user script outputs
script out x name
Defines a custom name for the user script output to easily identify its function.
User script output (io.set / io.pwm) example - activate a cooling fan based on temperature
1. Navigate to Advanced --> User Scripts --> Output Functions, Set the user script output name, used to to easily identify its function.
2. Navigate to Outputs --> Output Config, assign the Script out X on the physical output, now available through the lua script function io.set(1,true/false)
3. Navigate to Advanced --> User Scripts --> Script Code, edit user script button and enter your LUA code.
LUA code:
-- Script output 1 (e.g. named "Diff cooler fan") — on above 70°C, off below 65°C
local fan_on = false
while true do
local temp = ecu.getf(RTDATA.COOLANT_TEMP)
if temp >= 70 then fan_on = true elseif temp <= 65 then fan_on = false end
io.set(1, fan_on)
time.delay(250)
end
Code explanation:
local fan_on = false - Stores the current fan state.
ecu.getf(RTDATA.COOLANT_TEMP) - Reads coolant temperature from real-time data.
if temp >= 70 - Activates the fan when temperature reaches 70 °C or higher.
elseif temp <= 65 - Deactivates the fan when temperature drops to 65 °C or lower. The 70/65 °C gap creates hysteresis, preventing the output from rapidly toggling near the threshold.
io.set(1, fan_on) - Sets Script Output 1 to the calculated state.
time.delay(250) - Updates the control every 250 ms.
