    lambda sensors on a 300

    who is running a lambda on there 300 and with what success have you had?
    have you modded your waterbox?
    have you removed the exhaust filter?
    just looking for useful feedback on how you are doing it, as there is only one place to mount the sensor and the 300 seems to suffer more with water fouling.

    Got mine in that "one" spot everyone else does and im with you, cant seem to keep the sensors alive unless i wire it to a switch and leave it "on" all the time or just take the sensor out when done

    No wb mods and the filters still in there

    The Kawi's seem to have to much water in the exhaust stream. I have the same problem with the turbo ultra.

    That will be a good test.

    Its higher up near the cyliner head so it should be more dry but it could get more condensation when it cools.

    thanks mike h i new you had one and was wondering how it was lasting, looks like some sheilding is in need, never had this problem on the 250/260. well not as quick anyway at fouling.

    my theory is that exhaust filter is doing its job and trapping some condensation in the system before it goes back in the head but at the same time thats where we put our o2 sensor killing them... but it doesnt take no rocket scientist to figure that out

    I agree with that, and also the filter at low rpm could cause a low pressure directlybehind the filter and another side affect is the cylinder pulses are not as strong because the filter difuses the air flow and it drags moisture up onto the sensor..
