[s-cars] ECU circuit panel seperation and severe overboosting! Help!

[Ed Walsh]

Guys,

My S6 with newly installed 1+ software and GM 3 bar
sensor is boosting to over 28 PSI, even though it
should see 22-23 max.  Not good.  When it does this,
boost builds very quickly at low RPM (2,200)then
rockets to ~28 or so PSI by 4,000 rpm, but  without
the corresponding kick.  Clutch is not sliping.  When
it hits ~28 PSI, the overboost saftey circuitry
sharply backs off the boost until it is under control,
then it starts to build again around 5,000 rpm. The
car does accelerate, but not with the oomph you would
expect at those levels.

Is this the software or is something else on the car
not functioning/hose disconnected, etc?

Also, I have some III+ software I was going to try to
elimate the SW as the problem.  I have the box fully
apart, but I can't figure out how to release the lower
board from the black pin housing (I already
disconnected the snaps that secure the 2 boards on the
cable side of the circuit board.

What is the secret handshake?

Thank you Thank you Thank you, Ed
