Howdy. I have a TZT3 and replacing all my electronic gauges this year (tach, temp, engine pressure, transmission pressure, voltage). No plans to digitize those for Furuno readout, because I don't want to dedicate an MFD to digital gauge readouts... HOWEVER, I would really love to get performance data to determine my best running speeds. I assume that if I purchase a flow meter for my diesel engine (which means feed and return sensors) that sends the digital signal to N2K that my Furuno TZT3 can use that along with time and speed to show me performance numbers. Am I correct here?
