Can I run with ECT Power mode continuosly?

Well it could, once again, simply be an apples to oranges comparison. Maybe things are different even between IS250 and IS350. I only compared a 2013 IS250 to my 2007 IS250. Throttle tip-in is noticeably different in the two modes in mine, that's for sure. Maybe the throttle still changes in IS350s? Like I said before, I'm not trying to definitively say that this is true for all 2IS's. Just offering my own small sample of anecdotal evidence.

Yes, the throttle tip-in is noticeably less aggressive. I've always preferred a long-travel, floor-hinged pedal, just like the ones that could be found in my parents' '91 and '96 LS400s, so the less aggressive throttle mapping in ECT NORM is a great thing to me. Sorry to get off topic, but I have to mention: You would think floor-hinged pedals would be getting floor mats trapped over them all the time, leading to unintended acceleration, but who has ever heard of a runaway LS400?

No change.
Just like your MY2013 loaner.
So my experience is definitely not the same as jgr7 MY2012 who said "My 12 IS350C speeds up when put into pwr mode.", right?
But I notice that his car was a 350.
Was jgr7 doing exactly the same test as us I wonder?
Also, as you said "Maybe things are different even between IS250 and IS350."

Another way to tell (This is true for ALL Toyotas since at least the mid-'80s): The sticker inside the driver's door jamb has the info underneath the barcode under "A/TM:", short for Axle/Transmission. In this case, mine reads B03A/A960E. My old Corolla said -02A/C52, as it had a C52 manual transaxle. C/TR also tells you the color code and interior trim code. I could go further into it. but that would be going way off topic here.

I didn't know that information was there.
Very interesting and useful to know.
Thanks.
I'll have a look next time I take the car out.

Great.
Thanks for that explanation.
I think I've got it now.
" .... but who has ever heard of a runaway LS400?"
Just checking you're joking here?
The LS400 _did_ run away, right?

Yes, p156 of the MY2011 IS250 F-Sport Owner's Manual is quite clear.
"To improve fuel consumption and reduce noises (sic), set the shift lever in the D position for normal driving."
Unfortunately, they do not say what position the ECT Pattern Select switch should be in.
Presumably, Normal mode position.
As you may have noted earlier in the thread.
Others report no difference at all between ECT Normal and ECT PWR.

Mine (MY2011 IS250 F-Sport) reads the same i.e. xxxx/A960E
I did not make a note of the xxxx part of the code.
I don't think it was B03A though.
No matter.
Thanks.

On another note, if anyone wants to see tangible proof of changing throttle mapping with the ECT PWR/NORM switch, try switching it on a flat, level road at constant speed and constant throttle position with the display in the gauge cluster set to the instant fuel consumption graph. In this test, I can see a considerable change in fuel consumption each time I switch modes. This is a more quantifiable measure than seeing any perceived change in vehicle speed.

Yes, of course I'm right! (Kidding). From being interested in cars and growing up in a family where just about everyone drives a Toyota product, as well as 10 years of owning an AE102 Corolla, I've amassed an almost disturbing level of knowledge about Toyota and their products and procedures. I'm always glad to be able to share this knowledge. If I don't, it means knowing it is all for nought.

That's a nice thought and outlook on life.
<.... try switching it on a flat, level road at constant speed and constant throttle position with the display in the gauge cluster set to the instant fuel consumption graph.>
I'll certainly try this at the next available opportunity.
In the meantime, I'm still struggling (and enjoying) to understand exactly what the ECT is doing in my car.
Stand-by for more questions!

Pwr mode turns off and on by itself.
