aikxCar, ein erster Schritt
Schon länger habe ich den Plan ein Website anzubieten, die die leichte Erstellung und Verbesserung von .car Dateien ermöglicht.
Mögliche Leistungen:
- Erstellung neuer Dateien auf Basis bestehender Definitionen
- Berechnung der Gewichtsverteilung
- Brechnung der Downforce-Balance
- Brechnung des Gesamtgewichts (Wagen leer und fahrbereit)
- Grafische Darstellung der Hauptmaße und der Lage der Massen
- Vergleich mit den Einstellungen anderer Wagen
- ???
... Car Dateien:
- können hochgeladen werden
- werden nur mit veränderten Einstellungen überschrieben, Kommentare bleiben weitmöglichst erhalten
- erhalten einen ergänzten Header
- sind herunterladbar
- oder sind in einem Eingabefeld kopierbar
- ???
Bisher habe ich nur einen ersten kleinen Schritt zur Realisierung gemacht, der mir schon sehr hilfreich bei der Erstellung der Cosworth Einstellungen für den G-P34 war!

Tuning des neuen Tyrrell P34, zweiter Schritt
Der nächste Anlauf: Drehzahlkurve ist nun fülliger. Brauchbar zu fahren.
ToDo: Suspension, Springs,...

Tuning des neuen Tyrrell P34, erster Schritt
Der neue Tyrrell P34 basiert auf den AX2 .car Defintion. Ich habe etwas über diesen einzigartigen Wagen recherchiert und habe - fast alle - Einstellungen geändert:
Motorspezifikation, 7 to 6 Gänge, Federsteifigkeit, Druck-/Zugstufe, Gewichte, Abtrieb und angehobenes Heck.
Ein generelles Problem: Der Fahrer hat eine Gocart-ähnliche Haltung und passt nicht ins Cockpit!
To Do: Gewichts- und Abtriebsverteilung ausbalancieren!
Attention: unfinished work Achtung: unvollständige Arbeit

Überarbeiteter F1-02
Die F1-02 Simulation ist seit vdrift-2009-02-15 durch effektivere und realistischere Algorithmen deutlich zu schnell geworden. Ab etwa 160 km/h fährt der Wagen fast jede Kurve.
Der F1-02-5_2_0 hat weniger Downforce, weichere Feder-/Dämpfer-Einstellungen und eine geringere Endgeschwindigkeit. Trotzdem lassen fast die gleichen Rundenzeiten fahren.
Download des F1-02 Pakets mit geändertem .car File: F1-02-5_2_0.zip
Probleme mit 2009-06-15 Release
Insgesamt sind die Algorithmen der 2009-06-15 Release und der Vorgängerversion deutlich verbessert. Probleme habe ich aber mit dem F1-02 auf bestimmten Streckenvarianten. Der Wagen hebt unvermittelt ab, steigt in den Himmel und fällt oft überraschenderweise einen halben Kilometer weiter wieder auf die Strecke - etwas Geduld vorrausgesetzt. Selbst wenn der Wagen den Boden wieder berührt, muß er noch eine enorme Energie abbauen.
Typische Stellen sind das schnelle Gefälle hinter dem "Flugplatz" auf dem Nürburgring (Ring2007) und die "Fuchsröhre".
Bisher hatte ich den Effekt nur mit dem F1-02. Von cars.vdrift.net habe ich den Tyrrell P34 ausgetestet. Die .car-Datei basiert auf dem AX2 und ist dringend überarbeitungswürdig. Überraschenderweise erlebte ich den oben beschriebenen Effekt auch mit dem Tyrrell. Es scheint also doch ein Problem in der Software zu geben.
