Eco-Boost Economy Mode

[TarnishedCopper]

I just picked up my 2023 STX about 12 days ago. After about 1,200 miles and two fill ups, I’m netting just about 23mpg with the little 2.7L. I was surprised bucking a stiff headwind in Iowa last weekend, I still pulled 19.5. My past 3.5L’s wouldn’t come close. I tried the eco-mode for a spell, and it did absolutely nothing. Fine with me. No additional motion every time I start up. Just got rid of that start-stop crap for that reason.

My truck came with the start stop garbage removed. I wonder if that also shuts down the ECO mode? I can tell driving if in the regular mode and switching to the ECO mode that you lose take-off power, and gain it back when switching back to normal mode.

I do have an ODBII scan tool. I didn't know that would tell me about the boost.

Your IPC center 2 gauges can be configured to show different things. One is boost. Use the menu key on the steering wheel to select it.

I find in ECO mode, the gas petal has to be pressed farther down to get the same speed as normal mode. If you only push the petal down ( 1 inch say) the same as you do in Normal, should be saving gas. Will be slower acceleration and may change the shifting of the transmission. I don't use it.

Yeah. You keep telling yourself that buddy. Now, put down all sharp objects. Slooooooowly walk away from that ledge. Easy now. Help is on the way.

I’m calling bullshit. You musta had a gale force tailwind.

Agreed! Strong tailwind, flat or mostly downhill, maybe mirrors folded? haha. Either way this is not a realistic daily expectation.

 

[Kanuck]

The truck was in neutral and people were pushing downhill.

yes i dont get this every time but dam it was shocking so had to take picture of it for proof lol

I don’t get better mpg with ECO, and I notice that when you try and slowly gas up from a complete stop all the way up to your desired speed it gets worse mpg as well. For me, hit it hard from a dead stop getting to speed and then coasting on electric seems to be the best mpg.

I think eco mode just shifts the fuel, timing, and transmission maps to use less fuel, with the expected less power.

You should get surprisingly good mpg driving between 20 and 65 mph, even slow moving traffic as long as you're moving. Even on a stock truck, mpg suffers terribly under a few scenarios (from my experience):
* getting up to speed from a dead stop, i.e. light, stop sign, etc.,
* going over 70 mph. Mine will drop a little going 70, and then drop quite a lot going 80.
* wind, surprising has a large impact if you are 65mph+. Factor in a headwind and you'll see a significant drop.
* cold starts - the engine runs pretty rich on cold starts and will suck quite a lot of gas for the first few minutes

I think some of the best mileage you will see people posting are those that drive back roads at 45-50 mph to get to/from work with very few stops.

My 2021 supercab F150 3.6l PB does better in eco when driving in an urban environment. At interstate speeds, 2 mpg worse than regular mode.

I am wondering why we only saw that mileage one time.

Wind. I set mine to Eco every time I get in, and as far as I can tell, it does nothing other than reduce the digital throttle response.
The engineers spent a lot of effort on the aerodynamics, the louvered grill and the air dam curtain that comes down. Seems between 40 and 50 mph I get the best MPG's.
On long highway trips I'll get behind a semi in 'one car length' mode for the radar cruise control and it will get 22-25 MPG at 75 MPH that way. The truck drivers don't seem to like that at night though, I think it's the headlights. My overall average is right at 17 MPG.

Thìs has been my experience too.
- at stoplights i try to baby it up to speed. I wonder if it would do better by trouncing it to let the truck take better advantage of the electric motor in hybrid mode when first starting up? This may be an example of where decades of training ourselves to save fuel needs to be unlearned in the age of hybrids.
- cold starts. A lot of my local day-to-day driving doesnt go far enough to warm up the ICE. Consequently, my mileage when being driven like that is in the low 17s. Over the past month or two I've had cause to do mostly the same type of driving but for longer distances and I'm getting in the low 20s.
- Backroads - recently we took the truck to the beach here in the Pacific NW. 75 miles each way, twisty-ish roads crossing the coast range with speed limits varying from 55 to 65. We got in the high 22 mpgs. I think your observation is correct.

I'm guessing downhill, foot off the pedal and had just reset the MPG. LMAO
