I added a turbocharger to my tractor, but it causes engine rpm jumping up and down. Is there way to fix it?
This is the first thing I noticed: Code: "wastegateStart":170, "wastegateLimit":175, I see that you have the wastegate limiting to 175 psi but the turbo can only supply 77 psi at max. Code: "pressurePSI":[ //turbineRPM, pressure(PSI) [0, -1], [30000, 10], [60000, 18], [90000, 37], [150000, 51], [200000, 59], [250000, 68], [300000, 77], ], You might also want to increase your "maxExhaustPower" value to something higher, e.g; 50000 An other thing: Code: "engineDef":[ //engineRPM, efficiency, exhaustFactor [0, 0.2, 0.0], [250, 0.4, 0.55], [500, 0.5, 0.9], [800, 0.55, 0.9], [1400, 0.6, 0.9], [2000, 0.5, 0.7], [2500, 0.3, 0.5], [3000, 0.1, 0.3], ], In my opinion, exhaustFactor of 0.3 at 3000 rpm is going to kill the turbo, maybe use 0.45 ? You might want to use the "Turbo Activity Graph" to solve your problem, and also, send us a screenshot of the graph so we can help you a bit more. Here is an example of the turbo graph. Cheers!
maxExhaustPower defines the power of the exhaust coming out of the cylinders after combustion to drive the turbine side of the turbo. It has no unit for the moment, and we are working on removing it and replace it with proper combustion pressure simulation. Are you sure it is not the rev limiter doing its job? If not, PM me and let's take this situation into live support.
Actually , your turbo work nice , (this is showed on the wip updated torque curve app) : we are aware that it's difficult the check this on the actual version and we work a lot to give you back the torque curve app as soon as possible . The problem you encounter is actually on the drivetrain , the gearbox "cluchtorque" value need to be just slightly superior to the max torque , you need also to adjust the "closedtorque" value on both of differentials , they are also some broken link on the differentials reaction nodes :
Yes , this hit the redline , so the engine drop that's pretty realistic , and i've checked again your engine torque curve look nice ! I'm not a tractor expert , so what's are the goal you are looking for in therm of maximum speed / rpm ? Also they are still some errors on the train here :
