why are you always so negative ......

yes the stock wires are just as good as any others on the market....they are 8mm wires....

I'm not posting to be negative and I'm not trying to rain on anyone's parade. I'm just trying to help out, and in this case that means expressing an opposing viewpoint. Nothing personal.

so your more or less saying that this coil is pointless unless you have higher then stock compression... then why is mr jone's *** dyno showin noticeable improvement with his STOCK compression?

You can assign whatever weight you want to Mr. Jone's butt dyno report. To me it means very little. Not because I think he's a liar or a bad guy, but because I don't believe in butt dynos - particularly when it comes to measuring coil pack performance.

the coil pack WILL imporve the stock spark on a stock ignition system.....it is just like adding a MSD to a '79 351.........it is an upgrade to achieve a better spark......there is ALWAYS something that can be upgraded on a vehicle...

I assume this statement comes from the fact that you've already done this mod & didn't show any difference on a dyno...correct?
If not its only your opinion & sometimes opinions coming from some people are utterly worthless.

No, actually my position is based on the knowledge I gained while I was researching Ford's DIS and EDIS ignition systems for the purpose of putting together this article:

Summary of Ford DIS/EDIS "Waste Spark" Ignition System

Aside from any and all of the stuff I could read on the subject, my research also included correspondence with an electrical engineer who personally spoke with Motorcraft engineers about the design of the Ford EDIS ignition system, particularly as it relates to MC plugs and ignition parts.

Install process would be very very simple as I think its 4 bolts and you just follow which wires hook up where according to the instructions.

installation is super easy....4 bolts that hold it in place, then 1 wiring plug and then all the plug wires.....i would advise lableing the plug wires so you know which one is which, they dont go on the new pack the same as the old pack....

with this thing and the Bama it is a sweet combo.......right now i have the spark advanced 4 degrees in every rpm range....i am going to play with it a bit more tomorrow after work or saturday with a little more spark......

i drove yesterday about 88 miles and made it on a little less than a quarter of a tank.....that is less than 5 gallons....got about 17.6 mpg and only about 25 miles of that was actually on a highway were i could run 70-80mph.......the rest was on 2 lane highway....granted with no stop signs and the cruise set on about 63mph....

I'm going to attempt to change out the coil & wires today Maurice. I've got the Truck going in for a major service next week & will have the plugs installed with a .65 gap then. I talked to the service manager & he will make sure it gets done correctly. For some reason they know me & the truck very well after only a few oil changes.

couldn't imagine why ........probably because you are like me, would really like to be standing, looking over the guys or gals shoulder who is working on it....lol....

i think you will like the difference....whenever you install the coil you have to be careful with how the plug wires go back on.....it is different that the stock pack...make sure you lable them and then follow the instructions they give you with the new coil on were the wires go.......also you will most likely have to remove the orange (or whatever color it is on your truck) seal on the wiring harness plug that connects to the coil pack....if you dont it wont make a good connection and the truck wont start...

Yea, I've already made 2 diagrams, 1 of the stock setup & 1 with the change in the wiring on the coil. I would have done the plugs but I know I would have a problem changing them with 1 arm, had the problem when I did my 94 Ranger..especially the 1 passenger rear plug.
