Air/Fuel Meter and O2 Sensor, Keep that car in tune! Options

[Justinp71]

Well it seems that a good way to make sure your car is using the proper amount of fuel is to add a Air/Fuel meter, especially since few of these cars have modern computers. So I am looking at what options are available.

It looks like one option is to buy a kit from pelican:

Option 2: Use an 80-83 911 o2 sensor and add an aftermarket gauge...(Which I guess is similiar). I would like to use this sensor, b/c there is a chance I may use an 81 CIS system later on.

So... does anyone have any recomendations and/or suggestions?

There is a a company called" JAW", out if Canada. They make a DIY WB 02 sensor controller that has a gauge that is the size of a penny.

You can use a Innovate WB sensor with it. The whole kit will run about $150. This will give you a WB AFR reading in a small package.

The Innovate controller is a little on the big side.

Overrun is what is refered to as the times you let your foot off the gas and are coasting to a stop or going down hill.

The RPM's will be up and the TB closed. A rich mixture will cause backfiring out the tail pipe.

ON an MS system there is a setting for this called" decel fuel cut %" . I run about 80% fuel cut on decel.

BTW, a WB 02 sensor is a valuable tool for the stock injection. even though there is not much in the way of adjustments for the stock system, there are enough to be able to adjust AFR. Just my.02.
