ECT PWR button

On my 2020 sr5 whether using the S modes or D there really isn't any performance difference other than being in that S mode gear chosen. I can get about the same results in the D mode when the transmission senses it needs to downshift, and it does at the precise time according to roads grade. ECT is another story....longer shift points, and a louder/different engine tone. Fuel economy is like having 2 more cylinders....it sucks. Imo, ECT is only for trailers that are over 3k lbs.

 

Apparently the newer models are tuned a little better and don’t feel as gutless.

 

Averaged about 19 mpg using the ECT button driving from Albuquerque to Denver and back while running a 2” lift and slightly larger tires. Definitely helps a bit when driving uphill, the gear changes isn’t as weird.
