Miles to empty Question
Does anyone know if Ford has the ability to change the value for the amount of fuel that the computer uses? When I fill up my tank it will only show 490 or so miles to empty. Obviously it does not know about the larger 52 gallon Titan tank and is still using the 28 gallon figure for a full tank. Even better is it something that can be done by Matt with a download on the SCT?

This is just thinking out loud, how would you tell the computer that it has a larger tank to start with? I'm sure anything is possible. Going from the top of my head, the biggest thing available from KTP would have been the 44 gallon that comes with the Excursion. Unless there was something bigger for the F450 & F550 models...though I doubt it.

Thanks. Yes that's along the line that I was thinking. Other trucks must have larger tanks.44 would be better than 28.

I agree with bfloyd4445, there at least had to be a way in the not too distant past. My 04 owner's manual list three different fuel tank sizes...though one appears to only have been available under the Excursion (44 gallon).

There is no way for the dealer or consumer to reprogram the PCM on the newer SD for a different size fuel tank. Also a 52 gallon tank was never an option, so this is not even a choice in the PCM strategy.

Think most use EPROM'S for future upgrades. I will email Ford and ask them. They are kinda slow to repond so it may be awhile before I can get back to this thread with there answer.
