a lot of data of the car. For example, RPM, temperatures, and pedal position. Due to the CAN connection you can also turn the iTronic ON/OFF with the BC button on your steering wheel.

Most of the power boxes doesn’t have a good name in the tuning industry, usually because they don’t deliver what is promised. However there is a difference between tuning with a power box and our iTronic. The iTronic connects with more sensors than a regular power box, like the mass airflow sensor and the CAN-BUS connection. Thanks to these connections additional data, such as the throttle position, is available. We use this information to optimize the car’s software and increase the performance in a safe way.

The iTronic is plug-and-play and requires no modifications to get it installed. We provide an installation manual when you purchase an iTronic, the installation time is approximately 1 hour. Installation can also be done at one of our dealers, they will charge an installation fee though.

The iTronic is specifically developed for cars that still have their warranty. It leaves no traces in the software of the car, and because it’s an external device it can be removed, minimizing problems with the factory warranty.

No, we don’t offer any warranty on the engine after buying our iTronic. We don’t do this because we don’t know in what condition your engine is before you install the iTronic. However, we designed the iTronic to be harmless to the car and its engine. We do offer great aftersales services to our customers. If you have any problems with the iTronic we will do our best to offer all the help needed to solve the problems.

The iTronic comes with a 1-year warranty on the components and the software, under normal use during the warranty period.

The iTronic, and its wiring harness, are specific for each car model. The iTronic can be installed on another car with the same model and engine, but it cannot be installed on different models.
