I recently installed a MyChron 5 on my Rotax 125 Max powered kart and I’m not sure I have the tach / rpm settings set up properly. After a day of testing, I was reviewing data from my laps and found my min/max rpms as 8000/15900. This is well above what the Rotax should spin to, but power and performance were enough that those being double the actual rpm value doesn’t make sense either. I cannot find any information about setting up the rpm factoring in MyChron. Anybody run a MC5 on a Rotax kart who can help?
RPM frequency: 20hz
RPM factor: x2
Max Speed: 57mph
Track type: short road course, < 30 sec lap time
