Twin 2001 Yamaha Z200 HPDI install w/ Instrument package. The dealer that installed the system didn't connect it to the chartplotter as required for Fuel Mileage readout. I have connected it but... here's the problem: Stbd engine only it works fine but when the port engine is started the MPG indicator goes to 0.0 and doesn't move. If the Port is the only engine on, only it's tachometer works so you don't see the FM display.
