I have tried activating this switch and I cannot detect any differences in performance or shifting. What should I expect?

You should actually notice higher revs, smooth and quicker acceleration. If you dont notice the difference......take it in to Lexus for a check up.

Happy IS Cruising.....

What do you mean by higher revs? It shifts at 6500 regardless of the switch position. How does yours behave?

hmm.. obviously if you jam on full throttle, you won't notice a difference since it shifts at redline.. but in regular driving, ECT PWR lets the car shift gears at higher rpms.

The ECT PWR button does not necessarily make your car accelerate faster (i.e., there's no increase in power or acceleration), but it does change the logic of the automatic transmission to make it more "sensitive" the throttle position.

You can try this: In ECT "Regular mode", cruise along at some speed and then push the gas pedal down some distance (not fully). The car may or may not downshift to accelerate. Next, activate the ECT "Power" mode and cruise along as before and depress the gas the same distance as before. The trans will probably downshift immediately to bring your speed up quicker. This has nothing to do with the engine output, only gear selection.

ECT PWR will make your car feel more "lively", whereas "Normal mode" may be more comfortable to drive since the car will not change gears as readily.

It shifts at about more like 6200RPM. Not one of the higher-revving engines out there, but smooth and turbinelike. 6500 would be nice if the torque climbed into that area, and your top end would be closer or over 150 if you could pull redline in 5th gear. Also, and overdrive for less revs at highway speeds would give you over 30MPG. Lexus, are you listening?

Emerald,
I agree with you regarding a higher fifth gear to reduce RPM's. I would gladly give up a few top speed MPH for more highway MPG.
