All, I very recently installed the Eco Tune upgrade on my 05 and am checking out the mileage difference and comparing smoothness to stock etc but will hold off for a little bit before I offer up an opinion which at this point I fully expect to be positive. Anyone on this forum have some updates on the longer term results of the Tune?

Update:
4/13/10 I am very pleased with the eco tune, no problems at all and have had an increase in mileage and overall performance.

Been running the ECO since June of this year. Fuel econimy is still up there (winter blend diesel has hurt though), performance improvements still the same as when it was installed. Really like not having to go through the EGR problems - although as I have read there are many improvements since mine was installed.

All in all, still quite happy with the tune.

We would appreciate any feedback from customers that have been tracking their fuel economy during the last few month. Before tune numbers and after tune numbers along with driving conditions would be fantastic. Some customers have noticed the annual drop in fuel economy with the winter season. This is due mainly to the fuel blending of diesel and partially due to colder ambient temps. A 10% drop is fairly typical going from summer to winter.

Thanks,

GDE

GDE,

Hope that helps. Let me know if you want more details! I will be back in AZ next week and will reinstall my ECU (with the latest update). I'll be sure to report on what, if any, gains I see from this latest version! Thanks!

Stoutdog,

Thanks for posting your vehicle information. The results you are achieving are fantastic and the information is very detailed relating to driving conditions, speeds, and vehicle configuration.

I run this particular route every other week and fill up before I leave, and then again at the end of the day before the return trip.
400 miles:
-60% Higway 70mph
-30% In town
-30% back roads 60mph

Prior to winter fuel, I was averaging 32.5 mpg
Yesterday 29.85 mpg


Location North Carolina - coastal flat lands.
Temps stayed in the 30's

Widowmaker,

Do you remember what the vehicle was averaging prior to the tune in both summer and winter? The mpg you are achieving now is very good...almost double what a gas KJ will achieve!

Thanks,

GDE

To be honest, I can't remember the variables in summer and winter. The best mileage I made on that run prior to the ecotune was 26.8...and that would have been summer.

Here you can find the stats of my Liberty "Stock" from the last 6 months (June-December 2010) before ECO Tune.

And here are stats after Tune.

image

The driving condition are the same (driving roads and car load). The Car is always load with tools or people. The stat need to be corrected for about 4.5% (wrong reading of odometer). In real, the stats are better for about 4.5%
The wether here in Toronto (Mississauga) is very cold (-10C, -20C) for the time of my ECO Tune. But still, the average is better then last year.

I hope. it will help.

Hey Guys
I've been keeping a fuel log on my '05 Libby since I purchased her back in 10/05.
I started running the ORM back in mid 06 and my average went from 20.56 to 21.40 MPG.
I installed the Eco Tune on 04/30/10. Since then my MPG average is 24.18 (almost a 13% increase in mileage) which IMO, more than justifies the cost of the tune. Plus the Jeep feels more responsive and seems to run smoother. This average is based on mixed driving conditions (25% city, 60% town, & 15% highway) some of which includes towing my small boat. It also includes both summer and winter fuels.
I've been running XDP fuel additive which seems to also help a little with how the Jeep runs. For some reason the Libby gets better mileage with Texaco Diesel fuel.
I'm guessing that my next step will be to get the TCM tune.

Don't pick a fight with an old man. If he is too old to fight, he'll just kill you!

When I first saw you Fuelly I thought you were some kind of anti diesel troll trying to say the CRD gets 10-11 Mile per gallon, until I caught on to the 100 Kilometer Per Liter

I know, it is little confusing.

The stats after ECO tune may look not that very impressive, but starting January we had a very cold wether here (-20C / -10C) for many days. Cold starts do not help with the MPG (litre/100km).
But, the average is better then in June2010-December2011, before the ECO Tune. Last drive was great: 165km (100miles) on the highway in -6C (about 28F) and the average was 28.8MPG (8.2 Litre/100km).
