ive got a revo select serial port switch lets change the settings on your revo remap,
The 'select' gives the user the ability to switch between stock and performance mode. This performance mode can be set by your Revo Technik dealer to suit your car, fuel quality and climatic conditions. Additionally the 'select' features an Anti theft function which is designed to disable the ECU itself
