EFILive natively supports the RoadRunner. In order to use it with EFI Live, you must purchase the Roadrunner license. After purchasing the license, you can use the Roadrunner in any vehicle supported by the ECM. You can tune as many RoadRunner equipped ECMs as you like – you do not need to buy additional licenses for additional RoadRunners. If you want to flash a copy of the program in the Roadrunner into the vehicle’s original ECM, you can do this but standard EFI VIN or Stream licensing fees will apply.
