Change dash computer to show mpg instead of L/100miles

Hi all,

New to the forum and been searching around and around...

I have a 2003 323 sport. The hatchback version.

I want to Change the dash computer to show mpg instead of l/100miles... I'm sure there is a way as I've found posts for other mazda models but none for my 323 :-(

Any help will be much appreciated.

wow i dont think most of us even have that feature..ive been around awhile and ive never heard of any type of fuel mileage calculation on a stock dash. you dont mean on a scangauge or something do you?

I think he's talking about making the trip computer show MPG instead of showing miles travelled since reset. I'm not sure of how to do it short of building some sort of computer to calculate that and then wiring it into the stock dash.

That would be pretty sweet! I would love to have something like that, even though I just use Fuelly. Although it would be nice to have instantaneous mileage as I'm peeling out of parking lots and driveways.

Android phone + bluetooth obdii + torque app = whatever dash readings you want to see.

sounds like he's talking about the factory L/100 mileage display in the tachometer factory fitted to some bj's. message The Man he knows more about them.

Hi guys,

Yeah I meant in the stock dash sorry. As in the JDM323J48's picture. The little right hand side read out... Over here we use mainly mpg. Most of my journey is me looking down and thinking... Ok it's says 9l/100miles... That means I'm doing 50 mpg!! Just don't want to keep stressing my ickle brain with the sums!!

Who is 'the man' to message?

Thanks again

I believe the man your looking for is this guy: (it's his forum name)

That's cool i've never seen one of those clusters. I guess they never made a MPH cluster with that display.

I.... um.... kind of.... really really want.

I'm actually glad I don't have that computer readout because here in Canada we're stuck in between all kinds of measurements.

We started off with miles per gallon and we used your British gallon (4.54 liters),... then in the late 70's we switched to the metric system but kept using MPG to define our mileage.

It wasn't until about ten years or so ago that we came up with the wonderful new liters per hundred kilometers to confuse everyone. Now better mileage means a smaller number.

So, why the hell did they have to invert the equation ??? Kilometers per liter makes a lot more sense and you don't have to multiply or divide by 100 to get a tangible value.

I know I get about 13 Km/L and that works well,.. To calculate how much gas and how much money it will cost me to get somewhere, I divide the trip distance by 13,... that tells me how much gas to buy and being as we sell our gas by the liter, I just multiply the number of liters by the price at the pump.


So now,... I guess people have had enough of that L/100 Km crap and the commercials on TV are going back to MPG,... BUT that with your British gallon (4.54 liters as opposed to 3.78 liters) so when I see a commercial on TV I have to check to see if it's an American station or not to make sense of the mileage.

Apparently the new dodge Dart as well as the new Mazda 3 get 59 MPG,... but as soon as we cross the border our mileage plummets. Or does it,... I'm confused, LOL.

At least a mile is always a mile no matter where you are on the planet,... UNLESS you're on the water,... then it gets all screwed up again. (one nautical mile is 1.15 earth bound miles)


I still think you guys are driving on the wrong side of the road. And are you guys still using positive ground on your vehicles ??? My uncle had an old British car years ago with the battery hooked up wrong,... everything worked fine except the clock in the dash was spinning backwards. Just because we found out that electrons flow from positive to negative doesn't mean we have to take our batteries out and turn them around.

P.S. WTF is "ickle" ??? Did you forget an "F" or is that some British slang I'm not aware of ???

Happy with torque app...it can be switched from miles to kilometers if need be.

I know how you feel with the conversions!!! Lol

Ickle means little

Yes the cars are grounded through the neg side of the battery now

And we drive on the right side of the road in every context

My dash... Taken at night but you can see the mph and the consumption display on the right

It has traction control too?!? And it's an MPH cluster, I am very confused I thought we only used the Mile in the US. Does the Odo display miles or KMs?

^^^ what he said (asked)

WTF is that ???

You really gotta to get out and drive that thing,... your roads must be pretty short.

Australia does the mile thing too,... that's where England dumped their prisoners,... I guess they gave them a yard stick and told them what side of the road to drive on.

Maybe New Zealand too. ???

If he has traction control only reason I would think is that he has an awd sport2.0 . Maybe the awd versions got traction control and fuel consumption as options? I think we need more details from op about his car to understand all this stuff

Looks like the USA got the s*** end of the stick as always when it comes to cool features.

Considering all the cool cars the us didn't get are right hand drive I'd say we are driving on the wrong side. Obvious example is the skyline but there's still Sylvia escort cosworth etc

Some Countries still use mph as in efficient as the imperial system is. It would be awesome if we could go metric

The metric system is cool,.. 1 cm cubed is 1 cc,... 1000 cc's is one liter,... 1 liter of fresh water at room temperature is 1 kilogram ,... 1 gram of water is 1 cc

The boiling point of fresh water is 100* celsius and the freezing point is 0* centigrade

If you're stranded on an island with an accurate 1 measured meter you can establish all your units of measurement if you've got water to drink.


AND they are all multiples of ten so the math is easy.

It has traction control yes. The tsc stands for traction control system. There is a little button next to the handbrake to switch it on or off... It's standard front wheel driven 2 litre (liter in your funny spelling!!

This is how our mazda 323 sports come as standard over here on the 2001 onwards versions. But come to think of it my old 1999 323 had traction control too... I guess we got the cool mods in the cars and you get to own guns!!! Fairs fair

The odo is in miles. Over here we use miles.

I only bought 'Maggie' about two months ago... She only had just over 25 original thousand miles.... She's in great condition etc... I paid 1400... How does that fair over in the states and else where? It's about 400 above the average price but she was the lowest miled one I had seen in the uk. I have been looking to get another 323 for ages!! I crashed my 1999 one about 6 years ago... Rolled her 2 and a half times down a country lane and came out with just a scratch on my little finger. Have some pics around somewhere I will upload.

Little annoyed today as I have found some b*****d has scraped the front bumper while I was in a car park!!!!! :-(
