First test drive today after correcting the N75. Boost not anymore going through the roof.
But I have what I call 'boost pumping': boost swings between 10-15 psi at mid range rpm.

bad video here.

I will attach VAGcom log later.

I set the fuel pressure to 43 psi (3.0 bar as per Giac).
I ran a 5th gear log WOT for the mid RPM range where the boost pumping occurs (slow enough to get at least some data points with VAGcom).

Attached is the excel file. I don't see anything weird there. Can someone take a look and see if there is anything that points to the culprit for the boost swings?

1) please do not upload excel files. Stick with the plain csv.
2) consider using ecuxplot

Thought its for Me7.
Works on AEB ecu for data logging? If so, will certainly try.

NYET: can you send me the ecux definition file for 1998 AEB ECU 8D0 907 557 P?

Reason?

I have log parsers that parse .csv

When people post excel files, they save it off in various unparseable (and proprietary) excel formats. Even exporting it back to .cvs generally ends up with something not even close to what the original was.
