2024 DTE
I’ve tried Forscan and haven’t had any luck just like everyone else on this forum after upgrading to a larger fuel tank. I’ve talked to ZooDad annd a few other members and everyone still says nothing has surfaced yet as far as calibrating the DTE to be correct. Yesterday I spoke with S&B and they have a tool being released in the next couple weeks to calibrate for there specific tank sizes. I called Titan Tanks after being that is the brand I have and they have no such tool in the making….but the tech guaranteed me that Forscan can adjust it on the PCM without a doubt. Apparently he has done it multiple times on multiple trucks of the newer years. Has anyone had any luck yet or is he crazy?

Titan has continues to say it can be done.
It cannot be done with ForScan by any known method.

I pretty much got the same story from Titan. I decided to wait for S&B before I upgrade my tank but God, I wish somebody would call Titan out and tell them to put up or shut up and put them on blast when they can't. They say they can just to sell the tanks and when the DTE doesn't function I am sure they have a line where they say it should and must be something different with "your" rig versus "ALL" the others they have done that have worked.

Hi, on my 2025 F350 6.7L TTD I upgraded my stock 34Gal tank to Titan 55Gal tank. I just used Forscan to change the tank size in the PCM module from 34 to 55 gal. Nothing else needed. The change didn't take effect on the DTE immediately after this PCM change. But after about 4 hours later the DTE data has changed to more realistic numbers. Went from 360miles DTE at about half full tank to 880miles on full tank. My guess is after changing the PCM tank size, it takes a while for the system to update the DTE data.

I finally got around to updating the fuel tank size this weekend. Pretty easy once I figured out I was in the wrong place in Forscan. I was in the IPC and found a fuel tank size, but it was set on "0.0". Finally dug around and found the setting in PCM. Added about 200 miles to empty changing to the 48 gallon setting. Just curious, what is the settings in IPC for?

I wonder if thats for correcting MPG. I know you can get into engineering mode and adjust MPG there. I did it on my F350 and its within 3% now.

Might just be a tune parameter
Just like tire size, the fuel tank size has a capped range limit at 48 gallons?
that would explain why mine only shows 1430 km (893 miles for the math impaired)
