coil on plug

[siege]

so i put my coil on plug in to day and now the car will not cold start has any body else had this problem and if so what was the fix

 

[tjbiker031]

did you plug it in?.....j/k are you getting spark, fuel, hook it up right?

 

[VETTE_50_TH]

Go over the wiring once more. Those can be tricky. Maybe you have bad coils?

it it just cold start when the car has started and ran for a minute it will start right back up it revs good no missing. it runs really well it is just that fist start up.

Congrats on the downgrade.

Congrats on the downgrade.

My COP setup works perfectly fine once you get everything right, and it cleans up the engine bay very nice to. For the first week I had my COP setup I had trouble with cold start, I had to turn it over a few times to get it all the way on. After a while it just started working perfectly fine, just double check everything.

 

[Gamble97]

Congrats to you as well on the downgrade.

How is coil on plug a downgrade. They are going to have fuller combustion as opposed to waste spark, also your input was very insightfull.

Man go be negative some where else, nothing you have said has been helpful. I have seen a few people that have had problems with COP setups, but once you get the bugs out (if any); then a COP works great.

I'm not being negative, I'm being honest. I love you guys that do these "upgrades" and have no idea why you do them or how they work etc.
The coil on plug is a DOWNGRADE. Stock ignition is good for 600+hp all day long. You get a WEAKER spark with a COP UNLESS & ONLY UNLESS you have some type of ignition amplifier like a arc-2 or twinfire.
This is the ONLY way a coil on plug will be an upgrade. But hey, if you guys want to piss away your money on things because they "look cooler" then whatever, my spark plug cover, covers my wires.

He speaks the truth. These coils aren't very well suited for DSM's, they run different dwell times and are, indeed, taking a step backward from stock. DSM stock ignition is actually quite a robust system that can hold it's own. At any rate, I still run a COP setup however, I have an ARC-2 to help out, and I can control dwell times.

the car runs great its like what fear 19 said i have to turn the car over a few times then it pops off and i am not doing this for looks i will be getting the arc-2 amplifier but one step at a time.

Quick question. What year Toyota are the donor coils and harness coming off of? Ive looked around and even googled it and all im finding is the mentioning of Toyota. I found some of a corolla but they arent quite right any help is appreciated



PS you can just PM me instead of whoring his thread.

 

[latintuch112]

for you guys that used the COP set up and works fine with no problem what so ever...what coils did u guys use?

 

[turbotalon31]

i used chrysler 300m coils.. dont know how good it works yet dident fire it up yet

The stock system isn't designed for them so they don't work as they should. It's a fact, not an opinion, that they're a downgrade from the stock coils. Think of it as putting a GT42R on a bone stock DSM with no supporting mods or tuning mods.

Also, you must not understand a wasted spark system. The COP's are still going to be in wasted spark as there are 2 signals not 4 separate ones for each cylinder. 1&4 and 2&3 are still hooked together.

I have used stock coils and ignitor to push 800hp with the addition of a CDI box...

 

[VETTE_50_TH]

Only way to get rid of the wasted spark is to get a M&W 4 channel or something similar. ARC-2 and twinfires do not removed the wasted spark since they still work on two channel. However, the 4 channel CDi's are really expensive. A cheap way is to continue using the typical wasted spark design that our cars incorporate and get a cheap CDi if you use a COP.

 

[1gDSM4g63]

Gamble97 and gsxtasy tells the truth. The stock coil are good for 600hp. It's just huge waste of money and you need a DIS2, ARC-2 or somewhat ignition box to have a real advantage of a COP.

 

[kimcheefists]

I think the OP now understands that COP is a downgrade. Why not help the guy out with his cold start issues instead of repeating "COP is a downgrade."

 

[latintuch112]

talking about the waste spark...what about the Toyota Paseo...that has the one coil over one plug and a plug wire to one of the other plugs...thus the waste spark being delivered!!

I run a COP and now I don't have to spend $75 on a good set of plug wires every year and it unclutters the engine bay. Unless you're running 30lbs and making 500+, you don't need to worry about dwell times.

 

[snakeyes711]

I figured that the reason that most manufactures place the coils where they do is so they are away from heat. Its on the back side of the engine totally opposite of the exhaust man. I've found from experience, that when mounting coils over top of a hot engine your asking for trouble. They get hot, the windings expand, a whole lot more then they would if you mounted them off away somewhere... anywhere else besides on the top.

My bike ate three sets of dyna coils before I realized that mounting them under the tank near the valve cover was destroying their life I moved the new set in front under the triple, and that set has been on my bike for 2 years now. Thats what I've found by my experience.

,i dont know how youre managing to go through a set of wires a year but thats quite impressive my friend.and dwell times are important no matter what amount of horsepower.whether its a 140 hp corolla or 500+ hp dsm,controlling the amount of time the primary coil charges is crucial for any ignition system.


but where did you purchase the coils from? do any resistance checks on the coils? what kind of shape are your spark plugs in? what do they look like? getting any codes?

Spark is spark until you're pushing a lot of pressure to make it blow out and then you start to worry about charge capacity. I've seen COP setups on everything from stock to 600+hp, they all work fine. People that dwell on dwell times should be doing better things with their time. You should replace your plug wires once a year.

You can get coils from damn near anywhere, yards, ebay, stores, etc. Resistance should be the same between the four. My spark plugs (ngk's gapped to .25) look great. I don't get any check engine codes from having a COP.
