Using EFIE with 5-wire 02 sensor
 
I have a 2003 Honda Accord with HHO. I would like to install an EFIE to boost my 2 forward 02 wideband sensor voltages by about 0.2 volts to compensate for the excess oxygen. I have two 5-wire sensors that have two voltage inputs from the PCM to the sensor and one output wire back to the PCM. The other two wires are heater wires.

I am guessing that I need to boost the two input wiress. I tried boosting the single wire back to the PCM but generated an error code. Also, I am assuming that only the upstream sensors meed boosting. Any suggestions would be appreciated.
