I think my Faira gauge must have reset at some point, but I do have a readout from the ECM - is there any way of manually bringing my hours up on the Faira gauge to match the ECM hours? Also, 3 of my Faria Commander gauges are not working - I may send them to Faria for repair, but if I replaced the whole set with the Chesapeake range, so that they're all the same, could I adjust the replacement hour gauge upwards to match the ECM?
