Hi all,

Very new to gas systems but just bought an ex-taxi with new motor. Well 92000 km old so not new but better then 600000 km.

I have since filled the car with gas after its first fill up and found that I am getting 4km to the litre. There was a thousand stop starts in there which explains a decrease in milage to the gallon, however the numbers suggest the system requires a tune.

I have identified a bolt designated BAL (left hand side), Two allen key screws in the top (one deisgnated R idle), a bolt with a spring plus a bolt on the left side desginated L (set a little to the left of centre at the moment see pictures).

Anyone able to help me with the tuning procedures on this unit? The engine is a EFI 96 Model Ford 4.0 litre which I believe manages itself but the gas is its owns beast.

The screw with the spring is the idle controller.
The knob that says L and R (Lean & Rich) is the mixture settings, run it too much on the L side you risk back fires
Try running it in the middle and go for a drive, and keep moving the knob either way until you are happy with the power/throttle response.

If its too lean will have no power up top
If to rich will struggle to get off the line

Its a bit of trial and error to get it right

My ex-taxi had the impco processor on the strut tower, passenger side.

Also D/s kick panel, or under the seat...

Being a taxi you might even find it on top of the dash mate

the fcv's are s**t and on my cars barely work properly..

I could not get mine to run properly intil i replaced the diaphragm in the mixer...u can get differently callibrated ones...

originally mine was running around 10:1 A/F now its around 12:1...still not right but much better...the adjusters dont do much when your miles out to begin with
