What it does
Overrides the stock fan-control behavior with editable fan targets and temperature triggers. The author describes a rear-defrost-linked full-fan target for thermal management, additional hot-weather AC logic, and a wide-open-throttle check.
Tested configuration
The author reports using this on a 2023 VB manual, USDM ROM LHBKC50MY0G. Other VB variants and VA are explicitly untested. The attachment is Radiator Fan Override V4 from September 3.
Before using it
Review the feature's fan targets, temperature thresholds and input ownership against your own calibration. Rear defrost may already be used by rotational idle or other features. Do not assume that importing two features makes their shared controls compatible. This is a fan-control implementation, not evidence that every thermal-management combination is effective or safe.
