Green Diesel Engineering tune for WK

We just recently released a fuel economy and performance tune for the WK CRD. The pilot users report a 3-5mpg gain depending on drive cycle. We minimize the potential for EGR issues and reduce the soot loading in the oil. 0-60 mph times are reduced by about 1 second and the turbo is more responsive off the line.

Below is a link with more information pertaining to the tune.

http://www.greendieselengineering.co.../list/136.page

Our first tune was on the KJ CRD, we have yet to see a dissatisfied customer!

The tune plus handheld flash/scan tool is normally priced at $750, however the first 10 members on this forum to purchase the package will receive a $250 credit. Hand calculated fuel economy data for your vehicle pre-tune is a qualification for the credit. We would like to then receive post-tune fuel economy data for peer review.

Feel free to call us or email if you have tune specific questions. Thanks, GDE

wow the description reads well. So a user can load and unload this tune at any time? e.g. dealer service time?

I'll pass. I asked GDE last week for help with an issue with my Liberty CRD and they blew me off. I'll get the immotion tune for my Grand Cherokee CRD

Drewd,

Since when? As I answer the phone and have never turned down helping someone out with their CRD. You sure you called the right number?

Suzieque,

Yes. With the flash/scan you can change back and forth between stock and tune in a matter of minutes. The tool also reads/clears the engine faults.

"The 0-60 mph results show the GDE tune to be about 1 second faster than stock."

That is very impressive, do you have specific times?

The WK CRD we tested baselined at 8.3 seconds and with the GDE tune it dropped to 7.3 seconds. Of course, there is vehicle to vehicle variability in baseline performance based on mods and tires, but the tune will average a 1 second improvement from where your CRD is currently running.

We also have a HOT tune in testing that increases the performance beyond the ECO tune, however at this point we are not selling this as we have not accumulated enough data on the effects to the DPF regeneration frequency.

Thus far our WK ECO tune does not modify the DPF functions. The DPF regeneration on average costs 3-4% in fuel economy penalty. This is primarily from the very late main injection and post injection events that dump fuel into the exhaust (in the form of hydrocarbon) to heat the DPF to 600+ C for 7-10 minutes every 750 miles or so. We may look into this more, but this also substantially increases the cost as the exhaust would need to be modded to remove the DPF and have provisions for the sensors.

Id be interested if we could get a DPF delete pipe and a tune as a package for off road use.

I think as the CRD jeeps get up there in miles, and get closer to DPF replacement time, the interest in a tune that allows DPF delete will greatly increase.

That's exactly what I'm hoping for, but the limited number of these vehicles on the road, is it makes it difficult.

Can someone verify that this is indeed the DPF for the CRD?

Looks pretty simple. Is that fitting the only bung that will need to be fabricated?

I may need to start a new thread for this. Sorry for the Hi-Jack.

Yeah that's the DPF. You can tell by the two metal lines for the pressure differential sensor when you look underneath. There is a cat up close to the engine and another shortly after, both before the DPF, past the DPF is the resonator.
