Indeed it is your friend 
And its true, without ECT, kicking down to second gear at around 45-60 mph takes years on end. ECT allows for a much quicker downshift. Usually around 60, i just turn O/D off to drop into 3rd if i need to be picking up speed, rather than having to push the gas down halfway to shift (with ECT off its like halfway down the pedal before any shift.).

If you're an aggressive drive keep it switched on, if not leave it off and the computer will decide when to turn it on 4 u. every auto trans computer switches automaticly when nec. it's written in the programming.

ECT - Power
I've been driving around with the switch in both modes and noticed its not how much gas you give, its more so How quickly you do it. In both modes, even a small amount of gas if pressed quickly causes a downshift. It seems the ECU senses your urgency and acts accordingly. Try it on the road next time, in power mode press a small amount throttle quick and you get a nice 1 gear downshift. If you push it slow, you’ll find yourself pressing until your at near full throttle when you get an overkill 2 of 3 gear - 5K RPM downshift which many times not what I was trying to do. You guys probably already knew this, Sorry I’m new to the automatic scene and am still trying to figure it out

It definitely is quicker to downshift in ECT; otherwise, ya gotta hit "the button" to get it to downshift, plus it shifts first to second waaayy too soon most of the time. I'm thinkin "what the hell, why won't it go?"

I used to use the ECT as a poor man's traction control for rainy day driving, but after the last couple mods, that is now out the window.
The downshifts come pretty quick with my ect turned on, and sometimes I'll turn the regular mode on while cruising in traffic when I'd rather not downshift, and always around town when I remember to do so.
While tuning the mixture I found that the vacum signal that triggers the shifting is easily changed, causing either a super quick downshift, or a lazy downshift, luckily it turned out where I like it when it was all sorted out.

High revs, fuel pressure, low revs, screw on the side of the MAF, under an aluminum plug(factory seal).
PM me if you want more details, tips, precautions, glad to fill you in, but I don't want to sidetrack this thread/poll.

I dont know if this makes any sense but today I got on it just once with overdrive off and ECT on and then turned ECT off and OD back on and the car shifts a million times better now.

I left it on for a full tank of gas and averaged 15-16 MPG, and with the ECT off, mostly I got 19-20MPG, not exact science but I don't think I change my driving habbits much when it is on, but I think it is more fun to drive with it on...but I almost never drive with it on lol, I don't know why either.

When I was in Texas, I would switch it on when I was playing around or really wanted to pass someone fast. The traffic here in CA is a nightmare, so I found that lately I just leave it on.
You never know when that 745Li might want to show of....
BTW- The direct injection makes those models accelerate pretty fast.
Agressive; leave it on.
Normal; leave it off.
Girlfriend/Wife; turn on ECT Snow

I live in the suburbs of chicago, i always leave ECT on. I found that i get better gas mileage when it is on. I'm speculating that this is because in the crazy traffic here, with ect power off i end up smashing the pedal to the floor to downshift, where with power on i can just press it down half or 3/4 of the way.
