DTE Calculation

Im sure most of you are aware of this but in the setting screens there is a DTE Calcution for Normal and Towing if you are in Normal and you have 300 Miles to empty switch it to Towing and it will add roughly 50 to 60 miles to the DTE reading? I find that odd since towing should be less since it is worse on fuel mileage vs regular driving (no towing). Anybody else notice this and was curious to hear other thoughts about this. The difference in the reading for towing and normal is roughly the same as the Fuel Tank TSB fix that is out there right now ????? just an observation

Have you been using the towing DTE for awhile? Someone posted about this in the past and I thought he said the DTE will eventually even out back to the normal.

No I just figured it out but I'm gonna keep an eye on it. The strange part is I haven't towed anything with my pick up yet and it still reads 50/60miles higher for DTE in towing then in normal. ???? I have 13500 miles on my pickup

As I understand it (pretty sure I read it in the manual) the 'Tow' mode just changes the calculation so that it only averages over the last 60 miles driven, the regular mode uses a larger sample 500 miles maybe? can't remember.

That may have been me. I got tired of switching it back and forth. Left it in "tow" setting. After driving awhile without the trailer, it gets back to 700-800 range even though we've selected the towing for DTE. I, too, believe I read that it's the last 60 miles for towing and last 500 miles for normal. If that's what's happening and your last 60 miles avg is higher than the last 500 mile avg, you'll get a jump up - and we do after a day or two of driving without the trailer. Ours also seems to make the most drastic changes when you shutoff and restart the truck.

The confusion maybe that it's not choosing an avg when you're only towing or running solo. It's just the last miles the truck's been driving. Your choices, if we've read the manual correctly, are to avg over the last 500 miles or 60 miles.

HTH, David
