How to: Holley Dominator Install on LS and setup with Holley V5 Software

[@OutlawChevy2]

This is the best Holley EFI tutorial I've seen yet. Thanks for being so articulate.

[@WestcoastWrenchin]

Happy you liked it!

another great video, well explained, thank you

Subbed. Good video. Awesome car man. I notice your running a 4l80e, did you have to extend the transmission harness at all to get where you wanted?? I'm about to my install on my 91 Z28 with a built 370 80mm turbo and 4l80e and it looks like the harness is a bit short

[@WestcoastWrenchin]

Thank you! The factory holley 80e harness worked like a dream!

@@WestcoastWrenchin cool cool that's just what I wanted to hear. Real world experience. Thanks man

[@Boosted370]

Hey I was wondering if you had any pointers for a guy trying to get my motor to actually idle?? I've been having a bear of a time trying to get my setup to run past a few seconds. Getting a bit frustrating

@@Boosted370 I would start by ensuring every sensor reads correctly when the car is cold, especially the map sensor. After that I would ensure your iac is functioning by taking it out of the throttle body and watching for movement when adjusting settings. The holley in my experience always runs pretty decent out of the box regardless of setup so it seems to me like something unrelated to the tune as crazy as that sounds

[@tjkennedy380]

What about ignition can you make a video on that

[@tjkennedy380]

How does it talk to the gas pedal I’m so confused

[@kaiblue5660]

Hey man this is probably a really stupid question, but when you engine swap a newer engine into an older car, are the o2 sensors connected to the engine? Or are they programmed into the ecu? I just wanna know how easy it would be to go catless without any codes, as far as the o2 sensors go with the new engine.

[@WestcoastWrenchin]

The o2 sensor is programmed to the ecu running the car, catless is no problem but may be illegal depending in your state

Westcoast Wrenchin' thanks man! - followed

I get tired of hearing that you can't run ecm power to a fuse box. How does the factory do it in every production car built.

Go ask Holley then if you’re so confident
