    I had something similar going on with my ski
    And struggling to find a cause
    Pretty sure I have now found the issue
    Only because it got worse
    I found the vacuum hose to the map sensor had a small split
    Because it was up under the sensor
    It was not something you see easy
    Ski was rich at idle
    And started to get lean after 7,000 revs

    The ski may very well be fine. It’s just the sensor that’s bad.but the fact that it’s showing readings so erratic is concerning. Sensor should be here today so we’ll see what happens.

    Being That the AFR is so difficult to read is there anyway to have a system set up to allow better reading or perhaps data logging? My friend has a map to know that he could lend me but do I need a license to do the data logging or just the harness?

    The Maptuner licenses are tied to the ECU so you'll need a license for your ski

    Depending on your conditions, the O2 sensor can go bad fast in two seasons. If you keep it in all the time, watch out. I find when they read high at idle they are done.

    Always keep a spare and you can swap and compare readings.

    Maptuner and data logger worth every penny.

    yea was afraid of the license part. Hopefully it’s just my sensor.

    my last ski had a riva o2 sensor adapter and I left it in all the time. Never an isssue. I am using the aqua sport now. If the sensor went bad already after just 5 hours of use, that will suck.

    when you say high at idle, do you mean lean? Like 12-13?

    Going bad after 5 hours would be water contamination most likely. I have been leaving mine in but only getting 2 years/seasons out of them. My dead senors typically read 14 to 15 AFR at idle. I have the Riva O2 block. You can get replacement sensors at Autozone. I log all my data so I compare O2 readings to see if the sensor is accurate. I made the mistake of tuning to a bad sensor. Luckily the tune went rich not lean.

    For the record and I am not saying you should do this, but you can load your tune up in a ECU with a maptuner/data logger license and get data. I have two 2016 skis and swap ECU's. You need to wire in the PLX. Not trying to rip Riva off, but if you have a friend that will let you "borrow" there setup you can get some data.

    Took out the old o2 and it was wet and full of soot. What is causing it to get so wet? Should I switch to the riva 02 kit?
