I was wondering what all you hondata users do to datalog the AEM WB O2 and have it accurately read while data logging. I've run into to issues where under full load the wideband display reads fine but the AFR's in the data logs just stay flat @ 11.2 and the voltage is flat too...

I have the 0-5v out (white wire) from the AEM WB gauge wired into the ELD pin per hondata's instructions and selected the wideband input to the ELD and adjusted the voltage offset so the display matches the ecu.

What am I doing wrong?? The hondata forum moves soo slow and hondata's tech line is a joke...

Grounding difference and offset will never allow you to get it exactly.

Just 'know' what it is showing on the gauge while you are driving and log that trend in Hondata. If you know its 12.0 on the gauge, but showing up as 11.1 in the Hondata log...you can still use that info intelligently.
