    The RSTuner kit allows you to unlock your Renault's hidden power.

    Simply plug the interface in between your laptop and your car's OBD diagnostics port, and within minutes you can upload one of our performance maps to give you additional engine horsepower. No cutting, wiring, or other such modifications, simply plug-and-play and enjoy the unlocked performance.


    Fastchip Stage1 map is included with every purchase that will give instant performance gains between 1-40 Horsepower (depending on the car type) , over stock levels.
    Our included Stage 1 map will NOT lock your ECU ! Unless you request us to do so (to prevent dealer overwriting for instance)


    Also gives you the ability to easily change maps as you upgrade to new parts for your car. All possible with a few mouse clicks with the RSTuner kit!

    Our staged maps are developed in house and tested on a Dynojet single roller rolling road, to guarantee top quality.

    User Requirements

    • Familiarity with standard Windows based software applications. [PC/laptop needed]
    • RSTuner is provided on the understanding that the user appreciates and understands the responsibilities in regards to reprogramming the ECU.
    • User must have a good knowledge of the English language as the software comes in an English version only !


    RSTuner Pro

    Our Pro model accepts up to 4 external sensors (0-5 V) such as Wide Band sensors, right into our auto-scaling Live Data datalogger. You will have real time data from those sensors integrated with your standard engine ECU Sensor Data for easier understanding.


    RSTuner Premium

    The Premium model comes with a built-in 'Flight Data Recorder' which can record many hours of engine live data without the use of a laptop, simply by pressing the control button. During trackdays all data can be recorded and later reviewed at home from your PC. External trigger port can be set to every available live data parameter. This way it can be set up to be a shift light, knock warning light or an IC waterspray trigger. Or anything else that you find useful.

    I used the RStuner VCI to update my stock ecu cal. file on my (53) RS Clio with the stage 1 (98ron) cal. file. The update took only a few minutes & my car has been totally transformed... It now seems to have more power & more torque, especially in the low to mid rev range. ? In addition to this it now also handles corners far better than it ever did before, the increase in torque totally eliminates any oversteer issues & causes the car to understeer more which in my opinion is easier to manage. ? Awesome, ? % recommend. BillyClio, UK. ??
