i have the fuel computer loom in the garage, but have the fuel computer here.

it is gone be connected to a white one. The yellow contact is a fault finder connection.....

roro22

Thanks.
Mine is an H reg and i thought they were standard on the 90's ones?
The guy i bought it off said the wiring was there but he couldnt be bothered with it.
Is i a big job to wire it in?

no, its a stand alone loom actually , some connection to the org loom. but you need some sensors though( speed sensor and fuel sensor) fitted on the gearbox and connected to the meter unit(fuel)

roro22

I was worrying that it had been pulled apart at some point.
Where did you get yours from?
I would like it for authenticity and make a change from the ususal boost gauge lol

did buy the fuel comp from ebay
but the loom i did get when i bought a rst motor for my cab
can take some pics when i am going over there

SafeChav

The yellow plug on the loom is merely the power connection, theres a whole seperate loom to be fitted to run the fuel computer, aswell as needing a couple of sensors.

Do you know if the car has the sensors?

I have a complete fuel computer setup, you have PM

Alex_86

iTrader: (2)

no i dont have pm
hm do u have the sensors? i need them

and at the last.. u just re-wright what i did wright

SafeChav

No not you, you plank

Indeed i do have the sensors

I have thought about this before... but how accurate are these (when working correctly) ?, I mean what sensors do they use to obtain the MPG etc.... ?

My car is currently averaging 33.4 MPG at the moment, but say for arguments sake I had a big upgrade (new head, turbo, injectors etc...) would it still calculate the MPG correctly (ie the amount of fuel going through the now bigger injectors) or would it knock it all out?

SafeChav

It compares the fuel flow rate to how fast the wheels are turning, so based on that it should be accurate.

The range feature however is particularly piss poor, mainly because of how the sender is mounted in the tank, drive down a hill and all of a sudden you have gained a LOT more miles before you run out of petrol according to the range

Drive up a hill and all of a sudden you've lost all your petrol and have 0 miles

JimmyBoy

Interesting.

The range seems ok on a flat, but as you say about the hills it goes a bit tits up then.

If I fill up, it will say on the range about 340 miles (I think) and I usually get about 320 miles to a tank, so quite close.

SafeChav

The range function compares how much fuel is in the tank to the MPG your doing.

If you drive the car eratically you will also find the range figure is wrong because it keeps a log of how the car has been driven over a period.

My mum had a Mk2 orion may years ago and it just got annoying when it used to beep telling you that you had 0 miles left when there was loads of fuel in there

antony215

Imo all there good for is it looks pretty ive had them in the last few cars ive had and ive disconnected them in all because of the constant fucking beeping even when you have a full tank and the one that was in the RS ive made into a gauge holder

SafeChav

Personally i think the economy and fuel used functions are useful, you should of taken it apart and disconnected the sounder

antony215

If id have known how much they made on ebay then i would have took them all out with the looms and sold them on there

I remeber a mate of mine had one in his orion it told him he could do another 100 miles with the fuel that was in his tank (bearing in mind he was on the red ) he got about 15-20 miles and run out of fuel

andyorion

I run a modifed 1.6 cvh turbo in mine, which due to some engine work I am currently running in. At the weekend I calculated the fuel consumption I was getting using miles covered and amount of fuel required to fill the tank. I then compared this to the reading the fuel computer had which I had reset at the fill up prior to this and the mpg reading I had on the computer was 0.9 mpg out from the mpg the car was actually achieving. Which imo I didn't think was bad for 80's Ford engineering and to use as a rough guide. Also I tend to refuel the tank before it gets below 1/4 and this means the fuel range is normally above the 50 miles that it starts beeping from to remind you to refuel.

ok,if u get it on my door in 30min

SafeChav

andyorion i dont rate those flow sensors, IMo they have a lot of room for being unaccurate due to the nature of what they are, but i agree for the age of the technology it cant be bad, its just a gadget at the end of the day though isnt it

Alex_86, delivery is extra..............

Alex_86

iTrader: (2)

30mins is loong gone but say if u got some extras for sale mate

andyorion

Yeah know what you mean, I don't mind it, perhaps if it didn't work I wouldn't think that highly of it...... I would probably repair it
As with anything on the car it has to work its just the way I am

JimmyBoy

How do you disconnect the sounder ? It does get fookin annoying going off at 50, 25 and 10 miles on the range reading!

SafeChav

I cant stand having things that dont work either

cristiano_iglésias

hello friends, where can the fuel flow sensor?

RSmark84

....Huh?

cristiano_iglésias

I have a mk4 convertible and am installing the fuel computer and already have the speed sensor and the lack of such a fuel flow sensor, would like to help where I can find it or if a friend has a forum to sell me

RSmark84

Ah i understand. Your English is quite good compared to 50% of the English people that live here!

Your best bet really is Ebay, or trying the for sale threads on here. These Fuel computer parst are quite rare these days, expect to pay good money and someone willing to sell outside the UK. I will have a look around on Ebay for you.

cristiano_iglésias

Oh god, thank you so much in fact that I only need the fuel sensor fuel, already searched everywhere on the net and would like to at least know what the looks of it if you can help me thank you very much

RSmark84

Nowt pops up on ebay, but as i said they are quite rare. Am i correct this sensor fits onto the metering unit?

Anyway have you tried the XROC forum. They were fitted mainly to these models, more so on the cabriolets.

Heres a link about the fuel computer on XROC..... maybe your best bet. Sign up and ask them.

RSmark84

Nope tried google and searched ebay for every name i can think off, remember they were fitted to Ghia models too, just to widen your search.

cristiano_iglésias

then, my escort is from Brazil, is an XR3 1.8 carburetor, so I researched and gave a friend dai was helping me with this is as follows:
the fuel computer is on the panel (already bought on ebay) ai him I have to connect a wire to speed sensor, a positive in a key post, ground a float in the fuel tank and in such a flow meter fuel, what I need is this guy flowmeter fuel, the rest I already have everything up to the installation scheme that a person passed me daimuito helpful.

RSmark84

The speed sensor and the fuel tank sensor will be fine fitted but i cant see how the flow sensor would fit as that was fit to the fuel Injection metering unit, it should be a red nylon pipe coming of the upper bit of the fuel lines.

cristiano_iglésias

where can it? there is certainly easier to get here in Brazil doque here simply because there is no escort rs kkkkk
will you help me wondering maybe there in the forum to class? I will be very grateful and I will soon post pictures of my white angel

RSmark84

ok i forgot the link

thanks again

cristiano_iglésias

hi, I was looking for and found it here https://passionford.com/forum/ford-e...-computer.html see the fourth photo, this photo is no accident that the flow of fuel sensor?

boeb

wot kinda cash is in the full set up for this.......and wots in full set up...gauge ..loom..metering unit pipe bit and gbox sensor ?

cristiano_iglésias

I have everything already, just missing the FFS fuel sensor flou not know where to find
