my head hurts...they could have made this so easy...I wonder if AutoEnginuity will find a solution.

 

Okay, that makes more sense. I'll wait for your results until I run to the dealer for my change.

 

Actually I guess I forgot to ask the question is their wiring some where already on the truck for a second sending unit? Or if you add a unit (as in actually adding a second tank) do you hook it up either parallel or in series to the existing sending unit? Seems like that would effect how the computer interrupts the signals its getting. If their is 2 sets of wires then I don't see how it would be possible to tell the computer 2 tanks with 1 sending unit since the computer would "know" that's not an acceptable parameter.

 

Maybe you could tap into your sending units wires to send another signal to the truck (second sending unit/tank). It would see 2 tanks and figure the on board fuel as twice as much for the same tank level. Set the computer at 2-26 gal tanks and the on board fuel would drop at the right pace.
But when you have 2 tanks you would have a way to select between the 2 and the gauge would read whichever one you have selected. So your gauge would still be off, but your MTE would be very close.

 

UPDATE

Just as I suspected, despite programming two fuel tank capacities of 26 and 26 gallons, it only calculates the remaining DTE based on one tank with the parameters of 26, 26, one tank, one sender.

So no joy for anyone with a fuel tank over 40 gallons. Hopefully engineering will add some larger parameters in the near future.

 

I exchanged e-mails this morning with the IDS programmer for this feature advising that our customers needed to be able to configure up to 100 gallons in 1 gallon increments and that what was released on IDS doesn't provide much for the end user. Basically explained again the situation with aftermarket fuel tanks and MTE calculation and the range issue with the smaller tank size....so in short, I'm still working on it.

Thanks Paul. We'll hang out.

 

Thanks Paul.

 

Thanks I hope we can add 50 gals. Thanks again Paul.

 

I hope this can be changed. I miss my MTE!!!!!!!!!!!!

 

I beleive the Titan tanks are 52 gals? on a different note is anyone having problems with the sendig unit not reading a correct fuel level? I suspect that the plug for the sending unit might be losing contact - I might have loosened the connection trying to get it off of the original tank - Man what a pain that was - I couldnt see, and the harness is very short - I guess it was designed to be removed when the bed is off.

 

Quick update, I'm making some progress on adding configurable tank sizing to IDS other than the current standard sizes. The software will not support allowing input of a selectable variable between X and 100 gallons as I would have liked. However, after discussing with the software engineer, we're going to see if we can add a couple of the standard tank sizes that are currently available from the aftermarket.

From what I've been able to determine, Titan has a 50 gallon tank, and will have a 65 gallon tank shortly for the long wheel base trucks. Transfer Flow also has a 50 gallon tank. So at this point, I'm leaning towards adding just those two variables. If your aware of another tank size that should be considered, please provide your input in this thread.

Now all I have to do is convince the controls folks to allow these added configurations. Hopefully this won't be a problem and I'll keep you posted on the progress.

Peter, Thanks for your work to satisfy the larger aftermarket tanks, I know everyone will welcome this highly thought about IDC option. I just spoke to Titan and I will have some additional information to post as it relates to all aftermarket tanks (capacity sizes) I will also include direct contact information. Once again thanks.

Paul - sorry I got your name confused - I meant Paul not Peter. I apologize for that name snafu.

 

While the Titan is 52 gallons, I would be happy with a 50 gallon number. Close enough for me...

Thank you, Paul
