Testing coils on a coil over plug system?

Art, not sure I would spend any time looking at Crank or cam triggers, as they would just make the engine quit no matter what. Did you get your spark checker if so do you have nice blue spark from all coils? I asked before about MAP sensor... what does it read? Do you have any tuning tables that use the MAP input to change fuel or timing perhaps coil on time based on MAP or fuel enrichment based on MAP sensor? Can you "see" in real time what timing and pulse width is being commanded by the ECU?Also can you view your Crank sensor count in real time, sometimes referred to as Wheel dbug counts?
