Trivial observation about cars and ECMs

     It must be interesting to track the failures of  returned dead players.
     I would agree the "New"  GM replacement # are much improved,
     especially in the area of the PCB retention in the cases to prevent
     the board from heat cycle bending and shorting.
     Usually when we see an E-PCM with a paint job and poor driveability
     a scan confirms a trip to the trash pile.
