OK I finally figured out the PIDs. Now when I try to connect I get the following error. Can V7.5 still be used somehow?

Yes, you must use V8 to upgrade your FlashScan V2's firmware, then you can use V7.5 Scan or Tune tools.

I am trying to create the Serial PID Base Efficiency Numerator - External WO2LAM1_LS1. The instructions do not say what to do with the file once you complete it? Just click save? I have attached the calc_PIDs.txt. Did I do something wrong here?

Add 2 blank lines to the end of your file.

Post log and tune files (before/after) here and I'll take a look.
