Tboneguy Posted July 30, 2008 Report Share Posted July 30, 2008 I noticed that on fueleconomy.gov the even heavier 09 FWD Flex has a rating of 17 City - 24 Hwy, and the 09 Edge Order Guide shows it's also rated at 17 City - 24 Hwy. I know it's no huge difference, but my 08 FWD Edge is rated 16 City - 24 Hwy. Do you think they've done some tweaking to the programming that they'll pass down to previous years via a Reflash? 2009FordEdgeOrderGuide.pdf Quote Link to comment Share on other sites More sharing options...

Wondering if I can make the same change on mine. Quote Link to comment Share on other sites More sharing options...
kdd01 Posted January 19, 2009 Report Share Posted January 19, 2009 (edited) Have an 08 with AWD, 5/08 build date. Averages 17 MPG, that is mixed back roads and highway. Not much better than my F150 with 15.5 MPG. Edited January 19, 2009 by kdd01 Quote Link to comment Share on other sites More sharing options...
Loosecannon Posted February 16, 2009 Report Share Posted February 16, 2009 I average high 17 or low 18 MPG. Even when i try to drive like an old lady (which is rarely). I tend to drive with the OD off most of the time, otherwise the Edge is constantly downshifting to try and find power. I believe the Edge's are geared horribly. -Cannon Quote Link to comment Share on other sites More sharing options...

Unless the "most of the time" you are driving around with the O/D off is on long downhill stretches of road, driving around town at less than 40-45 mph or while constantly towing a trailer, driving around with the O/D off is hurting your fuel mileage, not helping it. In the long run, it is also putting added/unnecessary wear on your transmission/powertrain. This is a copy and paste from your Owners Manual concerning what happens when you turn off Overdrive: • Transaxle operates in gears one through five. • Provides engine braking. Depending on conditions the transaxle will automatically downshift to increase the level of engine braking while descending grades. • Use when driving conditions cause excessive shifting from O/D to other gears. Examples: hilly terrain, mountainous areas and when engine braking is required. Essentially, what you "think" is keeping your Edge from "...constantly downshifting to try and find power" is fooling your Edge into thinking you need engine braking (like on a long downhill stretch of mountainous road) and keeping it in an unnecessarily low gear. The purpose of a six speed transmission is to allow a vehicles powertrain (engine/transmission) to choose a proper gear suited to the drivers throttle inputs. A six speed transmission should shift up and down more than an older four speed transmission. It is more efficient that way, and keeps the engine in its most efficient power band, both for power and fuel economy. When your transmission is upshifting and downshifting, it is performing as it should. However, you are making the job harder and lowering your fuel economy by turning off the Overdrive function. Of course, it is a free country and you can do as you please. I am simply providing the information to try and help. Do yourself a big favor and read the Owners Manual, especially the sections concerning the Transmission and Overdrive. It will verify the information I have provided. It will also help you increase your fuel mileage and extend the life of your transmission. Good luck. :beerchug: Edited February 16, 2009 by bbf2530 Quote Link to comment Share on other sites More sharing options...
akirby Posted February 16, 2009 Report Share Posted February 16, 2009 I think LooseCannon is simply driving with a heavy right foot which causes a lot of downshifts out of 6th gear. Quote Link to comment Share on other sites More sharing options...
KCFlyer Posted February 17, 2009 Report Share Posted February 17, 2009 I thought the EPA made changes to the fuel economy tests for the 2009 model year. I know it affected the EPA estimated mileage of hybrids. I don't think the intention was to be able to compare one model year to another.

bluetexan Posted March 8, 2009 Report Share Posted March 8, 2009 Just get Steeda to aftermarket tune it. http://www.steedaedge.com Quote Link to comment Share on other sites More sharing options...
garyedwardsmith Posted March 8, 2009 Report Share Posted March 8, 2009 (edited) Does this product affect warranty at all? I know it adds 35hp, but what is the increase in fuel economy? I going to be driven to the Seattle area later in the year and would like to get someone to install this for me and tune my Ford Edge. Is there any one that sells and installs in Seattle or Olympia?
