My friend installed a DE ecu tothe ze engine , has millenia manifold. It runs rich. Muffler stays cleam weith the ZE ecu but runs funky and with de ecu runs faster but gets horrible milleage, we are trying to hook the air to fuel ratio auge. What 2 wires do we hook to the gauge? We know two of them are the oxygen sensor heater but which ones do we connect?

I wouldn't waste my time with narrowband sensors. Is he using the de VAF as well? otherwise he'll be running very lean. Just put the k8 ecu w/je50 vaf in and leave it alone unless he wants to get a kl31/36.

Well to answer part of our question, if your talking about the wires on the air/fuel gauge there is 3 wires (Power, Ground, Signal) If your talking about the wires on the 02 sensor its a 4 wire, and i didn't touch the wires there i tapped them off the ECU way easier. I belive center ECU clip but can't remember the pin #...do a search and i am sure u can find the pin out on ur ECU
