Unit Handling
Haltech logs store data in specific units based on the CAN protocol. UltraLog:
- Automatically detects the channel type
- Applies appropriate conversions
- Displays in your preferred units via Unit Preferences
Min/Max Values
Haltech logs include min/max metadata for each channel, which UltraLog uses for the legend display.
Channel names
With field normalization on, these Haltech names show as one standard name. From the OpenECU Alliance Haltech NSP CSV Export adapter v2.0.0.
