The PWR ECT changes the electronic shift points of the vehicle auto transmission/gearbox provide more power/torque and less economy. How it does is to hold each gear to a higher RPM.

For example when you drive normally with PWR ECT turn off the vehicle auto transmission/gearbox would change/shift the gears from 1st to 2nd and 2nd to 3rd at 3000 RPM. When you drive with PWR ECT turn on it will change/shift the gears at 4500RPM.
