Hey Dan,
Let me step in here.
As the MAPster is different than all other devices of its kind, we cannot make any conclusions as to the data you're requesting. It is to be considered "Experimental", but is showing great promise.
For my purposes, I am leaving the MAPster connected to battery voltage so it is on at all times. I felt that would be good enough and it's working. More than two weeks driving, still no code, and that with the new VREF set at less than 4.0 VDC.
Besides, at $50 it is worth the effort of install as we still need applications data.
One thing more, I'm having a hard time making out your abbreviated words. Would you mind editing your post for me? After all, I'm just a slow old country boy...
