Thanks for the reply-

So do I need to accommodate those sensors? Or if I make a pipe can I eliminate the need for them with the software entirely? The pipes for the 6.7 cummins look to be just a straight pipe, no bungs for sensors at all.

Today I received and installed the Eco tune on my 2007 WK Overland. I bought the flash tool as well.

So far:

Incredible. You can feel the improvement in turbo response almost as soon as your foot pushes the pedal. I also noticed that keeping at cruising speed (60 or 80 km/h in my area) requires a lot less depth on the pedal than before. It feels like your foot is barely touching but you just cruise. Off the line performance is greatly improved, but I noticed it more at low speed acceleration; downshift and punch it at 50 km/h, (or punch it and let it downshift) and I was thrown back in my seat. My vehicle before this was a 2007 Acura MDX, and this experience in the WK reminds me of that acceleration. It could just be me but it seems like it starts a little faster as well. Again, maybe its just me, but it seemed a little louder also.

I can't wait to tow with it.

Here's my fuel economy data

As a very welcome surprise these days, I had amazing service. Keith is always fast and courteous on email, item was delivered as described, and Keith went out of his way to make sure I had the tuned engine control file very, very quickly after I had sent him my original, all by email.

More to come later, but so far I would highly recommend this product.

Your economy data is all pre-install correct? It's about the same numbers I am getting, which I haven't done anything to my CRD. I am getting pissed with Inmotion. I've left multiple messages and called a half dozen times, no response. Glad to know there is an alternative.

I think I may try the Custom Spooling option that deletes the DPF...

Larz12345: Yes, that data was all pre-tune.

I should have some preliminary data in a week or two, depending on how long this tank lasts.

how was it getting the tuner shipped to Canada?
I live in BC, so usually the wait time is around 2 weeks...

I've been running the ECO tune for some time now. Getting 23/24 on normal driving in the city and almost 25 if I baby it. Highway mileage is about the same pushing 80 mph.

How much collected pre-tune data would be sufficient? Just picked up the CRD and I'm interested in the getting it tuned.

When the hot tune is released will it be an additional cost? I'd like to be able to switch between the Eco tune for daily driving and a Hot tune for when it's desired.

We would like to see at least 5-6 tanks of pre-tune fuel economy data.

We are not planning a HOT tune at this moment, the ECO tune is already fairly hot. If a customer requests more power/torque we can meet their needs. The newest European applications with this motor are able to get close to 270hp. Our concern with the WK is the turbo and fuel system, we heard these are different on the latest Euro motor and the WK may not have enough airflow with the stock hardware to reach 270 without high exhaust temps. If a HOT tune is released it would be $150 as a second tune.

I'll start keeping data just in case...though it may take a while to get through 5 tanks.

In post #7 you said you had a hot tune in testing, so I assumed one would be released.

Thanks for the info.

Ive had the ECO tune for a while now, love it completely! I've dropped to 12.5l/100k city running, and the extra torque down low is awesome off-road.

On the power side, at Mopar Sunday just last weekend Stu ran a 14.9 at around 94mph on the 1/4 mile, running 265/70 all terrains but has a custom 3" exhaust, no other mods at all! Eat your heart out Hemis!

Top job with the tune Kevin!

Fuel economy data updated. Just got 11L/100km (21.5 mpg) in the city with a ****load of WOT off the line.

I had some issues with the CRD earlier this year. The dealer ended up replacing the turbo, the EGR and ECM. They told me they replaced the TCM too but I don't see it on the service record.

Anyhow, I'm going to replace the fuel filter and hypermile this next tank with a view of achieving better than 10L/100km.

So far the tune is delivering as promised.

No, I don't think so. I talked extensively with Keith about how the tune works and through my discussions with the dealer about the issues with the vehicle, it seems highly, highly unlikely. In fact, I think the tune helped keep the vehicle working for the 10 days between when the new EGR valve was ordered and when it was installed. The EGR valve was opening too far when it opened. The GDE tune disables EGR function (someone correct me if I'm wrong, maybe it only reduces frequency? is that possible?) so I was able to keep the vehicle for our summer vacation. Without the tune we would have had to rent a vehicle for 10 days and tow our boat with it. As far as the ECM replacement - I don't believe it needed replacing. The dealer saw an opportunity to do $10k worth of work at no cost to the consumer, so they took it.

Plus, the issues worsened when I took the tune off.
