Fuel Mileage with Edge Evolution on Extreme

Hey there,

Just curious to know what kind of fuel mileage anybody else here is getting specificly with their edge evolution programmer on extreme mode. I figured more power meant decreased fuel economy, but that seems to most certainly not be the case in my 7.3 Excursion. I bought this 2000 excursion in Utah, and on the trip home to California, the mileage computer said 16.5 mpg, and when I got home I calculated that I was actually getting about 18. A few days after getting it home I installed the K&N Fipk intake, a 4 inch MBRP exhaust system, and the Edge Evolution extreme program, and now the computer consistantly shows better than 24mpg. So I am waiting til I drive a bit more to fill up the tank and check the mileage myself against what the computer says, but I think it's gotta be fairly close. I know that the intake and bigger exhaust are going to increase the fuel economy some, but it seems to have more to do with the programming.

When I loaded the "Towing" program the mileage computer instantly started to drop indicating worse fuel economy. Then loaded extreme back on, and the fuel economy came back up. Seems backwards, but totally awesome if it really is the case. More power and better fuel mileage? Hell, I'll take that any day!

Re: Fuel Mileage with Edge Evolution on Extreme

Sorry to burst your bubble, but if you do a search on this forum for programmers + mpg, you'll find that some of the programmers trick the sensors to provide the fuel rate that they do. In doing this, it pretty much makes the lie-o-meter overhead useless. I think you'll be lucky to see mpg's in the 17 to 18 range, hand calculated, on the Extreme program.
Also, your signature doesn't show if you have oversize tires or not, but if you run oversize tires, and the pcm hasn't been reprogrammed for the correct tire size, you won't get accurate numbers unless you factor that in to your equation.
Not saying that mpg's in the 20's isn't achievable, just stating that unless you drive 55 to 60 mph, you're going to see the mpg figures that most everyone else with a 7.3l sees.

Re: Fuel Mileage with Edge Evolution on Extreme

Hey there, thanks for the reply. Yeah I figured something like that would be the case. I have not been trusting that computer much, wich is why I haven't been getting my hopes up much until I manually check the mileage to see what I'm really getting. It does not have oversize tires at all.......yet.
My signature does not say anything about my ride, because I can not seem to figure out how to edit my sig. I assumed I could change it later so I didn't bother making one when I signed up on this site. Where do I go to edit it?

Re: Fuel Mileage with Edge Evolution on Extreme

Click "my home" in the tool bar second from the top of the page. Then you can edit or set-up your settings.

Your mileage will never match up to the overhead again....too bad!

Re: Fuel Mileage with Edge Evolution on Extreme

I tried the Edge Evolution and it was a lot of fun to drive on "extreme" but it reduced my fuel economy by 2 MPG. I figure my mileage the old-fashioned way and always test over at least four fillups.

I have a 2002 Ford F-250 powerstroke with the evolution and an after market air intake. I also have a 3" lift and 4 wheel drive with AT tires (Normal size tires). I also have a brush guard grill and headache rach Before I upgraded I was getting 15.8 Hwy and 13.5 city. The manufacturer said 2 to 5 mpg on the air intake and 3 to 5 on the evolution. After tweaking the evolution I have exceded those numbers . the onboard meter was showing 38.3 mpg on the highway and 28 in town. I checked for several tanks manually and realized that the onboard meter was not accurate. I was actually getting closer to 28.8 on the highway driving 60 MPH and 23 in the city. I am extremely satisfied. I leave the evolution on extreme because it gets the best MPG. Keep in mind that if you put your foot in it and keep it there the MPG will always suck. Put it on 60 mph cruise control and it does really well. Does anyone know how to recalibrate the onboard MPG sensor so it reads correctly?

I am sorry I did not respond sooner. When I mentioned tweeking I was referring to the custom settings that you can calibrate in the manual. The custom settings are on page 21 of my manual. When you are preparing to program your vehicle, you will have the option to change certain parameters. You will need to chosse yes when promted to " Create a custom program" At that time you will have the opportunity to tweek certain things on the program. I found that lowering the the standard shifting on auto trans to a negative number did the most good in raising the miles per gallon.
