Factory ECU values for Triton V10 6.8 F53 2004

[Pasque]

Hi,
I'm located in France and I'm owner of a 338SE with Ford Triton 6.8 F53 2004 engine.

It has been programmed here in France by the previous owner to be Flexfuel compatible.

I have excessive fuel consumption and I'm trying to check with a french specialized company if the ECU values are correct.

I'm looking for the factory ECU value for this model.

Is there someone who have these informations or who can give me information to get them.

Thank you

I cannot help you but I'm wondering what "excessive" means?

Our 2019 V10 gets about 6 miles per gallon which seems to be about 2.55 kilometers per liter.

We have the 6-speed transmission and it looks like you have the 4-speed transmission which may affect your mileage. We have the 22,000 pound GVWR chassis.

Hi,

It makes 5.88 MPG without pulling anything

I have a post openned with this subject lower.

Compared to other owner, it seems very high.

This is why I'm trying to optimize the ECU with a specialist

If you are using FLEXFUEL.... I know here in the States FLEXFUEL doesn't get as good of MPG's. Not sure if that's true in France? I was told about 20% less. Who knows if that is accurate? Safe Travels

Yeah. Flex fuel is know to give drivers less miles per gallon.

In general Ford’s Triton V-10 engines are known to consume a lot of fuel even in the pickup trucks they are in. I would suggest possibly replacing the spark plugs, clean the MAF sensor with MAF cleaner, check air filter, check for any oxygen sensor codes or just replace those to.

Perhaps you can get in touch with a local car tuner/dyno tuner who knows Ford motors and they can check your fuel trims and such.

I know here in the states. Some car tuners will do remote tuning and trouble shooting with customers and their vehicles. But it is a bit more cumbersome that way.

Perhaps contacting 5 Star Tuning. They have been around for quite some time and do custom tunes and such. Maybe they can help you or point you in another direction. I’m thinking of using them for my F350 truck myself for a bit more power and transmission tuning.

In the USA Flex Fuel is also known as E85, 85% ethanol and 15% gas.

Our 2019 V10 is not approved for E85, just up to and including 15% ethanol (E15).

But the Onan generator is only approved for up to 10% ethanol or E10. Since the engine and generator are fed from the same fuel tank that effectively limits us to E10.

The mileage decrease with E15 is supposed to be large, as others noted so I'd never use it unless I absolutely had to.


Another issue for Pasque is that I think he has the 2-valve V10. I think the current 3-valve version came out with the 2005 F53 chassis.

5 Star Tune is a good suggestion. They should know.

Today I can respond because I had our MH out of the garage this morning but, unfortunately, I could find nothing on my Innova 5610 scanner about Flex Fuel. I looked at all the data shown with just the key turned on as well as live data with the engine running. Since I am not yet an expert with this very capable scanner I finally just went to each data value looking for the word Flex fuel or anything about ethanol or fuel mixtures. All dead ends, I'm afraid.
Our V-10 is a two valve model from 2009 and is not rated for E85 as far as I know. Sorry I couldn't be of more help.
I do know from watching Scotty Kilmer's YouTube channel that Flex fuel ECU's are made to detect which fuel in being used and to change necessary switches when it detects something different. I think if mine was setup for Flex fuel all those settings would show up with the possibility of changing things manually to see how the engine responded. But I cannot say that for fact.
