I know this question is not necessarily "rotary" but perhaps there are some
   Out there using Tracy Crooks EC2.  ( I use one on my trike with a Suzuki 4 cyl).

   I tap off an injector drive to get my rpm signal. Unfortunately my glass panel
   does not seem to accept 1 pulse for ever other revolution.  I was thinking that
   If it was sequential I could use two drives to double the pulses. If they all
   fire at once this would not work.

   Tracy was not forthcoming with those details but my guess it was batch.
   Mine is not running right at the moment as I am switching the RV4 to a carb.

   USB O-scopes are pretty cheap these days. Check ebay.

   Let us know what you find out.

   When I was discussing this with Tracy, he told me that all injectors fired simultaneously not in sequence.

Sounds like batch.
