Hey nathan just did a test with minimal mods installed and throttling definitely is not functioning. Here is the code I used. I had the base RealSettings file with the intended throttle limits based on engine type and TL.

Mods involved Latest realfuel, MFI, Solverengines, ModuleRCSFX, communityresourcepack, and smokescreen/RealPlume RFStockalike configs.

Repro

1. Build an craft and attach an L type engine.

2. Launch and ignite engine. Since throttle starts at 50% at launch.

3. Engine ignites at 50% below launch engine throttle limit of 100% for L type <TL2

Let me know if I can assist in any other way. Thanks!


@PART
[*]:HAS[@MODULE[ModuleEngineConfigs]]:FINAL
{
  @MODULE[ModuleEngineConfigs]
  {
    @CONFIG,*
    {
      %throttle = 1
    }
  }
}

codepoet: Ah, I see. Checking in with sarbian now. :)

Thanks. It may well be that the fix needs to go in MJ. Either way I am happy to work on a fix myself, but I can't really do anything until you and Sarbian come to a common mind on what the various "Engine ignited" variables mean.

Let me know how I can help.

I'm also having trouble with the throttle limits. The engines that I set up for the Stockalike pack are fully throttleable even with throttle limits. Here's an example of one for Ven's Stock Revamp that should only run at full throttle, until later tech levels:

Svm420: Woo! Bugs for the bug god. I'll take a look.

codepoet: gotcha! And turns out it's the source of the delta V stats being wonky too. We'll get something figured and I'm happy to take you up on the offer...as soon as, as you say, we figure out what it needs to be to work! :)

lurkoholic: See above re: Svm420. ;)

Under which node for !minThrust = DEL Configs or ModuleEngines? I just checked my MM cache and I don't even have minthrust under the CONFIG nodes only maxthrust.

            IGNITOR_RESOURCE
            {
                name = ElectricCharge
                amount = 2.15
            }
        }

Here is the engine I am using to test minus the Realplume nodes.

Is there support for resource mining in the works at the moment? I was designing a mission utilizing this but I realized the stock resource mining isn't compatible with Rf. If not I'm willing to lend a hand however I can with my limited modding knowledge.

NathanKell & codepoet : I pushed a new fix for the torque in MJ-dev. If there is other related bugs contact me with some simple repro steps.

Edit : resultingThrust stays at 0 for RF engines, that seems strange.

Thanks Sarbian. I can confirm that with the lastest RF and the latest MJ I do not experience the attitude control problem that I originally started to look into. Also, the available torque figures seem more correct when the MerlinDVac engine stops burning. I will start playing again, and say so if I run into anything else that does not seem right.

Oh, and that reminds me, once again fell asleep before updating OP.

Changelog:

v10.6

  • New throttling behavior. Old bugs with it were fixed, and now there is a proper delay while thrust builds up, when igniting a liquid engine. It will take about two seconds for an F-1 class engine to build up to full thrust. The rate can be tweaked, set throttleResponseRate in the ModuleEnginesRF (or in a CONFIG that's applied to one). By default when the current throttle is within 0.5% of the desired throttle, the engine clamps to the desired throttle. Further, when setting 0 throttle, the engine instantly shuts off (the latter will change, later). WORD TO THE WISE: Use launch clamps, and make sure your engines are at full thrust before disengaging the clamps!
  • Fix for sometime "says stable but fails to ignite" issue. Supreme thanks for stratochief66 for figuring out where to look!
  • Increase ullage acceleration threshold. Cryo stages will no longer keep themselves at Very Stable, but it won't take much thrust to ullage them.
  • Add tanks for the other Ethanol resources.

Just curious, how will this new update mesh with RealPlume? I added the latter back when there was that bad no-plume bug, so now I have a grab bag of engines that need ullage & ignitions and engines that don't. It's quite odd.

Are you playing RO engines or RFstockalike?

Stockalike w/ stock revamp. Everything else about the system works exactly as it should, some engines are just "easier" than others.

RFstockalike has its own realplume configs are you using those?

I updated the Stock Revamp .cfg to include ignitions and require ullage since the last RFStockalike release. It's based on the development version of Stock Revamp. Let me know if any of the engines don't have effects with Real Plume. I think the small 1.25 meter engine (LV-900?) might be missing Hydrolox effects, but that might have been the stock LV-909 (or both).

I'm having the same issue, engine shows very stable status but then tell "vapor in the lines" when fires. Terrible situation with limited ignitions :)

This keeps happening to me as well. I mostly use LR87-LH2s for my second stages and there's about an 30% chance they will fail due to vapor in the feedlines, even though i've usually got 8 solids pushing the stage and all the engines have been very stable for quite some time.

Note, I mean 1/3 of my 2nd stage configurations suffer from this problem, the ones that do have a 90+% chance of failure.

Edit: Usually I can get around this by igniting my engines one at a time.
