Which cars can have their ECU flashed?

[LaHarley]

Generally, only cars equipped with turbocharged engines can have their ECU flashed, as naturally aspirated engines do not gain power improvements from ECU flashing. Many car modification enthusiasts flash programs for their engines, and numerous tuning shops offer ECU flashing services. Below is relevant information: 1. Introduction: The ECU is the brain of the engine, collecting data from various sensors and, after processing, controlling the engine's operation through actuators. 2. Function: The ECU contains control programs that manage engine operation. Flashing the ECU involves altering these internal programs to enhance the performance of turbocharged engines.
