Linking Wideband O2 sensor to A9L ECM
I have an Innovate MTX-L wideband O2 sensor That I'm trying to get linked up to my A9L ECM using Tuner Pro RT and a Moates Quarterhorse. I'm trying to use the Pin #27 voltage input method. The gauge is outputting 2.75 to 2.78 volts at 1.00 to 1.02 lambda at the old EGR voltage input circuit. I have continuity all the way to The ECM at The pin 27 location. I cannot get the Tuner Pro RT ADX file to recognize the signal. The settings on the General and Conversion tabs appears to be correct. The 8 other values on my dashboard are all active and working. Any help on getting this issue resolved?

There is no setup its all automatically done.
If its not logging then a wire was not making a connection.
