Hello Rx7club!

I am currently going through my prestart checks for a na to turbo conversion w/ ms1 and jbperf vr board.

I have good rpm signal and spark on the leading coils but nothing on trailing at crank. Is this normal?

Ill be testing the coil and double checking the wiring but thought I would ask here in hopes of a quick yes/no answer

Thanks, Sam

Some coding limitation or bug in MS1. Trailing ignition comes on above 800 rpm or something like that.

thats normal.

Thanks!

Got the car running shortly after this post and saw the trailing spark come on line. It isnt working quite right but the wires and coils are questionable. mostly just one coil firing away, but thats not always the case.
