RSC's Range Rover 3.0L ECU Flash Tune will transform the driving experience of your Range Rover. Taking a powerful vehicle to the next level is our specialty.

An RSC Tuned Range Rover will optimize power output throughout the power-band enhancing everything from the morning commute to midnight drag races (in Mexico of course) With more low end torque and razor sharp throttle response, an RSC Rover dominates the competition. Combine that with our amazing customer service and you'll find a package that can't be beat. With this package you can expect massive gains between 65-75HP at the wheels and 40 lbs-ft of Torque.

The RSC tune is installed via the reliable and easy to use Dimsport MyGenius programming tool. The simple portable device makes installation a breeze in your location at a time of your convenience.

RSC Tuning Hand-Held ECU Flash for RR 3.0L SC

Please note that in late 2017 Range Rover changed the network communication protocol for the 3.0 & 5.0 engines to a Flexray system.  As a result for some 2017s, and all 2018+ models, we do not currently have a handheld tuning device that will work with your vehicle.  Instead, for these vehicles we offer the option of sending our tuning equipment (Laptop & Hardware) to you & we can remotely tune the vehicle for you at your home.  This process does not require anything other than an internet connection, a battery tender to maintain the battery, and someone to plug the hardware into the OBD port on the vehicle.  We will login to the computer and take care of the rest. 

For more information on this process or if you have any additional questions please message us using the messenger button on the website (bottom right corner) or email us at
