Follow these steps to tune your tyre pressures:
−
* good values are dry 28,0 - 28,5 psi and wet / cold ~30 psi
+
* Drive 10 laps and watch the tire pressures at the end of the longest straight, usually at the start/finish line.
 +
* The optimum GT3 tyre pressure is between 27.3 and 27.9 PSI (with DHE Compound - 2020 tracks). For GT4 cars, tyre pressures between 26.8 and 27.4 PSI are optimal. For wet tyres, pressures between 30.0 and 31.0 PSI are optimal. Going under this will result in underinflation and a loss of grip, going over this will result in overinflation and a loss of grip.
 
* The default settings usually give you lower values. Increase the values in the tire setup menu to compensate for this difference.

* drive a few more rounds and watch the psi values.
+
* To adjust for changing track temperatures, remember the following ratio: .1 psi for every 2C change. When the temperature increases, decrease the pressure, and vice versa.

! Value !! Description

|-
 +
| 1 || Very aggressive friction coefficient, max braking performance, aggressive disc and pad wear. Pedal modulation can be tricky if out of temperature or as it wears down. Use in hotlap and qualifying sessions, sprint races and can withstand 3 hours races. Risky and dangerous to use over 3 or 4 hours because the pads will wear down, overheat and lose linearity in brake pedal feel.
 +
|-
 +
| 2 || Very good friction coefficient, very good braking performance, good disc and pad wear. Pedal modulation almost always good and linear, good feedback while overheating and gradual wear. Perfect for endurance racing, but can also be used in hotlap sessions, qualifying sessions, as well as sprint races, as what it loses in performance it regains in braking modulation and predictability. It is the default choice for long endurance races, easily makes 12 hours and can make 24 hours race too with a bit of care. It will overheat and lose linearity in brake pedal feel when worn out, but in a more predictable way and after much longer stints. Because of the lower friction, you could possibly use smaller brake ducts.
 +
|-
 +
| 3 || Moderate friction coefficient, braking zones can be longer in dry, very moderate disc and pad wear. Excellent pedal modulation also in cold ambient conditions, very linear pedal feedback. Excellent choice for wet conditions and very long endurance races. Very predictable and easy to modulate brake pad. Because of the lower friction, you should use smaller brake ducts.
 +
|-
 +
| 4 || Extremely aggressive friction coefficient. Max braking performance, extremely aggressive disc and pad wear, bad cold performance. This is a sprint race pad that can last about an hour but will show worse pedal feel, worse performance and overheating towards the end of the one hour stint. Those kinds of pads are not used in endurance racing, but included for demonstration purposes.

== Race Start Procedure ==
 +
 +
In ACC, a server administrator can specify three different methods for starting on a server (→ [[Server_Configuration#settings.json|Server Configuration/settings.json]]) and whether a short or a complete Formation-Lap should take place.
 +
 +
=== Controlled Start with Position Widget ===
 +
 +
Each driver is guided through the start of the race by a widget. The driver must always try to stay in the green area. First is the single file at 90 km/h (if doing a full formation lap), then the double file at 60 km/h.

 +
|}
 +
 +
* You can press "Drive" 30 seconds before the end of the countdown. Don't forget to fill up on fuel, or change to your race setup.
 +
* You can now start your vehicle, but not change the gear or move.
 +
* Once the timer hits 0, a "Rolling Start Procedure" warning is given.
 +
* The pole-sitter starts first and all other vehicles are now unlocked one after the other and drivers can then engage 1st gear and drive off. Note: Collisions not are possible, cars can drive through each other.
 +
* A widget is now displayed for every driver and you are asked to ...
 +
** Drive in double file if not doing a full formation lap.
 +
** Start in single file, then slow down and change to double file, usually before the last corner.
 +
* By always being on the green colored scale of the widget, you are always in the right starting position.
 +
* Shortly before the start, the widget will switch to a speed monitoring mode. Try to keep the speed in the green.
 +
* Soon after the leader crosses the start-finish line, five flashing green lights will appear, and the race starts!
 +
* Drive-through penalties are awarded for driving too fast and not adhering to the starting position.
 +
 +
=== Old Mode ===

 +
* You can press "Drive" 30 seconds before the end of the countdown. Don't forget to fill up on fuel, or change to your race setup.

 +
* Once the timer hits 0, everyone can drive off. Note: collisions are possible, so don't try to drive through other cars.
 +
* The vehicle's speeds are locked at around 90km/h
 +
* There is no positional control, cars are free to be in whatever position possible. As such, no penalties are awarded automatically.
 +
 +
=== Free Mode ===
 +
 +
At the start of the race, only the traffic lights are shown. This is usually only used by leagues that have their own race control.

Car Setup

Choose Preset Setup

You have a choice of preset setups you can load, or you can resume editing the currently loaded setup. (When loading into a session, the currently loaded setup is the Safe preset.)

  1. Safe Preset Setup
  2. Aggressive Preset Setup
  3. Wet Preset Setup
  4. Current Setup

Tyres

Tire Pressures

Current Setup / TAB Tires

The current psi values ​​are displayed in the tire app. Inflation is represented by the different heights of the middle bars. The color of the three bars represent the differences in temperature of the three tire zones. At the front wheels, the surface temperature is indicated at the top, at the rear wheels, it is indicated at the bottom.

Follow these steps to tune your tyre pressures:

  • Drive 10 laps and watch the tire pressures at the end of the longest straight, usually at the start/finish line.
  • The optimum GT3 tyre pressure is between 27.3 and 27.9 PSI (with DHE Compound - 2020 tracks). For GT4 cars, tyre pressures between 26.8 and 27.4 PSI are optimal. For wet tyres, pressures between 30.0 and 31.0 PSI are optimal. Going under this will result in underinflation and a loss of grip, going over this will result in overinflation and a loss of grip.
  • The default settings usually give you lower values. Increase the values in the tire setup menu to compensate for this difference.
  • To adjust for changing track temperatures, remember the following ratio: .1 psi for every 2C change. When the temperature increases, decrease the pressure, and vice versa.

Note: On 2018-2019 tracks the optimum tire pressure is 27.0-28.0 PSI (Compound is DHD2, this compound -compared to DHE- has better grip outside optimum but less grip in the optimum range).

Tire Temperatures

On the tire HUD display, the three temperature zones (OMI or IMO) are visualized by three bars. Their color areas change depending on the temperature: Turquoise - Blue - Light Green - Green - Orange - Red. The numerical temperature values can be seen either in the cockpit (depending on the vehicle type) or in the setup menu.

Property Values Description
Wear 3.00 to 1.50 Degree of general tyre wear (O M I / I M O). 3.00 is new, 1.5 is worn out.
Grain None to Heavy Graining is a specific pattern of tyre wear that occurs when the tyre withstands large amounts of scrubbing or sliding, usually from understeering.
Blister None to Heavy Blistering is when the layers of rubber that make up the tyre start to separate from each other. Usually caused by having very high heat levels.
Flat Spot None to Heavy Flatspotting occurs when the tyre locks up under braking and a specific section of the tyre receives much more wear than the rest. This causes an unpleasant juddering in the wheel, as well as puncturing in extreme circumstances.
pad wear The amount that the brake pads have worn.
disc wear The amount that the brake discs have worn.

Brake pads

Value Description
1 Very aggressive friction coefficient, max braking performance, aggressive disc and pad wear. Pedal modulation can be tricky if out of temperature or as it wears down. Use in hotlap and qualifying sessions, sprint races and can withstand 3 hours races. Risky and dangerous to use over 3 or 4 hours because the pads will wear down, overheat and lose linearity in brake pedal feel.
2 Very good friction coefficient, very good braking performance, good disc and pad wear. Pedal modulation almost always good and linear, good feedback while overheating and gradual wear. Perfect for endurance racing, but can also be used in hotlap sessions, qualifying sessions, as well as sprint races, as what it loses in performance it regains in braking modulation and predictability. It is the default choice for long endurance races, easily makes 12 hours and can make 24 hours race too with a bit of care. It will overheat and lose linearity in brake pedal feel when worn out, but in a more predictable way and after much longer stints. Because of the lower friction, you could possibly use smaller brake ducts.
3 Moderate friction coefficient, braking zones can be longer in dry, very moderate disc and pad wear. Excellent pedal modulation also in cold ambient conditions, very linear pedal feedback. Excellent choice for wet conditions and very long endurance races. Very predictable and easy to modulate brake pad. Because of the lower friction, you should use smaller brake ducts.
4 Extremely aggressive friction coefficient. Max braking performance, extremely aggressive disc and pad wear, bad cold performance. This is a sprint race pad that can last about an hour but will show worse pedal feel, worse performance and overheating towards the end of the one hour stint. Those kinds of pads are not used in endurance racing, but included for demonstration purposes.

Race Start Procedure

In ACC, a server administrator can specify three different methods for starting on a server (→ Server Configuration/settings.json) and whether a short or a complete Formation-Lap should take place.

Controlled Start with Position Widget

Each driver is guided through the start of the race by a widget. The driver must always try to stay in the green area. First is the single file at 90 km/h (if doing a full formation lap), then the double file at 60 km/h.

  • You can press "Drive" 30 seconds before the end of the countdown. Don't forget to fill up on fuel, or change to your race setup.
  • You can now start your vehicle, but not change the gear or move.
  • Once the timer hits 0, a "Rolling Start Procedure" warning is given.
  • The pole-sitter starts first and all other vehicles are now unlocked one after the other and drivers can then engage 1st gear and drive off. Note: Collisions not are possible, cars can drive through each other.
  • A widget is now displayed for every driver and you are asked to ...
    • Drive in double file if not doing a full formation lap.
    • Start in single file, then slow down and change to double file, usually before the last corner.
  • By always being on the green colored scale of the widget, you are always in the right starting position.
  • Shortly before the start, the widget will switch to a speed monitoring mode. Try to keep the speed in the green.
  • Soon after the leader crosses the start-finish line, five flashing green lights will appear, and the race starts!
  • Drive-through penalties are awarded for driving too fast and not adhering to the starting position.

Old Mode

  • You can press "Drive" 30 seconds before the end of the countdown. Don't forget to fill up on fuel, or change to your race setup.
  • You can now start your vehicle, but not change the gear or move.
  • Once the timer hits 0, everyone can drive off. Note: collisions are possible, so don't try to drive through other cars.
  • The vehicle's speeds are locked at around 90km/h
  • There is no positional control, cars are free to be in whatever position possible. As such, no penalties are awarded automatically.

Free Mode

At the start of the race, only the traffic lights are shown. This is usually only used by leagues that have their own race control.

Pitstop

A pit stop to refuel missing gas or repair damage is possible in practice, qualifying and racing. A driver can set his pit stop strategy in the vehicle setup (Fuel and Strategy) and change it while driving in the multifunction display (MFD). In a race without a compulsory pit stop, the pit lane is opened when the leader of the race has finished the first lap. In the middle of the lower part of the screen, the message of the race control is displayed: RCTL Pitlane is open

Server Configuration, see here: →eventRules.json

Mandatory Pitstop

  • Variant 1: mandatory Pitstop possible throughout the race.
  • Variant 2: mandatory Pitstop Window is limited in time. (Pitstop for damage repair always possible)
  • Example: Race: 18 min / Window: 6min = from 6. Minute to 12. Minute
    Acc-wiki rctl mpitstop open.jpg
  • What can be required for a mandatory pit stop?
    • refueling
    • change wheels
    • driver swap

Server Configuration, see here: →eventRules.json

Driver Swap

(in MP: Swapping the riders works, but the operation is not intuitive and faulty! Last time tested: 17.11.2019 ACCv1.1.2)

Pit / Driver Swap

Several drivers (in Blancpain real: 2-4) can form a team. All drivers can be on the server. The waiting drivers are not considered spectators in the sense of →Spectator Mode.

Using the Pit strategy page in the ( M )ulti(F )unctional( D )isplay (key: insert), the driver can assign a driver swap which will be automatically executed during the next pitstop.

In a training or qualification session, drivers of a team can use the chat command to swap drivers while the car is in the pit lane. Simply use the chat command and enter the space in the team widget. For example in "& swap 1" the driver changes to the driver who comes first. The waiting driver must be on the server.

Server Configuration, see here: →eventRules.json and →entylist.json
