Adding some extra Data .. From the last car happening.

Please check the datalog .. First 10 sec the map is stuck. We took ou the connector, plug it again.. Re-fire the engine .. And the reading back to OK.

WBO with Analog channel direct to pin ...

BC have a fuse before entering B2, other terminal have a tic-tac switch to turn boost on and off aside the VSA switch, the ground used for it is from the body.

If these are all removed, does the same issue persist?

Let me try that ...

The only strange thing is that this "lock" happens in other cars too.

Just Removed the wires ... Same Issue ... Just happens with 4bar map sensors. With OEM Map .. Nothing happens.
Attached the starting datalog wth cut wires.

What else can we test spunkster? Thanks

I tested this in our 06 Si and it reads the 4bar as it should. I suspect there is some other cause on these vehicles.
