But a reasonable rule of thumb: If you add the currents for two coils together (or, the max theoretical current for the wire on the toyota OEM harness), then the wire that feeds them should be able to support that much current. I.E. if they are each 20 ga, I'm sure 18 is fine.

Hey folks, just wanted to thank everyone (lazzer408 in particular) for providing this information. I just did the COP conversion on my 1990 miata with success. However, one interesting question / observation. I have a little single blue LED made by VARAD installed in my center console (fake alarm). It begins blinking when the ignition is turned off. It has basic wiring - constant 12v, ground, and a lead to the ignition fuse. When it senses power on the ignition line, it turns the light off. After doing the COP conversion, when the car is running, the light doesn't turn off but rather goes dim and flickers quickly. Any idea's?
Once again, thanks for the awesome info.

After almost a year of perfect service with my COP system my car started to loose tach signal. After a while longer the car completely shut off while driving. Almost one week went by as I broke down different parts of the wires searching for the new found issues. I found the heat from the valve cover cooked the wires and 135c heat shrink. I copied SparkTechs use of varflex Mil-spec heat sleeve to protect the wiring. I hope this will help others using COP setups.

Emb ftl
One thing that worried me for awhile is the people who were failing to trigger the coils with their '99s. I read all around and it seems the one thing uniting them is the use of Greddy E-mangle Blue.
Maybe Brain could add to his archive summary that EMB doesn't seem able to trigger the coils when they are paired for wasted spark.
Crap! I just spent four hours reading this thread and related ones. Time to go breathe some smoky fresh outside air.

Well, This was a most interesting read... I managed to find a set of COPs on eBay for 53 bux shipped. spestis, if you see this post, I'm interested in your bracket. I don't have enough posts to PM you. For those with a 99-00 running the stock ECU, are there "still" issues with the COPs overheating? This is one of my DDs and the turbo and requisite electronics will be early '09 projects... Right now, I'm dealing with suspension and drive train stuff.

Concours C14 - does that mean they are a 1400 cc now?! Heh, cool.
As to the electronics, just build a MS. Get it over with. :-) Otherwise your car will become a stack of patches on top of each other.
There is no benefit at all to COP unless you're going to significantly over rev the car (not on stock ECU) or have significantly higher combustion chamber pressures (not without a turbo).
Finish your suspension, put in an MS, and keep those sweet-deal COPs until they will do you some good.

Hi I have a mazda mx3 with a b6t GTX engine with a b6de head almost the same as 1.6l miata i have bought Celica GT COP to do the COP things
But I Also have a MS2 witch im building right now and i don't find how to run the car FULL COP running it in Wasted Spark seems easy way but any solution tu run it in FULL. Need help thnx Ah And btw im French :P
Car is now running 323 BTX B6T Ecu at 7psi TD-05 Turbo 148WHP at 6000RPM
