Hi guys,

Im going to be installing an air fuel ratio gauge into my mini tomoz, and the fitting instructions say that i have to connect the 1 wire that is coming out the back of it to the o2 sensor coming out/in to my ecu. now as i havent got an ecu, any ideas on how i can get this to work?

Cheers

you need to fit a lambda sensor into your exhaust system.

as above

what a/f gauge did you get?

[Shaz_mini_Beast]

Its an auto gauge, gauge lol. so if i fit a lambda sensor in my exhaust and just connect the wire to it it should work? in theory.

should do, if its a narrowband setup i wouldn't bother though personally.

I have this set up on mine and the narrow band works fine as a rough guide. It has helped me get the correct needle a whole lot quicker.

cheers guys.

A narrowband is better than nothing, but a wideband is far superior. There's some info on wiring the narrowband here: Air/Fuel Info.

any idea what cars are fitted with a single wire lambda so i can hack one out
