is an AEM 30-4100 linear or non linear?

[Whizbang]

trying to get it setup in my megasquirt and it has an AEM linear WB and AEM non linear Wideband. Not sure what the type i have is. I bought typical 30-4100 UEGO gauge kit thing. Worse case ill do the "generic wideband" and enter in the values.

Check the AEM manual.

Linear. 0v = 10:1, 5v = 20:1.

Check the AEM manual.

Linear. 0v = 10:1, 5v = 20:1.
I'm 90% positive it's linear. The instructions say what voltage corresponds to what air/fuel ratio. I remember having to set this on my old Protege. IIRC, the instructions are also online.
