Dragging... 'Power' or 'Eco'

[Vision Zetec]

thanks guys

sometimes when it is changing gears under about 40-60% throttle it will rev up higher to change gears and then clunk into the next gear.
iv been told it is a ford thing, is that right?

cheers

i say use power but i always go in eco coz i forget to switch

Yep thats a 4 speed auto deal, it sucks damn electronic auto

(update your sig to include Fairmont ghia Doortrims)

My auto in my leb spec EF futura holds gear at 5500rpm in Power and shifts at 5000rpm in eco.

edit- i am in saudi though i had my ef imported. does it make a diff if i'm in a nother country?

No, country does not matter. Hemisphere does

power button will not make your car faster unless u hook it up to a bottle of nos, all it does is hold the car in gear for longer, and if u cant tell when to cahane gears if u do it manually (which is what u should b doin if u dragin) you shouldnt be drivin a car at all.

mines alot more responsive on the highway when putting the foot down in power mode...but then proceeds to flare its *** off...hopefully a shift kit will get rid of that

I'd love to know where you can find information like that....

IIRC Ford Factory workshop manual figures right there. Heck i think there's even information to that effect in the glovebox manual.... or was it max ellery?? i dunno... but ive seen them before.

Let's also consider line pressure. Similarly to shift points, line pressure at WOT is not much different between power and econ (compared with difference in LP at lower throttle) - but it is different. So if you plan on experimenting with pwr/econ, at least fit an S5 mod so you minimise the shifting time in econ mode.

my ED is a manual which i suggest to all who want to drag but in my bro's auto EA there is no real noticable difference bw power and eco at WOT

[CruizinEB]

What differance dose it make??

[EA2BA]

I have mine in power mode 24/7 and I use 1-2-3 as well, well with a BA shifter installed what else would I do

I work at a New Ford Car Dealership and looked into this with a few of the mechanics. Apparently the ECU is specifically set to a max rev cut out. All the PWR switch does is holds each gear longer, allowing more revs to be built up, with reduced pedal travel. At complete open throttle it will hold the gear to its max rev cut out regardless of whether your running in PWR or ECO. The variations in performance experienced by some of you may simply be due to a poor throttle cable/kickdown cable calibration, meaning when you think the accelarator is completely depressed, the butterfly may not be completely open, hence the additional performance when in PWR mode, because it holds the gear longer.

Not according to the BTR/Ford specifications, I am being a bit picky here becuase the difference is only small but there is still some difference. ANd yes the EEC is rev limited but with the auto it is difficult to get to that limit unless you manually hold the trans in gears, the auto is programmed to shift a fair bit before the rev limiter.

Basically in PWR mode, the trans will hold in gear longer at any amount of throttle however the biggest difference is at around 50% throttle.
