I appreciate the effort you put into this Holley series. I will be watching all of them at least once. THANK YOU!

You’re the man! I really appreciate all the videos you upload. This taught me a lot.

Loving the info man, I’m far from the tuning stage of my build but I’d like to be able to do it myself once I get to that point. Thanks for all time you are dedicating to this series

We appreciate the time you take to do this stuff. I don’t any aftermarket efi or even have a performance vehicle anymore but learning is learning.

Thank you so much Joe this really helps me so much in tunning my VE table. I had a bad fuel filter on E and now I am starting all over.

I think you hit the mark in terms of balance between beginner friendly and technical explanation. Well done!

Joe, these videos are awesome! You have definitely sold me on VE, just from the 30-130 concept alone over speed density. Love the way you explain things.🤟🏻

Just wanted to say thank you. Your explanations are excellent for someone who is new to the Holley EFI world. Keep up the good work.

This video was awesome I was using speed density for awhile on my big block Chevy with a turbo and I ended up going to VE it made the world of difference in the power that it puts down

What a fantastic video, thanks for making it, Joe! I prefer speed density exactly for that trust point that you made. I like knowing exactly what I'm telling the injector to do, not the end result of a calculation.

Just wanted to say a huge thank you! Had a popping noise and missfire on acceleration for the past year I been trying to figure out. Switched to volumetric efficiency and I got to enjoy driving my swap for the first time. Made me feel like a little kid again.

Hey Joe this is super good information that u are giving I just went to fuel injection having a hard time understanding it but I'm gonna stay at it I'm glad I found ur channel I would love to see a video on how to navigate around the Holley Terminator X Seystem just basic stuff how to make changes and save them to the ECU... thanks again great info

Thank you....I learned a lot from this video. This format is perfect for us older blokes trying to learn some of this new thingy ma jigs.

Great vid, always waiting for more!!

Brooklyn Zoo! Love the edits with the Wu from a dude that f*cks with forced induction v8's. Coming from megasquirt, I thought speed density was tuning a VE table, but this expanded my knowledge. Thanks! Keep ol' dirty dropping real facts.

Awesome video as usual Joe👍 Here's my 'experience' (what/how I learned). I've been tuning EFI on bikes for 20+ years and since the only "aftermarket fuel tuning boxes" have all been Alfa-N that's what I learned (first). So since I was used to tuning Alfa-N (and Lb/Hr directly relates to HP) I continued using Alfa-N (on the NA engines) and then Speed Density on Turbos. I was actually very surprised how close my first stand alone fuel table "builds" were (both NA and Boost) but I need to add, that was 100% because I also have several years of dyno experience = thousands dyno runs/data to help me estimate the fuel flow for TPS vs RPM and MAP vs RPM on the Turbos. And as some might guess? the fuel graph/curves end up looking a lot like the HP curve on the dyno graphs. With that said, the first time I tuned with VE I was like, wow this is simple! (because as you said) the numbers in the VE table don't vary much (compared to Lb/Hr)...

Awesome video.. Thanks for taking the time to make these.

Thnak you for this, been watching a couple of videos on this very thing

As usual, great teaching. Thanks!

wow very good explanation your one off my best on this stuff good learning experience 🙏

Another great video. Can you do a video on E85 I'm seeing people putting e85 in the car and just adding 30% to the 've table and leaving there target AFR for gasoline

Legit just learned to turn the calculator sideways at 29:00 ! Haha , awesome! Just tried it, what a trip . Thank you

Thanks for another great video.

Joe there's no doubt in my mind that if you keep putting out good content and info like this your channel with blow up big-time. Good stuff man

Thanks for the awesome content!! 🤘

Great information, and far from boring. The length is the length to get good complex information across, those who complain about it weren't serious enough in the first place.

Dam it joe looks like you are all of our emotional support vehicle through this terminator x ...thank your .. you need to set up some t-shirt or hats so we can support you in all this.....

Great video man you rock!

FFUUU HUUUUUUUUUUCK YEAHHHHHHH!!!! So excited for this video drop!!! Woooot!!!

Joe, dude, great fucking explanation. This cleared up so many things for me, and made some great connections in my brains. Seriously though, thank you for the effort and the time you’ve invested to share this info. My only question is how would you approach VE for nitrous, is there anything special to consider, or is that something that is pretty much handled by the nitrous controller in the software? Thanks again man, please keep them coming!

What kinda of drive data log should I take to get the best info that I could use to determine what I need to adjust ? What can be determined from a datalog I'm concerned about the timing at times I have set it correctly and adjusted the inductive delay its pretty much spot on just not sure exactly what the numbers should be but I'm sure it will effect the o2 results if not correct

I think the cool thing about VE is that your throttle body, intake geometry, any forced induction, etc is agnostic from the standpoint of MAPxRpm. All those things only manipulate MAP (and MAT) so you don’t need to control for them.

I was watching the map transition from speed density to VE and decided to try that with a few global files. It worked well with a few of the Holley files, but when I tried it with mine, it turns it red and it’s all flat when viewing as a graph.

I would like to see some of your welding tips and tricks.

Any idea why my fuel pump/ injector relay clicks on then back off, so no prime then no power, cycle again does the same thing, been driving it for few months with no issues. Help!

Great easy to understand video. Shit in = shit out... if only more people understood that. Self learning though, fixes all (strong sarcasm). I understand a lot people dont want to know and dont care about all the calculations an ecu is doing, they just want their car to run so they can go beat on it. And that is something the Terminator offers the masses for an incredibly low price, and really does do a heck of a lot. A person can literally enter every engine detail wrong, and it will still swing it enough to run and drive. Hard to ask for more than that for $1k. I just wish they offered the ability to measure A/F in lambda, or F/A in phi.

16:45 when you get the .96 from dividing the actual AFR by the target AFR what does that value represent I am trying to understand why that is the value you put in the VE table to make changes Thank you!

You rock dude. Downloading this to my computer just in case KZfaq goes nuclear one day.

Awesome info

i'm looking to switch from duel 750 holleys on my holley hi-ram 12 to 1 motor to be able to switch fuels (race to e-85) my concern is i'm running a 104 center line with a 108 lobe separation solid roller cam. 255/267 duration @.50 with int. closing @ 51.5 do you feel the a holley efi kit will be able to adj properly with the cam i have ? i'm looking to be able to run different fuels on the street if needed based on my location. without swapping carbs or jet.. any info on a proper kit or advice would be appreciated. thanks

Will the Terminator X work on a 1982 Corvette which has 2 throttle bodies and only 2 injectors each responsible for half the cylinders? I realize Terminator X is way overkill but wondering if this would be a good environment for me to learn?

WHy does holley not make a setting to use both at once like ms3pro does:)

Speed density, thats when your drivin’ in sand or snow right? 😂😂 thanks for the video man! Super helpful for me and my projects. 👍🏻

Damn, I bet the editor was worn smooth out by time this was done! 😂 Thanks for the vid!

Great video with explanation of volumetric efficiency vs speed density for Holley ecu’s. Having only tuned a handful of N/A Ls combos, with factory gm pcm’s, the explanation helps. Hptuners will call volumetric efficiency (2 bar, 3bar) speed density which can be confusing for beginners. As you know tuning factory gm pcm’s can be overly complicated, I hope to integrate a terminator x with my gen 3 ls truck one day

Joe great video, and some great pointers one comment, VE can go north of 100% because of what you mentioned but really it’s also an issue with the VE calculation itself as the clearance volume is not included in the displaced volume of the engine which is used to calculate VE. So when you got to 100% VE you are refilling the displaced volume but not also the clearance volume (trapped EGR) when you go north of 100% VE you are completely/more fully scavenging the engine cylinder contents.

What about tuning nitrous with ve

So you are saying that it’s not cool to put 100s top to bottom left to right on my spark table even tho I am 💯? Lol. Thanks joe. I enjoy these style and type of videos. I need that knowledge. Dat nolich.

So can I buy a laptop with this program and have a bunch of slotted screws for everything like a carburetor? 😅 J/K.. Joe I appreciate you sharing your knowledge. (on edit, Subscribed)

Joe, thank you so much for your videos. I watched a few hours worth when I was stuck at the house with COVID recently lol. Now my TT LS 69 Camaro with Holley Dominator runs and drives better than ever. One question: I recently switched to VE from Speed Density. I run E85 and always kept it on the GASOLINE scale because it's what I'm used to looking at, plus it never made a difference with SD. This throws my VE table up into the 130-140 range at WOT. It rides around 68 at idle. The math tells me this is what's to be expected as it's doing calculations for gasoline, but actually having to spray much more fuel to meet AFR goals. If you multiply my VE numbers by 0.67 (e85 to gas conversion), you get VE values that fall in line with what I'm seeing in your video. Is my thinking correct?

In VE mode does the AFR offset vs coolant temp change the fuel calculations even when in open loop mode? Or it ignored in open loop mode totally?

I use to using injector CC. The 40 lbs and 60 lbs is not quite clear. How is that determined?

Doesnt your VE get al skewed when you change from gasoline to E85?

Sponsored by dollar shave club? -jk... Awesome video. thanks Joe.

So if tuning a naturally aspirated ls “5.3” and ve is over 110-121 chances are it’s not a 5.3 but actually a 4.8 ?

Do these video pertain to the sniper efi as well

When are you moving shops bro?

I need about 3 steps under this to understand lol

"There's no right or wrong answers, but if you use Speed Density, wtf is wrong with you?" I'll be honest I always thought SD with it's bigger numbers meant that it gave more precision, but that's probably just Big Number propaganda.

Can I hire you to teach me one on one covidcrew on Facebook
