Sensor on the P-lead of each slick.

I have a hartzell gov, and the arm swing is good. Everything from the outside looks like it should work. Everything is stock from Van's FWF or Lycoming.
I definitely pulled the plug on the crank case, that isn't the issue. I just don't know the first place to start looking.
The only thing I can see from the outside, is this spacer between the governor and the engine, maybe the teeth on the gear cannot reach far enough. See picture.

Perfect thank you.

With Dynon it is usually a wire to the p-lead with a resistor.

Agreed. The Dynon default is 1 for four cylinder engines. You need 1.5
for six cylinder. Not sure why you would be getting double actual if you
had the default 4 cyl setting. Make sure you have the approx 30K
resistor in the line between EMS and P-lead. Can need higher if there
are some spikes seen.

Not having studied the Dynon manuals, my guess would be that two pick-ups (one on each P-lead) are combining to double the reading.

I was thinking the same thing. If the setting is 1 and needs to be 1.5, then 2,000 rpm would read as 3,000. If it was set at .5, then it would be triple instead of double. Either way, it should be made correct by adjusting the pulses per revolution.
Also, in my instructions, I was assuming it was Skyview. The D120/D180/D10 would be different.
Give me a call tomorrow or the next time you are at he plane and I can walk you through the setup.

Make sure you have the 30k ohm resistor inline on both the white/green and white/blue wires close to where they tie to the p-lead, then follow this (6-cyl should be either 1.5 or 3.0 based on this):
Increment or decrement the PULS/REV R and L values to correspond to the number of pulses put out by your tachometer source for each engine revolution. You may select the pulses/rev for both the left and right tachometer inputs independently. If they are both p-lead inputs, these will likely be the same number. However, if you have connected two different types of tachometer sources, you will likely have to input different values into these fields. If you are using a p-lead connection, the PULS/REV value will typically be set to 1⁄2 or 1⁄4 of the number of cylinders in the engine. If you find that the onscreen tachometer reads double or half what you expect, adjust the PULS/REV value until you observe the expected value. If you do not have anything hooked to one of the tachometer inputs, the PULS/REV setting for this input can be set to any value. The FlightDEK-D180 will automatically ignore this unused input
