Same here with my light tune EVO 8.never go over 23 MPG even high way only.

 

^^^^ this


my info screen says 32MPG regularly when i drive 25 miles to work @72MPH but it's literally all down hill


My eco is usually around 21 - 23 MPG for full tank averages. Mixed driving hwy, city, up mountain and down mountain w/ the occasional bursts of acceleration to keep things interesting

 

That's why you're getting 32mpg

 

I did. I did the math. The mileage was more or less accurate. I even filled up the tank in Fayetteville and again when getting back to Durham, almost immediately. The difference was almost EXACTLY 3 gallons. That equates to ABOUT 31 or so MPG. The speed limit is also 70 mph, and I tend to drive 5 miles above the speed limit. I have no reason to believe that the HID was incorrect. The trip computer was reset after the tune and checked after arriving in Durham.

Believe what you want, but I get good mileage. A lot of it is how you drive, though. I remember watching an episode of Top Gear in which Hammond, May, and Clarkson all drove from France back to England on a single tank of gas. E85 is a different story, though.

 

I may not be a good indicator of expected MPG, because I have only measured the full tank average a handful of times. In that case, Bryan is right. I only ever measure consumption when traveling back and forth from school (gives me something to do). It is an 8 hour trip. When the traffic backs up, and I have to slow down, which is the norm, I get ABOUT 25 MPG over the course of the tank. I base that on how much gas the car actually takes when I fill up, but the tank does have a nasty habit of clicking the pump off prematurely. I have to hold the freaking nozzle in just the right spot, or it doesn't work. This is exacerbated in the winter.

 

Usually get around 21-23mpg with city driving (light traffic)
27-29mpg on highway.

And in heavy traffic? I'm counting my pennies at that point.

 

22mpg city/hwy mix.

The RA should/will get better hwy milage than the EVO solely because of the 5th and 6th gear ratios.

 

I watch the 'HID' on my 21 mile commute to track my mileage and I watch the average go from the high teens at the start to around 25/26 when I get to work. Same thing on the way home. But my 'real' mpg based on trip odometer/gallons purchased is only 22.37 after 6 fill-ups. So yeah, I think the car's mpg computer is a little on the optimistic side.

 

It's geared lower then the Evo MR in 5th and 6th

 

I am looking into going the GTS or Cobb tune rout. I have a long drive to work so MPG is a big deal and will factor into my discussion. Can anyone report on the MPG gains after tuning with each of these. I know Cobb has an Eco tune also but I have heard it doesn't make much difference over the stage 1.

 

Here's when I started out on my trip from Rockford to Chicago:


And as I neared the exit ramp ~70 miles later:


Not bad for a 12 second car on the highway eh?

Full-tank mixed driving, including some "spirited" driving, shows around 25 on average, so I'm very pleased personally.

 

^^^^^^^^^^^^^
send me your fuel map please jajajajaj(joke)

 

Guys, you do know the HUD is a average right? You cannot use that to gauge short 70 mile trips like that.

I saw 35mpg on my HUD, on E85, for 60 miles. Does that mean I get 35mpg on E85? No.

I'm going to drive down a hill, off the gas and reset the HUD MPG gauge at the beginning and show you guys I get 55mpg.

That would be hella tight yO!

Seriously, stop posting up HUD MPG averages over short distances and start doing the real full tank average math.

Like this:



207.5 miles driven, on 11.331 gallons of E85 = 18.31mpg

K thanx bye.
