Fuel air ratio

Arch:

If you install the Westach dual needle gauge I mentioned earlier, you won't
need any switch or do any switching to monitor/read.

Take a look at this!!!!!!!! MSD makes a fuel air ratio indicator. Take a
look at what they just sent me. I just wrote them last night.
Sir,
We do offer a switch that will allow you to switch between sensors. The
part number is 8967. You'll require one of 8933 indicator, one extra 8935
sensor and one of the 8967 switches. This will allow you to switch between
two O2 sensors and take a reading from each header.

WAHOO I am like the looks of this.

I gave this previously, earlier today: www.westach.com, 800-400-7024.
Call them and ask for their catalog. Although they have a number of dual
needle gauges in their catalog, no example of the air fuel ratio meter is
shown therein.

Do you know where I might see one of these?

I installed a bunch of their gauges this summer, including the air/fuel
ratio gauge. They are the best gauges I have ever seen in an automotive
application. They work great. Not cheep though. But I guess you get what
you pay for...

Arch,
The air/fuel gauge is $50.20 for a single. You might call or email them and
ask if they have a dual gauge for this. Their catalog does not have all of
their gauges in them. You will have to get the senders with them also.

Their (Westach's) air/fuel ratio gauge uses a standard O2 sensor. Its best
to use a three wire (heated) sensor so the sensor starts working after
about a minute or so. Single wire sensors don't start working until the
heat from the engine gets high enough. If you already have closed loop fuel
injection you can tap the gauge off of the O2 sensor for the fuel
injection. Thats how I installed mine.
