New driver added to ignition in place of XOR gate. 100k resistors from JP7/JP8 to ground. <That fixed noise issue with load jumper in place that was creating spark at plugs.

Proper ignition signal attained using stock Miata (Mitsu 4+2) CAS.

I did all of my Jag bench sorting in a Win 7 VM on a Mac OS desktop running EMSTune/studio with JimStim and factory Mx5/Miata harness/connector.

Got my CAS offset dialed in using Fred's patented "shoot, shoot again" method changing the hex in EMStudio/tune.
