air/fuel ratio meter

[sooty43]

Many years ago my mechanic used an a/f ratio meter to tune my auone. I have just had one built for me and I would like to know where under the bonnet do I plug it in? The AU is late 99 model.

For it to be any good you'll need to add a wideband sensor and controller to your car.

If you are interest in if its running lean, rich or stoich and dont care how lean or rich then wire it into your current gauge at the ECU. It wont just plug in.

Hi Sooty

As Dan mentioned, you will need a wideband sensor and at minimum software, or a gauge to monitor it. Great timing, as I have just installed a wideband into my car, replacing one of the narrowband (right bank on V8) sensors. I highly recommend an Innovate LC-1.

or as a kit with a gauge

Plenty of options on their website - check them out. Sorry, it is not as simple as 'where do I plug it in'.

Good luck
