Full custom tuning in the works

Well it is confirmed. Custom tuning for the new ecodiesel is being worked on as I type this. The ECM has been fully mapped out and is in beta testing phase. I will update this thread as I get new details.

Sorry for being so vague, but not sure if the tuner (huge name in the diesel industry and VERY good with diesels) wants this information out yet.

If you mean Banks, it's public information and is being covered in detail on the "other" forum.

EFI Live is a tuning platform, not a canned tune. Various competing tuners all use the platform to develop tunes for supported vehicles. The best tunes don't come from Bullydog, Edge, or any of the other canned tune providers. A really good tuner with an EFI Live system and a 4wd dyno will be our best option...those tunes will be sold by the pro tuner, not EFI Live. I hope that is just around the corner!

The major benefits I see from tunes on our vehicles is fixing the emissions related issues we are having - as this seems to be our Achilles heel. With how they put on the DEF injector it seems as Jeep added this as an afterthought and the cost of repair and parts they charge to fix them is almost criminal. For instance, just the price of the actual DPF pipe the previous diesel JGC (WK) was $4,500 (quoted from the dealer). The Service manager laughed when I said hell no and the technician said I could get a tune and a DPF delete pipe for 1/4 that price which is what I did.

If the new tune would allow owners to disable / delete the DEF system to get rid of that reliability issue (of course at their risk with local emissions testing - if any) and or allow delete of the DPF system as well providing even more fuel economy (I bet a DPF deleted and tuned WK2 diesel could get 40 mpg in aero mode with a conscious right foot).

All they need to state in their sale documents is "for off road use only" and then they should be clear of any defeat device and it's the owners liability if they get caught.

With the previous CRD I had a DPF delete and mine did not have any soot or black smoke coming out of the exhaust even with the GDE EcoTune (440 ft lb torque). A modern diesel engine (unlike the HD rams cummins) engines are built very clean and run much hotter than normal diesels so they create less emissions outright.

My Cummins does NOT have any black soot on the side or back of it and it hasn't had any EPA junk on it since day one.
A properly tuned Diesel should NOT 'roll coal' as the kids say.

You know, I would probably prefer to keep the SCR and delete the DPF, albeit with a few tweaks to the SCR system to make it less of a princess.

As far as I understand it, the urea ameliorates the traditional diesel smell. The DPF, however, is just a pain in the ass that robs fuel efficiency and performance.

ETA: Haha, apparently I'm wrong about the SCR. I'd rip them both out.

I agree that modern street diesels are tuned for minimal smoke. However, any tuned diesel that has really good (best possible) off idle performance will be tuned to the point where it overfuels slightly and therefore soots. The laws of physics can't be broken. If our beloved diesels don't emit soot, then what are we catching and incinerating in our DPFs?

Granted, most tunes are setup to be street friendly and the fuel maps are leaner off idle to prevent smoke...but best response and least lag tuning will produce some smoke. Watch the modern diesels run on the track or pull. They smoke until the turbo meets demand.

My old Mercedes doesn't roll smoke but I can see a light haze if the sunlight is at a low angle behind me...and a white glove test reveals soot on the bumper accumulated over time. The newer ones are much cleaner, I'm sure.

Has anyone else noticed that our GC Diesels have extremely clean tailpipes? I'm amazed. I was showing a guy how clean and we wiped the inside tailpipe of a few new gassers sitting close by...black soot. My GC was clean. Amazing.

I suppose these kinds of definitions are relative. I just swiped my finger over the visible black exhaust trail area in my tailpipes and each swipe left my finger with a coating of black soot.

I suppose they might have been cleaner if I regularly scrubbed the inside of the tailpipes, but that seems like an odd thing to do.

This is the first reference of an ACTUAL DPF/SCR delete for the NAFTA model!
I think it's amusing that modding ECU to allow modifications to the DPF/SCR equipment has generated the most excitement in this thread. Maybe it's that most of those who are replying are fairly satisfied with the vehicle's performance in stock, with the exception of the finicky DPF/SCR. I wouldn't mind a performance bump, of course.

Oh yes, I know all about "lighting up the turbo", but it sounds like my Cummins runs pretty much like your Benz. very little soot. Now, I only run a timing box on the truck and it's a nice kick in the pants, but there's more in it if I fueled.... I.E. If I ever get around to installing the 100hp injectors, I'm sure I'll have plenty of off idle smoke.

As for the Eco.. it is pretty cool how it puts out no soot, no smell, etc... it's truly a clean diesel at the expense of MPG/Power

/Edit

Cleaner than gasser tails. Especially direct injection turbo gassers. Think Ford Eco Boost

SRC don't affect the diesel smell. My E-class has only cat and nothing else and you can't smell diesel fumes but if I switch to the straight pipe is like old smelly truck. It does blow some soot out when I step on the gas that is been accumulated in the rear silencers but not much.
