COP help
 

im new to this place so im sorry if i have missed it, but i have found the thred about how to wire up all the toyota coils ect,
im really not sure where to wire in the capasitor :/ can anywone help?

There's no need to run a capacitor from what I've read/search, but to answer your question, the capacitor goes from your 12v to GND.

I'm assuming you're talking about Toyota COPS.

yes on the toyota coilpack setup, so your saying just to follow the diagram for the coil packs and thats it? no cap needed? plus i might look dumb now but the 12v to gnd is that on the coil pack loom?

Did you read this? It's the first thing that pops up when you type "miata toyota cop". Should answer everything. Some use capacitors, some don't. If you have one, it wouldn't hurt, if you don't it's probably fine.

Yes, cap goes in the coil pack loom, not sure where else it'd go.

Yes, to all three of your questions.

So now the last two posters have conflicting advice. One says capacaitor, one says no.

If you have it, wire the capacitor in, if you don't, don't worry about it. I don't have a capacitor in mine, and it's been running fine.

Huh?

was asking if urs is on a standerd ecu thats running fine

Oh. I'm running a ms3

Toyota cops wont work with a stock ecu. stock ECU will blow the coils because of incorrect dwell.

ahh ok thanks :) guess that plan is out then

this is untruth.

there are/were plenty of people running them on stock ECUs without any negative effects.

There was only an issue with NB setups, but it wasn't that they would blow, they simply wouldn't fire.


@rleete just did it--after a bunch of naysayers said not to--and it's been fine.

Stock ECU, 1994 model. No issues whatsoever. Runs better, smoother. I've been driving the hell out of it for two weeks in blazing heat. No problems at all.
