| 2. | No other tuning or calibration tools can be used with the ECM (including dealer reflash tools). |
| 3. | VCM Scanner, Dealer Diagnostic, and other diagnostic tools will continue to function normally. |
| 4. | VCM Suite can be used to return to the stock calibration and/or update to the latest stock calibration. |
| 5. | If purchasing a new ECM, the Vehicle Anti-Theft System relearn (by a dealer tool) is required once the new ECM is installed. |
