i dont have enough info on how they work to give you an HONEST answer...
BUT the absolute BEST way to elminate the rear O2 sensor is to go obdI as that utilizes a HONDA ecu that is MADE to only have ONE sensor and a HONDA sensor, this inmho is the absolute BEST combo, i KNOW that works well, it also has tuning advantages over OBDII. i personaly DON'T trust the simulators, but i guess its better than nothing at all, i would just be curious as to how it "simulates it" like the oxygen reading that sensor would see at idle VS WOT is differant, so how does this device compensate for increased RPM and fuel demand? on a honda (as far as i know) the FIRST o2 sensor is the primary like more important... but im NOT %100 on that either... my suggestion is STILL OBDI or find someone with GOOD expieriance in the simulators..
