NB Input to ECU?

Andre, in the AFR course you talk about calibrating and linking a WB sensor to the ECU. My OMEX 700 Series ECU is only configured to accept a NB sensor input. I have both a NB and a WB sensor in my exhaust, with the WB output going to the dash gauge and the NB input going to the ECU. Are there any special procedures to use when your ECU only has a NB input? Thanks.

Andre, tap... tap... tap... is this thing on?


Sorry for the delay. A narrowband sensor isn't really of much use in most instances since it's only accurate at lambda 1.00. Narrowband sensors however all output a signal that varies from 0-1.0 volts so there isn't anything special in terms of calibration required.

Thank you.
