Default PWR mode

I am starting this thread for supporting the up coming PWR mode mod in PriusChat Shop.

Let me start by saying that this thread is not a debate for driving in PWR mode. There are many threads about that.

Features​

• Activates PWR mode upon powering up your Prius when switched ON.
• Normal operation when switched OFF.
• Turning on the PWR mode mod while the car is in READY will engage PWR mode approximately 2-3 seconds after it is switched ON.
  
• Adjustable delay 0-5 seconds to work with any Prius with PWR mode. It could probably work with other Toyota Hybrids with PWR mode too.
  
• Optional trigger input. If you're too lazy to reach to center console to activate the PWR mode, you can add your own push button switch and mount it anywhere you want to activate and/or deactivate the PWR mode. You can mount it on the steering column, by the power mirror switch, in the door arm rest or on the steering wheel. Prototype version does not have this feature.
  
• Optional trigger switch is operational regardless if PWR mode mod is turned on or off.

FYI​

What is PWR mode?
It is one of four driving mode the Prius and Prius V offer. It reprograms the throttle for quicker response. When you're in ECO mode, powering off the vehicle will not reset this mode. When you're in normal mode, powering off the vehicle will not reset this mode. When you're in PWR mode however, powering off the vehicel WILL reset back to normal mode.

Why is this mod on the market?
Currently there's no known method for the Prius to stay in PWR mode after powering off, not even with ScanGaugeII or TechStream. There are a select few Prius owners who love driving in power mode because they want a Prius that can keep up with traffic and respond quickly to the throttle. This mod is catered to those who love to drive in PWR mode.

How does this mod work?
PWR mode can be activated after the Prius ECUs have powered up, usually about 1.5 to 2.5 seconds after you push the POWER button on the dash. This mod mimics the delay necessary to activate the PWR mode. Without this delay, the vehicle will not switch into PWR mode. The delay is adjustable between 0 and 5 seconds. Once it is adjusted to the correct delay, it will work every time. If it doesn't, readjust to a longer delay until it triggers the PWR mode every time.

FAQ​

What are the effects of driving in PWR mode? Brisk acceleration, keep up with traffic so you don't piss people off, Many people have reported increase mileage due to faster & quicker pulse and longer glide time.

Is this mod safe to use? yes, I have used this mod off and on for over 3 years.

Will this mod activate the Christmas tree lights on the dash? No. As long as it is installed properly and all the essential plugs are plugged in such as the park button plug, drive mode button plug.

How long is the pulse? Approximately .5 seconds. None adjustable

Can this mod be modified to lengthen the pulse? Yes if you're willing to open it up and replace the resistor. Warranty void if done.

How do I install this? As of this writing, there's no installation instructions. The basic steps for the Prius HB are

1. Remove necessary center console panels.
   
2. T-Tap the PWR wire.
   
3. Route the power, ground and trigger wires to lower cigarette lighter panel and hook up power and ground.
   
4. Route switch harness to blank filler and mount the switch.

It should take less than 1 hour to do. No wire cutting necessary, only T-Taps.

 

2010-2014 Prius Wiring Info



Wiring Diagram Based On 2010 Prius. I have no information for Prius v at this time.

 

Retail for $100. Hopefully by the end of 3rd quarter 2014. I'm still looking for people to submit installation instructions. If you're interested, contact me.
On my 2010, EV mode will not override the PWR mode. When the car is warmed up, it can be in both modes up to 25mph. After that, EV mode is automatically disengaged but still stays in PWR mode.

 

No, unfortunately I don't have a 2012+ to research on. It works on 2010 and 2011 but failed on the 2012+. I don't have access to 2012-2015 to find out why it's not working. This will only work on gen 3 but not Gen 4. I believe gen 4 cycles through eco, nomal and power mode.
