i understand what your saying DARTHVADER, with the btr 4speed, the torque converter lock up does not add any initial gears, buy locking up it is essentially holding on to fourth with out the torque converter being used, leaving no slip, a good way to understand how the torque converter works is bring the car to an initial stop, put the foot on the break and stall it up, it should stall to about 1800-2200rpm, let off the break and the revs wont drop. when in gears 1, 2 or 3 the torque converter is stalled up slightly when accelerating to make acceleration and shifts smoother, when in 4th the torque converter wont do this it is a fuel saving thing.. having the button on econ or normal will not have any effect on this..

the econ and normal switch is very basic, and does only what i said it does in the previous post.


So......what i said was right all along or not???
WILL he get better fuel economy (slight as it may be) in ECO mode with an AUTO?????
Is this not the question that was raised in this topic or not???

I am in disbelief that you believe that if a car revs harder in POWER mode you will get the same fuel economy as with it in ECO mode!

if your doing 1500rpm at 100km/h theirs something wrong with your speedo.

DARTHVADER your mistaken, if that is so then theirs something wrong with your car. if you were still in third at 100km/h you would be revving over 2500rpm,
you realize if anything the torque converter locks up earlier in normal mode compared to econ, and when in econ mode its less happy to down gear, making normal mode more economical when cruising..
either way theirs a wombats piss difference between the two modes if driving mormally


Hi again 4dlvr.
I think what i am trying to say is that the Auto shifts all the way to 4th....at say 100kmh i lift my foot and settle in for a trip. Now shortly after that a (a few seconds maybe more) so long as you hold your foot steady. The engine will drop a few revs again. Like i said earlier only a few maybe 100 or something. This i have been told is the Auto locking up the convertor, basically giving you an extra gear.
When you are in POWER mode this action does not happen. So your revs are up slightly.
Hope this helps you understand what i am trying to say.
I have spoken to a FORD mechanic on this he explained that way to me.
I have driven 2 other AU S3 I6 an the autos behave the same. I have no knowledge of the workings of earlier Autos in the falcons IE: E series sorry. But can find out.

power/econ button makes no difference to engine revs @ 100km on my AU2
driven properly i can return the same fuel consumption in 'econ' and in 'normal'.

not trying to be a pain, but my ED sits just over 1500rpm at 100 in 4th, just over 2200 in 3rd..
and around 4000 in 2nd :twisted:
the speedo is fine too


no way is your speedo correct if that is the case. With a 3.08 diff, around 1850rpm@100 in top with the converter locked.



Just took it down geelong/melb freeway past the speed checker things and it said I was doin 98km when my speedo was on 100.. Gps says 98-99.. Got a pict of the speedo/tacho but can't attach it??
No idea what the diff is the car is a stocker apart from ea intake tube..


Anyway,

Darthvader, if your just driving down the highway at a constant speed it shouldn't make a difference, the only thing the normal econ switch changes is the shift points when your acellerating.. I believe that's what should happen anyway
