FFBUseForceLimiter - Not working when using IRFFB #7

Was testing with Porsche Cup today and while tuning my IRFFB settings, i lost control and ended up in a wall. I run a DD2, and typically run fairly high FFB, but with iRacing's Force Limiter I don't need to take my hand's off the wheel during an impact. Well.... not the case with IRFFB running. The impact ripped the wheel out of my hand and injured my thumb. I DEFINITELY was not expecting that. This should be a high priority fix, and possibly a warning added to the Read Me until it's fixed. If I had known the force would not have been reduced during impact, I would have removed my hands from the wheel, as I do in some other sims. Unfortunately, I had to find this out the hard way, and I'm now injured. I will say that this version of IRFFB is the best I've felt, so well done with that, but disabling the force limiter on impacts is dangerous, and I wouldn't feel safe using IRFFB in a racing environment until the Force Limiter is working.

I'm using the V1.0 version, as I don't use Simhub, since I mostly race in VR. Thanks again for the great work, and I hope this issues can be fixed, as I was really enjoying the extra detail I was getting through the wheel, and the ease of adjustability.

Hi Keno,

Thanks for writing this up. irFFB uses the iRacing FFB signal so the force reduction would still be there. With that said, I will look at enhancing the force reduction. Can you tell me what your Max Force setting was set to and your wheel setting level to give me a perspective on what force levels you were running at. I do think I can put an extra safety feature in the code. If you can, try to find me on the Busters Corner Discord channel so we can discuss further.

I was running my DD2 with the high torque key installed, and I usually target a maximum output of 18 nm from the base, which is 85% for the Force Feedback setting on the base. Then I typically double the max wheel torque value to use as my max force value, as a start. Then I adjust from there, typically adjusting on-base dampening, friction, and inertia. I can't be sure of the exact values I has set on when I had the incident, but if it wasn't those exact values, they would have been very close to those values. Thanks again!

How about the irFFB settings? Do you remember what that was set at?

Keno1109 commented 1 year ago

Max force in IRFFB was 36 nm, double max wheel torque. From memory, bumps around 40, oversteer around 50, and understeer around 40.

Perfect. Thanks.
