I think your ROM falls into the category identified by the caveat in the Learning Tables feature description:
viewtopic.php?t=9745The info is requested but the ECU sends back all ff's.
Code:
139772 INFO [SwingWorker-pool-2-thread-1] - Retrieving A/F Learning ranges...
139773 DEBUG [SwingWorker-pool-2-thread-1] - Mode:0 ECU Request ---> 8010F026A80005DF7C05DF7D05DF7E05DF7F05DF8005DF8105DF8205DF8305DF8405DF8505DF8605DF8710
139909 DEBUG [SwingWorker-pool-2-thread-1] - Mode:0 ECU Response <--- 80F0100DE8FFFFFFFFFFFFFFFFFFFFFFFF69
As for the Manifold Relative Pressure problem, can you log it alone? If so then you are exceeding the maximum query/response length allowed by the ECU. Typically you should only log 8 - 12 parameters with those being focused on the tuning item at hand.
