Superchips, ECU remapping for petrol and diesel engines

Superchips is a British company specialising in remapping electronic control units (ECUs) for petrol and diesel engines. The firm presents itself as a pioneer in the sector and claims over thirty years of experience in this activity. Its offering is aimed at drivers looking to improve the performance, throttle response and fuel economy of their vehicles.

The company operates under the corporate name SGL Holdings Ltd, incorporated in England and Wales with registration number 16137497. Superchips is a trading brand of that company.

Remapping and cleaning services

The service catalogue includes ECU remapping, carbon cleaning and diesel particulate filter (DPF) cleaning. The company also sells its own tuning devices, including a range of tuning devices offered at launch prices and which will be available to purchase online soon.

Among the advertised products are throttle enhancement devices and performance modules. The company describes a throttle device that requires no map, does not compromise warranties and increases throttle response by up to 10%, with three driving modes: Race, City and Eco. This product works on petrol, diesel, hybrid or electric cars, is controlled from a mobile app and is fitted to the throttle.

The second device, a performance module, offers plug and play installation, TUV certification, three driving modes (Race, City and Eco) with seven fine-tuning levels each, and up to 30% more performance and torque. The company states that it is not detectable by main dealers, allows fuel savings in Eco mode, is reusable on future vehicles and is not lost after software updates nor affects the warranty.
