@CP07;Hi Guys. i just joined but had my commander, 3.0 limited, for a year now great drive - very thirsty though.
Diesel here, at the moment is about £1.25 per litre (i cant work that back into us gallons and dollars).
mine was averaging 19 MPG on very much city mileage, around 32MPG if i stuck to a steady 56MPH on motorways upto recently. I had it remapped, with the EGR left in situ but mapped out. im now getting about 23MPG on the same city runs, but if i go a little bit nearer 70MPH im getting nearer 35MPG.
I just read on another board of someone having a 2.7 cherokee remapped and now getting nearer 40mpg on motorway runs but also having replaced his fuel pump.
We've had some good times with the commander though (regardless of it drinking fuel) taking the grand kids to the coast with loads of essentials. In the snow, or what we class as snow - i.e. probably nothing like you guys get, it was very impresive.
having the usual radio/sat nav/ screen issue, it works sometimes but not most of the time. ive had it looked at and the general theory is that its something to do with the video card rather than a power problem. im still trying to source avideo card, screens are being quoted here at £400, replacement Pioneer unit with similar features at £1000. Ill stick to using a garmin as a satnav for now. the MP3 disc player is awesome though so im in no rush to change out an otherwise great unit.
Only problem at the moment is the indicator multifunction switch - again a fairly common fault. A mate on another forum has one from a Grand Cherokee with the same part number so I getting that one from him.
The other weird thing was decoding the VIN through the Jeep oficial site - mines a grand cherokee seemingly, but its badged as a commander, looks like one, drinks fuel like one and has 7 seats - so whatever jeep do on build sheets is just weird.
ThanksI would be ecstatic to have that mileage!! Welcome to the forum!
What exactly are you referring to when you say that you had it re-mapped?
I've never heard that terminology before.
I've also never heard of a Commander's VIN being run through FCA's website and coming back as a Grand Cherokee - that is extremely unusual. I'd say follow the steps below on the link provided and see if you get the same results stating that it's a Grand Cherokee:
To get the factory build sheet for your Commander, click on the link below and navigate to "Your Vehicle" click on "Equipment Listing" and then enter your VIN number in the box that says "VIN" and hit "Search". The factory build sheet will list all of the factory options & optional preferred equipment packages that your vehicle had installed from the factory when it was built.
Sounds similar to what we do over here with the Superchips flashpaq programmers, basically reprogramming the ECU with high performance settings.the remapping is probably called something else on your side of the pond -have a look at
i cant post links so have a look at celtictuning.co.uk
basically a techie type plugs a laptop into the OBD port and changes loads of software settings - mine pre remap idled at 800RPM after the remap it idles at 500 and accelerates like the wind (ok, a 2 ton not aerodynic wind) so on idle speed alone a fuel saving.
forgot to mention another repair i did using a straw from the burger chain with the upside down W logo, draining the passenger footwell when the rubber bung thing got blocked, so i cut the end off and replaced it with the straw.
Tried it on 2 different websites, one was a Jeep specific site and the other was an FCA site & no luck, I guess the European VINS must be contained in a different database, seperate from the U.S. VINS.I tried it but it wouldn't recognise the VIN, maybe because its a European spec?
if you want to run it through any other site, try useing 1J8H1E8MX6Y1173855 as a sample VIN.
Believe me its had a fair few people who I would call Jeep experts (certainly they know a lot more than me about Jeeps in general) scratching their heads aswell over here. some of the commanders When the owners have checked the VINs have come back as Commanders rather thann GC's.The model coming back as a Grand Cherokee is strange; it puzzles me why they don't make the distinction between Grand Cherokee & Commander - but the series (XK) is obviously correct.
Still seems odd though.
Happy to help @doesgo, that's why I'm here.I'd love to have that fuel mileage! I'm getting somewhere around 12 MPG in the city and 17.5 MPG on the highway. Heavy truck with a big engine will do that, though. And we're blessed with $2.65/gallon gasoline (for now), too, which makes it much more palatable (just under four liters per gallon).
Thanks a lot for posting that link to the build sheets, @Big Blue! Great thing to have.
