MS3X & MS3Pro - Tacho calibration

For people using MS3/MS3X and MS3Pro for EFI, you can calibrate your tachometer to read what Tuner Studio shows for your actual engine RPM's. I my case, my tachometer was reading a little high, so I adjusted it using the Tacho drop down menu:




Note that you will need to do a power reset once you select "variable". Then you can select a percentage that bring your tachometer in line with what TS is reporting for engine speed. I noted tachometer readings at various engine speeds rechecked the car tachometer after adjusting the tacho %.
