Coil On Plug [Merged 5-7]

[Mark90gst]

coil 1+4 and 2+3 get wired together and they all use the same ground, hence giving you 3 wires total, and you have 3 wires in the plug on the stock coil pack, wire them in done,peice of cake, works great on my car.

You guys do realize that dejon tool sells a cop setup for $269 right? you just gotta splice some wires... or a plug and play setup for $299.

"Replace your DSM coil pack and wiring with this state of the art ignition. This eliminates problems associated with bad wiring and poor spark at high boost and hi-rpm. One customer having poor spark at 25psi installed our C/P and raised boost to 32psi before spark problems re-occurred. Plug boots protrude out the bottom of the plate. You simply set the assembly onto the valve cover, screw down the plate and plug the supplied wire connector into your stock coil connector or splice in a non-stock connector. Coils are recessed to clear the hood. Fits 89-99"

Just thought I'd let ya'll know...

I'm pretty sure MOST dsm'ers are gunna want to take the cheap way of doing a C.O.P. setup. $130.00 VS $269.00.....

I'll take the $130.00 and buy the 4 coils that I need brand new. Same exact thing, minus a metal plate.

AND THEY TOYOTA CONNECTORS!!!! where can I get them?

off of a toyota around the same year. Then just solder the 3 wires on to that connector and plug it into your car's harness.

same year as my car or same year as the 300m?

 

[krisj144]

I made a setup for my car, and then decided to swap back to the stock ignition setup for other reasons.

If anyone is interested, I'll sell the toyota connectors and wire leads (also needed) for 30 shipped. I have enough for two extra sets.

I've also got a full COP setup to sell that is plug and play, with coils, connectors, aluminum plate, etc. PM me if interested.

Here's a thread I wrote up on a local board about the COP. I'm 'akamiami' there. click here

Sorry if you have to signup to view it, I'm not sure if that's the case though.

Make sure you wire the coils in series, NOT parallel. I.E.- 1 and 4 together, 2 and 3 together

The reason for this. Say coil 1 has a resistance of 1.01 ohms, coil 4 has a resistance of 1.005. Most of the voltage will go to coil 4 due to its slightly lower resistance value.

I just wanna make sure you realize, its pretty hard to do it in parallel.


how did you manage that one?

 

[Gamble97]

Is anyone running either of these? I was thinking about the MSD ignition then I found the Dejon coil on plug setup.
Any input/opinions would be great.

 

[mn95TSi]

unless you are running a pretty extreme setup my guess would be that the coil on plug is overkill. many high hp dsm's don't use it, so don't think it's necessary. seems like a level of precision that most normal cars, especially street ones, wouldn't need.

 

[keymaster]

The stock ignition on our cars is good for ungodly amounts of power, like in the neighborhood of 600whp or so. Unless you're just wanting it because it looks "mad tyte yo", then knock yourself out.

 

[V62GST]

sorry to bring up year old thread.. but i have a question that needs answer

i know that COP will be in a better use and also overkill for nearly stock DSM's
however i have misfire issues aka studder/hesitation, and CEL with "misfire"
now do you guys think this will actually solve the misfire issue? or even a slight chance?

I've tried everything. boostleak test, replacing ignition coils, plug wires, (NGK, acel, manacore, nology), and plugs, plug gapping, time belt adjustment,

this is my current list of mods
98 GS-T,
Fidenza fly, NGK wires/plugs, harden IC pipes, Apex-I filter, Megen DP (no cat), Greddy EVO-2 exhaust, HKS TT, Greddy type-S BOV, Excedy clutch
i want to do more, but if my car keeps studdering then its not worth it

 

[Talesin]

Sounds like the ignition system might not be to blame, if you've swapped all that out and the problem isn't fixed yet. Moving to COP will be unlikely to resolve the issue. Best to figure out the actual source of the problem, than throwing money at possibles. Some CELs will be thrown even for a totally different problem; usually electrical in nature. :b

Did you test the power transistor? Are all of the honeycombs present in your MAS (a 2G MAS should NOT have any honeycombs removed, it flows well enough)? Is your BOV recirculated properly? Have you done a compression test? Have you checked your fuel pressure, to make sure that the stock FPR hasn't failed and being overrun, or the stock fuel pump isn't weak? Have you pulled the spark plugs to do a plug read? Are you using NGK/Denso BPR6ES or BPR7ES, and gapped to what? Have you listened to your fuel injectors to make sure they're clicking along properly?

 

[gotgrip666]

i was wondering what were the ups and downs on goin coil on plug and also if anyone could recomend a good ignition? i look at the parts catalog all the time and only see spark plugs and wires

 

[snowborder714]

Well, cop's won't give you any performance gain as the stock ignition is more than enough. They do look really great though and will clean things up a bit by eliminating wires. Also, you won't have to buy wires again!

Here's a quick search I did so you can see some threads about cop setups (there are also some results for police, aka cop, so don't mind those):

About the only benifit is looks. There are some people I know that switched to COP and had a misfire issue, switched back to a stock setup and cleared the problem up.
I think they said it has something to do with the dwell time of our stock coils.

 

[DirtyBirdRacing]

My personnal opinion is that it isnt worth it unless you have money burning holes in your pockets and you have done absolutly everything else to your car.

Im going to be extremly pissed if my coil on gives me a missfire again (especially if its as annoying as the inverted cas missfire)

I bought mine when i switched to a magnus because you loose the stock coil pack mounting on the intake. I def wasnt going to put it on the fire wall, you can also put it in the innner fender

 

[talonguy91]

It's a little more efficient for your spark plugs. But it's a little trickier to tune wit COP.

 

[SFRacingGST]

talonguy- can you please explain your last post. Why would it be harder to tune with? I just got on and hoping to get it up and running this weekend, just wondering what difficulties i should look for

It is worth it if your coil packs are shot, and you are looking to buy new coil packs and some good plug wires. Then the price is very similar, and you don't have to use money that is "burning holes in your pockets". There is no difference in tuning it for me, and I no longer have a coil pack on my intake manifold, and no spark plug wires to worry about.

 

[daren_p]

It seems like if you want to run a COP setup, you need an aftermarket ingnition system as well as most I know have missfire issues. You can usually clear up the issue by gapping the plugs smaller but this defently isn't ideal & you would end up with a downgrade from the factory setup.

Yeah, you're right. I was just assuming that his coil packs and wires were fine, and that he was just asking a general question.
