First fillup after getting the tank installed. I'm very pleased with the new tank.
Transfer Flow 58 gallon replacement tanks are finally being sold and installed!!!!

Happy to report that after a couple fill-ups the Forscan adjustment to the larger tank size looks good. Still no idea why the numbers were not jiving immediately after install/Forscan adjustments, but nevertheless all looks good now. I did adjust the "reserve" amount in Forscan as well, changed it from 6 gallons to 4.
607 miles / 11.0 mpg = 55.2 gallons with ~ 2.8 reserve (or less as I didn't fully top off I quit when the pump auto shut off).
Very happy with it all and all.

Got mine installed a week ago and modified Forscan before the install. I was wondering how long it would take for the change to occur. The miles to empty keeps increasing as I drive. First fillup was 55 gallons. Couldn't be happier, got gas at $2.59/gal. Around here it just went up to $2.99. (Saved a few bucks for now!) Cheers
Good to know. Didn't realize there is a reserve setting that can be change. So the default is 6 gallons?
I'm curious where you can change the reserve? I didn't know that was possible. My truck is still learning, and I am staing right around 725 to e. After the initial forscan change it was pretty low, but has consistently been increasing over the last week since the install.
Can someone in the know explain where in FORSCAN I can find the Mod to change the reserve setting?
There's a DTE Empty Value with a default setting of 6 (assuming gallons) in the IPC Module. I changed it to 4.

What are you guys doing with your original gas tank? Mine is getting installed tomorrow and I don't know whether to keep it as a backup, try to sell it, or just have the installer dispose of it... I know it's considered hazardous waste and would be more difficult to dispose of later on, so i'm tempted to just have the installer get rid of it for me, but at the same time it seems like such a waste since it's basically brand new.
I'm looking to keep mine as a spare gas storage tank. I have multiple places to store it out of the weather. Only thing I am concerned about is the gas smell. I have it in a shed now, and I need to ge back in and see if it reeks of gas. If not, I will keep it and fill it up. If it doesn't work, I will probably burn it. I have 20 acres that I live on.
Sold mine to the local salvage yard. Not worth much but I didn't need it sitting around the shop either.

How much if you don't mind my asking? Just wondering if it's worth the trouble or not.

I don't think that is accurate for our trucks. I checked in the listing for the modules and I do not see anything related to "fuel" or "reserve" in any of the memory addresses. This is using the 2021 F150 spreadsheet for a reference which has been very comparable to our trucks.
There are a lot of items that are listed in Plain English that are essentially not-applicable. I have come to believe it is a global list for all vehicles.
The way to check for sure would be to compare the hexadecimal memory addresses in Forscan before and after that change from the Plain English version of the module and see if anything actually changed...
Installed!!!....The tech with the quick flash had left for the day, by the time I showed them how to put gas in it, so I gotta stop back in and let them flash the computer to change the tank size next time I am on that side of town.
Off to the salvage yard tomorrow to sell them the OEM tank, 2 spare steel wheels, and fill my pockets full of fuses.

I got $7.83 for the skid plate and brackets and $185 bucks for 2 spare steel wheels, made the trip worth it to salvage yard..They wouldn't take the plastic tank so I took to the dump.
Almost $200 bucks for an hour trip, it was worth it to get the stuff out my shop and I got almost enough money for my next 1/2 barrel of IPA for the kegarator...win for me YMMV!
I have found out mine seems to read top heavy. I started around 725, but ended up around 660. Also, when at half a tank, I had a lot more miles to e than I had driven. Doesn't seem balanced.
My readings seem accurate based on larger size after I changed to DTE source from PCM to IPC. I'm guessing that PCM learns, while IPC uses the configured number of gallons + gauge reading.
I did get a paper from TF that told me exactly the numbers at Empty,1/4,1/2,3/4,Full - it's somewhere at home.

One thing I did yesterday after I filled up was calculate my MPG and multiply it by 58 gallons. At fill up my DTE said 737. I calculated 735 miles projected for this fillup based on my actual driving. It has to be the calculation that is strange, because the DTE was initially right on. I filled up with 42 gallons. Had less than a quarter tank left. I would estimate about 10 gallons per the gauge. That plus the 6 in reserve matched up to the 58 gallons.
I’m cheap and have never dropped below 1/2 a tank, normally fill up when it’s between 1/4 and 1/2
Guess I need to track miles and gallons along with dropping to 1/4 tank before filling up
Never got that paper, can you please post the information
