If you have the cable, you need to immediately download the software for free from here:

The UpRev page and FAQ area will give you all the answers you need. If you're confused, call them and explain the situation. Logging is VERY easy to do. You simply open up Cipher (it's one of the programs you download), plug the cable into your PC and car. Allow Cipher to connect to the car.
Select the option to log parameters, select the parameters (AFR Bank 1 and Bank 2, timing, engine speed, etc.), hit okay and start driving around. Hit the record or log button if you're able to reproduce the issue, and drive the car around in its gimped state. Stop the log, at which point an Excel spreadsheet file is automatically saved into your UpRev log folder. Send that to UpRev and for a minimal fee they will fix everything.
I do highly recommend that you call UpRev.
