 |
|
I was told by a transmission place that if you keep the power/economy switch in power mode all the time it can damage the transmission and use alot more fuel......Does anyone know if this is true or not?

I don't get how using more fuel damages the transmission.
I've heard that it's good to leave it in power mod under 80km/h because the transmission will hold gears for longer meaning that when it changes gears less strain is put on the driveline... |

for once twr84jdlsex I agree with you  I drive around the city with mine in power all the time for that exact reason, it holds a gear a bit longer and doesn't "lug" the transmission up a hill in to low a gear. Then when I am on the highway I put it into econ.
And no I do not have it in power to drag off at the lights, I drive like an old man and find in econ mode it can't wait to get into 4th even when I am going slow.... |

| Ive heard economy mode will do more damage as he trans spends a lot more time in OD which apparantley puts a bit of wear and tear on there. |

| well, i can't really sit with mine in power mode - it really mucks up the revs with my stg 2 cam. its sits too high in power mode at certain speeds, so mine sits in economy pretty much 24/7... |

I keep mine in economy just because the difference in pwr is amazing. Kinda like a novelty, car goes so much harder with econ off. Keep it for special moments  |

| Shouldn't really use O/D under 80km/hr. Yes it does put more strain on lockup convertor as the motor will bog down to much, as it's sitting to far under the torque point. |

I find that my car is quicker (better going sounding better) in economy quiite weird, my theory is; LPG in my car creates lag at high rpm gear changes (in non-econ mode) it will lag when changing from 1st to 2nd. I find that it won't lag in economy just a smooth shift.
A quick tune up of the LPG system will fix this and help it lag less.
Just my 2c  |

Something else i thought i may add. The a/f ratio in od vs a/f in 3rd (i have pretty lights to watch this).
3rd gear at 60km/hr the a/f behaves as it should - swinging quickly from rich to lean as EEC attemps to average on stoich.
4th (o/d) at 60km/hr EEC struggles to achieve a decent stoich mix as the engine labours a little at those revs (1400 odd rpm in a V8 auto with 3.23 gears). Characteried by unpredictable swings from rich to lean, spending a lot of time in quite a rich condition. |

| This is all speculation, as to this data I have found no data regarding this theory nor a tranny dying just because it was in Economy all the time. If it was that bad, Ford wouldn't use it. You are more likely to kill the tranny in many other ways than using the Eco button.. |

So modify the electrics to enable the torque converter clutch to lock up by a switch when you want it.
I wholeheartedly agree with One Drone here. Someone prove it, not your brothers uncles cousins second father said so.
Besides, even if it is true, wouldn't it be a good thing to kill as many auto's as possible and have a manual bolt in its place?  |

I get better fuel ecconomy with econ off. Its almost worth about an extra 25-50km a tank.
Car is more fun to drive too. |

I also have the oxygen sensor that has three wires (im told there is variations) and have a lean/rich LED indicator from jaycar - anyone hooked one up b4??

its simple as ppl said.
it makes your car rev out a bit more and respond to the pedal a bit quicker when your accelerating around the place in comparison to it off.
for exchasers (mine) it makes a difference overall as it shifts harder (shiftkit solenoid in the box) then normally and also my ecu only goes into OD (overdrive/4th) AFTER 65/km ..
And reaosn you get better milage is the car is NOT supposed to pop into 4th/overdrive anytime it feels and realistically you should have it in 3all the time unless you go over 65, lucky for me having exchaser eh? .. been told this several times by auto tranny places .. |

I like to prove things for myself. I find the ford auto economy shift pattern is designed for maximum fuel economy, and it achieves it in my EL barge.
How others get better economy out of leaving it in power, I cannot explain.
Install a trip computer and leave it on instantaneous fuel consumption. You'll find that fourth gear is fantastic for puttering along at 45-60km/h on a flat road, it uses around 20% less fuel than leaving the box in third. I've confirmed it too, by not trusting the trip computer and driving it in third on all roads that are 60km/h. Guess what happened? I only got 300km out of a tank of gas instead of about 380km (this was done before the torque converter lockup clutch mod which improved economy by another 20% again) |

Over the past 4 days I have been driving around with the power button on and I have to say that it feels more alive.......But it's using so much fuel.
15 litres only gets me a mileage of around 85 K's and thats when I'm driving carefully.
Can anyone tell me if my quoted mileage on 15 litres of fuel sounds normal? My car is a EB 4.0 auto.

| I find the power mode very effective when towing - also puts less strain on the drive train. |

| Yeah I'm leaving mine in power for city driving, I can't resist - its too much fun. But the fuel economy is s**t. About 17-18l/100km. Although I can't be 100% certain it would be much better in economy. |
