    Dual Channel Wideband Analog Outputs

    Does anyone know how to get dual analog outputs from an Innovate Motorsports DLG-1 wideband gauge? I have both channels of the gauge working fine. However, the two available analog outputs appear to be two different scaling setups for the same wideband channel.

    According to the manual, "analog output one (yellow wire) is 0 to 5V = 7.35 to 22.39:1 air/fuel ratio" and "analog output two (brown wire) is 0.1 to 1.1 V = 15.00 to 14.00:1 air/fuel ratio".

    What I'm looking for is two separate analog outputs, one from each channel of the wideband gauge.

    Thanks in advance!

    the .1 to 1.1 is lambda. youll have to figure out if there is a way to switch your second channel to afr or switch the 1st channel to lambda depending on what format youre trying to log

    The problem was that I was trying to use both analog outputs from the gauge. Instead, I needed to use the two yellow wires, one from the gauge and other from the module.
