Pulse widths & duty cycle

[nacelp]

For a single batch fire strategy, you have 10msec, at 6000 rpm.
Number of cylinders doesn't matter.

SEFI,Bank to bank and TBI are just different firing strategies.

The Duty Cycle is just time ON, compared to time available (for one entire
cycle)

   I'm sure I got it right now <g>.....
