**** me, the gain between CFI and MPFI is massive!

How does the car kick down at 60km/hr when you stamp out the pedal. My cfi would go quite well but from 0-60 it was fairly gutless. MPI has changed that. Drive a mpi car whether an EA-ED and compare the power differences. When I drove my dads EB fairmont work car i noticed an instant power increase just touching the pedal. After doing the conversion my car had the same feeling, so i knew I had done it right.

Cheers Luke.

My CFI Falcon is fairly gutless all way round and its bumming me out.
I really crave more power cause I'm so used to driving my previous car which was a VS Berlina and that was fast, it was only a v6 auto but if I planted my foot down I could get wheelspin happening.
I'm thinking of getting a uni air filter and new exhaust system installed in my Falcon.
Also thinking about switching over to MPFI but I seriously dont have a clue how I would do it, I've asked around also and cant seem to find any places that can do it for me.

Anybody have any suggestions?

Thanks!

Yep! Do it yourself! A million and one tutorials spread across these forums. Do that before anything else.

BTW, what happened with the VS, if you don't mind me asking?

Were are you located?? Your not gunna find any mechanics that are willing to do MPFi conversions, and if you do, they'll charge a fair bit. Do the conversion yourself, as Xrated said there are many topics on here covering this. The parts shouldn't be overly expensive either (from a wrecker ofcourse), around the $250 for a 20kw increase in power :)

Once you install MPFI, it'll open a whole new area of mods that you can explore...

Also, you can look into things such as a shorter diff ratio. Since yours is a 4 speed, your not limited as much as if you had a 3 speed, and could prolly go pretty high, but your fuel economy will go down.

Before you go heading off with MPFI conversions, exhausts, uni filters (sic) diff changes and all, that crap, make sure all the basics are working properly on your car.

Plugs, leads, filters, timing, cap & rotor, injectors, fuel pump, battery, cooling system, exhaust, clean terminals plus loom and wiring connections may not be sexy, but if all the basics aren't working correctly, getting into add-ons are just like painting a greasy wall.
And make sure your tyres aren't half flat as well.

I had to write it off.
Story cut short, basically was driving home one day from work and the sun was in my eyes. Could hardly see a damn thing, next thing you know theres rubbish on the road like bricks or something so I dont know why but I suddenly swerved to try and avoid them without thinking.
Lost control and ploughed straight into the curb, spun a 180 and the front end smashed into a tree on somebody's properly.
I was unhurt but that was some scary shit! People came out and had a look some helped me but there really wasnt anything I could do.
The bonnet had caved in so I had to get it towed away. The tree was okay though only had some bark taken off it.

Anyway, with the Falcon first I need to confirm something with anybody else who has a CFI EA Falcon.
Does it take you 9.7 seconds to get from 0-60km/h???
This evening I took my car out and timed myself on an open road from standing still to 60km/h and that was painfully slow!
My friends Daihatsu Charade can do 0-100km/h in like 15 seconds or so.
There either must be something very wrong with my Falcon or the 3.9lit CFI motor is just rubbish.
I didnt bother trying to time my car doing 0-100k/h but can anybody else confirm whether their falcon (similar to mine) is as slow?

Rawlinna, if you bothered to read the post he has done almost all of the things you listed.
Well mate..
Sometimes it's just too tedious to read through pages of waffle to maybe pick up the odd relevant sentence.
And from experience fixing a lot of young guy's cars (not all, but many.. and to be fair, it's not always young guys) they are looking for one magic bullet to fix their car when in fact all the mundane basics have been neglected.

Hey guys, well I havent given up hope yet. Took my car back to the mechanic this arvo and told him that my car drives like poo so he took it for a test drive and told me that there's a good chance the engine timing could be out or something along those lines and there could also be a good chance that the catalytic converter is partially blocked.
So I got the car booked in again for monday.
Hopefully this will be the answer to my troubles.

As for switching from a VS to an EA CFI... the power difference shouldn't be that spectacular should it?
I mean we are looking at going from around 142kW to 120kW right?
The weight difference wouldn't be the big either.

completely different tho, a vsII is faster than my ea MPFI (and as far as I can tell this is normal?)

I own a CFI EA and my gf also had a vsII so i've driven both plenty of times...

The outright power difference isn't huge (i think the cfi has better torque or close anyways), but in terms of acceleration the commo's 1st gear ratio helps considerably. And so makes the car seem much faster and more powerful than they are.. Especially compared to the ratios of the falcon.

But I am 100% sure that it doesn't take almost 10secs to reach 60km/h in mine. And I also think I had a blocked cat and its sucking some power.

Yep gotta agree, in my opinon, i rekon the engine aint breathin properly.
Stick ya head under the car and listen for any hissing that could be coming from the exhaust other than the end its supposed to.
If gettin the cat and muff checked for blockages comes up negative then the power issue has got me stumped after all the other things you have gotten fixed/checked.
Before i got my EB II 5 spd, the old man's car was an EA fairmont CPI 3 spd, and to tell ya the truth it wasn't that gutless even when on gas.(Had no probs spinnin its single spinna) But the sad truth is that MPI is the way, thats why cpi was phased out.
P.S. The Ea did have the temp fluctuating problem 2. Even after it was flushed by the mechanic.....Problem = air bubbles cruisin through the system, Solution = needed to be purged/expelled by a simple process explained in the gregories manual.
GET THE GREGORIES MANUAL....its the ford owners holy bible.
Cheers,

Yes. I have an EA 3.9 CPI (dual fuel - Impco LPG system).
Until recently, it ran just fine, but suddenly became gutless. The engine revs freely and smoothly in P position, but once "drive" is selected, there is little pulling power. If handbrake is applied, the car won't move an inch, and engine stalls whilst increasing revs. This is the case when running on petrol or gas.
Distributor and module were recently replaced by a mechanic. (some time before problem arose). I replaced MAP sensor, to no avail. Ignition timing is fine. Throttle cable is fine. Plugs are fine. New air filter. All hoses fine.
My guess is that the 3 speed trans has gone south. (either bands or torque converter).
It's wierd. Apart form the severe lack of power (which happened without warning), everything else checks out ok. Car runs smoothly, and doesn't stall under normal takeoff, albeit a SLOW takeoff! (Steep hill takeoffs are almost impossible!) However the trans doesn't slip at all, the engine just labours)
I've heard that the 3 speed trans is bullet proof.
I will take it to a trans specialist to get the bands adjusted and see what happens.
Like the original poster of this thread, I am at a loss.
Cheers.

How's your vacuum and fuel pressure. Also sounds like a plugging cat could be the culprit as well, but less likely.
