Oh how nasty to bump this thread..

The product is still in stock and the first positive review is out, soon to be followed by SimHQ, plus a few users, who I didn't pay for it, expressed their positive feelings about the kit as well:

I'll put a fiver on him not or barely even hitting the wall if he did the logical: apply opposite lock and take some power away, realise its not going to be saved, slam brakes, come to a halt somewhere on the road, not in the wall.

And of course engine braking goes through the gearing so in higher gears there is even less of it noticed at the wheels.

I have yet to see a real engine braking 'torque curve' and see how much there is. I have torque curves with also a 'losses' curve in there, the power loss when ON power, which I assume will be the engine braking minus the 'closed valve' effect.

In rFactor its quite funny, engine braking you could theoretically tweak by ear, how long it takes for the engine to rev down, but there is engine braking and inertia that do this.

I have seen a V8 engine with the inertia of a truck tire and the braking torque of a.. V8 engine.

In my mods I set engine braking to slowly increase from idle rpm to a % of the engine's peak torque applied at the peak power RPM. While subjective, most my cars use between 20% and 25% so if an engine has 300Nm at 4000rpm and 350hp at 5500, and I set engine braking at 20%, I have 20%*300Nm = 60Nm engine braking at 5500rpm..

I doubt engine braking can be severe enough to be the sole cause of lift off oversteer or rear end lockup. Inertia also plays a role when downshifting, if the engine has to catch up a few thousand rpm in a short time.

Its an interesting topic, but who has real 'engine braking dyno' data?

I haven't had real heat problems, but when I spectate online, most drivers seem to take corners one gear lower than I do, thus spend more time up in the rev range.

Have you ever got the 'oi temperature warning' symbol?

I actually don't recall but the engine lifetime equations are probably set so that it lasts 100.000 seconds at peak power rpm, 5800, but only 10 or 1 second at 8000rpm. All this being at 95 or 100c oil, hotter oil will reduce the life..

It should probably take more beating than a race engine which is run closer to its limits. Perhaps the server had damage x2 set?

I had a 10 lapper at Monza and I sometimes thought 'oooooooh risky' on the downshifts, but it lasted. It really doesn't like overrevving during downshifts. We might make it a little less weak but be nice and it should last hours..

Quote from BlueFlame :

You feel the turbo kick in at about 4500-5000rpm

as you can see from the torque curve, you can't feel that at all, but perhaps the sounds change to a more dramatic tone, its easy to be fooled in a sim without G forces acting on yo butt..

Quote from TiJay :

Niels - on the turbo thing, is the Supra modelled in a way that the turbo is at peak pressure all the time/no lag etc? As I noticed in the readme you chose not to add a massive spike in the torque at a certain RPM?

Yes, imo you can't simulate turbo just by having a 'step' in the torque curve. This is the curve, see attachment; its only a little lower in torque at low revs than the real engine is on boost, but fairly close to the real one.

Edit, that curve has 9% losses subtracted already.

After you run the supra the first time, there will be an entry in the realfeelplugin.ini file and then you enter the values you can see in the realfeel 'car upgrade' :

[Supra MKIV]
MaxForceAtSteeringRack=-4000.000000
SteeringDamper=11500.000000
FFBMixerRealFeelPercent=100.000000
SmoothingLevel=0

I can't really see that going all too wrong

Quote from ajp71 :

I can't get version 1 to work on either my normal install (that had the beta on it) or my 'clean' install used for Historic GT. It just seems to give an error message as soon as I try and load it (though I can't read it) any ideas?

It should work from a clean install. If you experience your issues, run rfactor in a window and ' ok' all the error messages. I doubt they still happen with a clean install of 1.0 but if they do, it should only happen one time, when you first select the Toyota mod 'race series'..

Technically the car is HOF:

2000+ votes, and the highest scoring car EVER! at 488/500! I didn't expect THAT!

The default settings are always the average of the setup range, thats how my tool works; I set a min and max for anything from springs to steering lock and the default will be the average

Edit, actually more often I set the default value and a + - tweak % range and the number of available setup 'clicks', so with the springs I say the frequency is 1.5hz with a 25% tweak range over 11 clicks.. If the resulting spring default is 100.000N/m then i'll be able to click from 75000 to 125000 over 11 clicks.. / off topic

I only know few who actually use 900 degrees, lots of people use less, have sensitive steering and tend to smash the pedals.

IMO when you are really carefull with the weight transfer, these cars can be neutral or even oversteery. I guess LFS teaches this driving style a little better than most rfactor mods but still, the average simmer is quite ham fisted / footed and I've seen plenty!

Quote from DaveWS :

Nope, that's not what I mean. If you enable the virtual rev counter you can actually see that it is revving to 9000rpm.

not here either.. can you double check the install? Perhaps its looking at another engine or something.. lets hope its not a bug

Quote from DaveWS :

Yup, the cars feel great for rFactor cars, good job with the physics Niels.

However, as crashgate says, the sounds are all over the place atm regarding pitch corresponding to the actual rpm's. I decided to fiddle around with the .sfx files, and made a wierd discovery. Niels, why is it that the car actually revs to 9000 rpm?? The in car rev counter displays less than what the actual rpm's are at, and therefore if I match the natural rpm's of the engine recording's to watch they should be, the car sounds like it's revving to 9000 rpm rather than 6700 rpm??

It doesn't? It revs to 6700, the sounds in the SFX go up to 10.000 rpm if you downshift from 5th to 1st instead of 3rd gear, otherwise that would be silent.

If you're talking about the 220hp non turbo I agree, thats not good, I'd rather use the turbo 'off throttle' sound for that.


The turbo does get more bass 'off throttle' but the pitch sounds matched to me.

Damping somewhat, nothing too major, 1% tire grip hear and there and the same minor adjustment to a few other areas such as engine inertia.

Hello,

for those who like road cars, we released the toyota supra for rFactor:
http://forum.racesimcentral.com/showthread.php?t=338005

in 220hp and 320hp form and my best attempts to use proper slip angles, load sensitivity, and real 3D suspension geometry, aero, torque curves, gear ratios and what not. We even found the ride frequencies and diff torque bias.

Of course with ~1.5hz suspensions its not a racer, plus at 1600kg its not a racer, but it should be a fairly believable road car experience that shouldn't kill you if you have some skill and a decent running rFactor, once the back goes out..

Cheers!
Niels

Its best to reply in the RSC thread because Siim is sending out the download links and he hasn't heard from LFS..

That is hilarious

Talk about a bump!

Have we seen Milka Duno? I'm really not into gender biased arguments about racing.. Danica seems to be doing well, belonging in what isn't the most tallent filled race series but still, not bad at all..

But this Milka?! A few weeks ago I saw she was multiple seconds behind the one but last in qualifying on I think mid ohio, some 5+ seconds from the pole. Then I looked at previous qually results and saw she probably didn't dare to show up on a few road circuits and when she did, 5 secs off the pace..

This weekend at Sears Point, 5.6 secs behind pole..

I actually think that anyone with some real talent would find it very HARD to be this far off the pace! Tristan would easily beat her :P

Quote from Bob Smith :

Is that question aimed at me or another Bob? I'm not aware of what issues you are referring to?


:jester:


Aha, now I understand your other comment. You are living in the future. Welcome to the present: http://www.vehicle-analyser.com/skidpan_results.PNG

Even the same car will lead to different results, the Corvette C6 Z06 was measured between 0.97 and 1.03, so not all skidpans are the same, and results might vary 6% going by this.. edit GM themselves claim 1.04

Still, road supers in LFS are rather good indeed.

Videos are not a good way to show something as you have to drive it, but I'm doing a few LMP1 cars for a different mod, solving what was sort of an aero bug, this works a treat. It is very drivable as you can see..

Of course you wouldn't drive like this if you plan to:
- stay alive
- keep your 'job' as a race car driver

but life over the limit is essential, the car invites you to find the limit and you can have a bit of a twitch and a slide, both on and off power, as an indication that you're just at or beyond the limit. None of that weird understeery driving just to avoid crashing.

When you look at telemetry its also quite different. You can actually calculate under and oversteer and when I see rFactor videos I pretty much always see the mathematic understeer. With my LMP1 car, depending on brake bias and coast diff, you can certainly get some oversteer easily into corners. Out of slow corners you can also keep the power on as you correct a slide, such as out of the first chicane at Monza, or the last turn at Laguna Seca etc.

Also at higher speed though, now that I fixed what was probably an error in aero, the balance is nice, even in 3rd and sometimes 4th gear things can sometimes go into mathematical oversteer, which is a bit more hairy of course but often you can keep your foot in and just apply some opposite lock..

I tend to post these exagerated videos to prove a point that rFactor isn't just 'understeer or die' if you treat its physics engine with ..umm physics
