Honda Direct Fire Coils

[Huw Scourfield]

Please don't take this the wrong way Chris, but you're a fool. If you are
unfortunate enough to have a serious "off" with that car you run the risk of
an electrical fire, all it would take is one little short circuit - up she
goes! Put some fuses in, even 20A fuses will protect most harness wire from
melting, yet be unlikely to blow due to surges/ ageing (depends on load of
course), you can get some pretty robust blade fuse carriers now that are
pretty much water tight and should be problem free. Think about this Chris,
it's your life, but fuses needn't be a problem if you position them well and
rate them generously.

All this talk of wasted spark coil packs got me thinking.  I am thinking of
trying to use Honda direct fire coils from an S2000 on my race car (Honda 4
cyl, 10,000 RPM)  They look like a long (6") spark plug boot (if anyone
hasn't seen them) and sit directly on the spark plug.  They also have a
built in ignitor.  The only terminals they have is +,-, trigger and of
course the connection to the plug.  No idea what kind of trigger input it is
looking for, the service manual has absolutely nothing.  I need to figure
out if I can fire this with a Haltech IG6.

Anybody have any info on these types of coils?  I would really like to be
able to use them as having no plug wires means there is four less cheap
parts that can break and end a race (same reason why you wont find a single
fuse in the car, and before someone asks, yes, that includes any computer
fuses)
