Holley EFI HP/Dominator walk through | Build Tune Race

[@TTBBC]

Great starter video. Please create more of these like a series for the Holley EFI. Maybe making a pass or street drives and review the logs making changes to see the results.

[@BuildTuneRace]

That's a good idea! I can tie that in with pulling the log and saving it.

[@TTBBC]

Build Tune Race thank you definitely looking forward to that video.

[@doctorcowen1083]

Very informative! Not very many people out there doing in depth videos on some of the aftermarket ecu's. I like your videos because you explain what the cars are doing and how you're going to change the tune accordingly. This one will definitely help get a starting point if I go with Holley on my project.

[@BuildTuneRace]

Michael Cowen Thanks Michael! Glad you enjoyed it!

[@bryanleverett2830]

I was going HP tuners. But after I downloaded the Holley software, it sold me. I came from strong arming an SRT4 mopar ECU to a Cobb access port for fords, and seeing the Holley made me take the dive. That being said, it’s more complicated than Holley would prob like you to believe. Buts it’s also Infinitely better and less complicated vs a Cobb accessport (or prob any other flash tuner for that matter ). Anyway, just wanted to say this is a great video. I’m sure it’s going to get a ton of views over time because I’ve searched for a video like this about 15 times in the last 3 months and mostly just come up with Holley videos of guys snapping connectors together and running simple N/A motors off the 3.5” touchscreen base tune and calling it a day. Truthfully, I already knew 90% of what your going over, but to learn anything is always a good thing ( I just tuned my buddies ford Mavrick with a GT40 302 and Paxton SC with a blow through and Holley super sniper Efi a few nights ago ). And it’s works great. My request is the same request someone else already made. Maybe go do a datalog, maybe even get some in car video while doing it ( how fast the car is or looks isn’t really relevant ) and show how the “bubble” moves around the scales live. And then go over the datalog with what you show in the video showing up on the datalog. Another tip.... since most people are looking at this for LS engines ( 1/2 at least ). Sloppy Mechanics (Matt) gives away his tune on the 1000whp 6.0L Colorado for free. This gives you a lot of great info. Like how and where to put tables in for an E85 sensor. 4L80e shift tuning with a lock up converter. Some examples of nitrous control ( one of my fav parts is that he has it yank timing A LOT when the nitrous engages, and then feeds the timing back in over rpm. It reduces the shock load on the bottom end and driveline.). So a lot can be learned for looking at examples of other people’s tune, even if they do not apply directly to you. Great video. Thanks for doing something unique that even Holley hasn’t done. If you can go any deeper ( I realize your in a race car and that only requires so much depth ), then I will def watch those too. Sharing video now :)

[@BuildTuneRace]

Thanks Bryan for the great reply I truly appreciate it! I will take everything you mentioned into consideration the holley is an awesome system and I keep learning more and more each day! Half of the battle is understanding the wiring as I ran into some issues last night on anouther guys car but getting through it! I would like to post complete how to at some point on boost control, nitrous control the new staging in v5 ect! I will do a data log video as soon as I can. I think that will bring alot of value to people! That's awesome your learning it as well! I really enjoy playing with it but sometimes it gets frustrating, but when it works it works extremely well! T

[@bryanleverett2830]

I’ve watched from a distance, Jay from real street tune my buddies twin turbo viper. It runs a zillion dollar Motec. And it’s 100x more complicated than the holley. My Cobb race tuner software is 10x more complicated. I think the super sniper is the way 90% of people should go ( unless you have a hemi, coyote, LS ). Sniper uses 90% the same software. Maybe try to do the traction control like Matt did and go more into it. It’s the best feature on my Cobb tuner ( 340whp fiesta needs ign based traction control ! ). Also maybe do a walk through on adding a random temp or pressure sensor. I’m personally using AEM 100psi sensors for fuel and oil pressure but you could use anything. Make it something weird if you can lol. Or even map the sensor out yourself with voltage/pressure-temp and then enter it into the Holley. Just ideas for content.

[@95turbostang21]

Awesome video very well explained and easy to understand this is my favorite video on explaining how Holley works straight to the point and kept it simple with not using big words

[@BuildTuneRace]

Glad you like the video! Thanks for watching!

[@g-rodcustoms2448]

I sure Appreciate your videos and your time that you put into them. Sure helps a lot. I have a 1940 coupe that I'm building single s475 forged 5.3 and im getting super close to firing it up and it's been nerve racking but with the help from your videos, helps me want to tackle it with just a little bit more confidence lol. Thanks again.

[@BuildTuneRace]

Awesome to hear David. Glad I can help!! Good luck with it take baby steps and you'll get it! Shoot me some pics on Facebook or Instagram if you get a chance!

Me too. Just getting going on my lsx in my Nova

[@onefastermonte85]

Build race tune, do you have a Facebook page so we can post up Holley issues.?

[@917Jolly]

Awesome vid man. I'm a newb at the Holley efi and have it on my N/A foxbody. This answered alot of the questions I had! Thanks

[@BuildTuneRace]

Your welcome! Thanks for watching!

[@onefastermonte85]

Could you do a holley efi (dominator or hp) video on coolant enrichment or fuel modifiers? I think this is a confusing topic, but is important when it comes to the self tuning aspect of the holley.

[@charlieodom9107]

Pretty good video!!! Just a personal opinion, but I try to keep all my fuel maps to within 3%, so I normally limit fuel to +10/-5. Another thing I do is to blend the fuel map on initial tune, before going WOT, then add 10% to any WOT cells and raise the fuel adder to 20%. This keeps the thing from falling on its face and possibly burning a piston or worse for the first WOT run. The Holly EFI system really works well, and is so much easier to tune than HP Tuners, albeit without all the fancy parameters.

[@BuildTuneRace]

Sounds about right! Thanks for watching!

[@supadavee30]

Keep doing tutorials on the Holley

[@BuildTuneRace]

Sounds good!

[@wesboyd7416]

Thanks for the video, it would be helpful to see how you start the base maps for fuel and spark and what exactly your looking for as you take fuel in/out and add timing how much safe timing we should run with na/boost/nitrous

[@Handlehandlebars]

quick question I'm considering setting up my 427 sbc with an HP mpi system...my engine only pulls 5hg at idle...from my understanding 02 sensors read very lean at idle with a big cam .will low vacuum like mine be able to be tuned at idle and will the map sensor run correct at other rpms with a heavy cam? any info would be great

[@minnick99]

You shouldn't zero out your fuel modifiers. Learn will work once the car is warmed up and the coolant temp enrichment goes down to 100%. You still want to have additional fuel when the car is warming up. Enrichment can taper down to zero around 160°.

[@BuildTuneRace]

Mike Minnick makes since I haven't played with the fuel modifiers a lot. Ever since I started I learned somewhere to just zero the tables then you can go back and adjust accordingly. But it makes since that once it would reach temp it would allow the learn function to start working again!

[@177SCmaro]

It says you must select the correct brand O2 sensor or you could damage it what sensor comes with the Holley HP? They don't bother to tell you.

[@BuildTuneRace]

You can get it with the Bosh or NTK should have it etched on the sensor

[@177SCmaro]

@@BuildTuneRace It's not etched on the sensor which brand, it just says "Holley" and then I assume a part number. The other end is apparantly a Delphi connector. Looks like I'll have call Holley and ask. Seems like pretty vital information they left out.

[@BuildTuneRace]

@@177SCmaro if you know the part number of the kit you ordered you could look it up that way too. Should say in description bosh or ntk. The ntk is the more expensive kit designed for ethanol and methanol

[@177SCmaro]

@@BuildTuneRace I'll look into it, thanks.

[@schpenxel]

FYI the LS coolant temp sensors are off at ambient but tend to be more accurate once you're at higher temps,, so be careful offsetting the entire curve like that.

[@evanlikestephen4441]

I guess this was my comment, Thanks man I really appreciate it!

[@BuildTuneRace]

You and anouther guy! I will try to do more in the future as well thanks for watching!

[@evanlikestephen4441]

Build Tune Race no problem man you make good content

[@wickedmicro69]

Do you have to have the holley Hp hooked up to the car and harness to do initial setup

[@BuildTuneRace]

You'll need atleast power and ground hooked up and probably the keyed IGN. Not 100% as i have not tried it myself.

[@luismora4229]

Great Tutorial, I learned a lot from this.

[@r3rd698]

Do you know of a base map set-up for a 572big block? Just got a Holley hp efi set-up thanks.

[@BuildTuneRace]

I thought there was a big block base tune start up file in the holley you could try that if it seems close to your combo. Just need it close enough to get started then you can start dialing in the fuel table from there if you find that it seems to be real rich you start by pull 20% out of the whole base map and go from there

[@jesusavelar8034]

Awesome video bro thxz for sharing the knowledge.. I have a terminator Ls mpfi it keeps telling tps errors 109.. do you have any idea what it means? Also wen I press on my pedal my throttle body blade don’t open? But on my 3.5 it shows it working?

[@nxt_sean1168]

Build Tune Race oh yeah it will

[@Acekreation]

Can you answer this. A tuner is trying to charge me around $600 for a tune. Can I get close to that tune level if I buy this system?

[@BuildTuneRace]

Super hard questions with a ton of variables. Depending on system and what your trying to accomplish your level of tuning knowledge and the combo your trying to tune. If you can find a base tune really close to your combo and its a simple combo like a simple N/A with some learning you could probably get by. If your building a complex combo boosted or something high horsepower and you don't understand efi tuning your probably going to need someone to tune it. The Holley has a awesome self learning tuning strategy but it is not a plug it in and it will 100% tune itself unless its a simple combo even then a real tune will have benefits. Hope this helps!

[@zombie95xx]

Say I want to put on of these systems of a ford Fe big block would it work ?

[@BuildTuneRace]

Yes with a digital ignition system you are able to! Or you can. Convert it to coil on plug as well!

[@TheRdub82]

Thanks for the i formative video. I have an Boss 351W based stroker 408 that I want to convert to Holley Dominator efi with port injection. I'd also like to bump compression ratio to 12:1 and run flex fuel as well. Eventually looking at doing a Procharger D1-X too. Gonna need a dual sync distributor or can I go coil on plug conversion? Thanks

[@cadeflorez3457]

TheRdub82 why don’t you ask the LGBT community? They would surely know more about your ford power plant.

I was thinking of upgrading the flux capacitor on my DeLorean. I was wanting to know if I needed to change the blinker fluid before I put a wet shot of NOS or would it blow the welds on the intake?

[@floridasaltlife]

How much Documentation comes with it. I have never saw good Documentation for the price paid. Had BS# and Seed Pro in the past and was a struggle at first. Hoping this has help menus ?? Great Video on The Holley HP/Dominator

[@BuildTuneRace]

The holley has really good documentation you can download the software for free and go to the help menu and it will pull up all the documentation also if your wiring in accessories holley has documents under the products on the website too to help wiring and everything!

[@issorjmedia7770]

If you pull/add boost out of it in the boost control section does it pull/add fuel automatically or do you have to do it yourself

[@BuildTuneRace]

It will reference the new area of the fuel table to match the boost level so all the fueling is already dialed in from initial tuning.

[@Sargen013]

Awesome video but you skipped over the whole reason I watched it. Could you please explain how to set up a base timing table?

[@BuildTuneRace]
