Data Log Playback
The Holley EFI Pro Dash will play back logs that have been locally recorded using the 'Record' button or
retrieved from an HP or Dominator ECU. Pressing the 'Playback' button on the right side of the dashboard
screen allows you to play back these logs from the dash's internal storage or a USB flash drive.
Firmware Upgrade
New or additional features developed by Holley can be added to the Pro Dash by updating firmware. These
updated firmware files can be obtained by contacting tech service (270-781-9741 or 1-866-464-6553) or they
may be downloaded from our website (https://www.holley.com/support/resources/#Fuel_Injection).
To perform a firmware update, follow these steps:
1. Extract the contents of the firmware .zip file onto the included USB flash drive (unzip files and put on
USB flash drive). Always use the included USB flash drive as others may not work properly.
2. Connect the USB flash drive to the USB cable on the Pro Dash.
3. Select 'Update Firmware' from the Configuration menu and follow the on screen prompts. The firmware
will automatically update.
4. Verify the version number using the About button after turning the dash off and on again.
