Just a quick question. My 01' International has a green button on the dash that says "fuel econ". I know that the IC's in later years also have this switch.
My route is mostly in the country and a bit on the highway. I then come into town and drive the city streets. It's the reverse in the afternoon.
What benefit would i have by switching this switch on? Another driver told me "Don't bother with it. Just drive it!"
I notice that the bus handles a bit better in the country on slippery roads with the button on.
All it does is alter the shift points on the Allison transmission. You may get better heat to the heaters with button off and slightly better fuel economy with it on.
I believe it is the same as the MODE button on later transmissions. When engaged, the transmission will go to higher gears quicker so the engine doesn't rev up as high. It also holds a higher gear longer before downhifting. Lower engine speed equals less fuel burned but it also may mean lower power. If you're in the country, I'd turn it on and monitor the fuel mileage for improvement. Every time you shut the key off you may have to turn the Econ switch back on.
T444E "Fuel Econ" button...benefits?
