On one gauge it has 3 functions when you hit the mode button. mph, time, trip something? my question is the trip something? That is the 3rd function that I do not understand clearly. This gauge also has the gas level in the right side in a vertical stack column style. I was wondering if this might be the trip to empty ? is this yamaha's version of the flo-scan fuel computer or fuel flow managers? Anyone with any help would be appreciate. I also have the other gauge to go with this. Its a pair. this one has the rpm, oil level, temp alarm. I was wondering how it goes as well. I understand the rpm part. I see the oil levels and where it is indicating but I was wondering if it will flash red or yellow or green or anything if the oil is low or full or half way? thanks again.
