wiring up air/fuel gauge?

[graham_172]

anyone know the wiring layout on the lambda sensor? can't find any answers

Should only really have 4 wires? 2 for signal and 2 for heating. This the standard lambda? Surely an AFR guage needs a wideband lambda?

 

[graham_172]

instructions were not with gauge. only needs 1 signal wire connected.
auto gauge one

What would be the reason for one of these on a standard (ish) car ?

 

[graham_172]

not very standard but to monitor air/fuel ratio when on full taps. easy indicator as to leaning out etc. I won't go into details of modifications but something pipelined for other members soon hopefully.

Sounds good.

But..

..unless you have a tuner box, there isnt really a lot you can do yourself even if it does register running rich / lean
