R32 ECU in R34 connection issue

[Tommey]

ECU is a R32 ECU bought from Nistune and also modified by Nistune.
My consult cable and drivers are OK, tested and working in my S14.
Car starts and drives but Nistune will not connect.
Using correct adressfile (R32).

The CLK wire is checked and tripple checked.

Any ideas?

I can connect to the stock ECU without problems.
It will not work with the R32 ECU.

R34 GTR ECU works okay in vehicle, so factory consult port works fine
CLK line appears to be wired to correct pin locations on consult port and ECU plug
Customer verified connectivity from CLK line pin at ECU to pin at consult port
