360 Tuning

May be the tyres are slicks... :-)

Yeah, they're probably too sticky. To tweak the overall grip that the tires have, adjust the a2 and b2 tire coefficients. The a2 coefficient is lateral (side to side) grip, and the b2 coefficient is longitudinal (fore/aft) grip.

Nice, this is a good improvement.

Yeah, there is too little wheelspin when starting in first with TCS off. Need to bring down the longitudinal friction a bit. Also, the car hardly ever oversteers... seems like it should be a bit harder to drve.

The idle throttle position is too high.

The problem with braking killing the engine is because, for whatever reason, the rear brakes are locking up unexpectedly before the auto-clutch system has a chance to realize what's going on and put in the clutch. If you're using the SVN code, R1930 has an autoclutch tweak that makes it a bit better, but the car still sometimes dies. There are a few ways that I can think of to fix this:
* reduce the braking friction in the rear
* make the autoclutch put the clutch in under heavy breaking
* make the autoclutch react faster somehow
* tweak ABS to prevent wheel lockup

Thoughts about what makes the most sense?

After tuning the F1, such a slow car without downforce is odd. I am very happy, the 360 drives so good in version 05!

The next steps:

* lowering grip
* reduce the braking friction in the rear (the simple way)
* optimizing suspension: spring, bounce, rebound, camber, anti-roll
* a little oversteering

I found some comments about the modena. One interpretation of the name meant „360 degrees“, because the car spins effortless in curves. :-)

There are some problems, which i will explore:
* Suspension remains in upper position (also F1; a software problem?)
* Some hinge values have extrem and unexspected consequences (Car hangs in air etc.)

A few comments to the version in SVN now:
1. What happened to my changes to the hood camera position?
2. The tires are way too sticky (although that makes things interesting in its own way )
3. The suspension doesn't ever seem to compress properly. I've noticed this on the F1-02 also. It has to be something about the way the suspension is set up. Maybe I'll play around with it later...

1. What happened to my changes to the hood camera position?

;-) Sorry, i didn´t set it back. I use hood camera for fixed driver view - 2007-03-27.

2. The tires are way too sticky (although that makes things interesting in its own way Wink )

I am working on this.

This is a bug! I created a new topic for this, because it´s not 360 specific!

OK, let's keep the hood camera as really a hood camera. If you want a fixed driver camera, we could add an option to make the driver view not move.

Are there any other cars that do this? I was thinking it could be something related to hinge points, they cause a lot of problems and are admittedly very confusing, I remember when making the .car file for the XS it was very difficult to get them just right (they are probably still not quite right).

I understand "hinge" as instantaneous center of rotation.

There where irritating effects, changing the hinge, b.e. the front of the car "flies" in the air...
