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.
Once the engine has been warmed up, connect the VCM to the
motorcycle’s Deutz connector and go for your data logging ride. The memory will record 15 minutes of data.
