I think the update broke ABS on road cars. I think Im now faster with ABS off. Its near impossible to lock up the tires. Can someone test it out and let me know what you think?
Maybe
@Dragonwhisky or
@Marcus Garvey
Edit: race cars on race tires still lock up lol.
And by faster, I talking maybe a tenth per sector, instead of much slower with ABS off. Ive never seen it this way before. And don't compare against pre update lap times as road cars that Ive tested are slower post update.
Not done but 3 drives I could use as a comparison. Wednesday night I ran off the Tokyo event for the Weekly challenge tickets. Used the first car I built for that credit farming race back in '24, '16 Camaro SS. When I built it then it was on Sport Soft tires. Between then and now it's had its PP "adjusted" at least 3 times and I had to put Sport mediums, then Sport Hards on it, to get it back under 600PP. Prior to 1.71 it would do 197MPH unassisted, if I got a decent exit out of the last turns, down the front straight on the SH's Wednesday night.
Thursday evening, while I was updating SNAIL resources for the "new" cars, I discovered it took almost a 30point PP nerf. I was all "hmm, can probably toss the SMs back on it to get it back up to just under 600PP". Not that it needed it to win the race. Ran the first race Thursday with the SH still on it. Since they lowered the fuel usage multiplier to x1, this car can now no stop that race. Used to have to stop between laps 6-8 for fuel and not bother changing the tires. It wouldn't go any faster than 195MPH down the front straight now, assisted or otherwise, and my best lap was a high 2:10. Prior to 1.71 I was nipping into the mid to high 2:09s. I also noticed quite the difference in SH degradation. Prior to 1.71 I was able to run those SHs hard the entire race. Under 1.71 I was having to tip toe through the turns, even with the tire wear gauges only showing half white/red, starting around lap 9.
Slapped the sport mediums on it, which brought the PP up from 573.xx to 599.xx and went out for another run. This run the SMs fell off enough I decided to pit at the end of lap 8 for tires and no fuel. That was a quick stop. Car now able to hit 197MsPH down that front straight again, even if it's later in the run to T1. My fast lap on these SM tires was a 2:08.568 and total finish time was 26:49.504. I know this because, when either of those times is a "best", I record it. The fast lap was 2/10ths slower than my best with the SSs and the total time was the fastest I've ever completed this race, with this car. Admittedly, most, if not all, of that time could have been gained in the pit stop.
I noticed a lot more wheel vibration and chatter after 1.71 update and it appears the run on SHs was enough to make my wheel cry a little and the first run with SMs had it shut down completely on the first lap. Rebooted everything and ran off the race without issue. My GPro is at 100% (11nm) torque at the wheel with GT7 torque value at 5. I do not change it car to car.
GT ABS implementation has always been daffy. From what I've heard, they way it simulates brake input pressure is to adjust traction coefficients. In other words, it doesn't actually change/pulse the fluid pressure hitting the calipers, it changes how sticky the tires are. Since the tire traction algorithms are some arbitrary logic and math, owing to the tire manufacturer's unwillingness to share their data, PD has done what they think best with those values. I also suspect, they built ABS this way because it was easier to "logic" traction numbers, since they're arbitrary 💩 anyway, than to "logic" player input thresholds.
It's been my impression, GT7abs.Activation={any.SteeringAngle + IHaveNoIdeaWhatTheThresholdIs.BrakeInput, launch.subroutine "adjust.TireTraction", or.Something.}
It doesn't really matter and frankly, I don't care how they do it. ABS was never intended or designed to be a help me go faster system. Its intent and design is a help me control (steer) my car in a panic braking event. If you're racing and panic braking, you're doing it wrong.
On another note, I'm not certain that I'll be on the grid tonight. I don't have an unmodified Nissan and it ain't worth the credits to remove it all so, if I do attend, it'll only be for rounds 1 & 3.
