Iím curious if the AFS system can read in two tach readings, and if so how it handles/displays that data.

If only using one input, does it need to go to pin 32 or 33?
Iím not sure it matters, but I would do 32. Just remember that there is a left and right config on the EFIS. You just need to ensure you configure the correct pin.

I used both. It switches rpm reading to each mag when you do the mag check. If there is significant rpm difference, just another indicator that you may have difference.
