RedTop BEAMS COPs Wires

[puretone]

guys what the hell are those 2 extra wires for?!
I get the ground and the 12v (+) but why the hell are those 2 other ones required? Does our ECU need to know it gets fired & confirmed too?
It's the IGT/ION wires that run as the middle two wires on our COPs....I don't get it, everyone and their mom uses just 2 wire COPs, why so special with 4?

The igt is the trigger from the ecu to the coil, and ion is the confirmation.

The difference is that out cops contain their own separate igniters. The 2 wire cops you speak of are just coils. They are driven and controled by a separate ignition module.

I like the coil/igniter cops much better.

Bureaucratic god damn coil on plugs what the hell

But so how do these Honda CBR COPs work then, we have them install on a highly modded B18/19 engine, driven by VEMS, all 4 COPs have GND & 12v (+) and the ECU just triggers the bugger no separate ignition module to be spoken of.....I guess this ECU just triggers them by grounding the GND wire at the ECU end?

Sounds like with those, the igniter mechanism is in the ecu. Can't think of any other car with a setup like that, but I know megasquirts have an option for directly driven coils.
