Hi Guys, I prefer to drive without any assistance on, and when I fully depress brake pedal on almost any GT-car, I can't fully lock wheels, there is only partial lock - I can still steer left and right. Setting full forward brake bias and 100% brake power in setup doesn't improve the situation. In other sims like PC2 & ACC, I can fully lock wheels with about 60-80% brake pedal depression. (I have my pedals calibrated, sensitivity at 50, and HUD telemetry shows 100% brake application)
Do you by any chance use Thrustmaster pedals? If not then test some other cars than GT-cars - to see if it is a general AMS2 problem.
No, I have Fanatec ClubSport Pedals V3 in manual calibration mode. Ok, I'll test other cars later and report back.
The reason I asked about the Thrustmasters is because some of their pedals have some malfunctioning autocalibr functioning. The other cars thing is because I have seen it mentioned that even if you disable ABS in some GT cars then there is still some hidden abs acting.
How exactly did you turn off the ABS? Did you do this in the game settings, or in the setup of the cars?
How do you check if your wheels locking btw? With brake/tire temp change, tire wear or listening to sound? By only listening sounds (I’ve increased tire sounds via settings) I quite easily hear the time when they locked and start to gradually release brake, and I find it is quite easy to lock. Almost all setups I use have brake power around 80%.
I'm back, so I was using Options->Gameplay->Driving Assists Enabled = OFF to turn off ABS, and it looks like it actually don't turn it off completely, but if I set ABS level in car setup to 0, I can finally lock the wheels with around 70/30 brake bias on GT-cars. I've checked other cars also, and cars without ABS can lock the wheels, and cars with ABS can only lock the wheels, when setting ABS level in setup to 0. So Driving Assists selector in options doesn't help to turn ABS off. Note #1: I'm testing the lock, by driving a car at about 100 mph straight, when fully depress my brake pedal, and then I turn my steering wheel left or right, and with locked wheels car won't turn, it should continue to move straight ahead, regardless of steering wheel movements, cause when wheels are fully locked, tires can't generate lateral forces. Note #2: compared to other sims (I tested PC2 & ACC) it requires to depress brake pedal much harder to achieve wheel locks in similar GT3-cars even with 100% brake power. So I'd like to have an option to increase brake power more than 100%.
It just feels that in AMS2 brakes are weaker compared to PC2 & ACC in similar cars. So I'd like to have an option to tune brake power to achieve the same consistent feeling for braking.
If the brakes in AMS2 are too weak compared to reality (why compare with other sims?), we would expect braking distances to be extended proportionally. Is this true? Judging by the Onboards: AMS2 vs. Real Life -thread, I wouldn't have said so. Maybe I'm wrong. If the issue that the brakes don't lock enough (subjectively speaking), that could also be because the track state is very grippy, the tyres are fresh and the temperature is near-optimal. Have you tried in sub-optimal green track conditions?
I always have to brake earlier in AMS2 than in ACC. Spa at Les Combes is a good example, in ACC I brake when the left kerbs start and can still hit the apex, if I brake at that point in AMS2 I overshoot the apex. If I look at real life footage, ACC seems to have the correct braking point (with comparable fuel).
I'm not quite sure this is the best way to test this, as the setup of the car might be able to compensate for the understeer caused by front lock. To fairly asses if the wheels really lock, we should look at the telemetry. On the other hand, is it I clear indication of the issue, assuming you don't chance the setup between tests. It's really strange that these two methods of turning off the ABS results in different behaviour. Hopefully, this has helped you turn of the assists, so you can drive the cars as you want them.
I agree this is the case for the baseline setup, but after some setup tweaking, I've managed to improve braking quite a bit. Setting the camber slightly less aggressive, stiffening the front springs, and especially, decreasing ABS setting, can improve the braking distance. This will stabilise the car under braking, allowing for more agressive braking, shortening the braking distance.
I guess you are right and I have had the same suspicion a long time - but eventhough it has irritated me I have (relunctantly) changed my braking behaviour in AMS2. But I must also admit that I have not tested it out seriously - mainly because Im waiting for a competent professional telemetry (read MoteC ) adapted for AMS2. Because If you cannot check the brake output you have to rely on a rather subjective "feeling" of braking.
pcarsprofiler works with AMS2. Provides a crap ton of detail and is highly customisable. Suggest you give it a go- well worth your time and its free. pCARS Profiler (Telemetry & Analysis) [PC ONLY] [v1.6] (projectcarsgame.com)
I've not experienced this, in some cars I can bring the brake pressure down to 70% and still lock up if I really push it. Also, there's plenty of way to check the brake input being applied. If it is a calibration issue the telemetry view will show you only pushing partly on the brake pedal even if you are actually on full. Beside that maybe having a look at some of the telemetry tools to see what's happening with the locking. During my car setup run I watch the replays to check the wheels locking and for cars with TC and Abs I disable it to setup the car. Then add it back on afterwards. But you issues sound strange to me. Best of luck fixing it.
Thank you - and without the latest positive development in a comming "converter" app between AMS2 and the fullblown telemetry tool MoteC I would maybe have given it a thought. But my problem is that I after several years of use of this "real" MoteC i2 in iRacing, rFactor2, ACC (and GTR2) know what such a "real" analysing tool is able to do.
