The power button changes the shift point settings on the auto so that it shifts at higher rpms. This helps so that if you're towing a horse float up a hill, it won't change gears too early & bog the car down.

Personally, I wouldn't bother using the power button unless you're getting the car dynoed (so it holds onto a gear a little longer) or at the lights

Driving around town with it on just means you go thru more fuel, and the car doesn't really go much quicker (if at all).

Power button changes when the transmission shifts gears. It will still shift into overdrive (just called 4th on the Falc) but it will do so at a higher speed. If you don't notice a difference when u switch between the two then perhaps somnething is amiss. You should see/hear the engine rev higher in each gear before changing.
I've been told by a mates mechanic that the Econ button also somehow reduces the fuel consumption of the engine during normal driving in a way other than shifting earlier, but i dont really believe this. Considerable 0-100 testing y mates showed that little difference occurs (less that 0.1 seconds) between power and econ with 100% throttle.
Probably didnt want a life story...but u got it anyway....

Yeah A/F ratio might be richened a little in Power mode? It's not like it needs it! Factory settings are pretty rich to begin with...

The main noticable shift point difference is when you're doing 1/4 or 1/2 throttle. Instead of shifting at 2000-2500rpm, it changes at around 3000rpm instead. I don't need my power button any more though, I use the tiptronic to decide when to change gears 6000rpm@WOT sounds mad!

I have a EBII, and read in the newspaper that the power button will actually save u fuel. I thought i'd try it and blow me down , it worked. I now get approx 40 km more per tank of fuel.

that's interesting and might consider experimenting with the button, i never look at the button unless some smart ass holden girl wants to go

although keeping the car on power mode (econ off) is better for your transmision as it doesn't constantly change gears etc...

uhm... really? What is your basis for this comment? I would have thought
it would make no difference to the longevity of your gearbox etc.

Technically it may be correct as when you are in economy mode the trans will shift a bit more. This is because it will select the next gear (in particular 4th) much earlier so if you are criusing around want to accelerate it may have to shift down another gear etc. Don't really know if it has much effect on trans life though.

The power button only changes shift points, the EEC itself has no idea if it is in power or economy mode so won't alter fuel or timing between the modes. IMO the power mode setting is far more noticable in the V8's.
