Thanks, got this working a while ago turned out to be an issue with scope I think, used an Arduino and was all good.

Just an update to the code above, appears that Arduino signal is inverted, So that is fixed, it's as close as you'l get to the real 18x 3x and REF Hi signal i think, i included a button to toggle rpm's, i have been cross referencing 3x and Ref Hi in car with a scope to this playing with dwell times on bench. Let me know if im wrong. :lol:
