Today, I released Version 2 of Scan9495 that includes support for the 93 LT1. I am sure there are some bugs, but I think it is ready for regular testing. You select the year(s) using a single button at the top left of the main screen. At present, there is no support for the 93 SIR (airbags) module. This version replaces the existing one and is in the same place as before.
Let me know how it works for you.
