So, I am trying to make a power train for an older mod vehicle. My speedometer is greyed out, it does not show any rpms or the redline. I have a complete powertrain according to the app ingame. engine - clutch - gearbox - transfercase - 2 outputs to front and rear driveshafts. Here's code: { "fullsize_engine": { "information":{ "authors":"karost", "name":"Inline-6", } "slotType" : "fullsize_engine", "slots": [ ["type", "default", "description"] ["fullsize_exhaust","fullsize_exhaust", " Exhaust"], ["fullsize_transmission","fullsize_transmission_A", " Transmission"], ["sky_turbo","turbos","Turbo"] ["sky_tuning","ILS","Improved Launch"] ["R34_supercharger","R34_supercharger","Supercharger"] ["sky_transfercase","sky_transfercase","Transfercase"] ], "flexbodies": [ ["mesh", "[group]:", "nonFlexMaterials"], ["fullsize_engine", ["fullsize_engine"]], ], "powertrain": [ ["type", "name", "inputName", "inputIndex"], ["combustionEngine", "mainEngine", "dummy", 0], ], "mainEngine": { "torque":[ ["rpm", "torque"] [0, 0], [500, 195], [1000, 222], [2000, 250], [3000, 273], [4000, 323], [4400, 397], [5000, 405], [6000, 412], [7000, 418], [7800, 250], [8000, 0], ], "idleRPM":1050, "shiftDownRPM":2800, "shiftUpRPM":7000, "maxRPM":8000, "inertia":0.2, "friction":0.01, "brakingCoefRPS":0.05, "burnEfficiency":0.05, "dynamicFriction":0.025, "torqueReactionNodes:":["e1l","e2l","e4r"], "particulates":1, "throttleSensitivity":0.2, //cooling and oil system "thermalsEnabled":true, "engineBlockMaterial":"iron", "oilVolume":6, //engine durability "cylinderWallTemperatureDamageThreshold":150, "headGasketDamageThreshold":1500000, "pistonRingDamageThreshold":1500000, "connectingRodDamageThreshold":1500000, //node beam interface "engineBlock": {"[engineGroup]:":["engine_block"]}, "breakTriggerBeam":"engine", }, "vehicleController": { "clutchLaunchStartRPM":1600, "clutchLaunchTargetRPM":2200, //**highShiftDown can be overwritten by automatic transmissions** "highShiftDownRPM":[0,0,0,2600,2850,3050,3150,3150] //**highShiftUp can be overwritten by intake modifications** "highShiftUpRPM":5300 }, "nodes": [ ["id", "posX", "posY", "posZ"], //4.5L V8 Engine {"frictionCoef":0.7}, {"nodeMaterial":"|NM_METAL"}, {"selfCollision":false}, {"collision":true} {"group":"fullsize_engine"}, {"nodeWeight":24}, {"engineGroup":"engine_block"} ["e1r", -0.13, -1.15, 0.32], ["e1l", 0.13, -1.15, 0.32], ["e2r", -0.13, -1.69, 0.32], ["e2l", 0.13, -1.69, 0.32], {"engineGroup":"engine_intake"} ["e3r", -0.32, -1.15, 0.70], ["e3l", 0.32, -1.15, 0.70], ["e4r", -0.32, -1.69, 0.70,{"isExhaust":true}], ["e4l", 0.32, -1.69, 0.70], {"engineGroup":""} {"group":""}, ], "beams": [ ["id1:", "id2:"], {"beamType":"|NORMAL", "beamLongBound":1.0, "beamShortBound":1.0}, {"beamSpring":14001000,"beamDamp":250}, {"beamDeform":2200000,"beamStrength":"FLT_MAX"}, //engine ["e1r","e1l"], ["e2r","e2l"], ["e3r","e3l"], ["e4r","e4l"], ["e4r","e1r"{"isExhaust":true}], ["e1r","e2r"], ["e1l","e2l"], ["e3r","e4r"], ["e3l","e4l"], ["e1r","e3r"], ["e1l","e3l"], ["e2r","e4r"], ["e2l","e4l"], ["e2r","e3r"], ["e2l","e3l"], ["e2r","e3l"], ["e2l","e3r"], ["e1r","e4r"], ["e1l","e4l"], ["e1r","e4l"], ["e1l","e4r"], ["e1r","e2l"], ["e1l","e2r"], ["e3r","e4l"], ["e3l","e4r"], ["e1r","e3l"], ["e1l","e3r"], ["e2r","e4l"], ["e2l","e4r"], {"beamPrecompression":1, "beamType":"|NORMAL", "beamLongBound":1.0, "beamShortBound":1.0}, ], "triangles": [ ["id1:","id2:","id3:"], ], } --- Post updated --- I solved it myself, sorry for wasting your time. I had to put a vehicle controller in my main .jbeam
