    For those of you running widebands...

    ...how often are you going through 02 sensors? I'm on my 4th now. I think it's the water in the exhaust thats killing them. It'll last for a ride or two, then it starts reading odd (at WOT one run will be on the money, 12.0 a/f, then a second later it will be at 14.0-14.5) then all of a sudden it just stays at 19.9 no matter what.

    I know everyone has been saying to only run the 02 sensor when you are tuning, but i would much rather run it the entire time in case of something going wrong, and I will be able to see it leaning out or richening up.

    Is there any solution anyone has found for this? mounting it up differently?

    I have had the same one in for about a year now, just take it out every once in a while to calibrate in free air...

    BTW, the Innovate Motorsports XD-16 Gauge gave me fits with the A/F readings. It would jump all over the place. Tried and extended bung and that made no diff. in this case.
    Since I started using the MoTec I haven't had than issue. Also, used a LM-2 and did not have the issue.

    I'm running the Innovate LC-1 with a DynoTune gauge

    Good post Scott. I'll soon be running this same O2 setup so this info will help me.

    Where are you guys installing the bung on the 1.8?

    On a 4 tech, the life of the 02 sensor is much longer if mounted at end of the exhaust manifold then in the j pipe.

    I started running a heat sink also which seemed to help the life of the 02 sensor.

    Wink

    dyno tune offers a spacer nthat helps get the sensor back some and reduces the heat so they will last longer call them for this part link http://www.dynotunenitrous.com/store...ts/default.asp

    That heat sink gave me no benefit at least back when I as using a C3 Wheel.

    it goes into the OEM hole in the exhaust pipe.
