MGL Avionics User Forum

Hello to MGL Forum,

I am new to the MGL forum with our purchase of a RV-7A with the Explorer EFIS. The EXP3.BIN firmware had not been updated for a couple of years. After the software install and airspeed indicator on the EFIS no longer works. What can I do to fix this issue? By the way, I have a steam gauge airspeed indicator for backup and it works fine.

Thanks,

Problem Solved. The pitot tubes to the Ibox were in the wrong ports. Put label on the tube to know where they should go in the future.
