The CDI has 4 outputs, but the way its wired it can run 6 coils individually. The question you need answering, is whether the microtech can run the CDI? And conversely, if its actually a CDI you need as opposed to a spark amplifier like a 6AL MSD box?

6al is cdi. capacitive discharge ignition! the way it works, which some people are missing here is as follows in real basic terms. in a conventional system you have +12v (slightly more when alternator running) to charge the coil primary windings. in a coil, its basically a step-up transformer and the more voltage you feed to the primary winding the more you can get out of the secondary winding, because of the secondary winding having more turns then the primary. now with a cdi module, it takes the +12v battery voltage available and steps it up to around 400v and charges a capacitor in the module/box, when the ignition module/ecu fires it, the cdi sends it through the primary windings (400v) and you now have more voltage for firing the spark plugs available because of that increased primary voltage. now a capacitor discharges very quickly, so you get a short spark, but very powerful. in a conventional coil, you get the initial firing voltage, which is high up to 40k+ underload, then the remaining charge continues the sparking but at less voltage (takes more to initially fire then sustain the spark) the longer the spark the more complete burn you can get and better emissions and torque. but if you have a massive engine and cylinder pressure is really high, the conventional system, may not have the energy to initially fire the spark (missfire) but if you had a cdi because it has more primary voltage, it will be able to fire the plug, but the duration of spark is very short, but you take a short spark over no spark! because a capacitor can charge so fast and discharge so fast, most cdi will fire multiple sparks at low rpm, where there is time to do this in the engine cycle, kind of simulates a continuous spark from a conventional 12v ignition system.

thanks for the lesson buddy, good to actually understand whats going on, i've always struggled with ignition i never paid attention in electronics at school :P
