Hello, I realize this is an old thread but my question pertains to rpm settings for a 37HP EFI Vanguard on a new Ferris IS3200Z. I installed a Trail Tech panel mount tachometer and need to know the proper setting for the tachometer setup. The “Pulse Per Revolution” setting must be programmed during the initial setup. The possible settings are: 0.5, 1.0, 2.0, 4.0. Can someone please tell me the correct setting for the setup of this 2 cylinder, 4cycle application. I assumed the WOT was properly set to 3600 RPM by the dealer during initial setup so I set the throttle to wide open and tried each PPR setting, expecting one of them to show 3600 RPM but none were close. I’m not sure which PPR setting is correct since the WOT seems to be off. Thanks in advance for any assistance provided.
