Any way to disable specific FFB effect?

[Amarok_73]

Hello,

I’d like to ask if anyone knows whether it’s possible to disable the force feedback (FFB) engine-related shaking effect.
I recently switched from the G940 to the Moza AB9, and I've noticed a constant vibration during straight and level flight. This seems to be caused by direct input rather than "Telemetry FFB" settings.
Disabling the in-game shaking feature (found in the axis binding settings) does stop the vibration, but unfortunately, it also removes other effects that I’d like to keep. Is there a way to disable only the engine-related shaking while preserving the rest?

I’d check your software/telemetry settings. I have a Rhino, and don’t have excessive shaking.

There is a setting for “jet engine rumble” (I forgot the exact name) in TelemFFB but by default it’s pretty weak.

Some combinations of settings can also cause oscillations in your stick, so you should be careful with that. I have no idea how extensive Moza’s software is though, so perhaps you’re better off asking this question in Moza’s discord or on their forum if they have one

@Raven (Elysian Angel) Thanks for comment, but I've already checked all the other options and this one apparently comes from the direct input, meaning the game sends this to the joystick, not the software.
I tested this by turning off each of the telemetry parameters in the Moza Cockpit software and checking whether it affects the strength of this particular effect. Only the Direct Input option with the aforementioned shocks in the in-game axis binds enabled causes this shaking and it is proportional to the value of the vibration parameter set there. Switching to FFB telemetry in the Moza Cockpit only also causes this effect to disappear (similarly to turning off vibrations when using Direct Input), but also others, the lack of which significantly worsens the quality of the interaction the plane has with me using FFB. Therefore, the only sensible option for flying the F-4 is "Integrated FFB". It is true that you can set the proportions of mixing the effects from Direct Input with FFB Telemetry so that this effect is minimal while maintaining the other effects to a relatively satisfactory level, but the one coming as I assume from the engine, will still not disappear and will be felt all the time.

I’ll hop in the F-4 later today then to see if I can figure out exactly what you mean.

But my experience so far didn’t leave me with the impression of an adverse effect that I feel needs to be disabled.

The only time where I did have annoying vibrations and oscillations was because of too high levels of friction and inertia I had set, which interacted with damping in an ugly way. Tuning down both friction and inertia fixed that for me.

I don’t know anything about Moza software, but in the VPForce software there are so many options for tuning, it’s easy to mess something up

I prefer to fly on very low settings when it comes to the basic ones like spring, intertia, friction, damping and such.

There are a lot of parameters in the Moza Cockpit software, but they are all grouped functionally, very clearly and comprehensively described, so it is quite easy to analyze the origin of a given effect that interests us.

We could get a grip on the Discord, so I could show You how does it look on my side, and perhaps that would be beneficial for this investigation.
However, I still secretly dream that maybe one of the HB representatives who are knowledgeable about the subject will jump into this topic and simplify the whole process.

That would probably be best, as they are the ones who coded it in the first place. However, I doubt there is any significant problem with the module itself as that would mean a lot more people would have complained about it months ago already. Still, I'll check again in a bit, and hopefully someone at HB replies here too.

Btw, I also prefer to keep my settings on the low end, not just to prevent overheating of the base, but also to prevent any possibility of damage to my unit.
For reference, I use 15% damping (but it ramps up with spring force), 1.5% inertia and 1.5% friction (which is just enough to be noticeable). I use 80% master gain and 100% on both channels in the DCS F-4E Special Options. I have seen a lot of people comment who use 200-300% gain in the Special Options, but I leave it at default and make changes in the VPForce software instead.


P.S. Oh and in the software I use half force on roll and full on pitch, so for example the 15% damping I mentioned earlier is 15% in pitch and 7.5% on roll.

Ok I think I figured out what you mean: there is a slight (very slight) constant rumble that is indeed caused by engine vibrations. I actually like that effect, as it makes you feel you're flying an older - very mechanical - aircraft.
And yes, you can turn it off completely (at least owners of a Rhino can). If you can't, it's a limitation of the Moza software and something you should bring up to them.

This is what it looks like for me (default settings):

In Moza software, there's indeed separate set of parameters for jet engine rumble, but they're active when Telemetry FFB is in use.
But this vibration, that you described quite accurately is evidently related to the Direct Input mode, which gets the effects from the simulator. 
And to be honest, I wouldn't mind this effect if I'd have FFB hardware like Rhino, but Moza AB9 doesn't feel as robust as the Rhino, and it hasn’t been on the market long enough to truly gauge its durability. At the same time, it’s expensive enough that, for someone with limited means like myself, the abundance of unnecessary features raises concerns about how long I’ll actually get to enjoy the device. Yet.
