I've read several times that placing a larger fuel tank or adding a tank to the bed will trip the stock computer and throw a code. Something to do with stock computer not recognizing high miles to stock fuel tank capacity.
Anybody with larger fuel tank or bed tank have problems with any tuners?
Any tuner vendor/programmer with info on this?
thanks in advance
I plan on installing a Titan Super Series tank in my this coming spring. From what they tell me there is no error.
Most people that saw the error where those using the early Express UFS system with the transfer flow tank as the tank's level would slow or stop near the 1/2 mark when the pump kicked in and began transferring fluid to the OEM tank. This pause or reverse in level while the truck was motion kicked up the error that you had a faulty in tank sensor.
However from what I've been told by transfer flow this error has also been eliminated by changes in software not only in the transfer flow electronics but in the OEM ECM as well.
Now provided what I was told was false and you still receive the error. Having a DashDaq or any code reading tuner installed will allow you to read, decipher and clear the code in question.
I think both Titan and Transfer Flow offer great products. However if I was buying a direct replacement tank (which I am) it will be the Titan due to the rugged nature of the construction. If in the future I decide to augment my 67 gallons of fuel with an in Bed tank, it will be a Transfer flow.
Of course I may not have to do both as I plan on adding an F450/550 with a hauler body to the collection in the next few years. Which of course will have an added tank...
Of course as fuel prices steadily rise, I may not be driving anything
