Ended up figuring out how to fix it myself. The reason the ISG retrofit for the PA320 panel.cfg didn't work in the 319 or 321 was because those two models had an extra ECAMS window. Both links below are for the PA319 CFM and IAE, and the PA321 CFM and IAE. Reminder this is for the Special Version Francois Diore Project Airbus series found on AVSIM or Flightsim.
