GM ignition - try #2

Hooked the lab scope up and found the s/w is firing the coils advanced and missing 1 firing pulse.... Sent Mr. Software guru a few pictures of the scope display... waiting for a code update.. I figure it'll take another 2-3 s/w mod's to get this sorted... This is really raw development work and Sh*t just happens.
