Flashing & Safety Notice
Flashing your PCM can be dangerous if not done properly. Follow these steps to help avoid PCM or ECU damage:
- Never flash over Bluetooth or Wi-Fi - always use a hard-wired connection
- Connect a battery charger to maintain stable voltage during the write process
- Do not interrupt the flashing process once writing has started
