MK 5 GTI
MRC’s ECU upgrade for the MK 5 GTI is available globally in octane-specific variations. Locally 95 octane is the choice of fuel in South Africa. Each car is individually tuned on the in-house 4WD dynamometer. The process of flashing the ECU is conveniently done to the vehicle’s factory ECU through the OBD-II port without any physical modification to the factory ECU.
All of MRC’s maps are completely custom-created at the head office. Correspondence is done via email and logging while the car is on our 2WD/4WD dynamometer. This obviously comes at a slightly higher price; you get what you pay for!
MRC specialises in VW, Audi, Petrol and Diesel models, and has an extensive knowledge of the software and hardware modifications necessary to get the maximum reliable power out of the vehicle. This also means we can be certain all your hardware is functioning correctly before starting to tune. General checks are done before tuning commences.
