Holley Efi dash virtual switches and customization

How to customize your holley dash and add custom timing retards and switches to your dash

[@reid8301]

You have the best content on Holley stuff. When I’m done watching your videos I actually understand what the heck you said. Everyone else over complicates things. Thanks. Hope you get into your new shop and get some training going. I’d love to get in there and learn from you.

[@rmsracing5860]

Appreciate your videos man. I watch your channel everyday while im building my tt foxbody to gain awesome info. Learning everyday from you 🤙🏼

[@MasonQQQ]

Great video. Thanks man. Looking forward to building my car with Holley.

[@mattcasey6187]

Most helpful videos on YT period. TY!

[@flatbrokemodsquad4241]

Very informative video. Thank you.

[@SoftiesTruck]

Thank you!!! I have an LSA blower that I want to keep cool.

[@fastass68camaro]

Thank you so much for the videos, also do you think it’s ok to a virtual button to arm the nitrous system, or do a actual rocker switch?

[@justinwall8708]

Great video Devin!

[@kolemieux]

Exceptional Video!!!!!!

[@alettoco]

Hey Devin, I really like your videos on the Holly system. l have a question about virtual switches. Can you make a virtual switch to arm and disarm rev limiter #1on the pro dash

[@barryc2307]

Could you clarify something for me on the virtual switch usage. When you go into the settings for the efi ecu and you pick a input to assign it to for the dash on the pin map, like you chose Switch #1 for the Retard 1, that doesn't effect any of the dash inputs or output circuits where you would connect a wire for some other function, correct? It just gives the ECU a place to look for the signal?

[@dqniellourenco6162]

Great videos and advice . I am looking at dash options for my terminator they have the regular for 700 and pro for 1000 which do you suggest I know the cheaper one needs a 250 input add on . I removed all the gauges and no speedometer it's a street car

[@davelowets]

Well, then why would you cry over $50, just get the bigger one.

[@CrazyCowboyBuilds]

Do you have a contact for Ryan who does custom gauge layouts? I just got this 12” for my terminator x and really want to make a sick gauge face

[@moose1992caprice]

Does this information work on the 7 inch dash too? I'm assuming it's the same on the 6.8inch dash.

[@wimsurf]

this would have me tinkering for weeks, best not get to it until I actually have a driving car

[@rut2nutkp]

Would the same principles apply to the stand alone unit ?

[@Juan-VargasJV]

Wow

[@Im-Not-Gay-No-More]

Is there any way to make a virtual switch momentary??

[@E85_GTO]

Is there any I can create a switch to arm my dry progressive nitrous system with my Holley 12.3 screen? If you already have a video that would be awesome.

[@kansascityscarecrow]

Can you have it set for just EGT sensors only?

[@randelholt7341]

Can I add a virtual switch on top of my manual switch in the Pin Map. So it can work either way?

[@0347kali]

Can the settings be done on a laptop and them uploaded?

[@genenewton7802]

With the optional input output wiring on the dashes(I have a 7 inch) your hypothetical fan switch can go straight to the relay correct? HP users don't have as many I/Os.

[@theholleyefiguy]

Yes exactly

[@genenewton7802]

@@theholleyefiguy, so you utilize the ECU when you need or want to add "logic" like a retard table, or multiple conditions but simple on and offs can be left to the dash I/Os

[@Blizzard020]

I will be doing the same thing with my hp. I’m trying to find a way to tap the signal on the map sensor to trigger my 2nd fuel pump without using an output.

[@davelowets]

​@@Blizzard020You would NEED to use an output. How else would it be able to communicate with the relay for the pump?

[@lilrickygsxr750]

Can you set a data log start button on the dash?

[@Ranger4banger]

I know this is an old vid. But I'm trying to get my dash gauges to match what's on the laptop. Such as battery. If I hit customize on the battery, the sensor is set to battery, but I think it's showing me some other reading. Everything on the laptop is good. But everything on the dash is wonky, and all the gauges are "set" to read all the correct sensors

[@adrianlaverick8040]

Can you use these switches to control things such as headlights or aux lighting?

[@Nicholas-im8bd]

Adrian Laverick through relays... yes

[@jcnpresser]

Does the Holley terminator have all these features as well?

[@Ribbityibzki]

This dash will work with the Terminator. All these features have to do with the dash, not the ecu. You can buy the dash to go with your terminator and have all this neat stuff.

[@swaterman08]

Would be cool if you could get a cheaper LCD for the dash and gauges and use the touch on the console like a Tesla.

[@Nicholas-im8bd]

Stephen Waterman put a window 10 tablet in your console...

[@sonikempire]

For the life of me i can't add an CAN switch output from prodash to trigger a fan output on the dominator. Says no switched outputs are enabled.

[@gearjunkie3412]

Can you run your directionals thru it

[@theholleyefiguy]

Yes

[@lebronmassey42]

Does it have or Can u add video input to monitor back up camera or whatever?

[@brennenreed3759]

No

[@thosebrosgarage]

You still a dealer? Do you have a site? I can’t find any contact info on your channel.

[@theholleyefiguy]

hcrinnovations.com yes we are a dealer

[@mgmx2099]

You're about to screw this up, just hit ok.

[@GoFasterHD]

I didnt see a push button option? It would be kool if you could start your car through the screen.

[@Mars-pp9cx]

It doesn't look like there is a push button option, but you can do something even better: you can add a virtual kill switch!

[@GoFasterHD]

@@Mars-pp9cx I switched to fuel tech,

[@longrangevoodoo4480]

Zero mention of price. Automatically means its too expensive.

[@theholleyefiguy]

This video is 5 years old How would a mention of price be relevant today? I’m not trying to sell you anything, this video is to educate you on how to do something
