I see some talk about COP's, but not much on ignition mods.

Who's done either, or both, -and-, was it worth it?

I'm thinking there is still gas to burn in these gas-guzzlers.

 

The stock ignition can about ignite water. I don't think there's too much to gain with ignition upgrades, unless it's on a heavily modified (big power all motor, nitrous, blower, etc) engine.

 

Anybody else want to comment before this thread dies?

 

I replaced #4 COP on mine due to a electrical short that killed it....

When I replaced it, I noticed that the P/N was totally different than the one I got from the Ford dealer.

Once the COP was installed. I noticed a notable difference in power, especially off the line. Just for replacing ONE COP.....

Now, either this COP had issues or was weak from the factory AND/OR was an old version that they updated. Thus, the new part number.

I replaced one COP and noticed a difference. Maybe I should replace the remaining 7?

Strange but.... I think there is more power to be found in ignition than this forum leads you to believe.


HAS ANYONE REPLACED THEIR OEM COPS WITH AFTERMARKET COPS?

Please chim in!

 

All of the Mustang guys will tell you that the OEM Ford COPs are the way to go. The aftermarket COPs don't do anything but burn out quicker.

 

Com'on Thump - But this isn't a mustang....

But maybe so on a mustang or a lighting.

Dude... that is like saying my honda doesn't see any gains from COPS, so your truck won't either.

Just because a mustang(with a different engine and electronics) doesn't see any gains doesn't mean something else won't.

I noticed a power change on a truck I've drove for 3 1/2 years simply by replacing one COP....

Explain that..?

 

. . you replaced it with a Ford OEM updated part, NOT an aftermarket part. Exactly why I'm going to compare apples to oranges. You noticed a gain with a Ford part, hard to believe but I'll let it go since you probally did have your PCM reflashed when the work was done, maybe not though. The Mustang motors are VERY similiar to ours in terms of well EVERYTHING.

Just like Quintin said, you're not going to find anything better than factory stuff in this department unless you've got some other needs that the factory stuff can't fill. This is all my opinion. . again.

 

You just contradicted yourself, earlier your compared apples (F-150) to oranges (mustang).

The motors aren't even the same displacement. So no, not "everything" is the same....

Yes, I replaced the part.
No, I don't let the dealer touch the truck.


The 10K post + “thump” has spoken NO gain according to him….. So what “Thump” says… well… it is what it is….

Let this one die.

 

No you misunderstood me. We were talking about aftermarket COPs. But you said you noticed a gain with a OEM part which isn't an aftermarket COP. Thats all.

Once again, you misunderstood the CAPs that I had placed on those words. .

How many miles were on the original COPs?

What does my post count have to do with anything?

I agree though but you wanted everyones opinions. I gave you mine. I'm sorry you don't like my opinion nor Quintin's. Thats the way the cookie crumbles.

 

Don't get you panties in a wad bro!

I love'd your posts, and Quintin's too. Mostly yours though... made me laugh.

Anyway, the COP crapped out at 46K. Due to a short on the wiring plug.

P.S. check you PM thump... got that HID info for ya.

 

Ok,

So what about ignition modules? MSD has a sale going-and they want us all to know about it by pulsing the ad in the banner above...

I knew a mustang owner who had one and liked it in the past.

Is that a decent mod, or a waste of money?

 

The heads and camshafts are the same.

 

From what I understand, the oem COP's are superior to the GMS or MSD cop's. The bottleneck or weak link is the factory cop connectors, I equate this setup as like trying to shove 10 lbs of s**t thru a 5 lb bag. When you use aftermarket cop's you are only shoving 5 lbs thru that bag, even with aftermarket connectors you still only have 5 lbs to shove, but now it is going thru a 10 lb bag, that is why you see no gains. The best combination is to use OEM cop's with aftermarket connectors, that way you are shoving 10 lbs thru a 10 lb bag.

 

I have the GMS COP's I thought I had an issue with them I sent them back and put the stockers on. There is a seat of the pants difference,GMS are better than the stockers... for me anyways

 

I have GMS COPS and they due make a difference. However I have had my second one fail in less than a year. First COP failed at 12K and the second one failed yesterday at 21K. The stock connectors are wound wire that stretches out to almost 6', the GMS connectors are a solid piece of wire for less resistance and a better spark. For a NA application I would buy the GMS connector kit verses the whole COP. I am still up in the air about these GMS COPS, I may try Accell COPS next.
