Powerlogger doesnt show same reading as aem x series wideband.

I tried using the aem in line setting and it doesn't show what the gauge does. I have tried all the different wideband settings. I found one that gets close. What am I doing wrong here?

How exactly did you wire the wideband? What wires are going where?

Red 12volts
Black ground
Brown battery ground
White position 1 in the powerlogger block

I would connect the brown wire (which is analog ground), to the ground terminal on the powerlogger input board, terminal 4.
See if that corrects it.

Hi Eric I did that with the ground and it's really close now.

But wide band will show 14.7 and scanamaster g will show 15.0 it a little higher. For a few seconds it gets really close.

In the powerlogger software, you can adjust the reading slightly to match up. I would start with -0.1 offset to start with and see if that helps. See picture. Do this while connected and monitoring. Analog 1 is the wideband.

That was it.
