    ENGINE RPM DISPARITY

    Just set up the instruments screen on my 12 Live. I have an interface cable, from the motor to the network. While running yesterday, the RPM of my 250SHO was about 300 RPM lower on the interface readout on my Live 12, than on the engine RPM gage. Which readout, does everyone think is correct?
