Is Holley EFI Really Self Tuning?

[@reminoel483]

Tuned my first forced induction car with TerminatorX yesterday and i couldn’t believe how smooth everything went Stopped at 12psi 12degree. Stock 5.3 with stock cam and ebay GT45. Made a safe timing table off the top of my head ans did use ‘’seft tune” then manually made the fuel table pretty. Everything went perfect

[@webberfan1234]

Put some more boost in

[@95turbostang21]

Holley works basically like a factory ecu with the long term/short term fuel trims, holley just gives you the ability to change settings and makes it easier to understand each setting (PID) with some extra features

[@JingleBop]

Except it has a wideband sensor instead of a narrow band, allowing it to continue adjusting even when commanding outside of stoich

[@echadmiyodea]

You're exactly right about everything you said in this video. This is great to see online.

[@1320pass]

I have an old TPI Camaro engine laying around, I'd like to play around with this aftermarket ECU stuff. Probably a silly way to start but Hands On is about the only way I can learn. I have a better understanding through your videos. Thanks Joe. 👍

[@rcadd1ct]

Currently fighting the new project woes on a wizard tune. Definitely helps get you past the stupid installer issues (me). Easy to blame the software, but then find out the throttle WAS actually hanging and not the tune. DOH!

[@user-jf7uu8ji4p]

I am old school and was on the fence which way to go for Eli or natural aspiration carbaration. OMG YOU MADE THAT EASY!!!! Thank you so very much!

[@corvettefever360]

This guy should have more followers. And I'm not just some weekend warrior by any means, so I can say this guy knows his shit. And another thing that gets people caught up on "well this guy said this & another that" etc etc. Which doesn't necessarily mean either is wrong, just different ways & or opinions on how to reach similar or the same end goal. Everyone eventually learns their own ways. Then of course you get weekend warriors who watched 2 videos, heard some things from others, & have an uncle who's half sister has a friend who knows this guy who said this & that, & so now they are experts, start making videos on instructing others on how to do things. This is a real real problem. I personally think these people should be called out & have their channels canceled!!! Because this can be costly and quite dangerous. I have no problems with those beginners who are starting out and making videos about it, but are fully open about being beginners. I've seen videos of people who straight up admit they are learning as they go along with you making videos. And to me that's perfectly cool. But don't betray yourself as some expert when you are not

[@norbialaniz8442]

Great segment

[@prettyvacant2729]

Yeah I got sucked in with the self tuning marketing. On my standard motor, loved it. Could have become a sales rep I was so impressed. Then, threw in a built motor with timing control and Duh. Months of hassle, poor running and aggro. Now I'm off to a tuner to tune it. Which is exactly why I ditched a carb and spent 4x as much on the full efi setup; to not have to tune it every so often. Thanks for this video - at least now I know my 1500 bucks isn't being wasted on a dyno day.

[@robostyle9773]

Love your videos, i am watching Tune The Trilogy now, best $$$ i have spent so far. Really appreciate it

[@sorabsoul2684]

learn table not being zero was making me think something was wrong, thank you for clearing that up!

that seems to be a big misconception a lot of people have, so hopefully this will help clear that up for people!

I’m 18 years old never worked on a car other than in hs for class I took on a 69 302 coupe that had a holley sniper efi every-time I turn the key it squirts fuel, and starts to leak I was wondering if any ever experienced this problem I’m not sure if it’s because of the fuel line or something else

[@jacobvanhalteren7452]

I heard some scenarios where guys washed the cylinders on brand new motors or hydrolocked stuff because it kept adding fuel

[@ctuning]

Wonder how many engines that blown up due too failing Lambda sensor and zero "tuning". The "self tuning" as advertised, ppl do really think they do not need to touch it after installed.

[@UpNorthCatsFan]

So I have a dominator, but also have a separate wide band that can also read in lambda. Why most don’t get their own is beyond me

[@shannonsisk]

Nice editing and great info

[@701garage]

yes if you have a spot on tune it should self tune to sea level changes. Keep the corrections % low

[@NoFox_Given]

I have a brand X ecu MS3 😂 my fuel tables are setup for switching so I have table 1 strictly NA and table 2 is all in boost so I could do as you suggested… have higher resolution. I’ve been told it was a waste of time but it makes me feel better 😂

[@jesscneal]

Excellent vid Joe. Cleared up some things for me for sure 👍

[@irabel01]

Exactly what I needed to see

[@Flitzer514]

I haven't had an O2 sensor fail, but I did have a header gasket fail and it made my terminator go ape shit. My correction is set to 25%. Thankfully this happened at home. 😀

[@luc2go]

If my 78 Dodge b200 with a 318 doesn't pass California smog, and I know my engine is good, should I consider this instead of tuning Thermoquad carburator?

[@jasonbrinegar6759]

Hell Yes!! Preach!! Look at them sales tho Boi!!😅 And let's not forget, for an additional 79.95 VZ analyze will tune for you too!! 😁

[@cobrabuilder9336]

In Holley's book self tuning = Matching the desired afr.

[@timweb1510]

What a strange comment.

[@8t8GTA]

@@timweb1510 lol, I meant I really thought it was self learning, Now I know otherwise.

[@GaryDePriest]

Thanks for this and your "which Sniper..." video. For a carb to Super Sniper conversion, which 3 additional sensors would you want added in order to provide the best NA tune? Fuel Pressure, Crank Position, ???? Want to make a video about it and why?

[@KCadbyRacing]

All of your videos are great Joe 👍 I've been tuning Holley EFI on motorcycles for over 11 years and I have only tried Learn twice. Reason(s) being 1: since I had already been manually tuning bikes for decades I was used to tuning manually and 2: I didn't like what learn did to the fuel table the couple of times that I tried it. The first (and only) time I tried Learn on my dyno, I was happy with what it did on the 100% TPS pull but after doing the next pull at 90% TPS, I saw that Learn "ruined" what it had just done on the 100% TPS row...

[@JoeSimpsonAtTempest]

That’s basically my experience. It really likes to fight it’s self

[@nosnerd1967]

Another great vid

[@tonyimbarrato5325]

Thanks Joe !!! Awesome presentation and great insight on how the system works. I would assume the Atomic 2 has the same tuning capabilities? I just installed my A2 and it runs like a champ, I do A lot of refrigeration controller programming so this just gets me thinking I’m leaving technology on the table.

[@hagalien]

I love youre new setup!!

[@jamesparkerfpv435]

thanks Joe!

[@michaelyunker1642]

Does all this apply to the FAST Ez efi 2.0? Is there anyway to tune that system?

[@lrmmorgan]

Not today, but im definitely getting your course! And thanks for offering it!

[@callofgeorge]

unrelated to this video, but i can't for the life of me find your video where you talked about why you chose holley as your main ECU of choice. i remember you compared other ecu options. wanted to go back and see what your opinion of haltech was. a buddy has a nexus r5 in his civic that i'll be wiring for him.

[@JoeSimpsonAtTempest]

Search “Holley efi vs everything” it’s an older video

[@callofgeorge]

@@JoeSimpsonAtTempest thanks Joe. remembered it was older and skimmed through but didn't see. couldn't recall the title of it.

[@davelowets]

I personally think that the "self-tuning" feature is better for an N/A engine.

[@dhangejr]

How much do you charge for a remote tune ? You seem like you know what you are doing

[@jessemarinjr6374]

HELLO JOE ,GREAT VIDEO !!! DO YOU KNOW ANY GOOD SHOP HERE IN LAS VEGAS THAT KNOWS HOW TO TROUBLE SHOOT THIS HOLLEY SNIPER ON MY CORVETTE ?? PLEASE LET ME KNOW ? THANK YOU JESSE

[@astrawally8448]

If you believe self-tune entirely replaces the job of the tuner and means never having to connect a laptop then yes, the Sniper is not self-tune. If you believe self-tune means that with a handful of parameters, you can get into the ball park and get running quickly, then further tune and refine, then the Sniper does a good job. How helpful is setting base maps/configuration will depend on how wild the engine is, how well the EFI was installed and how stupid the person setting it all up is.

[@kevinwest3689]

I got real lucky, i got the holley because i have no computer, nearest tuners 200miles away. Wider depth work like a champ for 3 years. Head gasket falling trashed o2. Other day. So im wanting to add parts ive been collecting for the 6.0. But im worried im not going to be as lucky if i do. Its my daily. What di you think my chances are? 799's Truck norris Trailblazer s s- ninety three millimeter throttle body. The injectors i picked up are kinda large 93 because i intended on Installing all this with the turbo at once. But don't have everything i need yet for it. Would I be better off just keeping my little throttle body and truck intake Until I can get or afford a real tune? I want to learn to do it myself. But i'm a little slow and I need it now.

[@BreaHouse-pb5wz]

So you said they selected the wrong MAP sensor, is that a food indicator of why this one absolutely drops out?

[@JoeSimpsonAtTempest]

I just misspoke. It’s the right map sensor it’s just a 2.5 bar sensor on a Na car which is just a weird choice but works just fine

[@todds5956]

Do you offer remote terminator x tuning?

[@LennyAllen-zw6wg]

You know any shops in clearwater fl that can troubleshoot issues with efi???

[@marclaforet-zn8zg]

thanks, you just talked me out of a sniper!

[@theoutlaw2395]

Just out curiosity, why did this talk you out of a Sniper? I'm ready to pull the trigger for a Super Sniper Stealth for next years project. I've been reading reviews on EFI and talking to guys at the car shows, and the top choices seem to be FiTech and Holley. The online forum reviews seem to be about the same complaint 50/50 against Fitech and Holley (what someone says bad about FiTech, someone can say the same complaint about Holley, maybe they get their onboard computer from the same place.) I have heard that a hot rod tuner would be able to get better performance out the EFI after it's up/running, whichever brand it is.

[@nickortega3182]

How much you charge for a tune

[@TyrellLewis-ie5bc]

Where are you located? Can I pay to have you tune my stock LS3? This stuff seems so complicated

[@Mikson-p1t]

Can I make 1000hp using a wizzard tune

[@woog74]

Is this really a fair demonstration of the self tuning if the customer put the wrong MAP value in? Not trying to attack you in the least. Just wondering, how could any ECU have a chance at proper air/fueling with the wrong MAP value entered?

[@JoeSimpsonAtTempest]

I actually miss spoke in the video- he entered the correct sensor but bought a 2.5 sensor for whatever reason. (Which would work just fine, the snipers use a 2.5 bar sensor) As far as the learn table example this is a very real world i see it several times a week scenario. I wish i could go back and edit the video to explain the sensor scenario correctly

[@davelowets]

Get a map sensor that is as close to your maximum numbers that it will see as possible, and you'll have more resolution for it to "self-tune" with.

[@momentummotorsports6137]

Great vid as always i totally agree with you

[@davidcraft4909]

i know this might be off subject but I watch your videos and I feel like you would know about this kind of stuff. Is there any reason for a tuner to turn off fuel enrichment when tuning a car. More specifically a car that came from the factory supercharged and the only thing changed is a bigger supercharger? I'm just trying to figure out whether or not the proper procedures are being done. I know this is a vague question, but I don't know anything about tuning sort of, but I know how things work and I don't see why anyone would ever disable fuel enrichment. I only have experience with carbs and to me that sounds the same as taking off the accelerator pump or blocking off the power valve or disabling the metering rods in a carb, and that makes no sense in my mind.

[@JoeSimpsonAtTempest]

Turning off accel enrichment would make the car run awful

[@turboboy-oq6xe]

Does this apply to the sniper throttle body

[@JoeSimpsonAtTempest]

Yes

Hey I have a carbd mustang 347 10:1 and just bought a Paxton supercharger and I’m looking at switching to the terminator x stealth 4150. It will probably be making between 5-600hp and in the future I’d like to be able to turn it up. Does that seem like a good choice? The system is on back order till may. I will also pay for your course and all that knowledge.

[@JoeSimpsonAtTempest]

if your stuck on throttle body injection it should be. if it was me id convert the manifold to port injection and run a HP or dominator ecu - but thats obviously more expensive

[@6spd85notch]

@@JoeSimpsonAtTempest i figured I could use the ecu later on down the road on a multi port setup. Holley said just buy a harness and I could run anything basically off the terminator x. Thanks for the help.

[@astrawally8448]

Tuned a 360 Chrysler Magnum with a B&M Supercharger + 150hp NOS kit controlled by the Sniper Super Stealth 4150 4 Injector, and it runs very well. As this video says, the wizard tune is fine to get it running but it will need some work to refine, particularly idle and low-mid load/RPM.

[@v8tergt653]

Does Learn make any change to the table or affect anything in any way if you dont send it to base?

[@JoeSimpsonAtTempest]

It doesn’t make any change unless you transfer however it is applying the correction that it shows/stores in the table real time

[@v8tergt653]

Isint that what Closed loop does? Correct whats on the table +\- to get to whats commanded on the target table?

[@JoeSimpsonAtTempest]

@@v8tergt653 think of closed loop as short term fuel trim and the learn as the long term fuel trim. Similar, but 2 different things. Oem ecus work the same way

@@v8tergt653 technically yes, but it’s rare that the math works out 100%. It can change for every car but if i had + 5 and + 5 i would probably add like 7.
