Exhaust gas power valve sensor provides a very accurate indication of the exhaust gas valve working, measuring its gap in millimetres. The sensor, which measures valve stroke up to 20 millimetres, samples the RPM value that opens/closes the valve and all intermediate values as well. Data is immediately visible on the MyChron display: the RPM/Gas Valve graph of the analysed lap appears. With the Race Studio Analysis software, data from different laps can be compared on your PC. The closed valve position is auto-calibrated by the sensor. The sensor is currently compatible with Rotax-type valves, used by the following engines: Rotax, Super Rok, Maxter, Maranello, Iame, TM. Compatibility will shortly be extended to other valve types. The Exhaust Gas Power Valve Sensor can be connected to the MyChron Expansion via specific adapter cables. It includes an extension cable in the box.
