  1. Yes, that is the correct coding after the mistake(50%/100%) was fixed. Values barely visable for me. Mind interpeting? What's the value do you see leaving from a dead stop under light, medium and heavy acceleration or any other time you've noticed a value or lack of?

     

    Light = 10 - 20 %

    Med = ~ 22 %

    Heavy ( not tested) =

     

    All numbers were from straight away accelerations on optimal traction surfaces.

     

    I think once the car went over certain speeds and/or when engine 'loads' were relatively low, '0.0awd' appeared on the Scangauge II.

     

    What does '0.0awd' mean ( do these numbers even apply to the 4WD Fusion)? Zero power/torque to the rear or a steady state with some power to the rear say 15%?

     

    You mentioned that you were able to see about 35% but not 50% for your Escape. Maybe that is why? Another possible reason why you were not seeing the 15% is because your steering wheel was not turned to certain angles in order to engage maximun torque vectoring to the rear.

  2. What's to tune? All that can change if any is the percent of rear wheel torque. The explanation of its operation in the manuals are exactly the same. Distribution of torque from a heavy acceleration start is different, so you may/maynot be able to squeak the tires. If they had two unmarked Fusion's one with AWD(4WD) and one without, I dare say that you couldn't tell the difference under normal driving conditions.

     

    The situations where you'd expect it to help after reading the sales brochure are pure hype. I or anybody else doesn't need 4WD(AWD) on dry hard pavement in the middle of June, yet it does it costing some MPG. I and others have been mislead by Ford's marketing of so-called Intelligent 4WD(AWD) which really isn't very intelligent at all from what I've seen.

     

    You're right. The car is not intelligent ... Mr. Newton is. It's all about physics:

  3. There once was a selectable graphic showing the Fusion AWD under different driving conditions. One showed a winding road with torque shifting to wheels side to side. Ford pulled that link. Why? It doesn't work that way. It "only" shifts torque from back to front not side to side. There is a electro-mechanical clutch in the rearend and that's it! AWD is a misused term, it's really just a variation of 4WD and would better to call it Automatic Four Wheel Drive or A4WD.

     

    I have a '09 Escape which is the same system. I monitor the rear wheel torque all the time. Every time you leave from a dead stop you get rear wheel torque which slowly decreases till you reach a constant speed. Ford claims increased torque under heavy acceleration. All the way to the floor from a dead stop, never more than maybe 34%. In theory one should get 50% max. Even light acceleration shows 20-25%. I've tried to force increased rear wheel torque on snow at low speeds and never seen any extra. Seems to be more hype than fact to me. I intend to try more again on snow this winter.

     

    The Acura SH-AWD has a clutch pack at each rear wheel which makes it a true FWD biased AWD: My link

     

    Think of the Fusion 4WD version as OEM/factory pre-tuned for 'performance'. For example, below is the aftermarket performance tuned 'Haldex' for the VW R32 and Audi TT Quattro:

     

    http://www.hpamotorsports.com/haldex.htm

     

    Btw, the 4WD Fusion's Traction Control is really a form of brake lock differential (up to 62 mph for both axles). Technically, the 4WD Fusion can divert certain amount of torque (how much and how aggressive?) to any one wheel.

  4. Agreed, it's always ON but if you read the description of the so-called On-Demand System outlined by Ford's Ashok Rodrigues, he states that it's FWD vehicle till front wheel slippage is detected then it sends rear wheel torque. That's incorrect as even the Ford Workshop Manual states in a vague way by wording it that "most" of the torque is directed to the front under normal driving conditions. This would mean that "some" torque is sent to the rear wheels under normal driving conditions.

     

    1, He is wrong.

     

    2, He is just trying to sell cars (there are many potential customers that prefer the old 'slip and grab' when needed type 'AWD' to save gas and wears).

  5. Back up a minute. With all this monitoring of throttle, steering angle, wheel speed, etc., why does it send rear wheel torque on dry hard pavement? The sales hype leads one to think that it doesn't like a on-demand 4WD system or only when needed. Where's the need on light throttle while driving straight on dry pavement?

     

    The reason why Ford used the 4WD Fusion in the two Fusion/Ford challenges against the Camery and the Accord on 'dry hard pavement'.

     

    The 4WD is always on (unless the handbrake is engaged I think) so that front to rear vectoring responses are quick and smooth.

  6. This is not true when mentioned "If you purchased your car new and do not receive a letter it means that your car does not have any of the questionable valve stems" I did not receive the letter and yet did get a flat tire with valve stem being the cause and had to pay 32.67 for repair....although I did receive the "alert" letter after that (probably when my work order sheet went into Ford Co.)..I was also told at the time of repair I would see 3 more tires go flat......My 2007 Fusion is now in being repaired for the 2nd flat tire...same cause....I was told now Ford would pay for the 2nd one (and probably next ones should I be so unlucky)but not the 1st. hmmmmmm I wonder why next ones they will pay for but no reimbursement for the 1st...sounds like to me there should be a recall and reimbursement for the 1st one. After all this is not the consumers fault who had bought new....questionable about where valve stems were made as well. This is definitely a safety issue and Ford should be responsible for all costs...that is my opinion

     

     

    Since the tire valve stems are not excluded from the 36 000 miles "bumper-to-bumper" warranty, you should not be charged for your first flat repair if the car has not been driven more than 36 000 miles. If you were charged for a supposedly warranty repair job, it implies user abuse!

  7. Ours did the clickity-click when cold on hard turns under power, Ours get run hard and put away Wet when I drive it and when Stephanie does she is "good to it" although but the tire wear on the edges I know she pushes it LOL

     

    AWESOME CAR!! Buy one!

     

     

    EDIT: Ours is a 2007 SEL AWD 45,000

     

    The issue you are having with the car may (very likely!) fall under TSB 07-18-6 SEPTEMBER 2007 Drivetrain - Front Axle Clicking/Ratcheting Noises ( replace front CV shafts). Ford Fusion TSB 07-18-6 should be covered under the 2007 Powertrain Coverage ( 5 years or 60 000 miles, whichever occurs first for all 2007 Fusion/Milan models).

  8. The Fusion is one of the best-kept secrets among the throngs of midsize sedans on the road. Built on a solid platform shared with the previous-generation Mazda6, it has the distinct advantage of all-wheel drive over its distant cousin. Sharp, linear steering feel and a good driving position, combined with stable and balanced handling in all conditions, are dominant traits. The Fusion even has quadruple windshield washer nozzles for the nastiest bits. Power is delivered by an unremarkable 3.0-liter 221-horsepower V6 engine, thankfully redeemed by a good 6-speed automatic gearbox. Environmental Protection Agency fuel-economy ratings are 17 mpg city and 25 mpg highway.

  9. ...With the T/C off, I had a small drift to the left, and then to the right, so I do not know what that is about. It felt like my Grand Marquis, but if it's open, it should not do that.

     

    Here is another question, with the T/C off, is the T/C system logic still being used for the AWD system?...

     

     

    When the AWD Traction Control is turned off, it is possible that only the throttle control is disengaged.

     

    Here is an example from Jeep:

    http://www.jstage.jst.go.jp/article/trol/2/1/19/_pdf (look under "Vehicle Technology")

     

     

    The Fusion/Milan/MKZ AWD system(2007-2009) does not use "Viscous Coupling", it uses "Electronic Clutch (or electronically activated hydraulic clutch)" and it's AWD Traction Control is similar to "EDL (often referred to as Electronic Traction Control.)" with throttle control.

  11. Well my post of February 2nd was ok back then, however now at 30,000 miles, my POWER TRANSFER UNIT (PTU) (Transfer Case) is leaking. Started with oil showing up on the floor of my garage. Took it to my local Ford dealer, and they thought it was the seal that comes out of the transfer case, and they replaced the seal, however it is still leaking and it is not coming from the new seal.

    Have another appointment on Monday January 5th, with the L/M Dealer that I purchased the car from. Problem in Florida is that there are so few AWD's, that I don't think anyone knows how to fix them. In reading my Owners Manual, it says that the PTU takes 12 oz of a Special Synthetic Oil, and I hope that I have not lost it, but I will let the L/M Techs look, and they can keep the car while they give me a loaner.

     

    They have not looked at it yet, however because the oil is NOT red, I know it is not Transmission Fluid, and it is too thick to be Engine Oil, so the PTU is the only other thing in the area that it could be.

  12. Hi,

     

    This is the second winter for my 2008 Fusion and I continue to have problems with my electric windows freezing up (will not roll down because of the cold) when the temp gets below 20 deg F.

     

    It's been two days now - if it don't get warmer soon I'll probably have to go to the local car wash to defrost them! ;-)

     

    Anyone else have this issue?

     

     

     

    thanks

     

    Jeff

     

     

    I think it's the frozen moister/water on the felts surrounding the window that is causing this. Set the Climate Controls to hot and defrost ( all the way to the right). Once the engine/heater warms up, set the fan control to level 3 or 4. It takes about 5-10 minutes before I was able to roll down the frozen front window(s).

  13. About the 05-08 Fusion chassis:

     

    "A satisfying ride and rewarding handling begin with a stiff chassis," says Ford, thanks to a torsional rigidity that is 12.7% higher than on the base architecture (the Mazda6). "The Fusion's steering is responsive and agile," says Brian Vought, Fusion's chief engineer

     

    http://www.cartest.ca/2006_ford_fusion.htm

     

     

    ...chief engineer Brian Vought acknowledges that 40 percent of the Mazda 6's chassis is carried over with minimal changes. That's great news, because the 6 was born under the zoom-zoom sign, and Mazda engineers willingly pointed out their car's weaknesses so that Ford could fix them.

     

    Stretching the 6's width and wheelbase by 2.1 inches and its length by 3.4 inches spotted the Fusion in the upper half of the mid-size segment, where the Accord, the Nissan Altima, and the Toyota Camry live. Ford raised structural stiffness by 10 percent, ...

  14. Is this good? forgive me, but i failed the conversion charts in high school. Anyhow, we just bought an 09 SE V6, lowest we have averaged 18.5(in the city). The highest was 29.6. We have 565 miles on our car.

     

    9 L/ 100 Km (26.13 Mpg) is very good for a V6 SEL( the SEL's stock tire/wheel are about 10% wider and about 3-4 lbs heavier per tire/wheel than the SE's stock tire/wheel). Your numbers are very good as well.

     

    There are a number of conditions/things that can impact your gas mileage not just "city" or "highway" driving . For example, % of ethanol in the gas, wind, terrain, stop and go, idling, tire pressure, temperature, traction, weight and etc.
