Rotax 914 TLR4.6a report

I had need to use the TLR4.6A program on my Rotax 914.
Two problems I encountered
1. The current Rotax Heavy Maintenance Book only displays log information for the TLR4.3 program and 12 columns, it is not relevant to the 8 columns only from the 4.6 program.
Could someone give me a description of what each column represents for the log output of the TLR4.6a program (I have worked out the obvious ones - that leaves 4 to guess).
2. I had real problems in interfacing to the TCU unit. I tried 2 different USB to serial laptop cables on 2 different laptops, one running XP the other Windows 7 - neither worked. I solved it by sitting an old tower computer in the back of my plane with a plain old serial port. Would like to get a USB to serial cable that works for a laptop as it is difficult flying around the sky with a mains cable plugged in :(
Just as matter of interest this engine is brand new but I have had it for 3 1/2 years. I decided to check the carbs and found the needle positions different, one carb was slot 2 the other slot 3. So much for the factory tests. Now set to slot 3 and tested as per the ROAN rgearding 2200 rpm and choke testing. All perfect.
Cheers and thanks
