I have a question regarding these new to me fax files, I've read up on the forum for many days but I can't make sense of one thing. I have a 411 pm / operating system 12212156, I've downloaded the lean cruise and transient fueling patches, I've sported the lean cruise into my config files and it did show up in the tube tool, however, when I export the transient fueling vac file, it saved it as 12212156(2) and I can't find the parameters in the tuning tool for said os. Do I need to copy both files together? Also, my computer will not open these cax files.
