Current Setup / TAB Tires

The current psi values ​​are displayed in the tire app. Zursätzlich is represented by the different heights, at the three large bars, the differences in the three tire zones. At the front wheels above and at the rear wheels below.

• Drive 10 laps and watch the tire pressure. At the end of the curve and at the end of the longest straight.
• good values are dry 28,0 - 28,5 psi and wet / cold ~30 psi
• 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.

Tire Temperatures

In the tire app, 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 temperature values can be seen either in the cockpit (depending on the vehicle type) or in the setup menu

Property	Values	Description

psi hot	27.3	highest recorded pressure
wear	2.95 2.94 2.94	Degree of wear (O M I / I M O)
Tires		Adjustments for your wheels / suspension
psi	25.2 psi	Pressure when tire is not stressed
toe	0.2°	the position of the wheel to the direction of travel
camber	-4.1°	the position of the wheel to the roadway / https://en.wikipedia.org/wiki/Camber_angle
caster	-10.6°	Only on the front wheels! https://en.wikipedia.org/wiki/Caster_angle

Dampers

Current Setup / TAB Dampers

Property	Values	Description
Rear/Front - Left/Right
bump		stops the springs oscillation inward. A higher number wil dampen the compression at a slow rate more.
fast bump		A higher number wil dampen the compression at a high rate more.
rebound		stops the springs oscillation outward. A higher number wil dampen the decompression at a slow rate more.
fast rebound		A higher number wil dampen the decompression at a high rate more.

Aero

Current Setup / TAB Aero

Property	Values	Description
Rear
rear ride height		high is more forgiving, low is faster but tight.
rearwing		a high number Increases drag,rear downforce, understeer and stability but lowers the topspeed and acceleration.
brake ducts		Has effect on how fast the discs cool down and earodynamica. low number=cooldown slow, high number= cooldown fast.
Front
front ride height		high is more forgiving, low is fast but tight.
splitter		increases oversteer, decreases understeer, lowers topspeed.
brake ducts		Has effect on how fast the discs cool down and earodynamica. low number=cooldown slow, high number= cooldown fast.
Fuel Load Test
temporary fuel	0 litre - ? litre	Simulates the weight of the contents of the tank and the impact on the aero model of the car. Depending on where the tank is located in a car, it has different effects.
Front Aero Variation
Base ride height	xx rear - xx front x.x%

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
  
• 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 Blanpain 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.

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