Flashing & Safety Notice ⚠️
Flashing your PCM can be dangerous if not done properly. To ensure safe flashing and prevent bricking your PCM:
- 🚫 Never flash over Bluetooth or Wi-Fi — always use a hard-wired connection to the vehicle.
- 🔋 Connect a battery charger to maintain stable voltage during the write process.
- ⚙️ Avoid interrupting the process once writing has begun.
J.R. Jones Automotive & Performance is not liable for any PCM or ECU damage that results from improper flashing or unsafe tuning practices.
