Hi everyone! Yesterday I was playing around with setups for GT3 GEN2, specifically to try to adapt the cars' handling to my driving style (mainly the BMW M4). So I had the idea of using GPT CHAT to: - Analyze the default settings for the main parameters in other games, like LMU and ACC. - Apply similar settings, taking into account unit conversions, maintaining and converting the proportions, and especially considering not the absolute values, but the proportional range. Well, I'm posting here because, in my specific case, it worked really, really well. What I achieved after the suggested adjustments was a stable car, with less tendency to oversteer on corner exits, but still allowing good roll control in the corners. So I thought this might help more people looking for a similar solution. I managed to significantly reduce my time on the tracks I play most, because now I no longer have to fight with the car in the corners. **NOTE: For God's sake, test it before judging, okay? BMW M4 Differential Clutches: 2 Preload (Nm): 85 Engine Braking: 9 Rear Wing: 7 Front ARB: 8 Rear ARB: 11 Brake Bias: 59% front Brake Pressure: 100% Front Camber: -3.4° Rear Camber: -2.4°
I'm a simple person: I hear "AI" or "LLM" and I simply won't trust it. The power of understanding how stuff works is much greater than having a solution provided to you on a plate. With variable success too (yes, I get that it can be sometimes correct, but it can also be incorrect like pretty much anybody). And if there's a trial and error involved to get the AI to provide the right answer, you'll probably better off with following a simple setup guide to tweak settings yourself and actually understand what they really mean. And then fine tune it yourself without the "help" from the brainless computer.
Surprised it got as close as it did honestly but no need to use AI to do stuff like that when you just understand what the changes do. I run close to that and also run my preload down to 50 sometimes. I like loose cars that need subtle precise inputs and throttle control rather than barging around every corner and hoping a stiff car just stays planted. Engine braking up, clutches and preload down. These are the first steps for every car I get in.
Interesting. I never considered using an AI for setup tweaks. I'm an avid AMS2 racer but still very ignorant to setup stuff. Is that generally a good rule setting up the cars? Crank up engine braking and reduce clutches and preload to avoid that weird on throttle oversteer corner exit stuff?
I'm not a great lover of the Ams2 Gt3's.. I have found that engine breaking above 7 works well for most Gt3's.. improvement anyway.
Sorry but ChatGPT will just scramble stuff together it found online, it just can't actually create valid setups and can't even differentiate for what version of AMS2 these values might be good. People heavily misjudge AI and think there is actually "thinking" or even understanding of things involved, they just create answers out of noise based on data they gathered in the past (just ask for sources of their statements and the will share some old reddit posts and stuff like that). Unless you train your own AI model on tons of telemetry and setup data recorded from AMS2, AI can't help you. You might get lucky and feel improvement, but without knowledge what actually changed on the car you will trade one issue against the next one (tire wear, tire or brake overheat, losing acceleration power, etc). Just seeing these adjustments, some few notes: Changing Preload and Clutches is to me some old thing from like 2-3 years ago to solve sliding which imho just isn't helping anymore but will slow you down since you open up your diff and the left and right tires will now spin more independly therefore losing acceleration power. Same goes for tips online to reduce engine brake, of course you could do that but braking less efficiently is just moving your issue Changing Brake Pressure to 100% is a really bad idea since it can lengthen your brake distance when constantly running into ABS or straigth up flat spotting your tires without ABS. You shouldn't stand full on the brake for a long period anyway but give the brake an intitial bite. For most cars 95% is totally fine and for non-ABS you more likely reduce to like 90% it to be easier on the tires. The only reason to change camber is to even out your tire temperature between left, center and right part of the tire. You will never ever change camber to modify driving behaviour, even if that works in theory, but you have to go for evened out temps. And for this you have to run trainings, check the temps via telemetry and adjust camber until it's good. Same goes for tips online to change tire pressure to modify behaviour, the only reason to change tire pressure is to assure keeping a constitent green temp across the race if they are too hot or too cold. So what's left? Two key parts you have to learn: Knowing what exactly the issue of the car is you're dealing with (corner entry? corner exit? Balance under braking? Mid corner stability?) Understanding the physics of a car to know which setup part will change that. Here is a very simple guide to adjust your setups, and trust me, these are the only key parts you need to change from base setups until you're in such a high skilllevel that you need to find the last tenths of a second per lap by things like adjusting gearing. And remember, always change one thing at a time and only 1-2 clicks and then run multiple laps to test it. Front ARB changes Corner Entry Stability: Soften to reduce understeer, Stiffen to recude oversteer Rear ARB changes Corner Exit Stability: Soften to recude oversteer, stiffen to reduce oversteer Once you finding a good balance of Front and Rear ARB, keep the distance between the same. Change the overall stiffness of both for tracks with fast changing corners to be stiffer while more high speed turns benefit from a softer setup. Usally as soft as possible as long as it's stable is what you want Brake Balance changes On Brake stability for Trailbraking. Move to the front to reduce oversteer, move to the rear to reduce understeer. Be careful about locking up front or rear tires under braking when going too heavy into one direction. Rear Aero increases your overall corner stability for the cost of acceleration and max speed. You want to go as low as possible as long as you can keep the car stable. Have in mind for a full race you want a make safe aero setup to survive while for qualify/time attack you could go for more hard to drive values With these few values you got all tools to make the cars drive amazingly. And just one personal note from me: The standard setups for the GT3G2 are actually really well. If you actually have a problem driving one of those fast, you will need to work on your driving skills first instead of trying to force the car to fit how you're driving. Each GT3 of course has it's on characteristic that you need to adapt to and you will end up not liking to drive certain cars, even if you like brand or carmodel itself. The best way to tackle setups is that you want to be able to drive a car at the limit first, and then adapt the setup to gain time. A safer to drive setups doesn't mean the car actually is faster around the track, so you need to nail the base car to know if things like getting rid of corner exit oversteer slowed you down. The M4 GT3 is imho the most balanced GT3 and the easiest to drive. It's a perfect car to improve techniques like rotating the car via trailbraking or learning how to apply the right amount of throttle on exits. I really don't see the need to change the setup on it until you're at a very competitive level.
