I've heard that.

That was nearly 2 years ago, I'll probably start monitoring EVIC vs manual calcs again and see whats what.
...
Anyway extra mpg wasn't the primary reason for a tune, I wanted the EGR and swirl disable, and for the drive to be more responsive, so it feels less like forcing something heavy to do something it didn't like.

Fuelly.com is a great site for monitoring fuel use. Just put in the car details when you make your account, then add fill ups when you refuel. As long as you always fill it right up it's very nice.

Just put in miles and litres used and it does the rest for you. Can display us imp mpg and l/100km. Also tracks cost, and there is space for notes on the fill ups for things like evic reading.

Here's mine, when I remember I put the evic reading with the fuel up. Remember to reset evic with the trip computer every fill of course.

Yeah I've seen that around. Just not that fussed about MPG - lol as I've got a 1.0 VW Polo to fall back on when I want(need) to save money.
I always reset every fill, also just remembered that I also converted L/100 to imperial MPG, and coz that matched my hand calcs THATS why I ditched my conversion sheet all those years ago.

Keith (GDE) emailed me with a HOT tune today (Sunday). Now that's a great service!!!
Scooted straight out an loaded it to the Jeep and took it for a spin.
Leaving town I felt slightly more vibration through the pedal, a bit more diesel noise, various noises in fact. HOT may be a short jump from ECO, but makes the Jeep feel like a totally different beast.
When putting your foot in a motorway speed, its no longer 'come on come on come on', now its whoahhhhh and hang on and I'll be honest ..... I couldnt stop grinning and giggling.
Now I'm not expecting to see much (any ) saving in fuel driving like that, but its sure a blast now and makes the Jeep a bit of a sleeper.
I have no complaints about throttle sensitivity, and lag is massively reduced.
I always liked my Jeep, but was a bit ho hum, but now I LOVE my Jeep.

I also ordered my GDE Eco tune today. We had a 100,00 mile extended warranty on the Jeep and it is finally over. Hope to add the DPF delete down the road.

Keith got me to try out a new eco tune. I lasted 3 days before I put the hot tune back on. It's the only way to roll!

Did you notice much fuel economy difference between the 2 tunes?

Nope, but but i would assume that's because my drive is predominantly fast single roads, dual carriageways etc, which is why I favour the extra punch of the hot tune over a possible 1 to 1.5 mpg improvement on city driving.

What do you mean "new eco tune." Is it possible that I have an old eco tune. Do I need an update?

My UK commander had startup idle issues to the extent the ETC lit up, surging on cruise and where I was expecting more diesel noise it was quiet, machine gun noise, quiet. Wasn't really happy. As it happened Keith made up a hot tune for me which is what I always wanted, but he's gone back to successfully sort out the eco, so it idles evenly and the extra noise is now graduated. If you don't have these problems I'd expect you are all good. Ultimately came down to different firmware even on same year same model jeeps I would assume in different territories.

I waited until 113k miles when my extended ended (actually it ended at 115k miles but couldn't wait as I was getting DPF clogged code so needed to do something). GDE added with DPF delete and I would highly recommend getting the delete as it will pay for itself with slightly better mpg and cheaper oil changes (no longer have to use 229.51 oil). Another thing is you can sell your the removed DPF for good money as well (or take it out and knock out the filter itself if you have visual inspections in the state).
