engine parameter control

Hi everyone,

Thanks for all of you who have helped me in my previous problems. Some of them had been solved. You can post your queries regarding those problems that I posted previously.

However, I still have other problems which need your help again. Is anyone aware of the logics that control the n1, n2, egt, and epr value on the GC? By changing those logics can increase or decrease the indication of these parameters on GC. (fs1n1 controls the n1 value? and what are their max and min values?)

What is BlL, BlR, BlM, and BlA?

Thank you
