Hi all,
So let me give out some info.

2018 f150 4x4 sport supercrew 2.7 twin turbo with roughly 24,000 miles 10 speed trans.

I deactivated the auto start stop through forscan, sometime ago, doing this allows me the luxury of getting in without having to push the button upon starting the engine.
however doing this has caused my mileage to drop, since then i have looked at ..... maybe.... just maybe.... reactivating the system and purchasing the eliminator and installing it.

The idea is that by using the eliminator vs forscan my mileage will once again rise. However before I invest in this. I'm asking for your reviews on the eliminator.

many systems work together to boost mpgs, yes ... i know that... i just want to know.. those that use the eliminator, do you still enjoy high mpgs vs the disabled start/stop through forscan and only getting roughly 15-16 mpgs.

 

I unplugged the connector buy the emerg brake and no change in mileage, I never tow so not an issue but that said no change in mpg.

 

No change in mileage, but most of my travel is highway.

 

Unplugged the connector next to my left foot and found out it's my right foot that affects my mpg's.

Seriously, 22-23 with s/s disabled.

 

I've got a 5.0 and my average mileage in the last 1K miles has been around 20 combined. I don't have the eliminator. I just push the button. Good mileage is all in how you drive.

 

ive only used the eliminator because it turns off (or on) JUST the auto stop/start feature and locks it at whatever you selected.

Disabling it in FORSCAN, pulling wires out of plugs, installing fake trailer plugs actually disables the Battery Management System which in turn, disables the Auto Stop/Start.

You shouldnt see a drop in mpg between one vs the other.

 

From what I'm getting ... the battery management system monitors charge levels of the battery, the auto start stop feature is hard on any battery with the constant on off. the b.m.s. reads a low battery, it sends a signal to the alternator to raise the output voltage upto 13.5 in order to charge the battery, this in turn creates a load on the engine, which then affects mpgs.
Once the battery is charged, the alternator is then regulated to an as needed voltage to power the vehicles active systems.

with the a.s.s. disabled the b.m.s. is also shut off, b/c of this, the system seems to go into a default mode of constantly providing 13.5 volts without regulation.

I figure this is what is happening so that's why I ask if the eliminator has any effect to mpgs.

I have seen the other ways. Unplugging connections under the dash, the trailer plug, sport mode... etc.

I do pull a trailer sometimes, rarely use sport mode.

 

I was getting 19 before I disabled the a..s.s. and after, I max out at about 16.2.🤔

 

Any chance you disabled the function right around when winter gas was introduced in your area...?

*** doesn't produce a noticeable MPG change like you describe. However, over an entire fleet of vehicles, it produces a sizeable reduction in the use of fossil fuels, that's why it exists.

 

*** is part of the battery management system as in....if the battery is too low, the truck will stop itself from shutting off so you dont have a dead battery at a stop light. Hitting the button to turn off ***, does not disable the battery management system, all the features of BMS will still work if you hit that button everytime you start your truck or if you use the eliminator.

All the eliminator does is keep the button on or off, thats it.

If you disable it a different way buy actually disabling the BMS, then i dont know how that could effect gas mileage...
