Igniter
Posted: Thu Nov 17, 2022 12:53 am
After some experimentation it seems the direct igt output from the ecu will drive internal igniter type coil on plug coils.
The issue of course is that there is just the one igt output.
My ecu has the facility to output igd (the same as a 4agze DLI) and the engine will run with coil on plug in wasted spark mode.
The problem is that the igd output has no dwell control and those two coils get very hot, quickly.
I know from Jondees posts that the igd output drives the 4agze igniter sequence.
I have tried driving the coil on plugs using the 4agze igniter but it doesn't work so l'm assuming the igniter is pulling to Ground to fire.
The igt output is +5v and fires the coils.
I wonder if dumb cops (☺) would work with a 4agze igniter?
