Changing L/100KM to MPG?
 

Is there a technique to changing your fuel mileage display from L/100KM to MPG? Even as a Canadian I find the whole metric measurement confusing. I would figure if you can change your speed from KM to MPH then I would think this would be possible, no?

just calculate it yourself when you fill up. the instantaneous readout doesnt really serve a purpose and the average is usually wrong by 10% for me.

You are confused by the metric system?

I'd have a similar request - but change it from l/100km to km/l (which it looks like it can do).

It's just what you're used to I guess. I've always grown up in metric countries, but heights still get quoted in feet and inches.

use torque app

maybe with Toyota Techstream and setup for metric?

L/100KM is just a bad way to measure things, it has nothing to do with the metric system. If I have 12 litres of gas, or 1/4 tank left, I want to know how far I can get with that gas, not how much gas it takes to go 100 KM, because 100KM is just a meaningless number. It should be KM/L which is the same as mpg.

Dimensional analysis, dude. Am I the only one here that passed 7th grade science class?

x L / 100 km * 1 gal / 3.8L * 100 km / 62 miles = y gal / miles

x * 0.00424 = y

z miles / gal = 1 / y = 1 / (x*0.00424)

z miles per gallon = 235.2 / x

So to convert one to the other, divide 235.2 by it.

I.e. 7 L / 100km = (235.2 divided by 7) = 33.6 mpg

or 25 mpg = (235.2 divided by 25) = 9.4 L / 100km

Want a cookie ? ;) I don't see anything bad about it, if it has km/mph for speedometer, why not for mpg.

Has this not been figured out yet?

Way to bump a 3 year old thread

There are 3 buttons on the left side of the gauge cluster, The top one if I remember right changes it.

/end thread let this rest in peace

Changes the speedo rather than the fuel economy readout. It seems to be the most recent thread and better than starting a new one.

Oh I thought it changed all of it including the odometer :iono: but your right bumping old threads is better then starting new ones haha. I just really wanted to post that pic

Still haven't figured it out.

Only way to change it is to change instrument cluster or to reflash its firmware. Either MPG or l/100km is possible (km/l is not possible).

I've been to subaru dealer in lithuania, but they said that its impossible to change with reflash, only way to change it is to swap the american dashboard to european dashboard which costs 200eur if new.
