Hello,
I have noticed when looking through the FS2004 Value Variables lists that some entries are "corrected." I tried using TURB ENG1 CORRECTED N1 instead of TURB ENG1 N1 in my test gauge and the needle doesn't move. If I return it back to TURB ENG1 N1 it is okay again. I haven't found any references that explain what is getting corrected and how, so I am now wondering if anyone else may know. I am teaching myself how to do this (with much help from reading these forums!) so it is very possible that I missed something in the SDK or elsewhere.
