      You want to know if you can use one or borrow one?
      We do use a Innovate LC1 and a 14point7 SLC

      Lots of us use it. And irrespective of somebody else using one, you should always be using one.

      I am using a zeitronix zt2 and have no problems tuning 4 strokes with carburetor.

      But I am getting very big differences when using it on 2 strokes, with normal exhaust and also with expansion Chambers.

      Any information on reasons?

      Turbulence (from the inherent nature of the two stroke engine) at low load and idle will make the values unreliable. But you should be able to get fairly decent readings for a WOT run. Make sure you have some mechanism for logging RPM (use a separate pickup?) and smoothen out the AFR values as required after you get it into a log file. Maybe share the log with us, and harrie and I can probably help.

      The oil will reduce the life of the sensor, so use only when you need it.
