i dynoed my yellow jacket fri day nite bone stock except for muffler, air cleaner lid off , i dont think im ready to tell what it did but the results may have flawed due to erratic or innacurate tach signal our dyno jet prgram want to know how many times the leading coil fires per revvolution , any one? dyno is a dynojet 248 and the prograam is winset 7 , any help would be appreciated, thanks trevor

 

Set it up like a 4cyl I believe. Thats how you set up a tach on a rotary. It fires 2x per e-shaft revolution.

Did you do runs with the air cleaner lid on?

 

no but i will today for pur dee baseline
