Scania Realistic Retarder & Engine Brake

This mod makes the Scania retarder and engine brake behave in a more realistic and progressive way. In the vanilla game, the retarder works as follows: Stage 1: 20% Retarder Stage 2: 40% Retarder Stage 3: 60% Retarder Stage 4: 80% Retarder Stage 5: 100% Retarder + 100% Engine Brake + Automatic downshifting to increase engine RPM This mod changes the braking logic to: Stage 1: 20% Retarder + 25% Engine Brake Stage 2: 40% Retarder + 50% Engine Brake Stage 3: 60% Retarder + 70% Engine Brake + Automatic downshifting to increase engine RPM Stage 4: 80% Retarder + 90% Engine Brake + Automatic downshifting to increase engine RPM Stage 5: 100% Retarder + 100% Engine Brake + Automatic downshifting to increase engine RPM Credits: Tiago Lanzarini
