Re: air fuel ratio sensor

[<62-65-mail-list-club@xxxxxxxxxxx>]

There are portable units, as Jim notes. Some you can monitor using a cell phone, so you don't need to install a gauge in 
the dash. Here is an older article that gives some overview.
https://www.hagerty.com/media/maintenance-and-tech/monitoring-the-air-fuel-mixture-with-uego-sensor/
 
"How To Properly Place and Install an O2 Sensor" is a video from Holley. 
https://www.youtube.com/watch?v=lyv0wh3fsLM&pbjreload=101

You can also read the "oxygen sensor installation" section on the Holley EFI instructions. 
https://documents.holley.com/199r11031r.pdf

There are conflicting views as to if you need 2 for a dual exhaust but Holley says no if the sensor is properly installed.

Thanks,
Gary H.
