72 IH + ‘85 Alaskan = Questionable Judgment...

From my computer-averse point of view, correctly and thoroughly building a fuel and a spark map for EFI looks to be a BUNCH more work than setting up a carb.

Most of the system are plug and play. They automatically do all the tuning based on the parameters you set. When I did my T bird the hardest part was hiding the wiring.

Instead of screwing with jets, cams, linkages, and still having to play with the ignition... The EFI system did it for me.

Thing is, these systems are marketed as “self-tuning”, which is deceptive: they build a rudimentary map that is good enough for most conditions, and certainly good enough to accentuate the advantages FI holds over carburation.

If you want to get the most out of a Sniper (and I do), you gotta get a laptop, a CAN cable, and Holley’s tuning software, and build one of these:

This is a timing map (useful only with a timing-control distributor), but a fuel map looks similar, and both enable you tune your engine to its particular strengths at various RPM’s rather than relying on the generic resident map.

I say I’m computer-averse, so I’m anticipating an uphill battle.

There are shops that do it for you, save you the hassle of going thru all the learning and tuning.

As the Nevada loving gentleman previously stated, just have a shop do it. If I wanted every ounce of performance or fuel economy, I would refer to a professional with years of experience vs. me trying to figure it out as I went.

Gentleman? Okay.

Oh man, I missed that insult completely!! Your jeep pics in the spotted thread are starting to melt my eyeballs......

We Canucks are a sly bunch. Hey! Look over there! It's Anne Murray!
Whamo....next thing you know your shirt is pulled over your head and you can't see crap.

Ha! Not around here, there aren’t.

Besides, I want to try this. It looks interesting.

Yeah, none here either, have to go to reno for that, 170 miles!

It never hurts to learn new things!

It’s not a huge priority at this point, and without spoiling the tale I’ll leave it at that.

As it happens, this is where we are in the Saga of the Strugglebus:

New laptop with the Holley software downloaded-

And the required CAN cables-

Frosting for a cake that never really got baked.

During this time, Harry decided he wanted to sell his shop, and I decided I wanted to buy it because I was fed up with: 1. The Front Range of Colorado and its ever-swelling mass of idiots. 2. Working on vehicles outside in the dirt, heat, mud, and snow.

First, I had to sell this:

Leaving for Sacramento, good riddance:

Not a fan of these having spent my younger years freezing my ass off, sweating my cojones off, and compressing my spine in them. Apologies to their fan base.

A nightmare month of packing & moving, and voila:

New home.

Just gotta build a living space in that loft above the Jeep & Dodge.

Right around now, it’s time for the Labor Day trip to Red Canyon.

Truck’s recently fuel injected and packed; Walden or bust— nothing can stop me now.

Until the fuel pump overheated twice, attributable I thought to the headwind I was driving into.

When I stopped in Walden for gas, I noticed this:

No big deal, just retighten the axle shaft bolts.

And I noticed this:

Oil everywhere. I know I seated that dipstick, I know did, but still… must have something to do with the 20W-50 I put in.

Nothing to be done about that mess now, on to the canyon.

A great time was had.

Somehow, coffee just tastes better in a place like that.

Typically when the oil dipstick is pushed out (assuming it was fully seated), it is usually caused by a large amount of blow by pressure. Could be bad rings, hole in piston, breathers not venting. Oil weight is typically no an issue and I run 20/50 in a number of older vehicles that have a lot of miles. It helps with the low oil pressure of worn out bearing.

Thank you for the info, but stay tuned; remember, this was three months ago.
