Sounds like a clutch linearity issue. RF2 does not allow the mod dev to have a 'biting point', or for the car to have anything but a linear clutch - that's a problem when you're pulling out the pits with less than 100bhp at low revs and you have a clutch that's good for 1300bhp. In this case, the clutch is going to be fully engaged in the first 1/13th of the movement. That's going to cause a lot of people to stall. Obviously, the solution is more revs, and less clutch.
I have slightly increased the engine inertia for the 0.45 (in-progress) version and that will help a bit. It should be a bit of a faff to pull away though, as you can see in this video:
There is a much neater solution, and I think more realistic (clutches are not linear in real life); RF2 allows you to make your clutch controller input non-linear. I suggest going for the max 200% - as this non-linearity is closer to real life, though still far from perfect. In fact I'd suggest everyone do this, regardless of what content they use - I can see no reason not to. The drivetrain simulation in rf2 is quite limited.
I am going to be working on some small turbo amendments in the near future, and this will be towards helping the bmw engines spool up at low revs when under a consistent (low) open throttle input, whilst keeping everything else practically the same. Tricky to get right. But I'm very happy with how the turbo performs in every other aspect and this is tuned very accurately to real performance. I don't want to undo the good work here so I will have to be very considerate.
The 3-5 4-6 shifting is off the table at the moment as linear selection is forced when shift protection in used. You will find the cars where you can still freely change between all gears do not use the 'must use clutch' feature. It's a trade off I'm willing to make for the moment. I think s397 will update this as the Caterham is also affected, much to it's determent.
The sound will be improved. I still have an awful lot of physics to do so I'm staying focussed on that mostly, and not putting too much time into sound as it can be a huge time sink - sometimes for little or no gain. That will come though - it deserves a proper Tag soundtrack.
). Such a great flowing track with endless drifting, can be tricky to overtake but there are possibilities. Wish it still existed, far better than Interlagos IMIO.
