4agze timing

[jondee86]

You may have a problem This is what I think, and remember that this is
just what I make up from what I know about the GZE ignition system.

The GZE ECU sends two signals to the GZE... one tells the igniter to trigger,
and the other tells the igniter which coil to fire. The signals from the ECU to
the igniter will be low level (ca 5V) and the igniter will then switch 12V to
ground to fire the coil. This system will work with any "dumb" set of two
double ended wasted spark coils. The igniter will generate an IGf signal for
the ECU.

Now you want to drive smart COP's (built-in igniters) wired in pairs to run
as wasted spark. These COP's expect a low level signal to tell the built-in
igniter to trigger. But your GZE igniter can only switch 12V to ground. This
will not work. The low level signal from the ECU to the GZE igniter *might*
be able to trigger your COP's, but since it will deliver 4 triggers for every
720 crank degrees, you could only use the signal for batch firing. And you
would need to take one IGf signal back to the ECU.

The only way to make your system work the way you want is to change to
dumb 2-wire COP's. These can be wired up in pairs to run wasted spark
with the GZE igniter switching 12V to ground to fire them. IGf is supplied
by the igniter as before.
