I must have gotten a different coilset. On mine, there's about 3/8" space betwixt coil and valve cover when fully seated. On a 1.6 engine.

Post a pic of your coils, the part numbers, and the instalation. Sean has a 1.6 and the coils I recomended and ordered fit fine on both the 1.6 and 1.8.

Joining this discussion. Great idea here. I tried the Chrysler/AEM TwinFire amplifier COP system once. Worked okay until the AEM box fried itself. Took it off and run OEM coils again. This COP idea seems to be much less maintenance and in keeping with the KISS theory.

Only thing is I don't want to cut into the factory ignition harness again after the last debacle. I noticed an image of a connector on a previous page. That looks like it may fit the OEM coil connectors going to the 1.8l coils on my engine. I'd really like to find a connector that I could PnP with so I don't have to cut the 1.8l ignition harness again.

I already bought a set of 1ZZ coils off ebay. Just want to find a connector for the OEM ignition coil connectors before jumping on this project.

Just finished my PnP harness for mine. Still wish I had the toyta cop connectors... but i made do.





I'll test it all out, once I figure how I want to mount it.

Looks good. To bad I can't just disassemble an ignitor to do that for my '99.

How did you make the bit that plugs into the miata ecu harness? Also, how come yours is only one plug instead of a pair of plugs?

It looks like a gutted ignitor with the wires coing out of teh back from a hole.

Looks like it will be neat.

Congrats.

Now if only it worked 100% . I got car up on them first try, idle smooth, didn't test beyond that.

But... no tach. I have all 4 tach outputs merging and then merged with the 2 center wires on the ignitor....

I"m so close.

I'm trying to come up with a less permanent way. My GTX valve cover is in good condition... and I don't really want to refinish it.

Will the plugs not just sit on the spark plugs? Or do they not clip onto the plug like most plug wires do?

no they'll come off when you're driving. they fit on the plugs, but not as snugly as plug wires do.

dave, I find your tach issue odd. I'm planning on isolating all the tach outs from each other with diodes. perhaps that's an issue.
