Mileage:
Manual: 26/34 -> 27/37
Auto: 26/32 -> 27/34
ST: 22/31 -> 22/32

Power/torque:
20: 136hp@6000, 133lb.ft@4500 -> 136lb.ft@4250

“The Focus engine was originally calibrated for emissions,” says Nicholas Schubeck, supervisor, Powertrain Calibration for Ford Motor Company. “We noticed during testing that we could get a lot better fuel mileage by making some adjustments to the calibration while still meeting emissions.”

The team increased the engine’s spark and revised the exhaust-gas recirculation and intake manifold runner control (IMRC) schedules. The IMRC is a device on the intake manifold that increases the velocity of the air going into the cylinder at low speeds. Increasing air velocity helps in the proper air-fuel ratios.

“The issue is that the system also creates a lot of pumping losses, which reduce fuel mileage,” says Schubeck. “By opening up the IMRC a lot earlier to reduce pumping losses, fuel mileage was increased.”

This change, along with tire improvements, accounted for a 3-mile-per-gallon improvement on the EPA highway fuel economy label for five-speed manual models, which now see 27 mpg in the city, 37 mpg on the highway. The 2.0-liter automatic delivers 27 mpg in the city, 34 mpg on the highway. For 2007, the base Focus models come equipped with 14-inch Hankook tires that offer better rolling resistance than the 2006 model.

Schubeck says customers will also notice an enhancement in performance. The extra engine spark improves acceleration, and the refinements to the engine have eliminated the hesitation that normally occurs when the air conditioning is is in operation.

 

No response yet. Tsk Tsk.

 

"The engine had really been calibrated for emissions instead of fuel economy," said Nicholas Schubeck, supervisor of powertrain calibration for Ford.
it.

and i said that a few weeks ago on fanatics and no one belived me.

 

I thought everyone knew it was tuned for emissions over economy? Hanging revs like it does certainly doesn't save fuel.

 

then added that under front black shield and picked up .5 to 1 mpg from that.

What? what is that? can you please explain.

 

Would this also apply to 05 model? I have to believe it's the exact same engine.

 

does ford cahrge to retune the 06 focus to get better gas milage?

 

Nobody asked their dealership yet?!

 

Yes i have asked my dealership. It seems he got the programming necessary. They were going to charge $100 for the reflash. So now it s time to start dealer shopping.

That sucks. I'll be going for my (first) oil change in a few days. Let's see how much they want to rip off.

Shouldn't such updates be FREE?!

I don't think I'll save $100 gas in 5 years! :thumbdown

 

I just phoned the dealership to ask in advance, but they claimed they know nothing about it. They also said there should either be something wrong with the car, or there must be a recall. None of these hold for this case. :dunno:
Anybody know what category this falls into? or a TSB number or something?

 

you guys just dont know how to talk to the service dept. just my 2 cents

Well, personally I have only talked to service departments in dealerships 3 times. So yes, it could be that. But your post wasn't exactly helpful either

 

I know wasnt it.. In a smart ass mood.

 

As soon as i get some info on the reflash, I will post it.

 

Or you can call Bill Park at Prestige Ford in TX. He should have the info, or email. 972-864-3673. Just tell him you are in Michigan and you wanted to know a TSB or something you can tell your service department.

 

Any new updates, or even ideas on how to ask/convince the service department? I'm going for my 5000 mile service this evening.

Thanks,
Ahmad

 

It won't be a recall but it should be a service bulletin (in other words, if you are still under warrenty they should give it to you if you request it). You can easily make this case by complaining about the gas mileage.

 

Weathetr You Ask Yor Dealership On The Retune Or The X Cal. Which Of The 2 Would Be Better?

 

I went for the 5000 mile service today ($75, ouch!), but they claimed there was no related TSB. They even gave me a printout containing 2 unrelated TSBs, and claimed this was all the TSBs for my car and since it was done online it's up-to-date.

 

I just had this done on monday. Didnt cost anything, and i noticed they wrote it up as complaint about fuel economy.

The receipt i got says this
"poor fuel mileage
test EEC. Test fuel pressure. no codes. monitor pid and call hotline, program PCM and retest"

To soon to tell if i will actually get an increase. If they are giving you a hard time about it.. just take it in and complain about the fuel economy.. and maybe casually mention that you read something about an update..

 

I just had this done on monday.

BTW do you feel any noticeable change in the engine? response, hanging on to revs, etc...

 

the rpm doesnt seem to hang as long

 

I know my 07 5 speed sedan gets great milage, I have gotten over 400 miles to the tank.
A lot better than my automajic wagon
