We just starting using it. We like it. Still learning how it all works. It has helped us alot with the stick car. We download the runs to the tachfacts software that comes with it. It then graphs the runs showing you engine and driveline rpm. It helps with showing shift points and how far it pulls the motor down on gear changes. It also shows you if your shifting late(computers don't lie). We still need to add the clutch sensor. The tach was easy to install. I bought the collar and magnet kit from Mark Williams. It's easy to install on yoke. Make sure you only install 2 magnets in the collar. It put all four and couldn't get and readings. I talked to a rep at the nationals in Dallas and he told me it won't work with 4 magnets. Tach also plays back runs on the tach itself. Press a few buttons and you can play your run back instantly. Hope some of this helps. Ed
