I already gave you a complete outline on how to accomplish everything you wanted to accomplish, including this. A couple of posts up.

WarpD: I know this is a very old post, however..... I have read this post over and over and am a little lost. I partly understand your instructions but there seems to be some voids.1. How does one set the idle N1 and N2 (or where)?2. Where does the information come from for one to make changes in TBL1506?3. Where does one find the information on the correct N1 and N2 values?I want to fix the default Learjet. I understand some of what you are saying but am new to modifying .air files but not the aircraft.cfg. The only way to learn is to inquire from someone who knows how and you appear to be that person.Thanks.Art Schwartz, Jr.

TBL1503 has N2 RPM as a function of throttle position and reciprocal air pressure for stationary operation, while TBL1504 has the same data for high-Mach operation. Use these tables to set your N2 values.Once your N2 values are correct, use TBL1502 to set N1 as a function of N2. You'll probably want to use a spreadsheet program to work out the data before copying it into your AIR file editor.

Thank you.Art Schwartz, Jr.
