- Tournament 275
I have a 2009 275 Tournament, I replaced the square Tach gauges(2) with another set of the same with better screens. They power up but do not show any data. When I put an old one back in there is data. I am thinking there is some sort of pairing that has to happen between the new gauge and ECM. Does that sound valid? I see in the instruction guide where you set the engine number in the gauge but I thought it was just basically a display of ECM data. Any ideas would be appreciated. the gauge model is 6y8t.
