Rogerio,
I have bench tested the timer and have a good idea how it works and am looking forward to trying it out in an airplane soon.  I noticed that your version 3 had a programming option for retracts.  Did you retain this for your version 4?
Thank you,
John

Not Rogerio, but the Jeti Box uses the pins that landing gear used, and not enough memory to retain LG function, so no retract function.  That is direct information from Rogerio on one of my old emails.

Fred,
Thank you for the update.
John
