Amuse Honda S2000 GT1

[Ryan Dungey]

Anyone here used this thing much? Won it off roulette took it out and well it has some weird driving characteristics. Particularly under breaking. Trying to determine if bug.

I was working on it for a while and got it to be a bit better. It's really fast if you can keep it under control.

It's not a bug just a really bad stock tune. Try using Praiano's suspension tune for it and then scaling up the power if you're going for 650-700pp. His suspensions are usually so well done that they will work with more power, less weight, different differential settings, etc. I've not tried his tune on the Amuse but most of the unruly cars in my garage have a full or partial setup taken from his tunes, that's how solid his suspension setups are.

First time I took it out onto the track it could barely steer. I raised it a lot and it would finally steer but has this horrible under breaking characteristic where it once to murder itself and pulls me off track.

i installed racing tiers on it and its good now

Oh, well maybe it was altered in one of the last updates. I've not driven it in a couple months so I'll have to check it out when I can get into the game.

If you haven't already found it/tried it out here's Praiano's page of tunes and he has two available for the car. I don't know how to just link the tune itself but you'll see it listed in both the 600pp section and the alphabetical list:

PRAIANO'S TUNES : SETTINGS FOR GT7 Hi, I'm Praiano. I'm a pizza chef living in Brazil. I have 24 years experience playing Gran Turismo and 15 years tuning Gran Turismo cars to improve handling, performance and the overall driving experience for drivers of all levels. For many years, I have...

Had a minute to run it both stock and with a couple different tunes and I don't see the instability while braking. The stock tune is a little wild and it likes to break traction if not using good throttle control, so I see that portion of it for sure. Maybe the braking issue would be more pronounced on a track with longer straights/higher speeds, idk.

Praino's suspension tune is pretty good though. Here's what I used for a 700pp race hard setup I'd use at Sarthe:

His suspension:
130 116
10. 1
40. 20
50. 30
3.15 2.60
3.0. 3.0
0.00 /\0.18

I then set the downforce to 250/470 and used 9/8/32 for the LSD. This brought it just below 700PP. Ran it at Brands Hatch and it was stable with a little bit of play in how loose the rear-end would get, but was also surprisingly quick. Came in 4th for my fastest laps in the 600-700PP section, and given that I use Brands as my "testing grounds" it was pretty shocking how quick it was. Granted it was on RH tires and I normally use SM/SS for cars in this PP range, but it was still really quick at 1:28:2, and that was just one lap, not the best of five or anything like that.

 

[Sunzi]

Yes. Love it.

I detuned slightly with a power restrictor and that seemed to do the trick. I think it's a bit too powerful for its setup in stock form.

 

[BangsMcCoy]

Not a good/fun drive in stock form, definitely requires suspension and tire upgrades and adjustments unless you want to remove power, but even then needs some suspension tweaks. Very fun drive once you’ve got a good setup. Reminds me a lot of the S2000 GT1 in GT2.

I raised it a lot

I lol'd at this.

If you raise a cars suspension too much, you increase body-roll, increasing how easy it is for the cars weight to get thrown off of its natural central point.

If you raise it too high and then brake hard, more of the weight is going to be thrown forward, making it a lot harder to stop as instead of all four wheels braking and sharing the load, the weight gets thrown onto the front two wheels. If you have any kind of steering input as well, the weight will be thrown more toward one front wheel than the other, which may take that wheel past it's grip threshold causing a loss of traction.

The problem persisted no matter the ride height. I had to raise suspension as in its stock form it could barely turn. I raised the suspension to 120 front and rear which isn’t a lot. I would be breaking everything would be fine I would be turning right then all of a sudden it would pull a hard left. It wasn’t losing traction either.

Could you share a screenshot of the setup? and even better a video showing the driving issues

Not home right now so can’t show setup. But here is a clip I saved last night. First corner turning right and you see sudden left hand pull then at end of straight under braking turning right then all of a sudden pulls left. Only car I’ve experienced this with.

 

[BrunusCL82]

Well, there could be this car in its Gr.3 version.

Sorry mate can't help you without seeing the inputs you are doing there, would suggest leaving the camera view instead of rotating it around, are you running a stock setup? I can try do some laps around the track in a stock form to see if I get similar results

I had this very thing happen with my first Integra DC2 build. It would behave normally then abruptly mid turn either yank opposite direction or just straighten out on it own even though I gave no input to do so on my end. I spent hours tweaking all of the settings but mostly suspension and brakes and never got it figured out. Bought a new (used) Integra and started from scratch and that one drives fine which is puzzling given how similar it ended up being to the first one I built.

The only time I've had a car do that, was under heavy braking during the rain.

It looks to me like the car is losing grip under braking, likely due to some adjustment you may have made. I'd reset the tune to default and start again. For reference, I just purchased the car (you owe me 250k by the way!) and took it for a spin without making any adjustments, with an optimal time of 1:58.503 (not pushing it hard). The car is a time-attack car, it's supposed to be under constant throttle for the aero to generate downforce, which benefits the handling. If you've managed to change something in the tune that throws the downforce and weight distribution off, the car will be a lot more prone to losing traction.

Aside from that, I had no issues with the car steering in stock form, only thing to note is being a car that is stock tuned to accelerate, the rear is quick to step out if you're heavy on the throttle, or slide out if you're heavy on the brakes.

Edit. Did a bolt-on tune and got 1:50, tweaked the tune slightly and got a 1:47.235.

As you mentioned earlier - you increased front and rear to 120. The car sits at 105 by default, which is actually quite high, but as a time-attack car with high aero, the downforce is supposed to press the car down lower than 105 when it's moving. Remember, this car is already tuned from stock, there isn't going to be too much more you can do to it without upsetting it.

I brought my body height down to 95/100, stiffened the anti-roll bars to 5 each and reduced the initial torque to 8, front toe-in to 0.10 and downforce to 310/510. That's a very basic tune that only really changes the cars stiffness as I found it got loose easy, and pushes it to grip a little better in turn-in. Other than that, for me at least, it's just throttle control and avoiding trail-braking with this car.

I couldn’t drive the car on the stock ride height it wouldn’t let me turn properly. The moment the game gave me control of the car it would instantly pull itself off the track. That’s why I had to raise it which made the issue less prominent but still happens. I can do a 1.46 with the issue happening it’s just annoying. Seems some people have the issue with some cars just being bugged for some reason.

Have you tried the car on other tracks to make sure it's not something to do with the track and/or the setup on the track?
