    Mitsubishi recommended up shift speeds

    In the 2015 owners manual on page 5-38 and 5-39 there is a chart with recommended up shift speeds for "the best fuel economy and performance in using your manual transaxle".

    They are as follows:

    Acceleration conditions:
    1st to 2nd- 15mph
    2nd to 3rd- 28mph
    3rd to 4th- 36mph
    4th to 5th-45mph

    Under cruise conditions:
    1st to 2nd- 15mph
    2nd to 3rd- 19mph
    3rd to 4th- 33mph
    4th to 5th- 45mph

    How accurate do most of you fellow efficient drivers find this to be? I must say that I find shifting very smooth at these speeds and their corresponding rpms, even for "cruise" conditions. The acceleration end to me seems to be winding out 2nd a bit too far.

    I tend to skip gears when I can, most often skipping 2nd to 4th or 3rd to 5th. Will that get me a bit better mpg or would running straight through the gears as instructed be best?

    I almost always run all the way through the gears when accelerating. I also drive for efficiency. Keeping the engine in its minimum BSFC (brake specific fuel consumption) is best. However, there really isn't a big penalty for revving it up a bit more or less.

    As I read on ecomodders it's not the higher revs so much as the sudden stops in speed and going over the best cruising speed. I think on flat land my mirage does best 45-50mph in 5th, but with the hills here 55mph is a little better to keep it from bogging on steep hills. Accelerating onto a interstate at 3-3.5k vs 2.5k isn't going to help much and create a hazard if it's busy. Driving stop light to stop light at 3.5k shifts will hurt fuel economy, when you know there is a potential to slow down or stop (traffic lights ect.) then driving slow and easy is the best choice, it's all about driving smart and knowing when to use the power and when to drive easy.

    Are either of you aware of more specific info on the deceleration fuel cut off?

    Do the injectors stop every time the throttle is released during a coast?

    The european spec Space Star 1.2 tells to shift back under...
    31 kph in 3rd
    41 kph in 4th
    46 kph in 5th gear.

    So I shift up at...
    15 kph in 2nd
    30 kph in 3rd
    40 kph in 4th
    45 kph in 5th gear...
    and shift down at the same speeds when I need to accelerate again.

    If I don´t have to accelerate, the car can roll at...
    10 kph in 2nd
    20 kph in 3rd
    30 kph in 4th
    40 kph in 5th gear.

    I don´t drive fast and accelerate hard, so this is the most efficient way to drive.

    I think you are missing a decimal point on your last fuel log entry. The tank will not hold over 300 liters. Our shift points are almost identical.

    Does it not irritate anyone else that they used MPH and not RPM for this?

    I could never lift and speed shift this thing like Ronnie Sox and hit all the MPH numbers they want, and I guarantee it wont be the most FE way... lol

    On my manual it seems like dfco works when downshifting down to about 1200 rpm. Not sure about the cvt.

    it did at first, but now I am really getting used to the speeds.

    to make it easy, I made my shift points 15, 25, 35, and 45.... or just whatever the hell I want depending on the scenario, there has been plenty of times where 25 won't carry me into 3rd and I have to wind 2nd out a bit longer, for example.

    I typically shift between 2500-3k, but I'll wind it up to 4k in first and second if I have a passenger.
