ECU & TCU Tuning File Supply - The Tuning File Service

We offer ECU tuning files through our trade brand ByteFLASH, allowing customers to value add their business by offering remapping to their customers.

By Utilising the ByteFLASH brand, customers are able to market themselves as ByteFLASH Installers, where ByteFLASH is a software product, enabling them to establish their own brand and reputation in their area. The ByteFLASH brand does not offer retail-based workshop tuning directly to customers, and only directs customers to their nearest ByteFLASH installer.

JR Tuning is committed to providing some of the highest quality ECU tuning files available in the market today. We support a wide range of clients who wish offer Engine ECU or Gearbox TCU remapping services to their clients. Our dealers range from traditional car performance and modification centres, through to tyre shops, car sales dealerships and other tuning companies who choose to lean on our support and experience to grow their own business and offer the very best to their clients.

We're not simply 'another generic ecu tuning file supplier'. We offer full technical training to those new to remapping along with ongoing support. Additionally all ecu tuning files are written in-house. We won't have any 1st line support engineers, the person on the end of the phone dealing with your support request is the person writing the file.

Already using another ECU tuning file supplier?
If you're moving from another ECU tuning file supplier and already have equipment you're comfortable using, more often than not we can migrate this equipment from your existing tuning company to our master.
