Aircraft Auto-Cannon Folder Locations
First, we must locate the folder in which the Auto-Cannon is located. It is located in two (2) places. The first one is below:

1. Navigate to C:/BF2_Directory/mods/bf2/.
2. Open Objects_Server.zip.
3. Open Weapons/Armament/PlaneMG/.

The second location is actually within the code of the Aircraft:

1. Open Objects_Server.zip.
2. Open Vehicles/Air/.

Within the second location, the Auto-Cannon is in the following Aircraft Folders:

air_f35b
air_j10
air_su30mkk
ruair_mig29
RUAIR_SU34
usair_f15
usair_f18

We will begin by modifying the Damage of the Auto-Cannon.

1. Open the PlaneMG folder.
2. Open PlaneMG.tweak.
3. CTRL + F and type "ObjectTemplate.damage".
4. Change the number (25) after damage to a number of your choice (do NOT exceed 3000).

Now, we will edit the Explosion Damage. This is where the main damage comes from.

1. Open the air_f35b folder.
2. Open air_f35b.tweak with Notepad.
3. CTRL + F and type "ObjectTemplate.detonation.explosionDamage 100".
