COP Coil-on-Plug ignition [Merged 1-8]

[v8s_are_slow]

I saw a thread where people were talking about different coils to try such as off a 300ZX, etc. Does it matter what coils you use or would the dwell problem exist with all of them? Haven't been able to find the answer as to what coils Buschur is using. I know the 300M coils won't work (not without an aftermarket ignition anyway).

Does the problem go away with a thinner gap or does it just make it less annoying to deal with misfiring etc.? I want a good running setup if I go with it.

I bought my cop setup in pieces. I got the cop's from the junkyard along with the wiring from a 300m. wired it up, and made a cop plate to mount them on out of CF. when my car was running last (its been awhile) I really didnt have any problems with the cop at all. my only problem was tuning with aem ems. I didnt have enough time to figure it all out. and when I get my car back together again, I will use the same setup.

btw I spent a total of about $100 including the CF, the cops, wiring, and the dremel discs to cut out the part.

no other CDI or MSD or anything.

I dont really know why some people have such problems with cop set ups.
I have one and it works great. I dont have a cdi and run bpr8es plugs gapped at .027.
I have run 35psi with gt35 with out a hickup.
I have a AEM EMS and the car idles and drives with out any misses.
I know this doesn`t help those that are having problems just making it known that there are people who have no probles with cop setups.

Where did you get the cf from?

 

[jasonlee]

oh, I ordered it from machv motorsports.... http://www.machv.com/cafiplsh.html

I used the 3mm thick stuff

The Stock Coils have done over 700WHP...why fix it if it aint broke?

 

[MyBeatGSX]

Well its definately broke now.

 

[MyBeatGSX]

What they don't tell you is that they had a CDI ignition system. I'd love to see someone who's done 700whp on a bone stock ignition.

However I do know people that have done 500whp on stock ignition with the Buschur COP. So even though it doesn't seem to work for most people (including me) it does work well for some.

 

[arash15]

someone with some real knowledge please address the original post. i am having identical problems with my cop setup and i have brand new coils as well. my plugs were gapped at .28 and now the car just turns over but doesnt start up, i left my brnad new plugs in and put the stock coil pack on and it started up with no problems. help!

 

[Staytuned]

If your car won't even start you need to consider that the trigger wires need to be switched on the COP. There is a difference in wiring up a 95-96 vs 97-99 based on firing order. When I first got mine in the mail it was wired for a 97 Talon, which would have been great if I had not been using DSMlink (95 ECU). I switched trigger wires and it fired right up.....but it misfired huge at WOT.

 

[MyBeatGSX]

Didn't I just post that I had the same problem and running a ground wire fixed it? Try the suggestions already posted before complaining that you want more.

 

[alexg1323]

its not a ground and two trigger wires its a power wire and two grounding trigger wires

Someone has run a faster time than you with stock fuel, t25, and fwd...why fix it if it ain't broke?

Just because one person managed to stretch certain things to oblivion doesn't mean it's the best way to do it.

THANK YOU!

You are my hero, I will love you forever. And I will link to this post about 3092478329 times in the future.

People run 11's all day long on 14b's (race gas), lets all sell our huge turbos and downgrade.

 

[Golden Wind]

I ended up wiring the 90 tach signal sender into the harness that I made for the coil packs and it works fine.

 

[ryan90tsiawd]

Has anyone bought this Coil on Plug kit from ebay? If so, any feedback good or bad would be helpful.

I've been looking at them. I want to make my own, I just need to find what kind of coils they use. I read one that claimed longer coil saturation time. That's a lie. These systems are still waste spark. The coil will fire once per revolution just like it did before. I don't think you will find much advantage. I just think they look neat. Remember when it comes to ignition you want not more voltage necessarilly but you want more millijoules of spark energy. If you're going to invest into your ignition system I would look at a MSD system or similar setup to give you more milijoules of spark energy! I hope this helps.

 

[blackbyrd]

If no one gives you a responce here, if you look at that guys feedback he's sold 9 of them, you could ask the people who bought them, how did they work out?

Edit:
Yeah a MSD would be nice. Good Post dieseltech!

 

[dieseltech]

I haven't looked in awhile but there's a company called Jacob's. Their ignition systems produce more milijoules than anyother. I cannot, however, vouge for either company as I have not installed either of their products. I have installed a MSD Pro Billet distributor on my 88 TPI camaro. It worked great.

 

[Spooling99]

I"ve been told that you could use the COP off a GSXR. I think the ones that go for like 400$ are a waste of money that could be used elsewhere.

 

[formulav893]

at what HP range should someone start looking into this setup?

 

[Spooling99]

Most people wont even get close to needing a cop setup. I believe stock ignition has went 9's.

 

[dieseltech]

The COP setup is mainly cosmetic. The claimed benefit of quicker throttle response and better acceleration could also be attributed to the distance the energy has to travel is much less. It is still a waste spark system, not a true sequencial setup. If you want to upgrade your ignition, look into an MSD or other type of setup that will actually increase the amount of spark energy. Although the COP setup does look nice that is the only reason I myself would consider getting it.

 

[AWD 90 Tsi]

I may have to look into that
