Changing the rev limiter
Carmo electronics is able to change the rev limiter from almost every ignition and/or injection unit (CDI/TCI/ECU) to a desired value, higher or lower. Mostly a 500 to 1000 rpm increase is possible without mechanical damage to the engine. If you want more revs then it is wise to modify the engine.
Do you want to change the rev limiter from your vehicle (direstrict)? Sending your control unit (CDI/TCI/ECU) is sufficient. Click here for our address.
