2g coil on plug, ruined anything?

[obx tsi]

Has using a cop ever ruined anything on anyones car? Just wondering as I have found one for 100 dollars. Put it on and car ran just as good as with stock ignitiion. Just wondering are there any possible side effects down the road. Please respond with facts, not opinions on why I shouldn't use cop. Thanks.

I think I have read every cop thread on this forum. In all of those posts, I have not read about anything getting ruined. As long as the wiring is correct, I would say the worst that can happen is a missfire or missfires.

I would just make sure all of the solder joints are secure. If it runs ok then I would not be too worried.

Hope that helps,
Justin

Thanks for the reply. I have read a lot of them also and was a little worried when I installed it. I thought it would not work at all but was suprised that it ran just as good to me. I guess I am just paranoid. Wonder why some people have trouble and others dont? Anyway, I am happy with the coil on plug and think it is worth it if you find a good deal on one.

I wish I knew why cop worked for some and not for others. I think it is a result of at least one of the following:
1. Improper wiring
2. Switched trigger wires to the connector.
3. Bad coils.
4. Springs not making solid contact with the spark plugs and coils.
5. I think some people experience the dwell time issue that has been discussed over and over again, while other do not experience it or just are not affected to the same degree.

Anyways,
I hope it all works out for you.

Well, let me just say one thing. If you don't have the ability to set the dwell, changing coils is pointless and/or stupid.
Also, you really should never run COPs in parallel, they're not intended for wasted spark operation and you're just doubling the current taken by the ignition (and doubling the heat in the coils) with nothing gained if you run them in parallel.
In other words, COP setups are something you should only run with a tunable stand-alone ECU that has 4 ignition outputs and configurable dwell. If you only have 2 ignition outputs you're much better off with a pair of good twin output coils.

I do not disagree with that at all, but I do not see how that helps him with his question. Everything you said is already in the merged cop thread.

For many, including myself, going with a cop setup is not for performance purposes. I have a jmf smim, which does not have a convenient place for mounting the stock coils. That is, unless you dont have a/c and mount them there.

My sole purpose for going with cop was to help clean up the engine bay. I was fully aware that if anything, this was a step back for performance without the addition of msd dis2 or equivalent.

Ok, so I guess he is saying that I could ruin the coils. Well I was sick of plug wires failing and if this works for longer than two sets of plug wires then I was better of. All it has to do is last more than a year and it will be better than plug wires. Oh well, thanks jshuman for your response.

I am looking into changing to cop for the same reason, new plugs (ngk bpr6es) every two months and wires every 4 - 6 months ( magnecor and ngk ) getting sick of it.

Wildman95GS-T, if you are going through plugs and wires like that, you have somethine else going on.
I've changed plug wires three times in the 15 years that I've been driving a DSM.


If you guys are running low boost, you can get away with running COP but I can tell you from first hand experience that the OE ignition is a much better system, putting out a spark of greater duration and higher energy.

COP works well if you want to invest in a CDI box (Dynatek, MSD, Crane etc.) but on it's own it pretty much sucks.
My car falls on it's face at anything close to 20psi with COP but 30psi is no problem for the OE coil and plug wires.


Justin, baldur's post was accurate, no need to post a silly "beating a dead horse" gif. The OP asked why he should not use COP and baldur replied with solid info.

Any idea's as to what could be going wrong

yes! I was looking into COP, but thankfully i did a SEARCH, here on dsmtuners, the button is right at the top of the page and there were some really informative and technical posts regarding why OE ignition is much better, and you really only see advantage with said above. I was really getting into it because of how it looks, but after posts I've read, I will just stay stock.

What heat range are you using? How is your tune? How hard do you drive the car?

Are you using the wire loom/separators? Do you frequently wash your engine or do you live in a wet area?

What heat range are you using? I use ngk bpr6es plugs

How is your tune? I am still running stock turbo and fuel supply system. I only have aftermarket exhaust, i/c piping, intake and jet chip. I live in the deep south and there are no shops that can tune a dsm.

How hard do you drive the car? Only occasionally drive hard. 65 miles round trip to work everyday. The last two times played around it cost me lots of money 1. spun rod bearing 2. fried clutch.

Are you using the wire loom/separators? No.

Do you frequently wash your engine or do you live in a wet area? No.
