Holley Pro Dash layout questions

The Holley EFI Pro Dash in both sizes, 12.3 inch and 6.86 inch, including the standalone versions. Both sizes use the same screen resolution, so one layout works on either. The designer warns you when text will be too small on the 6.86.

Not right now. Gauge Garage makes layouts for the Pro Dash only. The older 7 inch and 5 inch Holley dashes use a different screen size.

Yes. The Pro Dash works with Holley HP, Dominator, Terminator X, Terminator X Max, Sniper and Sniper 2. Some readings only exist on certain systems. For example, a Sniper doesn't read oil pressure, so that gauge needs its own sensor.

Yes, everything is free during the beta, and you don't need an account.

Holley lists the 12.3 inch Pro Dash at about 11.5 inches wide by 4.25 inches tall, and the 6.86 inch at about 7.6 inches wide by 3.4 inches tall. Check Holley's mounting template before you cut anything.

No. The dash draws the needles itself, and they're red. You can design everything around them: gauge faces, numbers, colors, chrome rings and logos.

Yes. Logos, text and background photos are part of the picture behind the gauges, so they can look however you want. The live numbers the dash draws use its own built-in font. Only use logos and photos you have the right to use.

Wire your fuel level sender to one of the Pro Dash's inputs and set it up on the dash. In the designer, add a gauge with the E, 1/2, F scale. Then either enter that input as a custom channel, or pick the input for that gauge on the dash after you load the layout.

Yes. Add a warning light in the designer, pick what it watches (for example oil pressure below 15 psi, or coolant above 230°F), and choose its color, its size and whether it flashes. The dash lights it up itself, just like it moves the needles. To show a symbol instead of words, like an oil can or a battery, load the layout, then customize that light on the dash, tap its label and pick a symbol from the Sym keys.

Yes, if those signals are wired to the dash. Connect each one to a Pro Dash input and set that input up on the dash (Holley's manual lists which inputs take a 12 volt signal). Then add a warning light in the designer that lights when the input is on, and pick that input as its channel. Arrow and high beam symbols are on the dash's symbol keyboard.

Yes. Save the screen from the dash to a USB stick (Customize, Layout, Export), then open that file in the designer. Round gauges, digital readouts, bar graphs, warning lights and the shift light bar come in. The background picture isn't part of that file, so upload it separately if you want it.

Loading a layout only replaces one screen, and it doesn't change the dash's software. Back up first (Utilities, Backup Configuration) and you can put your old screens back any time.

No. The Pro Dash loads layouts from a USB stick, so you download the layout and copy it over.

In your web browser, automatically. Click Save design to download a copy you can open later or on another computer.
