I final got all my gauges through the post from the US, IMPORT TAX FREE again!!

Can anyone give me some advise as to how to fit my gauge ie which probe to tie into and where abouts to tie into the car. It's an Autometer gauge.

cheers

Baz I hooked up the one Brad put into my car, it jumps all over the place because its not getting the right signal. I fear yours may do the same unless its the correct format for the lambda probe...

I remember looking into this loads and it turned out the only way to have an accurate af gauge was to plumb in a dedicated wide band lambda probe for your gauge which was a jaw dropping £300 odd :-o

it will jump form side to side on idle and cruise for example... off gas overrun is red, on gas should be in green.. about all its good for is an indicator on full boost.

wideband is the proper job. narrow band is pants

Can anyone recommend an A/F gauge which will use the LCR wide band sensor accurately.

I've heard bad things about patching it in to the current loom , wrong signals to the ECU etc.

When i do mine i'm gonna fit a seperate boss for another probe into my downpipe , you can get the probes from Eurocarparts etc , there not very pricey.

We have just fitted a wide band lambda setup on a mates Prelude Turbo due to the rubbish readings from the narrowband, now works brilliant.
