    What WaterBox are you running on the ski at the time?

    The TDR waterbox, when on my ski, will short out a sensor in a matter of minutes, due to water back-flowing into the exhaust manifold. I now swap back to the stock waterbox when planning to check AFRs.

    You can try this: http://www.dynotunenitrous.com/store...?idproduct=158

    That should help isolate it more from heat and water. Also listen to Cdawg's post. Waterbox and routing of cooling hoses can make a big difference.

    I am running with the same afr gauge and RIVA waterbox, with the r&d cooling exhaust restrictor plate. With no, problems with the 02 getting wet.

    With Riva waterbox I had no problems but my water routing is reversed to stock. I put the cold water all into the head first.
