RSTuner software and VCI firmware are ready for Windows 10!

Latest Software

Make sure you use the latest versions of our software and firmware.

Trusted Performance

All our calibration maps are created in-house by our world-renowned (and often copied), SAE certified calibration engineer.

SAE CERTIFIED

Easy to Use

Our software is consumer oriented, not only for mechanics. We've worked with Renault's dealer software and improved on it. However, easy-to-use does not mean lacking in options or power.

Personal Support

We go to great lengths to support our valued customers. We've created custom software builds and updated calibrations on weekends to solve specific issues. We're here to help, but please read our FAQs and manuals before asking!

Easy Tuning.

Load a calibration and tune your car within minutes with just a few mouse clicks.

Easy Diagnostics.

Diagnose and fix your car without expensive trips to the dealer.

Programming Tutorial

One of our tutorial videos showing you how easy it is to program your own car with RSTuner. Programming your car can be done as often as you want at no extra cost!
