Dodge Gas Evolution - 2007 Dodge Ram 1500 5.7L Hemi

what is this does it realy save gas?

 

Are you refering to the MDS??

 

yes, what does it do?

 

basically if your traveling on the highway for instance...at a steady speed. the hemi goes down to 4 cyclinders to help save on gas...you will probably notice when it does because it sounds like crap...but if you think about it...it will sound like a big truck like the ram driving on 4 cyclinders

 

You can get 22 mpg in the hemi cruising at 55-60 mph on flat terrain. I only use my truck for commutes to work and my overhead is almost 20mpg running total for the last 3 tanks. I get about 440 mi from 22 gal fillup.

 

you know your tank is a 26 gal tank right and not 22... just curious if your filling it up all the way when its pretty close to empty or not. Because if you are, your not getting the mileage that you think you are. The overhead is not accurate especially when you dont reset it at every tankful.

 

I write down everything. The pump usually clicks off at around 22 or 23 gal. I find the overhead is accurate.

 

Hmmm. I have MDS. If im on the highway I get about 20 if im doing city driving its about 13.5-14

 

makes me wanna cry with my 05 and 36 gallon tank

 

anyone having hesitation / sputtering problems with thier MDS systems?

mine was sputtering off the line (not floring it) as well as around 40-45mphat cruiseso i took her in to the shop. they "reset" the computer. Now my blue tooth doesnt work and it still sputters now at 45-50 mph cruise. it doesnt happen when i accelerate through those speeds but it does with or with out the cruise control on, and only around 45-50 mph...
