Hello all,
I found this discussion on UKTrainSim about the Indepandent Brake Needle: http://forums.uktrainsim.com/viewtopic. ... 24&t=90871
To resume: if you change TrainBrakeCylinderPressurePSI to LocoBrakeCylinderPressurePSI in sd40_2.bin file for example, the Bake Cylinder Needle will work on the right way.
After some more investigations, you can set the MAX INDEPENDENT CYLINDER PRESSURE to 72PSI, Changing MaxCylinderPressure, PressureForMaxForce and MaxSystemPressure to 72PSI (or whatever value you need) in SD40-2 Engine Simulation.bin file.
Friendly,
Jean-Louis
