I have a 2017 F350 Crew Cab 4X4 diesel short bed. I am wanting to replace the OEM tank with a Titan tank (I notice it's a 55 Gallon tank). My question, Is there a way to calibrate to a 55 gallon tank? I only see with Forscan I can calibrate to a 50 gallon tank. Is there another for a 55 gallon that I am missing?

I don't think there is a way to "calibrate" for an off-standard size tank. The fuel level indication will always be reasonably accurate; full will be full, half will be half, etc. What will be off the mark will be the DTE because there's not a means to adjust the ratio of former to current volume change, as best I can tell. Just don't seem to be able to locate a means to "calibrate" (adjust) for the volume shift for a non-standard tank size. However, I've been wrong before ... so someone chime in if they have been able to do it.

 

I guess I will calibrate/adjust it to a 50 gallon tank. That would put it close, 5 gallons off.

 

I found it................

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}-->Change asterisks to one of the following: 4 4A=30 Gal, 5 07=34 Gal, 5 EA=40 Gal, 7 19=48 Gal, 7 65=50 Gal, 8 22=55 Gal (This parameter is programmed to accept 4 digit Liters in this format XXX.x 55gal converts to liters of 208.198L so 208.2L rounded then drop the decimal 2082 decimal to HEX equal 822.)

 

Using that calculation I set mine to 52 gallon to have an extra 3 gallon for reserve

 

Nice find! I am glad to admit I'm wrong!
Which module did you change and what line of code?

Thanks for the info. It’s falling 28 miles short but it’s close enough!!

 

Back in 2011 I installed a Titan 50 gallon on my F250 shortbed truck. I took it to dealership and had them change settings to a 50 gallon tank . They told me it couldn’t be done and I told them the steps once they connected it to their computer. Seems Ford had several tank sizes to choose from. He found the 50 gallon option and it worked perfectly. I also had him turn on the daytime running light option which he said he couldn’t do . He said it’s an option I didn’t have . I told him it’s an setting in the computer, he found it and turned it on . Most trucks have all these settings to satisfy build options or state requirements. He learned something that day .

 

Looking for help from those that have been more successful than I. I have a 2022 6.7 short bed and have had a 55 gallon Titan tank for about a year. With ForScan I have changed theIPC line 720-03-01 with the 8 22 per the spreadsheet but have had no change to the DTE on the dash gage. As seen in the image, am I also required to change the 720-09-01 (see highlighted cell) to make the change work? I'm a bit confused. Many thanks in advance!

 

Yes, you need to change 720-09-01 too.
