TOPIC: Duel Ignition Plug Mod

This link is for those with duel coil pacs or have 8 plugs on 4 cylinders.
Some say they feel extra torque right away and a smoother running engine and others say they didnt notice a difference or lost MPG.
Stumbled across this link by doing a search for problems with my B2500 not getting results with the groove. Seems like Ford Rangers are known for being stubborn for MPG increases but this mod has helped some get an increase in torque and MPG.

Jumpin' Jeepers, Karl, I never knew it wasn't setup to already be firing both plugs in the power stroke to begin with! Well, I read that thread through, the poster had no problems. Amd like was said there as long as one isnt trying to run lousy gas in it I don't see any reason not to try it. You already have Torquemaster plugs, right? If $$ wasn't an object I would use Granetelli MPG+ wires on that engine, non-resistor. But that's me! With the way Ford did this coilpack/dual plug thing is screams Factory Band-Aid to me. They might have a design that's inherently kinda inefficient, at least as far as emissions goes.

So the bean-counters made the Engineers come up w/ a cheap way to reduce the emissions to make the EPA folks happy! Cheaper than a more extensive re-design, or a way to stick with a design//tooling/factory setup they already had to get more model years outa it. I smell possible hidden power/efficiency here, buddy! A one minute mod easily reversible...I say Try IT!

. I smell possible hidden power/efficiency here, buddy! A one minute mod easily reversible...I say Try IT!

Yup, did it already.
Read about 60 posts on this with some very positive and some very negative but the negative in general was that there was no difference or a loss in MPG. So went out and did a one minute mod before posting the link on this board and noticed a little smoother ride when I got over 50. The Scangauge tells me Im getting better mileage but that will not be determined until I fill up the tank again. Scangauge has given MPG numbers that were not true before so I learned not to trust the MPG reading on there.
Wish I could get the fuel trim reading but my model does not give it to me with all the times I tried. Dan says that is the way to see what is really going on with the engine. Think I have to download another feature for this model to get the 02 readings since my research came up negative.

PS. Did the cable mod with the zip ties also.

Cable mod? ya mean the Nascar style where you make plug wire spacers from zip ties to keep wires separated? A cheap way to prevent ignition cross-firing, but one should not see that much nowadays unless using really Crappy plug wires anyway! But I've used it before, it does work.

I wonder if there is more to be had on this engine from further Ignition upgrades...? Might go back to see what else the serious racing types say 'bout this engine, I'm not familiar. But hey, it's only Money, right!

anyhow Karl, I'm very glad to finally hear of some gain on this 'lil truck! You've certainly been at it awhile now! Seat-of-the-pants IS a good indicator in my book anyhow.

And-thanks for sharing this 'lil Ignition trick, I'll remember it!

I followed the link in the first post the other day and took a look. Interesting….

Karl which scan gauge model do you have? I'm guessing the e.

Do you have a smartphone,tablet or laptop?

I have the Scangauge II and have a laptop and smart phone.
Is there a link to download the ability to get the trim readings on the Scangauge I have?

If your scangauge has the ability to use the x-gauge commands then you should be able to add the fuel trims.
