Tach Pickup with Starting Vibrator

[Douglas Geese]

I have an IO-470 with Bendix mags. I'm also installing a bendix starting vibrator on the P lead and Retard lead on the left mag only during starting (right mag will be off). I plan on picking up the tach signals via P lead tap with resistor (EMS pins 32/33). Are there any concerns with the effect the starting vibrator may have on the EMS input?

Update: Dynon tech support says the starting vibrator will have no effect upon the tach inputs. For anyone else interested.
