They will program whatever parameters I want , works off Can bus or mechanical senders .
They have a SUPERBRIGHT 7" screen with a optional cover that is same size wise as the Holley 7" screen.
Ive gotten tired of the hard to see Holley screens in direct sunlight .

$1350 for 2 screens and holley cases out the door
I`m working on a better deal for 2 .. if anyone wants any I can try and do a group buy for better pricing .

Do they have a way to put multiple engines on one screen? We’re putting Holley efi on my buddies triple engine o/l and making 3 screens look good is going to be tough.

I`ll ask but putting 3 engines worth of info on one 10" screen that would be crowded

I like both of these screens . they can customize colors and such

Another alternative... I spoke with Kidturbo and he makes a Holley canbus link for NMEA2000 and will plug into a new chart plotter that gives engine data. I might just dump all of my money into a 16" Simrad, Lowrance or Garmin and display 2 engines.

answer

I had set all that up but just didn`t like the how it displayed on the Simrad.
Also you have to use racepack can bus language and that turns off my holley screens but I believe Ken is working on that .

Ken said he’s just getting to the sniper to nmea can adapter. If he can get that together soon that was the plan, run it all to a 12 or 16” garmin.

I bought two nmea converters from Kid Turbo. They worked great connecting two Holley HP to to a single Garmin Chartplotter.
Now I'm considering deleting most of the analog gauges, and use just two chartplotters

I am trying to do the same thing and get my holley to display on my garman. Who is turbo kid and how do i get one of the addaptors. thank you i know it is a old thread.
