Wideband Install
My Tuning guy wants to tune my car in open loop only, and not use the factory O2sensor, my car is a 2000Civic SI OBD2B , and I have a brand new Hondata P28ECU with the OBD2B Connector built in, so I have to wire the wideband analog wire into factory O2 sensor wire in the wiring harness.....I am having difficulties figuring out what wire in my OBD2B harness to use as the ECU itself is an OBD1.....Any help???
The diagrams in our help file are correct as viewed from the terminal side of the plugs.

OBD1 pinouts for the inputs and outputs can be found in the link above.

Ok so according to the OBD1 ECU connector diagram from the help section link you posted, pin D14 is the O2 input, but my harness is OBD2B, so I am having a hard time figuring out what wire on my harness male plug to wire my wideband analog input into...The factory OBD2B ECU has a blank D connector, but the new Hondata p28 ECU I bought with the built in OBD2B conversion has pins in the D Connector....
Found it!!
Its was C16- primary O2 sensor wire ( White ) on my OBD2B harness

There are only 2 resistors which should be removed.

Re: AEM Wideband through D10 ELD
You could try replacing all the electrolytic capacitors on the ECU: https://www.hondata.com/accessories/capacitor-kit
