if you keep the MAF in its stock housing and in about the same location as stock, it should be fine. but, if you do get a CEL, put the stock intake back on, reset the computer, and you should be good to go.

How does one reset the computer in these things? I knew how to do it in my F150, but not in this one.

It shouldnt even take that long. I would say at least 2 mins.

I am a newbie to computer tuning and the owner of an '07 Fusion SEL AWD. Are you saying that if a PCM or TCM is adjusted (programmed, flashed, recalibrated, whatever) that it will revert to default or the factory setting if the battery terminals are disconnected for 10 minutes or so? We are only getting 13.2 mpg in town, babying this thing for the first 500 miles. Dealer says bring it in at 1,500 miles and they will "check the computer." Is it likely, in your honest opnion , that they will be able to improve the mileage or is it more likely that I am being fed a line to pacify me? The dealer is reputable. At this stage of my life I am more interested in mpg than I am 0-60.

Resetting the battery will revert it to the base parameters of the tune you are running. It may or may not help in your case. What will probably happen is the dealership will hopefully find a newer calibration to use on your car and reflash it. Many guys who have had that done on this site said that it seemed to clear up most of their problems, hopefully it will help with yours.

Bob,
Thank you for taking the time to reply. I feel as though I have learned alot from this forum and posters like yourself. It better equips me to converse intelligently with the dealer, who has always been helpful in the past with our 2000 Focus. As I stated, our SEL V6 AWD only has 500 miles on it and is still breaking in but I sure don't want to be stuck with 13.2 mpg for city driving since that is 90 percent of our driving situation. I realize now that the AWD decision was a hasty one, but partly based on the safety and handling factor.
That being said, I still believe the 19 mpg EPA estimate (range of 16 to 22) should be obtainable with the proper computer tuning. We are not "zoom-zoom" drivers and live where the terrain is as flat as a pool table, on the Eastern Shore of Maryland. The highest "altitude" for miles around is 50 feet above sea level.
This machine, as equipped, had a MSRP of $27,105 and you can buy alot of rice burners for that price. I honestly will not keep the Fusion -- as much as we love it -- if 13.2 is the best that it is going to do under city driving conditions. I'm also one of those people who hates to spend a lot of bucks on a brand new vehicle.
Even so, I am willing to get this situation some time for improvement.
If I understand your words -- Resetting the battery will revert it to the base parameters of the tune you are running. It may or may not help in your case. What will probably happen is the dealership will hopefully find a newer calibration to use on your car and reflash it -- correctly, once the computer has been reflashed those calibrations then become the default. Is that correct? Resetting the battery takes the computer back to its most-recent flash, not some sort of factory default?

Resetting the battery just resets what the computer has learned so far. In your case, it may not be a bad idea to see if your mileage will improve. Resetting wont CHANGE any of the base parameters.
What the dealer MAY do is change the file completely to a revised one. Its common, on new model vehicles, that Ford will revise their own programming, based on feedback from consumers such as yourself. If there is a new file available from your dealer, they will surely install it, but it is not like resetting your battery, they can actually change your base parameters.
If you have more questions, feel free to ask!!

Bob,
Thank you for your intelligent replies. Yeah, like most people on forums, I am guilty of thread drift. I am really looking for people with V6 AWD and their mileage experiences, specifically what can be done to improve it. I will start a new thread. Again, thank you for taking the time to reply. It is much appreciated. Boz
