limiters

im beginning to familiarize myself with the limiters. Im currently looking at the maximum engine output limiter. it has the 5 engine states on the rows and rpms on the columns. Im under the impression the 5 engine states are.

0- transition
1- low density
2- low/med density
3- med/high density
4- high density

is this correct?

Basically looking at this map for example lets say 2000 rpm@ state 4 the maximum commanded fuel rate my engine will receive will be 125mm3, assuming their isn't another lower limiter.

Reverse your 1-4 and you got it.

0 - transient
1 - high air density
2 - med/high air density
3 - med/low air density
4 - low air density

I was looking at my log and noticed I had a limiter pulling back some of my timing. And all it said was combustion manager. Any idea what direction I should look ?

Post your log and tune.
