A/F ratio gauge install

DMRK · 09-30-2007, 07:26 PM

Has anyone installed a A/F ratio gauge in there car?

I am going to install an autometer A/F gauge in my car using a single gauge pillar pod and was wondering if anyone else had done anything similar.

Where would be the best place to get to the O2 wires? DME maybe?

Just run 'em up under the dash, through one of the firewall grommets and tap/splice to the O2 sensor wires from there. Easy & simple.

They have a single or double. I bought a universal single pod for $15 on ebay. I think I can make it look good, I'll post pics after I get it done. Hopefully it will get here this week so I can start.

Change in plans.
I decided I wanted 3 gauges, so the A-pillar wouldn't work. So I used some aircraft aluminum that was leaning along side the fridge in the garage to make a panel to fit below the radio. So here it is before the gauges.

Very nicely done! Please post pictures after the gages are installed!

I must ask though....what made the aluminum you used "aircraft aluminum"?

Are you thinking of using the stock O2 sensor signal? I thought you had to use a dedicated aftermarket wide-band O2 sensor for those gauges...

Mine is fitted w/ a Halmeter A/F meter and I used the DME side of the O2 plug placed the wire in the plug and one to power/grnd. But mine may be different than Autometer.

I guess it would be the composition of the alloy which makes it aircraft aluminum. It is just commonly used in the construction of airplanes.

Also the gauges are available in narrow-band or wide-band.

Many times when you hear "aircraft grade aluminum" what you are getting is either 6061 (common) or 7075 (not as common) alloy aluminum. Other than being used in aircraft (and tons of other things) there is nothing that makes them special. 6000 series is alloyed with magnesium and silicon, and 7000 series is alloyed with zinc.

Non-graded aluminum cast from a foundry is often 'mystery metal' and is what you would get if you buy cheap aluminum plate.
