Problem with Powertrain - clutchRatio

Howdy.
I'm in the process of replacing the legacy drivetrain code on one of my mods in progress with the new very cool powertrain stuff.

For now I've just got a combustionEngine and a frictionClutch:

Code:

    "powertrain": [
        ["type",                "name",                    "inputName",    "inputIndex"]      
        ["combustionEngine",    "huskyEngine",            "dummy",        0]
        ["frictionClutch",        "huskyClutch",            "huskyEngine",    1]
    ]

Which i have placed in the engine jbeam where the old parameter section went:

Code:

"huskyEngine": {
        "torque":[
            ["rpm",    "torque"]
            [0, 0],
            [500, 90],
            [1000, 130],
            [2000, 190],
            [2500, 160],
            [3000, 120],
            [4000, 45],
            [4250, 35],
        ],
       
        "idleRPM":750,
        "maxRPM":4250,
        "revLimiterRPMDrop":100,
        "inertia":0.15,
        "friction":20,
        "dynamicFriction":0.0238
        "burnEfficiency":0.25 //0.34
        "torqueReactionNodes:":["eng_LFB","eng_RFB","eng_LRB"]
        //"energyStorage": "mainTank",
        //"requiredEnergyType":"diesel",
        //"breakTriggerBeam":"engine",
       
    }
   
    "huskyClutch":    {},

unfortunately this results in the game throwing a wobbly and giving me a 'Fatal vehicle exception'

I can't really make heads or tails of the console output other than the game is trying to perform arithmetic on something called 'clutchRatio' which it can't find.

I've searched and haven't been able to find anything relating to this either on the forum or on the googles.

Please see the attached image for the console output.

If you've got any suggestions I'd love to hear them, I've been reading and re-reading the wiki examples and pulling my hair out.

Thanks

Edit: For whatever reason, this error does not occur with a torque converter

 

Do you have also mainEngine? I'm bit on unknown waters here, but I think at some place I did read that there has to be one mainEngine which cannot be left out, rest of the engines can have other names I guess, but I haven't messed out with those too much, I have always had just mainEngine.

 

Tried changing the name and it actually worked! Thanks!
