    ECON button - does it work?

    Having just driven a rental 2012 van with the ECON button, I have been wondering about it's purpose and whether it actually adds anything.

    My understanding is that the programming of the shift points in the transmission computer is altered depending on whether ECON is on or not ????

    When ECON is on (i.e. light ON), the transmission shifts at low speed are rougher, but presumably (from the name), fuel economy is better? Correct?

    When ECON is off, presumably the opposite is true - better shifting at low speeds but worse economy?

    So, for you ('11-'12) owners, is the normal operation of the car, to constantly switch this button on and off depending on driving destination?

    Has anyone quantified the mpg difference between running with ECON on or off? Say, running a couple of tanks through and keeping the ECON always on, and then a couple of tanks with it off?

    From the limited inputs on several forums it looks like ECON mode gives you an extra 1 maybe 2 miles per gallon. As you say many, at least on forums, experience harsher shifting in ECON mode compared to ECON off.

    I turn it off, except for when I'm on the highway.

    Haven't tracked mileage accurately though.

    Sounds like something that is just there for CAFE standards.

    The Econ Mode changes the engine timing as well as the transmission shift points. It also affects the way the automatic clutch operates in the torque converter.
    You may find the video interesting. 1.5 mpg increase in fuel mileage per government tests.

    The Owner Manual must go into some detail as to how/when to used/what to expect, I would think.

    All in the interest of fuel economy of course, hence the trend toward more transmission speeds like 8 or 10 speed transmissions.

    We don't tend to use it. I don't like turning the 6 speed into a 4 speed. (Which Econ does) We have heavy feet. I think the 6 speed is better with a heavy accelerator.

    "You're not going to really notice it" he says. I think most people on here would beg to differ.

    I must say that I am glad that you can switch it off.

    what i have found with my 2012 grand caravan is in eco mode the shifts are aprox 500-700 RPM sooner and the trans will do its best to get into top gear asap. it also i find will hold the gear its in until you get agressive with the gas. the 3.6 doesnt like low rpm operation, with VVT and multiple valves and cams this engine begs for rpm. mine hates to lug so i leave the eco button off and it performs drastically better with very little penilty in fuel mileage..cheers

    Mine shifts really hard when in ECON mode.

    I actually was aware of it when I bought it, and didn't really want to get it as I figured the transmission was going out.

    I turned off Econ and now it drives like a normal car.

    I still should check and see if reprogramming it would fix it.
