Hi All

i have a 1988 van fitted with a s2 engine,is it possible to fit a air/fuel ratio gauge as the van doesent have Lambda sensor?
if it is possible please could someone explain how?or what bits i might need?
Have the gauge already made by autogauge

many thanks
pete

 

Indeed it is, but you have to buy and fit a lambda sensor.

You'll have to spend a good couple of hundred getting a good air/fuel monitor though otherwise its not worth it

 

Thanks for the reply bud,
so if i brought a lambda sensor (for any ford,do they do one for the s2 rs turbo?)
I wire this straight into the gauge? i was told it was not possible as my ecu wouldn't support this kind of read out?

 

If you're only installing a gauge it has nothing to do with the ECU itself

HOWEVER, as i said, a cheap air/fuel ratio gauge is useless, as they are not accurate.

You are looking to spend at least £250 if you actually wnat what you see to mean anything and/or be useful in anyway

You need a wideband lambda, a controller, and a monitoring device that will accept the wideband signal.

 

good advice, Andy.....mucho impresso

 

heres a very good web site to look at for the right bits

i'm not really worried about correct readings,brought this gauge and cant take it back so seem a waste just sat in there,just want it to work and fill a hole in the dash!

was looking at a one wire lamda sensor? fixing this and the connecting to the signal wire from the gauge,would this be right?
thanks

 

Thats fair enough, be aware though the gauge won't show a consistent reading, it is normal for the gauge to skip backwards and forwards because of how the narrow band lambda outputs its signal, its basically a switch (not very good)

A single wire lambda will be awful as it hasnt even got an internal heater

 

thanks guys for all the info

three wire sensor at least then?

 

check the gotech website , download the manual , it has a section on this
i had hassles getting a 4 wire sensor to read , fitted a three wire to an autoguage meter and it works.grey is signal?(cant remeber) , one is pos wired to ignition , one is neg
not accurate , but when it says lean , listen.Ask my number three ring lands!
got a fitting from a hydraulic place , used an angle grinder to grind the front of this "nut".drill and weld , fit and away you go.
from what ive seen from turbod golfs etc , this needs to be fitted as close to the turbo as possible , but not so close as to melt it

 

You want a wideband sensor, nothing else. Not a 1,2,3 or 4 wire sensor but a Bosch LSU4 sensor. Think it has a 6 wire connector. The sensor is cheap at around 40£ max, but it need a driver and a display. Around 200£ total at very cheapest. All other type sensors are only good at tuning a engine optimally for a catalysator.
