Hondata

I am a little confused.

I have an AEM wideband controller and guage that does linear analog output from 0-5v. I have been told that hondata will only read from 0-~3.8v so I can't use the full scale of my O2 sensor. Is this true? or is this old info? It seems the PLX does 0-5v so why would the AEM 0-5v be a problem? Also this is S300 in a P72 ECU

Can I just wire my white 0-5v signal wire into D14 (O2) and use my wideband as the regular 02 and not run a narrowband? Is this somehow a problem?


Also what pins can I use (if any) for +12v and Ground for the unit? I would like to splice these connections into my OBD2a-OBD1 harness converter instead of hacking any factory harness wires. This is in a 98' Prelude by the way.

Thanks

I got that thanks,

So hondata doesn't have a problem powering the WB02 off of A25? and just chassis ground the ground?

Also can you run without a narrowband at all? is that going to throw a code or can I disable the checking for the O2 sensor on D14?

Power and ground should not be from the ecu. You shoud use the fusebox as our instructions say.

You can run in open loop, but you really sh oud have it in closed loop for both economy and safety. This is why we recommend the PLX.
