Comes with tach and driveshaft and will record volts and a 12V event. Meaning it will record a switch on or off basically. Go with your typical pressure and temp sensors. Oil and trans., fuel pressure to start. You can add a vac. sensor and O2's. The temp sensors are about $40-$50 cheaper than the pressure sensors. My pressure sensors have been spot on with my gauges. I don't have the O2's yet but have installed them on some dragsters I worked on. Got everything from Figspeed. You can run the Grid with a 7 series, not sure about a 6.
