Chip-Racing was founded back in 2003 and was soon known for quality ECU-tuning! Roman Ritzmann has started in 2000 with ECU programming. He tuned mostly german cars like Audi, BMW and VW then. Since 2005 our headquarter is located in Pfäffikon ZH, Switzerland.


We are known, and intend to continue to be known, for professional car-service and repairs of all kind of cars, as well as the professional tuning!

We’re specialized on japanese cars such as Subaru, Mitsubishi, Nissan, Honda, Toyota and Mazda. Of course we also do have a wide range of parts for non-japanese cars like Audi, Ford and BMW, feel free to contact us!

Of course Chip-Racing offers you, other than tuning, very interesting solutions for alternative fuel systems such as E85 Bioethanol or just simply retune your cars ECU to lower fuel consumption. We offer a wide variation from standard files from full individual Dynotunes for street use or professional racing!
