[Gmecm] More Northstar with 7730

[William Lucke]

I have discussed with the individual with whom I'm working on this project, 
and he seems to be measuring everything correctly, and the measurements 
still say that the reference from the ICM to the ECM is 33% duty cycle. I 
believe that this prevents the $A1 (V6 DIS) mask we had been using from 
calculating timing correctly (@$$uming that it calculates timing based on 
every transition of the waveform... is this a valid assumption?)
 From what I've been told by WOT, the 4 cylinder DIS reference is 66% DC... 
which is just 33% DC inverted... If I built a simple invertor circuit for 
the reference, which 4 cylinder DIS mask would be a good place to start for 
running a Northstar with 7730 or equivalent? Does the Q4 use a conventional 
coil pack?
