If you have an ECU that lacks the O2 heater circuitry such as a P05, it is easy to enable this functionality.

To convert a P05 to pretty much anything else, you need to add a transistor to enable the O2 sensor heater or you will throw a code.

Q30 needs to be added - C144 is its value.

For JDM ECUs that lack the O2 heater circuitry, such as the P08, simply add a SMT version of the 2N4401 (general purpose NPN switching transistor) to location Q15 on the underside of the PCB. The proper part number for the transistor is MMBT4401, and they are readily available through retail suppliers such as http://www.digikey.com
