But, if I get Hondata s200, does it have something that I can reset the ecu for the o2 sensor?

Thanks,

P.S. - The motor is a ZC SOCH VTEC.
Are you sure it has to do with the O2 sensor? Code 4 is CKP sensor.

Even if it was the O2 sensor, there are way cheaper and better alternatives to Hondata to get the CEL off.
