The highest I see it went was 1.01, try increasing the voltage below 13.96 by 0.02 and see if that helps with the AF with load.

Ok I’ll adjust and log again. I’m not sure if it would help but I was thinking of running direct power to pump through relay

I ran my wideband to the eld connection. I’m wondering if not having eld connection in causing the issue? Can I run ek civic with p28 hondata s300 with eld off ?

Did you rewire the fuel pump?
Did you increase the dead time below 13 volts?
If so what was the result?
ELD is one of the recommended inputs

Yes you can leave the ELD disconnected as it is not needed.

I performed an idle relearn to the ecu seems to have corrected the issue.
