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

Re: COP wasted
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.

Re: COP wasted
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 ?

Re: COP wasted
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 !

Re: COP wasted
Pretty much, except that coils aren't simple resistors, and current increases with time.katana wrote:Associated query - corrected as required.
