This has been rumored to work, but I wanted to see for myself.

So I finally got the coils I wanted to use for this test. A set of 01 civic coils.

I made up a little harness with the coil plugs. Tied in the 12v and ground to each of the plugs, and tied all the coil signal wires together and hooked them up to my IGT igniter output.

It worked!!!! I was able to run distributorless without a special module. Somehow, firing all 4 coils at once does not ignite the intake charge at the bottom of the intake stroke.

I had tested this same concept out with a set of camry coils. These were the non-igniter type, basically a coil on plug controlled by a seperate igniter. Using these, I backfired out the intake every time. The car wouldn't run. I'm guessing the honda coils are more precise and have a shorter duration spark which misses setting off the intake charge. That or the spark is only strong enough to set off a compressed A/F mixture?

This is an awesome discovery, though not one I originally made. For some reason, it's been around, just nobody has really brought it up amazingly.

So, aside from the potential intake backfire, I can't find any other downside to this. Like I said, most likely I will be integrating this feature into my harness for a small additional cost. So when you buy my harness, you can avoid bashing firewalls or spending money on dizzy relocation kits.

The thing is...this would probably work on other toyotas.
