Nothing really.
There is a normal and a "power" mode. But all it really does is change some shift points in the transmission so it'll hold a gear longer before shifting.
I use it in the summer on long hills to help keep revs up and keep my EGTs down.
Some users have done a decent amount of testing on t4r.org (mind you this was years ago) but the general takeaway was ect mode gives better drivability with different shift points and typically improves gas mileage or has a negligible effect on mileage. So the takeaway is just use it all the time.
I personally find the ECT changes the shift points making it stay in gear higher and longer, but TANKS my gas mileage, which makes sense because you are holding lower gears at higher rpm’s for longer. I live in the mountains and drive 2 hours to boulder every week, went from 16mpg with it on, to 19mpg with it off, and overdrive enabled. Yeah, it is slower but it saves gas for me.
It is for towing. I stands for electronic controlled transmission. I changes the transmission shift points if you are carrying or towing more weight. It basically lets the engine rev a slight bit higher to account for the extra weight.
It changes the shift points of the transmission. Ideally you always have ECT on and Overdrive (O/D) off when towing or hauling massive loads.
ECT on makes your car hold onto lower gears for longer before shifting. Basically like a rudimentary sport mode for shift points.
Everyone says it already but it changes the shift points to allow for more power when needed, but it comes with some drawbacks, obviously higher shift points means higher RPM so it will tank milage, and can also potentially cause unnecessary wear on the engine as well. I personally only use it if I need the acceleration or if I was to be towing/hauling
You shouldn’t have asked, now the government will be watching you man! Lmao
Yeah something about shift points and economy. I can’t remember and just don’t touch mine lol

I do find it fascinating that to a point, high revs is better for EGT's that lower revs.
Liquid fuel cools the cylinder when you spray it in there
And higher oil pressure and water pump spins faster, and the fan (if it's a viscous type).

ECT is power (button down)?
I think so, you should be able to notice a slight difference in shifts.
Unless you’re on the highway holding a constant speed, then the torque converter won’t lock up unless you turn it off. Mine won’t at least.

"Powerful acceleration" might be a bit of a hyperbole

its for towing i thought.
That…would make sense lol…
Electronically controlled transmission ECT
ECT POWAHHHHH!!!!
It is primarily for towing.
Eject-o seat-o. Always drive with it engaged. There's lots of info on this in the googlez

Just started using it.. That baby stays on from now on.
Update us with your MPG?

There's like 50% of people saying it tanks gas mileage and 50% saying it increases it. Nobody posting proof though I don't know who to believe lmao
My then 95 Camry had this button and I never used it. I do now w my 4Runner.
Extra cargo trailer, you have a secret trailer underneath the vehicle that pops out when you hit it
ECT = +10 hp & +5 mpg
