wideband o2 sensor ivtec k24 engines

[wardas]

does anyone know if the k24 engines (mine is an ELEMENT) rely on readings from a a stock wideband O2 sensor. I thought I saw an article that indicated that the K24 now runs fuel/air ratios closed loop all the time-even at high RPMS-which points to the use of a stock wideband sensor since typically a narrowband sensor (if used) is able to give accurate readings only at relatively low RPMS. If stock uses wideband, then I wont have to buy the O2 sensor when I buy my fuel air logger.

Not sure about that one, but you will have to wire it o a reader, since the A/F sensors usually read only the voltage signal, while you ECU translates it correctly, the meter will only read the one signal.

how many wires going to the o2 sensor, is it 5 wires ?
