I just completed the COP conversion! :cool: My car is a CA spec '99.
Fired right up! Thanks to everyone for the info!

Has anyone completed a COP conversion on a 2001+ NB running a stock ECU?

The reason I ask is,I was at Chikara Motorsports tonight and I was discussing COP conversions with the owner and he mentioned if anyone has done one on a 2001+ NB.The racecar he is rebuilding is in dire need of a stronger ignition system.

Any helpful info will be much appreciated.

Hi i won a set of 9019-02214 toyota cops and i wanted to know if any one has used them before.

I can get a complete set of toyota coils with stock wires and connectors, and avoid most of the soldering...?

what do You think of using stock toyota wiring harness to connect COPs?

im going to say hit me up with a price i need to do cops on my miata

Go for it. All that is left is to make the bracket and put the connector on the Car side of the harness.

Just in case anyone is interested, there a guy on ebay selling these COPs at a pretty good price:

He's also selling a lot of 50 for a great price too:

HOLY SHIT!!

Some one buy that and start mass producing PNP COP conversions (Sav get back in business) I would but they don't ship overseas :(

i will start making full plug n play kits with in next few weeks for 90-93

I've got a 93 that I would be interested in purchasing a pre-made COP setup. When you get going, send me a pm. Maybe we can get enough buyers to get a real nice price.

Just to let you know; I asked if they had any connectors (I was going to buy them from them because I can't find them locally) and they threw them in. If you get them from the guy on the auction (like I did), you might want to ask.

I've been doing a lot of searching and now I'm a bit confused. Will the COP conversion work with an EMB in the mix on a 94? Also, where is everyone tying into the coil harness? There is a gray plug up the harness from the coils that seems to have all 5 of the connections from the coils (power, gnd, tach, and both triggers). I found the exact plug (thank you pick and pull) and I'm using it (unplugging the coils at that spot and plugging in the COP harness there, but I can't seem to get it to work. Now I'm wondering if it's an EMB issue. HELP!

Thanks

Just wondering if anyone has had a problem with running this set up on a hydra ecu. I tested everything before gutting my igniter. Wired it up started the car and let it run for awhile. went out the next day and nothing. car has no spark. Unhooked two cylinders and only ran 1 and 3 and car started. Does the hydra not have a good enough transitor to pull to coils when cold or what?

Thank to anyone that can help: noob:

Dunno, but, that's hard to imagine, it's not a hell of a lot of current there. Perhaps the connections aren't good? I'd done my original install with butt splices and.. everything fell apart, I'd lose spark on the road (admittedly, months later). Soldering it fixed it.

There's a much bigger chance the signal is inverted, or the hydra (with a dwell time set for stock coils) cooked the coils. You'll need to look carefully at the settings, remember the dwell is much shorter so you could be cooking these.

fwiw I run stock Miata dwell times in the EMS and I'd assume, if properly programmed, the Hydra would also use the same dwell as the stock ECU. I haven't burned up any.

I ran it fine on the hydra. In full sequential ignition mode.

you need to make sure you wire the banks properly and (depending on version of hydra) set the sequential ignition functionality up.

and dont forget to set your dwell properly.

So, what's so bad about the Toyota COPs compared to the other offerings out there? Several people told me they don't work and provide no increase in performance...although I have dyno results to back it up.

Does anyone have thoughts or comments that a 5-year old can process?

How do I know if the signals are inverted. Also have a question about a capacitor that is'nt in the wiring diagram. what is it for and where does it go. could that be the problem maybe. The hydra has stock dwell times. Don't exaxtly know how to change them yet.

:noob:

Id also like to maybe wire them in sequential. Is it easy to return to stock ignition when using the hydra, or is there alot of work to put it back together. Hav'nt recieved any feed back from FM yet as there hydra guy is on a honeymoon.

Nothing is wrong with them. They work great - they are super fast, super cheap, a no brainer to set up, and they throw a spark the length of your arm. You could read by the light they give off running them at full tilt.

I think people got scared of the dwell time difference or the connectors, but there's no problems.

As to "dyno results", to first order, a spark fires or it doesn't. So, if you're running so much boost you had to gap down your plugs, put on the toyo COPs, and open your gap back up. You should get less missing, and that will show on the dyno.
