Radiator Flap On-The-Fly

Controls are available on G-Series vehicles with Radiator Flaps installed from factory

Radiator flaps are automatically opened when Max Cooling is enabled or Antilag is active. In-app Custom Code diagnostic menu can also be used to Open, Close, or set OEM control of the flaps until the ECU is reset or goes to sleep (the value is NOT stored in EEPROM).

There is no ability to control the Radiator Flap using the Custom Code Menu (CCM) at this time.
