Problem
If you receive the Reader upload request :x7F negative response code error, this likely indicates your vehicle has been previously tuned and the ability to read the tune has been disabled.
Resolution
| 1. | Please start a Support Ticket. |
| 2. | Obtain a VCM Suite Infolog while connected to the vehicle. |
| 3. | Locate and prepare a Debug.dat file from your PC. This is located in Documents > HP Tuners > Settings. |
