Just a couple of things I've noticed and wondered if anyone else thought the same:

1. When stopped at the lights, if the engine switches off, then the MPG readout is correct at "--.-" and the red efficiency bar shows "maximum". However, if the engine is idling, then it *should* be "0.00" MPG because that's what it's doing, and the red efficiency bar should be at 0. I am sure my E36 gauge used to do that, but my E90 didn't.

2. Should the red bar be green? I know red matches the rest of the cars colors etc, but I keep looking and mentally think "more red = bad" when in fact it's not.

I guess as a developer I like visual indications to be concise, and especially the last one I feel is visually wrong from what most people would expect.

I'd have to double check but my E46 shows the MPG needle being all the way to the max.

I had to think about this for a second. if your car is built for the us then your right. the higher the red bar the better as you would measure miles per gallon but if your from Canada its measures liters per 100km. so you would want the red bar to be low for fuel efficiency.

Interesting - so in New Zealand, they might do the same thing?

In Eco Pro mode (with an MT6) I find it pretty much useless - I cannot drive staring at that gauge. Kind of disappointed that it's not put into the HUD where it could actually be useful.

When idling? That's what my E90 did, but I'm sure my E36 used to show it as 0 at idle which is correct.

Yes when idling.

When you're stopped you're at 0MPG since you're consuming gas, but not moving. That's why the system is calculating 0, and therefore you're losing your MPG. -- After you reset your trip computer, watch your MPG go down when you're at stop (idling) with A.S.S. Off.

My e90, e70, F01 all does that. That's why leaving on the A.S.S help you on saving gas.
e90 for instance, the as you come to stop, the needle goes all the way to 0 then at complete stop, it bounces to max position (although it's really at 0 MPG)

Yes - but in my F30, it shows "--.- MPG" and the scale goes to max, it does not show "0.0 MPG" with the scale on 0 as it should. I know you're at 0MPG because you're idling stationary, I'm saying the car doesn't indicate that.

It's probably to make you less depressed.

It should say "Turn ASS back on you dummy you're killing the planet and wasting money"

As far as the red bar vs "green" that is actually more related to the human factors of how the cones of your eye respond to light. Red is the least impactful, which is why BMW goes with red/amber throughout the cabin. Greens/blues force your eye to adapt more which hurts night vision and would start to bother you over time.

Yeah - can understand about the re/amber. Same reason aircraft cockpits have red/amber lighting at night. Maybe I just need a Canadian version that reads the other way so "more red = bad" would be the correct way to read the gauge.

Just noticed I can change the economy readings to be l/100k so it's now reading as I would expect

Being from NZ, I'm more used to l/100k anyway.
