If you go with COP, you'll probably want to use one of the many coil configurations that have the power transistor built into them, (three wire coils) and control them directly with your AEM. MSD systems use capacitive discharge and mutiple spark discharge. That system would obviously be inserted into the power feed to the coils.Īn HKS DLI on the other hand, is hooked to the control side, and uses capacitive discharge (among other electronic trickery they don't fully disclose) to increase the spark duration and intensity. Something like a Kenne Bell boost-a-spark increases the voltage to the coils in order to increase output voltage. You may be getting confused by the different styles of igintion amplifiers,boosters, and CDI systems out there. People have turned that up to around 90% and gained some performance, but the jury is still out on how it affects component life. That's done as a compromise to achieve both decent performance and long component life. The factory ECU programing sets the coil saturation time at aprox 75% of max dwell time. Of course I'm not sure what "too hot" might be.
I'm thinking now I'd better watch the temperatures of the coil housings somehow (thermo couple?) so I can tell if they are getting too hot from overuse. That would give me the maximum amount of charge that can be held in the primary coil. My first thought was increase dwell to the point where the knee is on the current charging into the primary coil. Unfortunately, on my EMS setup there is no controls for "dwell vs. However, isn't it better to be on the side of too much spark than on the edge of not firing because there isn't enough kV to bridge the gap? I would think you'd want to maximize it so that during WOT so you can run as much boost as you want and not have to worry about blow-out. I get what you're saying about maximizing output, you don't need more than one match to start a fire. There are 2 dimensional dwell maps for controlling "dwell vs. The EMS already controls the wasted spark setup and seems pretty easy to get it converted to sequential through options in the software.
Click to expand.It has six independent coil outputs and one gent has already made the conversion, so I know it's possible to do.
