Pwr Vs. Snow Setting On The 2008 Is250

[fpuighs]

Does anyone know what the real difference is between the PWR position and the middle position (the SNOW position is the bottom position) on the switch for ECT.

Is it really worth switching from the middle to the PWR position if I want to get on it and make the car perform better? I live in southern california so snow isn't a factor.

Thanks,

You'll get snappier shifts with the ECT Pwr on. Also it will downshift sooner.

I LOVE the ECT Power function. Keeps the transmission in the lower gears longer for better performance. Need that to get as much power out of my 250 as possible. Hope to get a 350 one day, that thing must fly

The absolute fastest acceleration is obtained by leaving the transmission in d, set the ECT to normal, and floor the accelerator as hard and fast as possible.

I was playing around with the POWER mode. It does feel like it downshifts more frequently and when it shifts it does feel faster/sharper.

Anybody know if it does anything else like advance the timing?

It's just the transmission. ECT = Electronic Controlled Transmission

Does the gas consumption increase when the ECT is on compared to the Normal mode?

[mr_raider]

YEs and no. If you go light on the gas, it will not be noticeable, and PWR may actually get better in some cases, as the normal mode tends to "lug" the engine in high gear on inclines.

On the other hand, if you drive more aggressively you loose one or 2 mpg.

Oh..that's what that means :)

So far, for me, it seems pretty close (maybe 1mpg difference). I am able to be a little heavier on throttle in the city and get snappier results than with normal.

Haven't tried it on the freeway yet.

On the freeway, it's a wash. You're on 5th most of the time anyway.

Mine's in 6th most of the time above 30 MPH with slight gas or on cruise.

I think I have a magnet stuck on the bottom of my gas pedal. Whenever I put my foot on it, it falls right to the floor and stays there.

Ahh yess.... forgot about that 6th gear :D
