Two questions for you.
1. Did your guys ever figure out the standby power consumper if the unit is left plugged into the OBDII interface?
2. Why do all OBDII responses seem to start with '4'? Does this ever vary?
Say I issued an 0101 and the result is 41 01 81 07 65 04. I get the 1 01 is the pid request, but why is the first digit 4?
