I was confused at first but it makes perfect sense. Thank you! So the more evenly grip is spread between wheels, the easier it is to upset the car, because the ability to affect the whole platform is higher. In addition, placement if center of gravity and whether front or rear steer determine when the car is least stable.

Your in-depth driving lessons are always outstanding! While other videos tell you things like "be early on the throttle" or "keep the car stable" you are telling how! Nevertheless, one thing I didn't get in this video: full throttle is green (= stable) for all steering angles. However, when I try to apply full throttle too early after a slow corner I often get snap oversteer. I guess I misunderstood something...?

the 2D matrix just isnt enough to picture all potential driving scenarios. when you exit a corner with a lot of steering applied and floor the throttle, you most likely first experience understeer. once you open the steering as the corner ends, you will come across some point in the steering where the fronts grip up again a bit and the rear suddenly is not able to cope with that resulting in the snappy behavior. the other thing is: no clue what other tiny errors might precede the throttle application. if the car was in an oversteery or understeery state, if you carried relatively high or low speed for the corner, where the car was pointing in relation to where it needs to by the time you hit the throttle. i tried adding a 3rd layer to the table separating everything by entry, mid and exit phase of the corner. but yeah... 3D charts are VERY readable :D

Interesting video ! I think you and many other channel followers, would find it very interesting if you conducted the same "experiment", but on other simm. As physics implementation ... or the lack of it produces bizarre car handling. For me personally, AMS2 has the most realistic / complete car physics model and implementation. Caution !!! Should you consider redoing experiment with AMS2, you might realize that allot of physics is "missing" / not implemented. ( video title simm, being the most notable ) Concluding, most of your observations are most likely only applicable to the simm you tried it on !

Thank you for putting out these videos to help us be better on-track drivers Nils. I commend you for that. I want to ask, does the games steering lock in conjunction with steering ratio have an effect on the numbers on this chart? Or is stability (brake bias, weight transfer, engine placement etc) going to be more paramount than those prior named sections? (I think I answered my own question in there somewhere 🤔
@SimracingPopometer
2 жыл бұрын
first a lower steer ratio would mean that all the steering angles in the chart would just be slightly lower for the same angle of the tire - but irrelevant I guess. the more important factor is that the steering is also faster and more direct/aggressive. this can lead to the rear being more snappy on turn in cause the front is now changing direction too quickly for the rear (you could steer slower as a result) as long as you don't reach the point where you over-step the grip limit on the fronts. there's also a chance you exceed the front's grip quicker than before and therefore get stuck in understeer right from the start. that means: it depends :D

Heyhey, cool video! Quick question: Does the TC factor in these tendencies? Like, if I'm exiting a corner, full throttle but the TC is acting, does it count as 60-80% throttle instead? Thanks!
@SimracingPopometer
2 жыл бұрын
no, the TC works like an actual TC. it will measure a few values (slip, slip angle and who knows what else) and based on that cut the ignition to whatever the TC setting chosen suggests. this varies quite a bit depending on the setting. but its not just a throttle reduction to prevent slip

maybe worth adding: the TC operates at a certain frequency, say 50hz. So the system will check if the tire is within our outside the allowed slip boundaries. if the latter the TC will cut power for a few ignitions, then check again if the car is back in the boundary or not and then cut again or not.

Its a great video Nils! I love your website and data packs, use it every day. I'm training for the track Suzuka, and can't find out, why u use 70-85% steering angle on the 1st sector, while i use 35-40. U still faster 0.3 sec. From 3 days i cant find it out and cant to it like you. The high steering angle is for stability like you say in this video?

is it the same car? do you use the same steer ratio in the setup? is your wheel set up correctly (meaning: does the wheel in the same turn exactly the same amount as the wheel in your hands?) If the answer to all those is yes: then indeed i am just turning more :)

@SimracingPopometer

I have deliberately spared out the pedal overlap, because you should just not do it. it will balance the car potentially. but its more like: "something will help" and eventually when doing everything, you hit the target. but ideally you a) never get to the point of needing to stabilize that much, because you dont destablize the car in the first place with wrong inputs. or b) there is always a _best_ way to do a thing, using both pedals and praying you find the right combination is not it. eventually using both pedals will cost you time one way or another. try to not upset the car, dont overslow, and if you still need to stabilize then make it throttle only

mh no i dont think so. RPMs are solely tied to speed. holding throttle during braking does not give you higher RPMs unless you drive faster. But if you can drive faster you shouldnt need throttle, just later or less braking. The Porsche imo is the only car that is soooooo sensitive that in rare situations it can be safer to use throttle outside of acceleration zones to stabilize the car.

Nils, you touched on the higher amount of steering input that pros will use in comparison to slower drivers. I have noticed this higher degree of steer angle (read as understeer in motec) while comparing driving technique to my own. It seems counter-productive to induce excess steering input if the car isn't turning any more by inducing more angle while also causing more wear to the tires. Obviously fast drivers do and it works for them. Curious if you happen to know if real life drivers use excess steering input or is this unique to the sim?
@SimracingPopometer
2 жыл бұрын
first lets not make the mistake and assume ACC just works exactly like real life. every game has limits of what it will simulate and there will be situations where more grip is available when it shouldnt. so whatever leads to better lap times in the game - for better or worse - becomes a legitimate way of driving a car second turning slightly more is not necessarily a problem. it can stabilize an otherwise loose car, it can heat up tires where they would otherwise not, and it can help balance tire wear when the rears are the weak point. so there is an amount of "excess" steering that has benefits, but there is also a limit to that and if you go further then it will become detrimental.

Depending on the track, I'm usually around 2-3 seconds off the pace of aliens. What I figured out long time ago, is that Aliens use much more steering input than me. I almost never have any graining, blistering or flat spots, even if I practice with full tank for 45min. You Aliens destroy tires like candy. I never steer more than 90 degrees and when I got the setup and replay for the car+track (or watch youtube hotlap videos), I just can't replicate the steering input (either I’m steering way less or I'm turning the wheel more slowly). The only exceptions are hairpins where it feels "natural" to turn the wheel way past 90 degrees, and when I have to react to oversteer or catch the car for different reason (like if someone bumps me). I tried different sitting positions in my rig, read how to properly set up the angle and distance of my hands relative to the wheel,... Anyone have any idea why I have this mental (maybe physical) block and how to overcome it? When I saw that table with steering ending at 90 degrees this popped into my head and I had to write this...
@SimracingPopometer

theres always a chance someone's - either your's or of the guy doing the hotlap - steering is setup wrong. so when you turn the wheel in your hands, the game does more or less than that. however, the best way to be sure is looking at telemetry data, and that's not to simply advertise the tool, but thats why we created the tool. give popometer a go if you havent already. 🤓
