6.7 CR swap into a 1st gen?

[Farmboy92_2009]

ok fellas, a buddy of mine and I were sitting down and thinking the other day about what all a guy would need to do the swap. i know obviously the engine, ECM, and wiring harness.....BUT where im confused at is if a guy was to tune it with EFI live would he still need a standalone to run the engine or not??? thanks tater

Not too many people here would know.

However, on CompD, you can find your answers. I know I saw a thread a couple months back about an Ford 6.4L to Cummins 6.7L swap.

There is a guy on dtr who put a p-pumped 6.7 in a 1st gen.

See here:

That is Ron Allen. He has the most powerful 1st Gen bodied truck running fuel only.

awesome thanks guys!

So, WTF am I, just a damn stump, or maybe one of the people who would know?

Mark.

Mark i believe you fall into the category "one of the few that know" around here. I have a idea what is needed but thats about it.

Mark, I would consider you the Stumpy guy that would know.

I don't know wth Tater Salad means by "stand alone", that's why I didn't answer. The ECM runs the engine, and that's what you would tune with the EFI, so that should be all you need. I've done a lot of trouble shooting on the electronics on 6.7's so i have a good idea whats needed to run it too. When they 1st came out I thought it would be a wiring nightmare to put a 6.7 in something. Now that I've seen how it's set up it wouldn't be hard at all.

[Mark Nixon]

The LAST thing I'd try to run would be the 6.7 ECM, simpler in most cases is better.
That having been said, Pete's right, if they'd tried to do a viable DPF system in the '90s, it would have been an outlandish clusterduck of wiring, hoses and modules up the ying-yang.

Sad thing is, the only thing that's going to stand a snowball's chance of keeping up with the EPA, is computer technology.

If you must have EFI Live and you want tune-ability, the '06-'07 5.9 system is tune-able via EFI Live, plus you can do away with the VGT and run something of real value for a turbo, if not a compound set-up.

If EFI LIVE isn't in the cards, then hands down, the DUMBEST Commonrail system you can run is an '03-early '04 manual trans ECM and wiring, preferably from an HO application, then add a programmer.

I kinda' like the idea of the '06-'07 5.9 ECU and harness, because, stupid of a reason as it might seem, if you put it into an older vehicle, the APPS isn't a PITA to work out.
Just mount the pedal to the floor where you like it, run the wiring to it and DONE, no figuring out APPS cables or routing and mounting places that a cable will handle.

In truth, the SIMPLICITY of the EFI on a commonrail is what makes me hesitate on continuing with a mechanical version. Mechanical DOES rule from a simple and "fixable alongside the road" standpoint, but there's nothing bad to be said for that extra kick at the flip of a switch, either.

Mark, you are one of the few.

Pete, stand-alone is short for stand-alone ECM. It is a computer designed to run just the engine. Zeus and Bosch both have one but they are pricey. Like $7-$15k...

[Farmboy92_2009]

thank you fellas, lol i think the coolest thing would be is having an EFI live sticker in the back window and people laughing at you until ya open the hood ha but the only reason my 6.7 came into play is because they seem to have more "grunt". they have more drive pressure which in turn spools a charger better per say. now im not saying a 5.9 is out of the question either....but id like to have the option as the motor "grows" so would the tuning capability too.

and jon, the Zues isnt quite that much, i believe now its only running in the $3500-$4000 range, yes the bosch standalone is quite up there! i wan say ya its like $10k.

[PToombs]

Jon, that' what I thought he meant, but didn't know why he would need that AND the ECM.

You guys have to remember I'm on the industrial side of things. We are only getting Tier 4 stuff in the last year or so. We have alot of 6.7 engines with CR and no DPF, catalitic exhaust, etc. And an ECM from a loader with a 6.7 is fairly simple. Wires to the speed sensors, injectors, fuel filter, temp sensors, fuel control module and some other minor stuff. All you need for inputs is power, TPS, ground, and maybe 1 or 2 other things. So to me it's not a big deal to run a stock ECM, from a loader anyways.

[CumminsPower59]

Pete, we got neutered 6.7's in some of our new JCB backhoes, called HMEE's ("hemi's" ) There isn't much to them, pretty basic, just like you said, no dpf, cat's, etc. They are rated around 180horse or so...
