HP Tuners User Defined Parameters License

Edit the tables HP Tuners hasn't defined yet. User Defined Parameters is a one-time feature unlock for your HP Tuners interface. If you know the location of a switch, scalar or table in a controller that VCM Editor doesn't expose, this license lets you define it yourself and edit it inside VCM Editor like any other parameter.

This is a digital license, not a shipped product. Enter your interface serial number at checkout. We apply the license to that serial number and email you when it's ready, during business hours. Then open VCM Editor and resync your interface to pick it up. Digital licenses are non-refundable once applied.

How it works

1. Define your parameters in TunerPro, the free third-party definition editor, and save them as an XDF file.
2. Open your HPT tune file in VCM Editor.
3. Go to Edit, then User Defined Parameters, and open your XDF file.
4. Your parameters are imported and ready to edit.

Parameters defined outside the controller's allowed address range will not import and cannot be edited. If you'd like a parameter added to VCM Editor permanently for everyone, HP Tuners takes those requests through its support team.

Who it's for

• Calibrators and shops working on controllers or features ahead of HP Tuners' official definitions
• Tuners who have reverse-engineered a table and want to adjust it without leaving VCM Editor

If you tune well-supported vehicles with the standard parameter set, you don't need this. The license is tied to one interface serial number.
