 RSTuner by Fastchip RSTuner is an easy to use software application, developed by Fastchip for use with its VCI hardware, specifically designed for diagnosing and recalibrating Renault RS series engines. RSTuner enables enthusiastic RS owners to reprogram their ECU with one of the calibration files from our database, stock or modified, and then log diagnostic data directly from the ECU through the diagnostic port.
Optionally a custom tailored engine calibration can be made to meet different engine setups and/or fuel quality. All the user has to do is, to provide the RSTuner generated data loggings and performance analysis. Reprogramming the ECU can be done as many times as required on the same vehicle.
