I would not consider myself as "wise",but I have spent some time fiddling with the FFB files
Using at the beginning an Hex editor for modifying the DATA fields (blindly)
Then I used FFEDIT and managed to adjust the spring effect to my liking
The one that annoyed me the most is the Shake file that shakes the stick at the inset of a stall
Very UNFORTUNATELY in IL2 this damn effect is combined with :


1/ crash scraping the ground
2/ and also with the hits to the plane by bullets..
This comes I think from the program itself.
I am still trying to cancell or minimize those 2 effects to keep only the stall shake,but have been unsucsessfull up to now.
I have also put some bias on the shake action to give a slight push to releave the pull on the stick(just a bit)
I managed to isolate the machine gun shooting vibrations amplitude and frequency(machinegun)
and also set up a lower frequency for the cannon(autocannon)
The result shooting separately is good
but the firing of both at the same time is somewhat "wild"
I completely cancelled "punch" "bomb" and "mortar"(rename it to keep it safe if you want)
These files work fairly well tested on IL2,but have not been tested yet on IL2 CoD
If you want them to try , PM me but KEEP yours SAFE in case
