Would need your input please!
I had to see a problem when logging with Datalogit yesterday.
I lost the reading of boost during the logruns.
The funny thing is, that the AVCR shows correct boost and the Power FC reading through Datalogit shows only numbers between -4 and -6, it always worked before and I had perfect boostdisplay all the time! ;(
I doubt there is a wiringproblem, as the AVCR display correct...
Did anybody have the same problem before?
Can the Power FC be damaged?
I did not change anything between the logruns!

I checked all pipes at the stock solenoid and pressurevalve, nothing unexpected and all fine connected, but nothing changed at the reading!
No wire came off at the ECU as well!
Itīs very bad to read the logs without boost displayed!
Please let me know any ideas, I can check!

Doesn't the AVCR use it's own map sensor?

Does the PFC read from OEM Map sensor?

Just a thought.

Iīm pretty sure the PFC reads from the stock sensor.
AVCR has itīs own boostpressurevalve (the small thing looking like a spinner).

My AVCR had its own Boost Solenoid Valve AND its own pressure (map) sensor. It could therefore be a problem with your OEM map sensor.

Problem solved, only the pipe was loose on the other side - I didnīt see it at first, because it was just not fully off!
Thanks for your input and advice!
