I spent some more time studying the FORScan change required if swapping OEM 26 gallon tank for Titan 48 gallon tank...
As Built Value: 6003 D900 0067 (3D9 = 26 gallon tank)
Modified Value: xxx7 19xx xxxx (719 = 48 gallon tank)
Below is how the math works out on this...
Comments in FORScan spreadsheet:
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.
kdjasper calculation validations:
26 gal = 98.4207 liters = 984 decimal = 3D8 hex ... (985 decimal = 3D9 As Built Value)
30 gal = 113.562 liters = 1136 decimal = 470 hex (FORScan comment in error)
34 gal = 128.704 liters = 1287 decimal = 507 hex
40 gal = 151.416 liters = 1514 decimal = 5EA hex
48 gal = 181.7 liters = 1817 decimal = 719 hex ... this should be precise as no rounding was needed going from liters to decimal
50 gal = 189.271 liters = 1893 decimal = 765 hex
55 gal = 208.198 liters = 2082 decimal = 822 hex
So, it looks like Distance to Empty (DTE) could even be more accurate with the 48 gallon Titan tank over the 26 gallon OEM tank because of the 3D8/3D9 caused by rounding for the 26 gallon tank calculation.
Now that my head is into this, I am confident swapping out for the bigger tank when it becomes available.
