1 minute idle in Park = 7 cents of gas used... Throttle 7 to 8 % load 19 to 20.
1 minute of idle in "D" = 9 cents of fuel used... Throttle 8 to 9 % load 27... So, it was using more fuel in "D" than "N" and everything was warmed up to operating temps, is it BS what the manual says about the transmission going into "N" when stopped and still in "D" with the brakes on to get better fuel economy in traffic, then when the brakes come off it's back in "D"...???
The negligible cents per minute based on the ScanGuage is meaningless to me, but I would like if you can show us where the manual says anything about the tranny going into "N" while stopped, vehicle running and in "D"? I have not seen that claim in my manual. Maybe a new for 2020+ feature, or gas engine feature?

Automatic Transmission Adaptive
Learning
This feature's design is to increase
durability and provide consistent shift feel
over the life of your vehicle. A new vehicle
or transmission may have firm shifts, soft
shifts or both. This operation is normal and
does not affect function or durability of the
transmission. Over time, the adaptive
learning process fully updates transmission
operation. Additionally, whenever you
disconnect the battery or install a new
battery, the system must relearn the
strategy.
Neutral Idle with F350, F450, F550
Neutral Idle with F350, F450, F550
and F600 Chassis Cab Vehicles
Your transmission could reduce the load
on the engine when the vehicle stops, and
the gear selector is in drive (D) to reduce
fuel consumption and emissions. The
transmission resumes operation when you
release the brake. This feature activates
when the transmission is sufficiently
warmed, and the vehicle is on a level slope.

Adaptive learning is unrelated to a neutral idle feature. (Wrote before you added additional text) Is yours a chassis cab?
I wonder if that can be enabled in Forscan or something for the pickups as well. My F350 really wants to go all the time. In any other vehicle just foot weight on the brake pedal is enough, but in my 2021 I have to actively hold it there or the idle torque will overcome the brakes.

Yea, i do wonder why... This isn't done to ALL vehicles... I know, 2 cents a minute is right there with WTF, you care about 2 cents a minute it cost you sitting at a stop light to drive this truck...!!! You bought the wrong truck... Stupid you...
BUT, guess what, there are a lot of other things that can be done that aren't being done too, ... Anyways let's get back to that 2 cents a minute. On a normal going to work every day it was 10 lights going there and 10 lights coming home I sat there, let's just say 15 minutes every day X 2 cents a minute = 30 cents, X 5 days a week = $1.50. a week X 50 weeks a year = $75.00, that's 3 cases of beer a year, so it is NOT nothing... and... that seems easily accomplished with todays ECU set ups. JMO So... Why not.? as a standard set up for every vehicle...???
Careful guys. You keep discussing this stuff and the Company might institute the engine shut off on our super duties like they have on the lesser stuff.

But that would actually be worth it to have, $337.50. less gas to buy, for every year of use, for my scenario... Instead of just the $75.00 for the Neutral/idle in D feature, or the $0.00 that I have right now...
