High RPM reading with Lightspeed

[flyingboy]

This maybe a Lightspeed question, however I have duel electronic ignition system, just started my engine and have the RPM reading high on both my Skyview panels. It looks like it is reading double what it should be. Anyone out there had this issue or can assist would be greatly appreciated.

Cheers

Hugh

What is the PPR (Pulse per revolution ) set at ? it should be 2 for a 320 or 360 Lyc however it's usually 1/2 to 1/4 the number of cylinders - try changing the value, it won't hurt anything, you'll know when it feels/sounds right
