Drivetrain with thick lines?

When using the Powertrain Visualization app I notice that my drivetrain lines are skinny. I dont know what this means but I think it has to do with Power of the lines.

Most cars have powertrain lines that get thicker as they pass through transfers when driving



My bus has skinny lines all the way when driving


why is that?

 

I could imagine that your bus due to being heavy and having inferior KW/kg ratios just doesnt reach "thicker" values on acceleration as the engine maintains similar output.

'When coasting the mass of the bus means less engine braking compared to the average car which also could explain thinner lines.

 

I was able to get thicker lines by tweaking these values in the engine jbeam

• "inertia":50,
• "friction":0,
• "idleRPMRoughness":20,
• "dynamicFriction":12.0

I think they were setup wrong, somehow they involve power output levels through the drivetrain, I'm sure there's other variables to tweak besides those but I haven't found which ones yet
