K back up a bit here.

Your using the rom editor and your logging the the a/f ratio and percent it is off from the target right?

Hondalogger has nothing to do with this, I hardly ever use that thing.

If you unplug the O2 sensor were it goes to the wideband this should keep it at 14.7 and also most widebands calibrate that way.

To go into setting go file, settings, then lambda. The lambda or air fuel is how you tell the ecu and rom editor what input you will be using, and the edit conversion ...

The best way to make sure the wideband matches the datalog is turn the key "on" have your wideband on but have the o2 for it unplugged. SO it will sit at 14.7 then connect to the ecu for datalogging and adjust the settings till the #'s match on the wideband and the datalogging. You must make sure if ...

I have had this same problem many times also:

89 civic obd-1 conversion s200b in p28

What could it be with so many with the same problem?

ok what is the loop setting on: closed or open?

What input the the O2 is the ecu seeing? wideband or normal?

What motor and what basemap and what size injectors?
