Too Afraid to Ask

Flashing is when a tuning tool updates the car’s computer software. It replaces the factory settings with new settings so the engine behaves differently.

Technical Definition

“Flashing” means rewriting the vehicle’s software/firmware in its electronic control unit (ECU/ECM). In tuning, this is how custom calibration files are loaded so the engine management changes how the car runs.
