Hi Finn
Yes, I found it interesting tuning and reading the manual definitely =
helped there!!
As we idle at over 1600rpm I found that the first two tables don't come =
into play except as she first fires.
Ours only uses a couple of entries in the 3rd table before jumping into =
table 3 and table 7 doesn=E2=80=99t get used as its for >20 inches MAP =
below 5000rpm.
So 4 of the 8 tables are basically not used at all or rarely.
I=E2=80=99m having some difficulty tuning for the two different =
scenarios of initial acceleration and then descending where the mixture =
goes ultra lean.
Not sure if the variable pitch prop is partly to blame here.
