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.

IMPORTANT NOTE: Installation of the ECU remap and back to stock can be done by any official Mosselman Dealer, or for most cars at home with the iMoss DIY solution that we offer (contact us to confirm the iMoss availability for your model).

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. Installation and back to stock can be done by any official Mosselman Dealer, or at home with the iMoss DIY solution that we offer.

The Stage 1 tuning will take your BMW 525d G30/G31 to approximately 260 hp and 550 Nm.

BMW 525d G30/G31 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.

MOSSELMAN tuning experiences

My first impressions after the remap: the acceleration is much more dynamic, it feels like the car now has the powertrain that fits it well! I’m very satisfied with your service, explanations, and friendly approach. Thank you!

Dennis - BMW X5 40e
Mosselman tuned my BMW 318d today. What a result, it became a completely different car! Very professional company and friendly staff. This was my second car here and again they have exceeded my expectations. Thanks!

Thom H.
Very happy with my improved car, the car reacts better on the throttle and is very direct. Also, the exhaust sounds better!

Rob M.
With Mosselmans' performance package I exceeded even more than the company advertised on their website! The information-sharing process was easy and hassle-free. Excellent customer service from Leon and his team!

Anders M.
After 1,5 years still very happy with my iTronic. By far the best upgrade I could have done with my BMW 340i.

The iTronic is an advanced engine controller that works simultaneously with the original ECU and is highly recommended on new and young BMW models that still have the factory warranty. It is designed as an external module (tuning box) that can be installed and removed by the end-user, minimizing problems with the factory warranty.

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.
