1. Open the eng file in wordpad.
2. Click on the binoculars to open the search window and type in dynamic. This will get you down to the first line that has dynamic. In most files this should be the dynamic brake section. Delete the whole thing, you do not need it.
3. A few lines below this you will see the line that lists the brake controllers. Since we are removing dynamic's, we can delete it from this line. Remember to get the "," before it.
4. Go a little further down in the file and remove the brake_dynamic section that has the notches for it.
That's it.
