MPG updates

Wont be an issue for him, he has just bought a CRD and all the gear is being transferred.

I wont mention that i got 10.1 l/100km (24mpg) average over the last 2 trips, including offroad use. Ooops, just did. Just doesnt sound as good as a Hemi does under load up a nice long hill.........

Hello Dave, I bought my WK CRD used and with quite a few miles, but never got better than ~17 average hand calculated (EVIC shows 15.4 - 16), though I use it mostly for commuting now, so it is city driving. What kind of mileage did you get before the GDE tune? Is this hand calculated or EVIC? Did you do any corrections after getting the larger tires, etc? If so, what tool did you use? I have never heard that good an average, even from other CRD guys in the states. Do you think the diesel formulation is somehow different down under as well? Thanks.

I don't wanna speak for Dave but I don't think he has a DPF either. As far as tire size correction goes, I think you can get a Hypertech tire re programmer and also I think the AEV EGR (From the Superlift, but you can also buy separately) can reprogram tire sizes as well as ESC for larger tires.

Correct, in Australia, they came with one from 2010 on. I will look into those programmers.
Edit: Hypertech does not list it for the CRD engine, and I know I saw the AEV on their site before, but can't find it now under WK stuff.

Correct, I have no DPF, and use the AEV EGR module for tyre size calibration. My mileage was always pretty good, but even the change to a 265/70 will throw the calculations off.

As a comparison, Stu's WH with a 3" exhaust, no snorkel and only rock rails only gets an average of 12l/100km, but it also rarely sees 100km/h, doing the school and shopping runs. Wherever I go i have to travel at least an hour by highway so thats also a factor.

It doesn't count if your tires are smaller then 20 inches tall.. Lol

I could be wrong but I think they make a programmer just for tire re programming. Not engine specific but I might be wrong.

I know SuperChips does not work on the CRD models at all, even for tyre change size, so check before you buy!
