By the way, Honda CBR coil packs are pretty much a drop-in on most Honda engines if I remember correctly, but you have to make sure (as with any cycle coilpacks) that you don't get ones that are for capacitive discharge (CDI) ignitions because they won't work with the majority of ECUs.

Also, you can't use a stock ECU with coilpacks, because the stock ECUs only have one ignition trigger output (that's what the distributor is obviously for). Megasquirt only has two ignition outputs, so it can only do wasted spark, not sequential ignition. You'll need a coil driver module also, unless you get an aftermarket fully assembled Megasquirt unit (which may have the two coil drivers built in, but I don't remember).

So make sure you buy an ECU with individual coil outputs, (and maybe an ignition driver module, depending on the ECU) to go along with your coilpacks.

You're right though, there really isn't any advantage with coilpacks except that there aren't any plug wires to wear out and the EMI radiation is lower.
