Your VCM is now ready to log data while you ride. The engine should already be warmed up before you go for the data logging ride. It can hold a maximum of 15 minutes of data. NOTE: If the engine is not warmed up, during the warm up stage

disconnect the VCM from the motorcycle’s Deutz connector. You don’t want this data to be logged.
