Plug-and-play customization is the name of the game in modern retrofit EFI. Holley has been at the forefront with a host of easy-to-install setups that are all-encompassing with fuel supply, ignition components, sensors, and even digital dashes that are able to work as well individually as they do together.

The latest in digital dashes are their 6.86” and 12.3” Standalone Pro displays. For those who like to keep detailed tabs on every temperature, pressure, and speed, the 12.3” unit (P/N 553-116) is the obvious choice with screen square footage aplenty. Those who prefer something a bit more subdued would do well with the 6.86” version (P/N 553-117).

It’s compact enough to fit in the smallest instrument panels or consoles but large enough to relay critical information as needed. A full color touchscreen on either display allows users to navigate a pack of pre-loaded gauge options or set up data logging.

One thing that sets these panels apart is that they’ll work on non-Holley EFI applications and even on cars with carburetors. An ECU is not required since sensors and signals can be wired to the Standalone Pro dash then configured via pre-defined settings or custom user selections. An internal GPS speed input simplifies the speedometer.

The virtual switch panel can save big bucks on expensive rocker switches and is easily wired via onboard outputs. Kick your cantankerous old gauges and start swiping with the latest and greatest in modern customization from Holley EFI.
