do you really save 20% on fuel ?

what if you drive mostly on highway
for example our gas tanks is 80L i get about 550km on a full tank doing about 118km/h on avg

i assume that wont get any better with pedal commander ? its mostly for street use ?

I've had a pedal.commander for about a month now. I like it because there is zero lag when I push the long skinny pedal down to move forward. My average fuel mileage hasn't changed but depending on how you set it up AND how you drive that could vary. IMO, it's worth the money based on how I drive.

I have a sprint booster which does the same thing. There is no way anyone is seeing a 20% boost in fuel economy from one of these things.

There's no fuel savings.

Pedal Commander and Sprint Booster are merely electronic amplifiers. There’s lots written about them on this forum.

Think of it like this. You push the pedal down 1/2 inch and the engine responds as if you pushed the pedal down 1/2 inch + x inches. Where x is determined by the “boost” value you set the device to.

No additional horse power, no additional MPG. Just a quicker response to your foot.

I probably lost 20%. (I drive like an a$$#ole.)

As stated above. No fuel savings but it removes the annoying pedal lag feeling the 4R has from the factory..I put a PC on mine two months after I bought it, installed and pretty much forgot about it.

You won’t save fuel but you will thank yourself for installing it

It's really more than just duplicating pushing the pedal down further. It provides a quicker throttle and transmission response than what you can achieve by simply "mashing the pedal." If my sprint booster is set to "Race 5" on the highway it provides me with an almost instant throttle response and kick down allowing me to quickly make a passing maneuver. If I turn it off and try to duplicate it by "mashing the pedal," there is still an unwanted delay. These devices are simply an aftermarket solution to what most cars include today as standard equipment. The majority of cars, today, come equipped with different drive modes....be it economy, comfort, sport or sport plus. These modes change throttle input and transmission shift points. I equate my 4runner's factory throttle to my wife's BMW in eco mode.

@ElectroBoy is correct. It amplifies the signal from the pedal thats it nothing else.

Pedal Commander and Sprint Booster are not analogous to driving modes in a BMW. Those modes change a lot more than throttle input, they change suspension, steering and transmission characteristics. PD and SB do nothing other than amplify throttle input. Any change to fuel consumption will be a function of how you drive.

No way would you save fuel.

so why do they advertise 20% lol


heres another question that.. i know you guys mentioned lag..
but i picked a 2021 venture and there is no lag.....

mind you i came from a bmw X6 M
.. is it possible for 2021 they made it so its more responsive ?
ive never driven any other 4runner

maybe someone here who has an older one and has a new one now can tell me if they feel the new ones are more responsive ?
because i really see no lag in mine

The Eco mode is like grandpa driving for around town. It really slows down throttle response so no one would use it in the real world.

The claim has the wording "up to" which makes the claim plausible. .00001% fuel savings is within the "up to 20%" range.

Because it is promotional advertising, and carefully worded.

"can" help you save "up to"...

Notice nowhere do they say anything about "how".

I'm not banging on PC or SB. I have a Spring Booster in my 4Runner and I love it. I would have been just as comfortable buying a Pedal Commander. I consider them interchangeable. Wouldn't go back to stock. I don't expect it to do anything for fuel economy. That's not why I installed it. Slowing things down even further to try and save fuel would be counter productive to why it is needed to begin with.
