Very true. Still the most sophisticated solution yet to this annoying problem!!

After reading all the different posts about eco and slippery modes I have been trying both of them on regular routes for weeks. The slippery mileage in the mountains is better than eco and eco mileage on flat interstates seems better than slippery.
Last week I tried normal mode again after driving in normal (because I didn’t realize eco reverted to normal when shut off) for almost 9 months. Honestly I don’t think there is much of a difference in mileage driving in normal vs slippery. My mpg driving a 29 mile trip through rolling hills at 50-55 mph gives me between 57-63 mpg so I’m not fussy about the mode anymore. I’m thrilled with the mpg
Basically, every 'mode' just changes the charging, and power output. Essentially, you can do it all with your foot pedals.
At normal, you have a moderate amount of power output to move forward. And when you let off the throttle, your 'charge' defaults to about a quarter or so of the green charge on the chargemeter.
In ECO, your power output is reduced slightly, and your charge defaults to about 2/3 or so of the green charge when you release the throttle.
Now, the other direction:
In Slippery, your power output remains similar to normal, but your 'charge' is reduced by a lot to avoid tires suddenly slowing on slippery surfaces. When you're doing a lot of driving and a little coasting, you're not 'losing the excess charge' you do in other modes where you're constantly maxing out the battery while driving. It does give you a much smoother ride.
In Sport, your power output goes up a lot, but your charge level drops, similar to slippery. This gives you a much more responsive pedal for power. Less touch needed, and quicker reacting to a press. You sacrifice MPG because it defaults to hybrid much quicker.
In Tow/Haul, your power output peaks, and your engine runs every time the vehicle moves, to help avoid any straining moving a heavier truck. Charge goes up a lot, as it's using the engine to charge the battery and run the battery for power throughout the drive phase. This gives you a pretty strong 'engine' brake effect. Both when the battery is charging and when it maxes out and uses the actual engine to help stop. Also gives you your brakes immediately rather than when you max the green charge bar.
In LOW, you're single pedal driving for most conditions. Max power assuming you need it, but also max charging by default (100% of the green bar immediately). This allows you to feather the throttle to speed up and slow down.
What's nice about LOW is that if you're in hilly, slow terrain (think creeping through a national park), you can use one pedal for most of the driving unless you're fully coming to a stop.
All in all, though. All this power? You have access to it in Normal with your foot. Your charging? You have access with it from the brake pedal before you max it out and start using the service brake.
The settings in a hybrid for drive modes are just to assist you with your driving style and regular routing.
I've used slippery and in some conditions its great. Though I found hillier terrain works best in normal, where eco is best for flat ground with more 'higher speed' streets (45mph or more). Slippery seems to be best in 25-40mph streets that are mostly flat with stop lights spread out where you're getting consistent charge over longer stretches of driving before coast-charging and then using the electric to get moving again from the light/stop sign.

I installed the module today and it works great. (My mav module that is). Getting it installed with the Vais sirius xm module behind the Mav fuse panel sure loads up the free space. My question is why does Ford not want to retain the drive mode setting on startup ?
Potentially apocryphal but supposedly when EPA testing if the vehicle can be permanently set in a configuration that delivers worse fuel economy that is also averaged. (Likewise better fuel economy, but usually it's easier to deliver bad MPG than gain it)

It's weird because I rented an F150 before getting my Mav (It's what caused my want for a Mav to go into overdrive) and in that truck if you had Eco mode set the last drive the next time you turned it on a prompt on the dash screen would ask if you would like to go back to that mode, I assume it worked for any mode. I was sad to find the Mav Didnt have the same thing but this module is even better because I don't always look at the dash on start up.
I don't know if it would cause a problem, but my plan would be if I need to get the car emissions tested in the future, to press the far left button on the MyMavMode module to turn it off before hand.
The obligatory "Voiding the warranty post" for all mod threads
"before they can deny warranty coverage, the manufacturer or dealer must first prove the aftermarket or recycled part caused the needed repairs."
https://consumer.ftc.gov/articles/auto-warranties-service-contracts
The Magnuson Moss Warranty Act requires manufacturers to honor the original warranty unless they can prove that the aftermarket modification (either the parts or installation) was responsible for the failure that caused warranty repairs.

aybe the same guy that sold these black boxes to improve EV efficiency in Washington DC. But apparently this one works. Still would not do it though.

My Honda CRZ also defaulted to normal mode. However it had a button for each mode. The Mav I have to click the button four times.
Save your fingers and let a timer do the clicking LOL. Build your own or just buy one of these.
Has anyone built and installed the Cuban Redneck's version?

Correcting your username for you. Should be "MAY VOID YOUR WARRANTY" is getting OLD, MAN

Physical relays would drive me nuts. That's a lot of clicking.
