I’m running a Gilomen ECU tune and I still get the O2 sensor code when I’m in the higher elevations. It doesn’t seem to affect anything. Still have full power. It usually seems to pop up if I idle very much, and usually goes away after a bit of riding.
So you never got the charcoal canister installed? Thanks
So you think the radiator lines are heating up the fuel? My coolant lines have been insulated with pipe wrap for months and it still does it. I haven't notice if ambient temperature effects it or not. We are heading back to CO in two or three or weeks and will do some more checking. Thanks
No that’s a winter project .
Thanks. I talked to Polaris today about the gas smell as well as the o2 sensor out of range. They acted like they hadn't heard of either problem. I then called a dealer in Lake City CO as someone had posted that they were having trouble with all of theirs. They said all of them had the o2 sensor issue at high altitude but they weren't having gas fume issues. They also said they had talked to Polaris many times about the o2 sensor issue. He said its an EPA related issue. They run them lean for pollution, then you get them at altitude and they really run lean. I asked them what gas they ran and he said 91 ethanol free - if that makes any difference.
So some of us have been putting charcoal canisters on vent tube. My machine is consistent . Always smells when we get to half a tank . We ride around 6,000 Elv.
I did complain. They said they "had never heard of that before"..
Mostly just want people to put in a complaint so polaris is aware of the issue so hopefully they can correct it. I do all my own repairs as well.
