Below you will find modified eng files as an option for the engine included with the A&O Sub.
The files incorporate a change in the way the Independant brake (i.e. engine brake) applies/releases. It is now much, much faster acting. This helps it to feel much more prototypical when switching. To compliment the brake response, the MaxBrakeForce has been lowered as well.
To use:
1. Download the zip.
2. Unzip the contents.
3. Rename or otherwise back the originals.
4. Copy the corresponding engine file into the correct engine folder.
Go enjoy!
