Fuel/refuel management
Here you’ll learn how to configure a circuit to manage fuel/refuel and pit stop hardware, and how to use refueling options during a heat.
Configure hardware
1) Select in the “Hardware/Circuit Setting” screen the type of pit stop you use:

Select the pit stop type “Detect a slot car inside the pit” when the slot car stays on a sensor during refueling. Only one pulse is sent to the hardware I/O in this case. That’s the exemple in the picture above: one pulse is managed in this setting.

Select the pit stop type “Detect pit and pit out” when the pit stop generates one pulse on an input and another one when leaving the piton the same I/O input.

One lap is added to a driver when its slot car left the pit stop when the check box “Add lap after pit stop” is checked.
Managing one pulse or two depends of the sensor hardware. There is one option per circuit, so all pits have to have the same type of pit in/out behaviour.
2) Select in the “Hardware” screen the I/O pin to which the pit in/out sensors are connected. The event name is “Slotcar #1: refuel sensor” for lane #1, “Slotcar #2: refuel sensor” for lane #2 and so on… Setup one I/O pin per event. This I/O pin has to be connected to the corresponding lane pit in/out sensor.
Manage fuel/refuel during a heat
1) Enable or disable the fuel management from the Briefing screen.

2) Define the refuel speed in the slot car screen
A slot car fuel consumption is proportional the lap average duration. Thus the slot car fuel decreases each time a slot car completes a lap. The slot car average consumption is setup in the slot car screen. Define here the average laps a slot car can run with a full tank at an average speed.

Define also in the slotcar screen the average time needed to refuel (in seconds).
The slot car refueling starts:
- either by pressing a keyboard key (A for lane 1, B for lane 2, C for lane 3 and so on...)
- or by detecting pit in/out events as described previously (refuel sensor)
The "reference average speed" is the slot car average speed. This parameter is calculated by UR30 from the slot car lap statistics. The slot car consumption uses this parameter as a reference to compute fuel consumption.
The slot car consumes more when the average lap speed is above this reference than when it is below.
