Do not rely solely on your battery. If the voltage dips during a write cycle, you can "brick" an ECU. Connect a (at least 20–50 amps) whenever you flash or code multiple modules simultaneously.

A clean power source (minimum 20A, preferably 50A+) to maintain vehicle voltage above 12.5V during coding. Required Software Stack | Werte (hex) | Meaning | Typical Use
