yes, adding parameters to tuning-file. I added some AUTO parameters, use 
attached file to scan. Try "scan au-Sydney_North_Shore_test", hopefully 
it says something more that tuning failed. It is good indicator if there 
is even PID-filter timeouts.

I have no idea how to debug more. Without device it is rather hard to 
test many things. It will help a little if we know is tuner locked. 
Mike, is it easy to add debug writing for tuner to indicate if tuner is 
locked or not locked? I have used that method earlier with mt2060 tuner...

Good luck for Kimi and Heikki todays F1 Australian GP:)

regards
Antti
