Hello all, I am updating my gauges on my PPC and I am trying to find some new instruments. I know that my 503 has a single pulse rate so my options of tachs seems limited. I currently have an old Westach analog that has seen better days. I would like find a newer colored analog tach like Aviasport or Skysports in either 2 1/4 or 3 1/8. Does anybody know of any that can work on a single pulse that my old rotax produces. I don't really care if the min/ max matches exactly. Most tachs for a 503 seem to only have a pulse rate matched for a ducati ignition which is either 2 0r 6 pulses per rev I think..
