I have a new Montaer MC-01 with a Rotax 915is.  The Lane B alarm intermitently lights up (does not flash) during taxi and sometimes on climb out.  Most of the time I can recycle the switch and it goes off for the rest of the flight.  I have dual Garmin G3X's with full engine monitorimg and I'm not seeing any issues there except that the MP creeps from the top of the Green Arc into a bit of the Yellow Arc and I then reduce power.

Any idea what the issue might be and is it a cause for concern? Does lane B normally alarm in the yellow? Since I don't have a Rotax dongle is there another way to troubleshoot?

    Since you have G3X, when the lane light is on, go to the Engine page > Menu > FADEC Info and it should give you a diagnosis of what's triggering the lane light.

    I had this same issue on a 912iS engine. EVENTUALLY after trying numerous things I removed the connectors off the ECU and applied a bit of dielectric grease over the connectors and pushed them back on firmly as I locked them down. Problem solved. What was irritating the lane error kept pointing at an injector.

    Thanks all for the earlier comments. 

    Here is more data.  I pulled a log from my Garmin G3X.  Now I am really confused.  Hard to see what is causing the Alarm.  I have attached the log from a flight in March and note the I get an ECU flag (Scroll to the last column and then scroll down) note the comment that says SET BARO. 

    Then when I reset the errors go away.  Since I fly out of a Class C airport (KFAY) I set the altimeter before I taxi.  Not sure what the issue is.  The log is and Excel file. Since I am still learning both the ROTAX and the G3X I may be doing something ham fisted and not knowing it.
