Will Enabling Hidden Features Affect BMW's Quality?

[DiDelaney]

Enabling hidden features in BMWs does not affect quality, as it merely activates functions that are already built-in but officially hidden by the manufacturer. Typically, these hidden features are relatively simple, such as lock/unlock sound confirmation, the ability to operate the navigation menu (including watching DVDs) while driving, displaying engine output power and torque tables, eliminating the delayed confirmation screen on the large display upon startup, and enabling in-car Wi-Fi. Disadvantages of BMW Stage 1 Tuning: 1. Poor tuning may frequently trigger the engine malfunction light. 2. If the ignition timing angle is advanced too much, it demands higher fuel quality. Using 92 or 95 octane gasoline may often result in knocking. 3. Exceeding the engine's output torque and power limits can shorten the engine's lifespan and even lead to engine seizure. 4. To achieve greater power, increasing the fuel injection quantity excessively during ECU tuning may cause incomplete combustion, resulting in insufficient power and a noticeable gasoline odor.
