COP wasted

This means that amplified COP can't run Waste spark via Twin spark ?

Incorrect.

It means you can run two amplified coils on 1 output, which is the same as using twin spark and separate outputs.
If you have an S60, and want to run a V6 with COP, you can use the first 3 outputs with amplified coils.
The same applies to an S60 with a V8, using all 4 outputs.

You can't do that with dumb coils, as the ECU cannot charge two dumb coils properly from one driver.

regular inductive coils would be better wording.

But you could run multiple coils like an IGN1A off a single output if you wanted with "external amps" checked

But with the twin spark option...there isnt much reason to pair coils up to a single output ?

Thanks, I'll remember that.

As above, 6 and 8 cylinder engines on S60.

Associated query - corrected as required.
Average COP coil - non amp'd = 12 and 1 ohm resistance - if paired up in series, the circuit would be 12v and 2 ohm resistance (but each COP would see 6v @ 1 ohm?) and if parallel, the circuit would be 12v and 0.5 ohm (but each COP would see 12v @ 1 ohm?) I know this is fundamental electrical theory but never studied that at school half a lifetime ago !

Pretty much, except that coils aren't simple resistors, and current increases with time.
