Never having to worry about plug wires again. Less emf interfering with other sensors. Props from your friends for pimping your own ride. :bigtu:

I was wondering the same thing...

If it can fire the oem coils it can fire these as wasted spark. I tried them that way before going sequential just to see if it would work.

did it work with your ems?

Yes. It'll work with the stock ECU or any other ECU that can fire the Miata coils. You will need a "higher-end" engine management system if you want to run them sequential. Otherwise you can fire them 2 at a time. 1&4 and 2&3 together.

as far as i can see there's only 3 wires into the coils packs on my 00, is there +something i'm missing, i cant seem to find the v+, maybe i should lay off the vodka before attempting wiring

i guess i'm going to have to find my own voltage source

I thought the newer Miata coils don't have tach outputs. The tach signal comes from the ECU or something like that. But I could be mistaken.

Yes, you're missing the wiring diagram :D http://www.madracki.com/miata/wiring.html

Black/White is your +12 supply. Brown/Yellow is coil 1, Brown is coil 2. The schematic shows a fourth (Black) wire providing primary ground, however I believe this ground point is local to the coilpack itself- no corresponding wire in the connector. So Tim is right- no RPM wire to worry about.

According to the schematic for '00...

Coil:1
Black/white = power
Brown/yellow = coil 1 trigger
Black = ground

Coil:2
Black/white = power
Brown = coil 2 trigger
Black = ground

There is no tach output. Tim is correct in saying the ECU provides the tach signal

Would this work with a Link?

i was comparing the wire colors to the ones you posted up lazzer, and looking at teh schematics, i saw the wire colors, i just couldn't find what they did

Attached - Toyata Corolla '04 schematics.

I couldn't attach it to the thread. Maybe an admin can do that.

Read the thread.

i'm just gonna sit tight until my coils come, and then i'm goig to source some connectors, and then wire it up, and fire it up, hope nothing blows up

Would this work with the AEM EMS?



hehe jk

how about my corolla?

Ban? :pitlab:

:gtfo:

HAHAHAHA
