Tuning your EcoDiesel
 
Hello all - my company, in Long Island NY has recently partnered up with Celtic Tuning in the UK.

I would like to find out how many of you would be interested in tuning your Ecodiesel. I have used them for my other vehicles and they have come out great so I am really looking forward to trying it on our Grand Cherokee.

I will be tuning my own and will allow you to test drive if interested in the tune. Ecu's can be mailed in and shipped back within 24 hours.

DPF and EGR removal is available as well.

So, in the event my DPF or DEF system fails after warranty, I can "delete" them myself and send you my ECU for a tune with supported deletes? If so, then owning a 3.0 EcoDiesel well after the 5yr/100k warranty is much more appealing.

The dpf delete is for off road use only. We have seen what the Dpf's have done to engine, instant increase in mpg and power etc.

Why off road use only for DPF removal?

Likely because the vehicles will no longer meet smog/emissions standards without it.

Exactly. In NY it will most likely still pass our smog test BUT fail a visual test. If an inspector sees a missing dpf filter, the truck won't pass.

If you're pulled over by a police officer and they see a missing DPF, you can get a ticket.

Exactly. Much more appealing to me as well.

The large majority of our diesel repairs are on engines to do high rate of fuel in oil, dpf regen issues, egr valves and egr systems completely clogging with carbon. Such as her coolers bursting and allowing coolant in exhaust, egr pipes, turbos sooting up.

We had a 6.5 diesel intake manifold off of a 2002 school bus. The inside of this intake was spotless. Our tech actually walked inside the office to show us the differences between a 6.4 power stroke we have apart and a 6.5 old non egr and dpf Chevy.

Take an intake off of a duramax, Isuzu, power stroke, cumins, etc and it'll be coked up with carbon. We are just so used to seeing this now that it has become normal and the clean 6.5's, 7.3's are becoming more rare.


I would be ignorant to say that these systems are not really saving our atmosphere but to put it simply... Pay $3k to replace your Dpf, 3k for a sooted up turbo that can no longer be cleaned, tows to your local shop, increased wear on engine, must use synthetic oil that is made to soak up the carbon and other contaminants, and a DECREASE in fuel mileage ( 2013 duramax averages 12-15mpg, my old 2004 no egr and dpf averaged 19.5 at 170k miles).

Also- remote starting your Ecodiesel and allowing it to idle for 20 min is a BAD idea. I will show you some pictures of what happens when these diesels idle. Internationals actually turn the engine off if the engine is idling more then 11 minutes.

Can you tell this bothers me? This keeps my shop busy but I still don't agree with it.

It would almost be wise to remove dpf and tune the truck back to factory to bring it back under warranty. You'd be prolonging the life of the engine and attached parts as well as Increasing fuel mileage.

So what happens if we live somewhere where there IS no smog testing ;) ??
It would appear that removing/reflashing the ECU would cause a problem during warranty but, after warranty, removing all the gubmint demanded B.S. and reflashing the ECU would be most beneficial.
At least to those of us without annual smog testing ;) !!

Exactly. If you could find a local shop that has wiTech then you're still good to go.

Tunes are undetectable at dealers. The ONLY way they can tell that there is a tune is if the tech feels a difference in the way it drives and for ex if the max turbo boost is 20 and the truck is now boosting up to 25psi. Some hollow the inside of the dpf's there really is no way to tell. If you do a dpf delete only in the Ecu...

We are having multiple reports from the same people here in Aus with the DPF filling very quickly and failing to enter passive regen, and also failing to regen when it is telling the drive to drive at highway speeds.
They then go into limp mode and are having to get taken to dealers by tow trucks.
Oddly enough it is effecting MY14 when it was super rare for MY11-MY13s.

I believe it. That is odd though. I know the input rate of DEF fluid is increasing to lower emissions. Maybe the regen process has to be increased as well.

There was zero training when I picked up my diesel at the dealer on how and when the regen process will take place.

I don't understand why there is not a manual regeneration button on the dashboard. Only the dealer or shop that has wiTech can perform a regeneration using the laptop.

SNUKE 03-12-2014 08:47 AM

We don't have DEF in export countries, it is only Nth America. All are stupefied that there isn't a manual regen button. Of course if there was one, some idiot would do it while parked ever some dried leaves or similar. Dealers have an official form to fill out when they encounter this problem. It should not be happening.

We don't even get the diesel supplement manual you guys get.
