Don't expect mirracles from an COP conversion. I have had them all. Stock, stock with EMS, wasted spark and COP with Yamaha R6 coils. And I have run these coppers with the Autronic 500R which is having an "strong spark" function.
Well, I noticed nothing.
So, unless you are seeing really big horsepowers or ignition problems, nothing to gain here.
At the moment I run an stock ignition due to starting problems.
Once upon a time, the car did suffer good cold starts in the morning and I suspected malfunction in the ignition system somewhere. So I build her back to stock.
Problem started in 2012 and was solved in 2015. Problem was the reluctor interface, needed for the Autronic to work with the 3S triggering.
Anyway, now I still have my stock ignition because it is rock solid. Parts are easy and plugs lasts very long. And to be honest, I recently tested the car and she is the fastest ever in my possession.
My car is an ST85 and is seeing about 300 hp now.
