I realize that Eco-Pro is quite controversial here. People are so unhappy with it that they are changing the coding to remove it.
I'll be the contrarian- I have no problem with Eco- Pro. Of course it saves gas mileage- the engine is off when the car is idle for more than 5 seconds. I like spending less money on gas, now and in the future.
