- What Holley Terminator X Do I Need?
BurnDown Ep. 126
In this episode I go over what you need to know in order to buy the right Holley Terminator X for your application. I get this question a lot. I hope this clears things up a bit and takes away some of the confusion around what you need to order to run your specific LS motor and Transmission combo.
If you have an questions leave it in the comments section and ill get back to you.
Thank you for watching!

Excellent video! Very informative! Thank you for posting!
Thank you for watching. Glad you enjoyed it. I got this question a lot so I made a video for the new guys.
Great video! Thanks! For us noobs this was helpful!
Thats exactly who this is for. Good luck with your project!
Great information Dane!!! I have been reading up on my 5.3 and was looking for the lowdown! Makes me want to swap mine in sooner lol
They work well Matt! Youll be happy when you get one.
Price of shit
Really helped me out thanks for the good vid!
If you have any questions let me know. Ill help if I can. Thank you
Helped a ton!!
I finally go around to making this video. I get this question a lot. I know you were one of the guys with some questions so glad to help man.
Thanks mate. Helpful for sure. Summernats poster too gets a thumbs up :)
Its a real poster! One of my guys that follows me on IG mailed it to me!!
Nice work. I had to come back to this video a few times.
Glad it helped you out.
This has to be one of the best explanation for the ls wiring harness and the holley x. You explained it better than Holley awesome video
Thanks man I appreciate that. I get the question a lot so I made this video and send the link to people when they ask me😁
Good concise content, thank you!!
Glad you enjoyed it!
Awesome video! Thank you it helped me understand it a lot! One question tho, you don’t need a transmission control if you are using a manual transmission correct. Sorry if it’s a dumb question
You are correct. Trans control is for automatic. Manual you can save some cash and get the X
Here a year late but this video is awesome. Thanks for making it
I got the question a lot so I made the video for the new guys. No worries man. Hope you get it installed and running good!
Good info
Thank you
Very informative video man. I am thinking about going this direction with my stroker LS pretty soon. How was the tuning process? I have experience with megasquirt but that's about it.
Its gotta be similar I would imagine. You just control spark and fuel. Im still learning but if I can do it your good!
The switch over was 05 sometime. I have a kinda odd one as far as LS. 05 LQ4. It has 24x and all the gen3 stuff but has the gen4 bottom end. Google shows overlap on gen 3 up to 2007.
I have a DBW Terminator X max not the trans control model. I'm running a T56 Tremec. I have heard that all the Max ecus are the same just the harness is different. My question is can I get the VSS signal from my T56 and use it to have data for vehicle speed on my dash? I know I might have to buy a harness but I'm wondering if the ecu is the same between the Term x max dbw vs trans control of that makes any sense.
Damn you made this like 2+2🔥🔥🔥🔥
Hope it helps. If you have any questions please let me know!
Damn dude thanks its not easy learning all this information while trying to do my first build
You'll get the hang of it. Main thing is have a realistic goal for yourself and work towards it. Lots of info out here so if you take your time you can find answers to most things.
good stuff mate , if you got nuthing to do how about a video on how to down load say 1 of sloppys base tunes and add it to your laptop then your car im not that far from doing that bit myself and never done it before
In the Holley software they have a folder labeled global files. These are your tune files. So you just drag one of his tunes and drop it in this folder and bam! Pretty simple so no video required. If you get lost send me a DM on Instagram and ill walk you through it.

Great video, Im leaning towards a Terminator x Max for my 6.0 LY6 / 4L80e.
To confirm, if I went this route, it will replace all the wiring for the engine and transmission? I wont need to buy anything else?
It comes with a harness for the motor and a max comes with a trans harness. You may need a few sensors depending on your build and you'll need to get an alternator excite wire.
Thanks
🙌
Couple of questions. I know there's a few options of throttle bodies I believe they run different connectors, the map sensors are also different from truck to car intake connectors and you did touch on the alternator. Different options available there for connection. Are these variations addressed from Holley? Thanks
I have a drive by cable TB so i cant answer your drive by wire connection problem. I would imagine a stock GM TB would work form like a tuck but do your research. The Alt is wired with the kit from holley and it goes to 12v keyed power and its done. The power pole on the alt goes to battery. The map sensor I use is for a standard truck style map but if you get the other style GM map you can just swap the plug out or adapt it. Check my guys at WARR performance for any adapters or problem solving stuff. Also Sloppy has a website and sells plug and play alt harness/ e85 sensor combo and they are slick. Have one on my Twinnebago.
Damn good video
Thank you!
Thank you for the video. Why do you say feelin froggy with the 700r4 trans? No good?
Depending on your power level they are not really known for being a good platform from what I understand. 4l80e is the go to for overdrive and reliability
What if you have a 05 ls2? 24x crank and a 1 x cam on the timing cover. Also knock sensor on the side lol
What engine wire harness do you have? 24x or 52x
I wish the prices were still the same in May 2024 as they were when this video was made......
Yes me too. It’s still a good value for the money but they are not today. If you can find a used one that works that may be an option.
@BurnDown I'll looking at this, the max. I have a complete L96 gen 4, with Trans and transfer case. All together was a rolled truck. But I'm swapping in for a older c10. Would the max control the Trans with transfer case?
It will control a 4l80e and with an add on it will control a 6l80 but not sure about the transfer case sorry.
Incredible info bro !!
I do have a question though.
I'm thinking about purchasing the lsx 454 create engine and Holley specifies that the terminator x are for the 4.8, 5.3 and the 6.0 displacement engines. Does this matter when choosing an efi system whether I go with Holley or not? Or is it irrelevant as long as the correct crank sensor (28x, 58x) and fuel injection plugs (ev1, ev6 etc) are chosen.
You can tell the software what size the motor is and it will adjust the tune for your displacement. You will need to pick what injector plug you plan on using. As for the reluctor wheel its same thing you just choose what it is but you will need the correct harness for either one so pick the system that matches what you are trying to do as far as 24x or 58x
i have an LS with a 4x cam gear and a 24x crank from another engine ..can i change the end on the harness for the crank sensor .when i bought the terminator max x from holley they said i needed the 58x harness so it would fit the locations of the other sensors but i have a 24x crank sensor .so my question is can i just change the plug end and use the harness as is and set up the computer with a 24x crank and a 4x cam . thanks
I dont have the answer to this yet but im actually doing the same thing. I had a 24X motor and im building a 58x so ill post the answer as soon as I get that far. Meantime you can ask on the Holley forrum of Face Book or the Sloppy Mechanics Public page on FB as well. Lots of smart guys and even more smart asses so dont take anything to heart.
Good info,I'm no good with computers, so hp tuners is not happening for me which means I have to pay someone to flash my pcm then I have to pay for a dyno tune,am I wrong in thinking this terminater x will be good for me to tune my motor all my self,or is there more to it,this is my first LS and to figure what direction to go.
They have a wizard setting that will get you up and running. After that you can download a tune from the tune cabinet on the sloppy mechanics Wikipedia page and use it as a refine for your timing table if need be. At this point it m sure you can get a tune that will be close for your set up. I would recommend using a terminator for your first build.
I have a question, sorry if this sounds ignorant, but me and a buddy of mine bought a drift 240sx shell and we are throwing a 5.3 in it. 24x reluctor wheel. We are gonna use a t56 trans, and maybe boost it down the road. Will we need the max or just the X?
The X will work for that application
Question if I’m going to delete the knock sensors on my Gen 3 5.3 will I need to find a specific terminator kit or just leave the connector not plugged in?
You dont need to plug them in. Form what I understand holley knock sensor software is crap anyway.
I have a 2002 6.0 going turbo in my el Camino I have upgraded hpi 1250cc injectors but they look exactly like the truck style so the multec should work for me right?
Yes
Hey will this work if your going carbureted? This helped telling me I have a 24x and need the max. Now I just need help with that
You buy this so you dont have to go carbureted. It will run the fuel injection on the LS motor.
Ok so if I'm going to try a 6.0 with a cam in my 87 trans am with a 700r4.. if I go with the one that runs the throttle body and trans for 4l60 can I turn that off until I do my upgrades?
Yes just get the XMax and you have all the options is you can afford the extra cost.
Hey man can you use a cable throttle body with the xmax, I want to use a 4l80e
YEs
Does this harness have plug to donor gas pedal or is there a aftermarket harness for that to work?
The X max can do drive by wire but its an add on.
Working on a LS swap on a 300zx, can I use the Holley Terminator X even tho I’m using the stock 300zx manual transmission??
Yeah. You just need the terminator x to control the motor. If you want a drive by wire option tho you will need the xmax. So plan your build before you buy your holley
Do I need to buy the little hand held screen if I'm gonna buy the 7 inch digital dash, or the 7 inch dash can do what the little hand held can
You need the little dash to run the wizard in the very beginning to get started if you dont have a laptop. It will also datalog and the 7" will not on the terminator X i dont think. Its only 100$ more for the screen.
If I have a th350 and plan on 4l80e in the future can I buy the x max now and run my th350 until I swap for 4l80e?
You sure can. The transmission harness is a separate deal form the harness that runs the motor. You can save the harness and just add it later on if you swap the transmission later.
Would one of these Holly's work on a 93 LT1 with 24x conversion EFI connection coil on plug with LS1 computer
They make a universal one but you would be on your own to make it work.
Am using a 2001 Chevy Silverado 5.3 4l60e combo for my swap what kit can work for me also injectors
Follow the instructions in the video and you'll know what to buy. You will need an X max to control the 4l60e. The injector harness will depend on what injectors your using and the plugs they have on them. Also if you want to drive by wire that is also an add on so make sure you decide what you want and get the right package for your application.
If I got the terminator x max ls1 24x (550-919) am I restricted ls1 motors or am I able to go any 5.3 4.8 6.0 with the system ? Got it for a steal on market place lol thanks in advance haven’t gotten a clear answer
All the truck motors are considered LS1 so your good to go. Since its a 24x you'll need a motor with the knock sensors on top of the Valley cover to have the right reluctor wheel for the computer you have.
Will terminator x max efi plug and run with the sniper intake manifold and sniper throttle body on ls motor?
If your talking about a sheet metal intake yes. Throttle body will depend on if you are drive by wire or cable but yeah the manifold doesn’t matter and you can get the correct throttle body for your application that will bolt to that manifold.
I currently have a th400… will it run fine with the XMAX? I wanna get the xmax because im thinking of going 4l80e in the future!!
Yes you just wont need the transmission control with the TH400 but you will have it if you ever upgrade.
Which do u prefer dbw or cable they told me with dbw it’s only certain throttle body’s that can be used
So both my cars are Cable with WARR throttle bodies to keep it simple for what im doing. I though about wire for the Twinnebago but it was set up for a carborated application so it has a cable pull already installed so ill just make it pull on the TB. I know they have some info on Sloppy Mechanics about what pedals will work. I think Holley sells one as well separately. If your buying the X Max its an option and its up to you and what you want.
-Dane
Thanks for the information bro
I have an original 2004 Suburban 5.3 and trans nothing but stock maybe update injectors later for eventual turbo. Terminator X Max???
you need an X max to control the transmission. So yes you car correct.
What about the “power tap” how is that wired in? Or is that already in the harness?
Power tap for? Like sensor 5v and 12v output? They have a plug you can wire into for that.
👐
Whats up FUn Fun
How do I run the Holly Terminator x on a jeep 4.0 , I have the hyper spark distributor , can the computer run soly off that ?
Im an LS guy so sorry I don't have an answer for you.
Which gas pedal to use for the drive by wire set up? Ls1 Ls3 throttle body. Thanks in advance
Never mind I followed your instructions and found it. Gm part #10379038. Thanks.
I have bit done the drive by wire so I couldn’t tell you. Check the Sloppy Mechanics Wikipedia page. I think Matt tried a bunch of pedals from the junkyard and found a few that were compatible. You could also call Holley or try the Facebook page they have.
If I pick up the x-max with the truck style injectors and later decide to say change to the ev style injector, what do I need to do? Buy another harness from Holley? Also with the x-max if later I decide to run a manual or no overdrive trans just tune it out. Is that possible?
You can just buy the injector harness. They range from 115-140 bucks.
What Kyle said. Or you can cut the ends off and put new plugs on the harness to match your new injectors but that kinda defeats the purpose of plug and play.
AMAZON HAS ADAPTER FROM THE TRUCK INJETORS TO DEKA 80 FOR ABOUT $29..00 DOLLARS
So for my truck, I’m building a ford small block but I wanna put Holley efi on it, I’m using a 5 speed manual so I should be fine with terminator x?
Depending on your set up I believe they make EFI kits for ford. The Terminator X would not control a transmission so yes if they make a kit for your motor the X would do the trick I believe.
@@Burndown they do make a kit for pushrod fords and imma run a manual so I don’t need trans control
I have a th400 transmission, would this work or will I have to do something different on my ls swap
You can run a terminator x with a TH400
Just wondering why you said. If you really want to play with fire with the 4l60e
If you make power it will die.
I have multech injectors but eventually want to go turbo would upgrade to ev1. Can I run multek injectors now and swap to ev1 or would I have to buy a new ECU I'm not trying to buy new injectors right now.
They make adapter harnesses for the injectors or you can just wire up new injector connectors when you make the change
Can you run a throttle by cable using the x max and an electronic transmission
Yes you can do by wire or cable with the xmax
What injecters,fuel pump and fuel pressure regulator do run in maliboom thanks
It has changed a bunch but right now im on a Magnafuel 4303 pump Fuel lab regulator and some snake eater 1000 cc injectors.
Can I still run the Terminator Max if I have a non electric trans going to switch to a 4l80e later?
Yes you can. That way with will have flexibility later if you do upgrade
If I buy the one with trans control can I still use a turbo 350 or 400
Yes
This video for only LS engine owners
Yes. I made it before Holley came out with the other computers that control other platforms. Sorry for any confusion.
What would be a good one for 98 Pontiac WS6 LS1 engine 5.7 and yes it is an original trans am engine that came with the car in '98
Depends on the transmission and if its a race car or not. This computer won't run your dash or anything like the stock ECU will. If its a race car you will need one for a 24x and then select the correct injector harness. You will need an Xmax if you have the 4l60 auto trans in the car. If its stick a standard Terminator X will work.
@@Burndown it has the 4l60 I wanted to have the race car and a daily if possible but just was wondering cuz I didn't know what would be a good program for my car or you have any suggestions on one I can use for fuel economy and drag race I like to do both
can I add on 4l80e to my terminator x I wanted th400 at the time when I bought it
If you have the X max yes if you just go the terminator X then unfortunately no.
If I'm building a lsx 427 and will be running a t56 which terminator x would I need to use?
Just a terminator x unless you would like to do drive by wire
How would you do your cruise control if you have drive by wire
I have not set that up so ask on the Holley forum on Face Book and see if they have the answer. Sorry I dont know man.
So when you order the terminator x it does come with the harness or you have to order it separate?
It comes with it. You can also order options on the Xmax for transmission control and drive by wire. They are both add ons and will make the price go up tho. Just depends on what you need and want.
@@Burndown thank u and im using nv3500 manual trans and cable throttle
Im having a hard time finding a x max that can be used on a late modle post 2009 4l80e. Holly doesn't not it but summet and jegs says it cant be used on that transmission.
X max has add one you would need to control direct injection and a 6 speed
I haven’t played with any of that as it’s above my pay grade 🤣
so just to clarify, if i am using i 5.3 engine with ev6 injectors i would order the terminator that they designate as the "ls1/ls6" version?
Yes and the only other thing is if is a gen4 motor or a gen 3 motor. Cam sensor will be on the front if it’s gen 4 and on the top in the back by the oil pressure sensor if it’s gen 3. Gen 3 is a 24x and a gen 4 is a 58x
@@Burndown awsome. thanks man, thats great news. great video. youve earned yourself a new subscriber
@@morganclawson9985 Awesome thank you!
Can holly run a ls4 with a 4T65E
Or am I stuck with a manual valve body? Thanks
That is a good question. Thats the FWD LS no?
I have a gen 4 out of a 09 ss Impala that I'm trying to put into a S10 which one do I need
Should be a 58x gen 4 motor. Not sure on the injector plug on that car tho. I would look at the Holley diagram for injector plug ID and pick the correct ones. Look at the ev6 style and see if that's it or not.
Thanks for that bit of knowledge. I've taken the motor out and put it into a short bed Chevy truck . 58x would that change if I'm swapping
This guy looks like the amount of tired I hope I am someday when my garage is full of kickass cars and engines 😁🤘
I forgot what actual sleep was like man. I do know what I think are back yard built cool car tho 😁 Im working on that now.
So if I have a bone stock 5.3 with a t56 I should get the TERMINATOR X 24X/1X MULTEC 2 LS MPFI KIT correct?
if your using the stock truck injectors yes sir!
@@Burndown thank for the reply! Great video i appreciate it.
@@Gabe_Z31 You got it!
I just built an l92 with a 4" stroke I ordered my crank with a 24tooth reluctor but my camshaft sensor is on the front cover I cannot find this provision in Holley's web site
24 tooth reluctor wheel motors are gen 3 and have the cam sensor in the block on top in the back generally. Go to Warr performance and get a cam sensor extension and you can just plug it in and run that to the front of the motor
@@Burndown thank you. I was going to use my ecm from my lq4 that currently is in my elco but I am running boost on the 6.2 so holley terminator x is my next choice
@@Burndown bro I swear to god think you so much Jesus 😭😭😭🐐🐐🐐🐐
Will Treminator X work with manual trans and dbw ?
YES for cable TB no for DBW
Can i keep my ac compressor working with this ecm ?
Yes it will run an AC compressor.
Will the transmission controller control a 4l65e
Yes a 65 is the same as a 60. It just has a few parts that are a bit better inside it but its pretty much a 60.
Does the Terminator use the knock sensors?
It has provisions but no one uses them or at least I dont.
I wanna run a 6l80 will I be able to with any terminator?
I dont believe so. I think it will only do the 4 speed transmissions like a 4l60e and a 4l80e but I could be wrong. You can check on the Holley website. Im sure they are working on a controller or software for that transmission if they dont have something already.
will the x max also work with 6l90 trans?
No I dont think so. Im sure they are working on it tho.
Can you use ev6 injectors with it?
Yes you just need to but the one with the correct harness and they need to be High Impedance injectors for the Terminator X to run them! If they came in a GM platform your good.
What one will work on a T-56?
A regular X. The X Max has the transmission control
So its not just the ecm? Its also harness?
It has everything you need to run the motor and control the trans depending on witch one you get. It also comes with a small touch screen you use to set it all up.
Can you run drive by cable with the max?
Yes you have the option of drive by wire or cable with the XMax
You need to order that as an option tho
I have a 6.2 with a 4L80 throttle cable which terminator is best
You will need the X Max to run a transmission
@@Burndown so a 5.3 with a 4l60 is the max way to go when running drive by cable TB going in a 1963 impala?
@@frankyfrank6387 yes you need a max to control the transmission as if right now. It will also do drive by wire or cable.
@@Burndown thx for the reply
What one do I need if I wanna run a t56 transmission do I need the terminator x ecu our the terminator x max ecu
X
@@Burndown so just the basic terminator x ecu
@@dojliferp8612 yes. You will need the one that matches your reluctor wheel 24 or 58 and the right injector harness. If you go in Holley website and look up the terminator x that have a section that talks about how to choose the right one.
@@Burndown ok thanks a lot
Which one to run if I'm using a t56 transmission
The Terminator X will work for you since you dont need the transmission control. If you want to run the T56 and a drive by wire you would still need the X manx to make that happen.
@@Burndown thanks so much
@@bjigga225 You got it!
how do you get one minds been on order for 8 months
Order form a supplier not directly from Holley. They will feed the suppliers before the sell to the public from what I understand.
@@Burndown i did order from a supplier and still waiting for 8 months at this time, as a matter of fact i cancelled and went with Fitech forget holly
where does t56 fall into x or xmax ?
x. Xmax is for trans control and drive by wire.
@@Burndown thank you bro, yea thats what i was thinking.
How in the world do I send file from laptop to ecm engine running like crap 24x truck engine all stock for now but have Holley 3bar
Do you have the canbus to USB cable?
You need the USB cable they sell to talk to the ECU directly. If you dont have one you could always run the sed up wizard again and choose the 2.5 or 3 bar map (I forget what the choices are but I want to say I started and ran my car on the 2.5) that will get you closer to what you need if the map is your issue. You running on the internal map right now? Its a 1 bar.
Whats up man!
Yes have the USB cable
@@pimpinak89 The recycle looking button up top will sync the open global file with the ECU.
List the sources you are referring to in your videos. Thanks
What sources?
What injectors would you recommend for a 5.3 with a BTR stg4 truck cam I may eventually do a small nos kit
I would go with a smaller cam unless you want to rev to the moon and make less power down low. If your only doing a cam and springs I would say some 36-42# injectors would work fine and you would have a little room to run E85 as well at some point with a little larger injector.
why do car guys wear their hats like this
The weakest men always talk bad about others
So which one do I need for my 5.3 4l60e
You will need an XMax that matches your reluctor wheel and the correct fuel injector plugs
@@Burndown thanks man
I purchased an Holley x max 550-917 for my truck build but I just got my dad’s racer after he passed in 2003 so I was wondering do I need to get an different ecu cause the race car has a power glide an I don’t feel like doing the return process can I just run this one without hooking up the transmission control?
Yes you just run it without transmission control. You’ll need the correct injector harness still and a 24 or 58 x reluctor wheel for your motor.
