Example: If B0910 is being used and the timing is 20 while chart B0929 is being used and that timing is 13, the pilot injection will turn on at 43 degrees and the main will turn on at 20 degrees. This is a basic explanation. Throwing in all the other tables w/ Baro, ETC, IAT, etc. complicates what I just explained.
