The DataQuest system easily plots Clutch RPM and Clutch Slip Percentage.
One unique feature the DataQuest system has is that it does NOT require a sensor on the input shaft of the transmission. The system is smart enough to determine which gear you are in and then can accurately compute input shaft speed from drive shaft RPM. This reduces system cost and installation issues and provides EXACTLY the same data as having a sensor in a manually shifted car.
Yet the DataQuest does allow you to install a sensor when you may be running a lenco style transmission and want to be able to see the diffrence between clutch slip and transmission clutch slip.
