How to make Power Mode the default driving mode.

I am confused as to the purpose of this mod. I understand the car will default to power mode on startup but will it go back to normal or economy after a while or will it stay in power mode? I think it would be very useful if it could be designed in such a way that it would be speed sensitive. In other words, shift to power mode when speed drops below let's say 15 mph and out of it to whatever mode it was originally in after 10 or 15 seconds, or when car reaches cruising speed, say 35 mph or above.

 

That's sort of moot as you should be gliding anyway at cruising speed, in which case it doesn't really matter what mode you're in.

 

Well, in any case a better/simpler fix would be via software hack- but no one has found that yet....

 

I agree but I have yet to glide at speeds higher than 40 mph and when there are inclines or declines, cannot glide at all. I have also found that in power mode the gas pedal is just too sensitive to comfortably maintain constant speed without using CC.

 

Yikes. Strong work and all but sheesh...pushing the POWER button is about as much work as putting it into DRIVe.

 

I ordered a pair of those 528T modules today

Thank you for sharing the design.

cproaudio, forgive me if this is the wrong way to send you a message. i'm new on here. just bought a 2012 prius four. would like very much to have power mode as default. i could get the three-button circuit board out, but never done any soldering. is there any source to buy some sort of plug-n-play module? or are you aware of anyone doing these modifications for hire via mail? could probably do some of the assembly myself with more novice-friendly instructions. thanks for any help.

Way better mpg's in power mode the eco mode, I'm from Missouri, show me

eco mode simply uses less gas, and power mode is entered by pressing harder on the gas, I fail to see how pressing on the gas saves gas

 

Additionally, by running with a larger average throttle opening, you are reducing pumping losses within the engine, which does have an effect on fuel economy. I forget which automotive magazine did the experiment a while ago, however, the crux was a partially closed throttle plate was a big enough issue to cause a statistically valid difference in MPG between accelerating gently to speed and accelerating aggressively to speed.

 

The difference between eco and power modes is the amount you press the pedal, err, if you drive in eco mode you can accelerate just as efficiently, effectively, if you press the go pedal, and then when you're at speed, you're also in eco mode, saving gas
In power mode does the traction battery try to help as much as when in eco mode?, I think not...
And you aren't bothered by pressing the power mode every time you start the car

 

Peeps, especially the new ones: PWR Mode does not make more Power.
It just changes the ratio/curve of the gas pedal movement.

You all can save yourselves a lot of time and effort by just moving the toes of your right foot another inch when you want more POWER.

Full Pedal = Full Power.. No matter what you do with those silly switches.

Are some of you really messing with this while your car is on warranty?

 

I do what I want with my vehicles. Prius is so reliable that I don't worry about it It was proven a while back that runnin in PWR mode all the time makes the car achieve higher mpg's than ECO mode. I have a pair of those timers and will install them someday when I get some spare time. Until then I push that button when I remember to.

Mike,

How is that explained???
The car accelerates as fast, or as slow, as you command it to with your right foot,,, no matter what silly button is pressed.

 

Hmmm, trying to remember what was said... Something about accelerating quicker to get the car into the higher mpg numbers sooner rather than accelerating slow and keeping the low mpg numbers for a longer time. I know it works well on my car using PWR mode verses ECO all the time. At first I called bullshit but then gave it a shot on a few trips across town and seen on my scanguage that it was up significantly. I ordered the 2 timers required and have the schematic at home to whip up the module and harness when I can get to it. I still haven't driven my car since last fall

Mike and guys,

You said: Something about accelerating quicker to get the car into the higher mpg numbers sooner rather than accelerating slow and keeping the low mpg numbers for a longer time.

That is a function of your right foot. Not what silly switch you press. The switches only change the response curve of the throttle pedal.

There may be something to getting up to cruise speed and not spending a lot of time getting there.
Similar to Jet aircraft getting to cruise altitude quickly.

But once again,,, That is commanded by your right foot. Those switches don't manage the power/fuel economy. Your FOOT does.

 

Makes sense. I know how the car functions and pretty much know what has been experimented with since the 3rd Gen came out. Try PWR mode and record some data if you like. It works

Everyone has their own way of achieving the same or similar results. To each their own
