OXYGEN SENSOR HELP NEEDED

lf-tp2511Member

In a nut shell, are all three wire narrow-band oxygen sensors basically the same from an electrical signal basis?

I have a Halmeter AF/30 air-fuel meter on 2511. It is using the supplied Bosch 3-wire narrow band sensor. Common ground for heater and Lambda signal.

I also have, in a box, a first-generation ANALOG Holley Projection 4 TBI fuel injection unit. Came with 2511 and I'm moving towards installing it next winter.

This can be upgraded with a 3-wire, Holley narrow-band-based O2 kit to provide better closed-loop AF monitoring in low/mid ranges.

There is one of these upgrade kits on eBay, but it is minus the O2 sensor.

Should the Halmeter 3-wire sensor work for the Holley kit?
