Some of the newer jeep's and other cars have a thing that tells you how many MPG your geting is there any way you can add these to our cherokes?

 

you mean the digital displays that tell what the MPG is? yeah, but the work (i personally feel) isn't really worth it.

 

Yea but they are anywhere from $200-300 and like the poster b4 me said "LOTs" of work...Tj

 

i agree, it isn't worth it to get the digital display for mpg. if you use u're XJ as a DD, then you should be able to gauge exactly how much u're getting per gallon on a every fill up.

 

You can always look for an overhead console from a jeep that came with one with all the sensors, that should work...Tj

 

Very easy if it's OBD2, and relatively cheap.

I've got a scanguage on my Civic, and it's a lot more useful than just MPG. It'll also tell me values of just about every sensor that the ECU reads, will recognize and reset CEL codes, and does some rudimentary datalogging. It's INCREDIBLY helpful in chasing down CELs because you can see the sensor data in realtime while the car is running.

Not bad at all for $159. Unfortunately they only work on OBD2 cars, so I can't use it on my 94 Cherokee. I've never personally tried the scanguage on a Cherokee, but the compatibility list says it will work on every Jeep past 1995 except for some problems on the diesel Liberty.

 

The ScangaugeII can tell you lots of things including MPG, it's pretty easy to install also.

it costs around $170 though

 

Scangauge is supposedly quite accurate, but only works on OBDII. If you've got a newer XJ, go for it.

 

DARN!! I guess my 94 is too old...Tj

 

My Brothers Limited Has it factory There cool but its better not too know lol

 

Dont you guys know math anymore? You really need a machine to do it? However here is something you could use to moniter ur MPG in any vehicle, anytime, ignition on or off.

 

I have a 1995 I am not sure if its ob2 or 1?

 

96 was the OBDII conversion. Sorry

 

I took him to mean he was interested in a real time gauge. My wife's truck has one and I love driving with it.

 

I know I was just bugging. Just out of curiosity, how accurate do you think those things actually are. I dont know, and would like to know, my truck has it
