Not sure it'll make your car run better UNLESS there is something wrong with your factory fuel injection system. The beauty of the Terminator X is dealing with NON-STOCK engine changes like camshaft, nitrous, supercharger, heads, bigger injectors, etc is much easier with the Terminator X. Nobody really does chips anymore.
@@Mustang-Geek I have ordered the kit from Summit racing today. I have a 347 stroker that the fuel injection on the car has always struggled with. Wish me luck - DIY!
Man I really want one of these setups for my 1988...if only to get rid of some of the rats nest of wiring in the engine bay. Your install video made it seem slightly less intimidating but I’m still not completely confident I could install it on my own. 😭😬
One thing Holley don't mention is that the handheld sets the IAC as a gm stepper in the setup. You need to go on a laptop and change it to ford 5.0 pwn and assign it to output #4 for the IAC to work right.
@@inerceptor Not sure. At the very least, you can save the file to the SD card in the handheld, open the file on a computer with the free Holley software, make the change, and then reload it using the handheld.
Great Video!! Any chance you kept the EVAP Charcoal Canister system with the solenoid connected to the car? Did you wire it through an input/output on the terminator x system?
Huge thanks for the detail in this video!! I just took the last three days to install this kit and got it fired up today thanks to you and your video! Working out the bugs now... Thanks again!
FixBody Mustangs I pulled the car out of the garage today for the first time in two years! I spent some time trying to go through the menus and I did figure out how to get the IAC to work. It’s as you say, sometimes 2% then after a quick throttle blip, says 40%. Also, I sent you a Dm yesterday. Thanks again!
Great videos! I noticed that you mustang appears to be largely stock. How much difference in setup would there be in a car like yours and say one with a good amount of bolt ons? My mustang has a stock cam and short block, but has had everything else replaced with something "better", including a turbo. For reference my car put down 400/460 at the wheels.
Hello great video of explaining the holley but during the video I noticed your air bag light is flashing. I had the same problem the air bag module behind radio is probably shot. I taken mine apart and found leaking capacitors and the fuse was blown. All due to age mine was a 91 foxbody also.
@@gregbrzostko7930 Interesting. My fuse tested good, however. There is continuity across it. The module works, it just doesn't seem to think all the circuits are OK, which they are.
@@Mustang-Geek Ok mine tested bad, when I unwrapped it you could see that it was bad. My guess was the capacitors leaked and blew the fuse. Thank god they didnt leak and pop the air bag...
Do you just remove and leave out one of the narrow band O2 sensors and install the wide band? If so, which side did you install yours? Appreciate the videos!
The gauges, yes. My air conditioning doesn't work, but I'd have to figure that out. If you want me to do a video about that, let me know in the comments!
@@Mustang-Geek yes do a video about the stock gauges...and do you plan on leaving the handheld device like you have it or mounting it because I to have this system on my '91 Notchback and I really want to leave it as a handheld so I can easily make adjustments when needed
@@wood4278 Info on the gauges is in this video. ua-cam.com/video/ld2yUFY_dp0/v-deo.html. Here is also a wiring digram: www.holley.com/blog/post/how_to_install_a_holley_terminator_x_efi_system_on_a_foxbody_mustang/
Will you be sharing in a new video your overall review (pros-cons) about the teminatorx? Basically what you found that was better with T-x vs the factory ecu. That video would be very helpful, I’m thinking of getting one only for my supercharged fox.
Great idea! For a supercharged car, it's a no-brainer because you can change pullyey, injector, etc, without too much tuning trouble. Also being able to control timing without any add-on boxes is a huge plus.
Stupid question, but if I were to install a Holley EFI, could I still run a GT40 intake? I have an original tubular intake that I love and don't want to replace, but I need a new EFI because every shop I have nearby has refused to dyno-tune my A9L 😞
Great videos, much appreciated but could you clear a couple things up for me if you wouldn’t mind.1st- I’ve got my battery in the hatch, using an inline fuel pump. I just switched from megasquirt. Have a stand-alone relay for my fuel pump in the hatch using the switches power wire from the stock FP relay under the seat. Where should I hook the green wire from the terminator? Connect to dark green/yellow wire on relay or could I connect it to the 8 pin green connector by kick panel? 2nd- I don’t have the stock harness anymore can I just splice switched 12v from the ignition switch RED/LIGHT GREEN wire for the ECU and the +coil? Or do they need to be separate? Thank you in advanced
I saved that diagram last night, thank you. So I can just connect both the coil and 12v switch together and them on ignition switch or keep them separate?
A couple things 1) Regarding the fuel relay under the seat: are you USING the relay under the seat to provide power to your relay in the trunk, or are you BYPASSING the relay under the seat to provide power to your relay in the trunk? 2) Regardless, the green wire from the Holley harness has 12V+ power when the Terminator wants the pump to run. So, you could connect the green wire to the green wire under the seat OR connect it to the red wire at connector 216 like the video and the schematic above. NOTE: not sure what year your car is, but connector 216 on mine is grey (and has the air bag sensors on it as well). Leave your other relay in place or bypass it, it won't matter. Keep in mind that if you leave your other relay in place, you'll have two relays powering the fuel pump, so if there's ever a problem, you'll have to check BOTH relays. 3) The 12V+ switched on my car does not need to be separate. See schematic above. My wires were literally spliced together from the factory, and it works great.
So besides the tuning capabilities, how else is it beneficial? Does the engine run better/more efficiently? Has your mpg improved? (not that thats a big concern in a fox lol)
Thanks for the video. I'm considering one of these instead of paying for a dyno tune because I ultimately have plans on more changes. Currently running a V2SI at 12psi max boost and a GT40X Ford racing crate motor. I put the car away in 2012 and it seemed to be lacking power from what I remembered so I put a new fuel system and blower on the car. It runs good but the low end just doesn't seem as it should. All compression readings check out. I suspect computer or tuning is needed. Ultimately I'm going 363 W/AFR 205 heads and the same Vortech blower so I'm not interested in spending money on a tune for this current combination. How was the tech support on this product? I am a former ASE technician and good with electrical but lack any tuning knowledge so that is my worry. Located in CT if any other fox people have suggestions.
Tech service from Holley is pretty typical: make sure you follow their instructions, otherwise they're going to tell you to install it exactly as instructed first. Take your time with the wring and double-check everything before starting the car and you'll be fine. There really isn't much "tuning" required. Just messing with the settings a little to make it run the way you want.
@@Mustang-Geek you can get it running well with just the handheld but it will never come close to the fine tuning the map and multitude of other settings with a laptop.
ABSOLUTELY. That's exactly what this system is for. This system can accommodate modifications easily without "chips." Just make sure you select the "street strip" camshaft option in the setup wizard.
@@sneakingfox5887 YES! This is EXACTLY where the Terminator X is awesome. You only need to install a 2-bar MAP sensor (for up to 14 PSI) on the existing harness, and then connect to the Terminator X with a laptop to have it ignore the internal sensor. (I don't think the handheld has a menu for changing the MAP sensor input.)
@Mustang-Geek on throttle depending on load, it's anywhere between 12.5-14.7. Once I get off the throttle to coast it goes up to 18:1. Single turbo 5.3, first drive with terminator x today. I'm not familiar with what you are mentioning
I bought a 93 gt in January. It has a 363 Dart short block, trick flow 170's, typhoon intake, msd 6AL, I think an e-cam, and a 76mm Precision turbo. I think the kit is On3 though. I drove it 4 times around the block before I registered it and it ran so strong. While waiting to register it, I noticed the valve covers were leaking. I took upper intake off and replaced the gaskets and bought new valve covers. After I buttoned everything back up the car has never ran the same again. Not even close. So I replaced intake with a carb style edelbrock intake with elbow, installed 340 stealth fuel pump in tank, installed edelbrock fuel rails, aeromotive regulator, and replaced all fuel lines to 3/8. The car still runs like crap. Will the terminator x fix the car?
Woah. That's a tall order. Not sure what's wrong with your car, BUT the Terminator will work with the turbo. Did your new valve covers not have breathers?
If you set your timing at 15 degrees then why did it say ignition timing was at 12 degrees when idling? Also what’s the difference of ignition reference angle which Holley has it set at 10 degrees and the cranking timing which Holley has that set at 15 degrees?
Good questions. The 12 degrees you see is what the terminator X's ignition map is using at idle. It also varies ignition timing to stabilize idle. In order to "synchronize" the distributor to the terminator X, I *chose* to run the car with 15 degrees of timing. The timing does NOT change in that mode. Then, I used a timing light so the *actual* ignition timing matched 15 degrees. That way, the Terminator X knows when it is commanding 12 degrees (or whatever value it wants), that's exactly what the engine is actually seeing. Does that make sense?
Would u recommend this for an 84 Capri 5.0? Had a little engine bay fire and was considering the sniper efi system, then I saw this product. I would be running an external fuel pump and mostly stock 5.0 EFI related components. Thanks for any advise!
The sniper is nice because you can retain your carbureted air cleaner, intake, and there's less wiring involved. In fact, I'd recommend this system because the PCM is located on the side of the throttle body instead of the front where the Ford distributor can create a noise problem: www.holley.com/products/fuel_systems/fuel_injection/sniper_efi/sniper_efi_stealth_4150/sniper_efi_stealth_4150/parts/550-872
If it's already carbureted, there are better options like the Holley Sniper EFI Stealth: www.holley.com/products/fuel_systems/fuel_injection/sniper_efi/sniper_efi_stealth_4150/
@@Mustang-Geek yeah I was looking at those. You think that would be the best route for me? I’m planning to keep it NA and nothing special, just well built and efficient 👍🏼 my F150 is a single cab shortbed with 33s so it doesn’t need too much to move it haha
Hi, are you using the Fox Body specific Terminator X kit that uses the ford sensors & IAC or the universal ford kit that uses GM sensors? I’m about to pull the trigger on the Terminator X kit for my stock 5.0 and the original Fox Body specific kit is now discontinued… I’m wondering how well the kit with GM sensors and IAC actually work… Yours seems like it runs really well…
The kit I used is no longer available, but I'd get whatever kit uses the Ford sensors. The Ford IAC works well if you do this: ua-cam.com/video/F2APprj4jeU/v-deo.htmlsi=pukVZ36QP6r0fa11
This is for the Fox Mustang kit, but it could apply to others. No I didn't feel a bump in power, but that's expected. This is a stock 1991 Mustang GT. However, I'm getting ready to add nitrous and maybe a blower, so the Terminator X will come in handy.
I got it running . For some reason I can’t use my factory rpm gauge every time I hook it up it stops getting spark. I’m just going to end up getting the dash and the bigger screen from holly
@@jacobwilkerson6244 Seriously, though. Check that wiring digram I linked to above. The factory tachometer should work fine. It does on mine if wired as shown.
Your info on static timing is a lil misleading..When you go into the setting on the handheld its only used for verification purposes...When you shut off the key that setting is lost...The way the system is supposed to be setup is by setting the balancer to 10* BTDC then aligning the skinny blade on the reluctor wheel on the TFI distributor with the inductive pickup aligned dead-on or just slightly behind of where the #1sparkplug wire is placed in the rotation on the distributor cap..... If you want 15* as your base for your TFI setup you need to set the balancer to 15* and possibly phase in your rotor too.. Then the distributor gets locked down and then you unplug your fuelpump fuse and pull up the idle table up on the handheld and crank the engine to see of rpm's are being registered...If rpm's are being registered you then put the fuelpump fuse back in then turn key on to open the wizard and pull the static timing checker up. You then can use 15* as a timing reference on the handheld ..You set the 15* number on the handheld and even though the balancer is set to 10* on your application [30* on my application with a 45* pickup reference] when the timing light hits the balancer it will or should read 15*... Also verify timing accuracy at rpm's up to 4000 to see if the mark stays on the money if it waivers you need to adjust the settings in milliseconds to get the curve to jive.. If the mark is off on the 15* mark at idle you adjust distributor then you may need to phase the pickup using an octane rod assortment pack....If you think Im wrong ask a Holley tech.....He will verify but never tell you this outright as in being forthcoming... It took me a few hours of learning through watching Holleys Sniper setup vids to learn how to use the lingo to coax the info out of a Holley tech on how to properly phase in my MSD ProBillet Distributor which utilizes a magnetic pickup that needs to be set with a 45* reference angle..Nowhere in my universal instructions does it remotely state any of this as its bare bones and the money saved is supposed to go to help supporting a fellow tuner is its not as novice friendly as they lead it to believe.The tech says to use a 45-60 degree initial balancer setting for utilizing a magnetic pickup and 50* reference angle for a dual spark distributor....If you dont get the distributor set right youll experience failed injectors or an overheated ECU that will eventually fail like a TFI module does so if you set your distributor to 10* BTDC thats your timing for the TFI system and where your static timing is really set when the 15* is not commanded on the handheld for timing light verification purposes only and not meant to be driven on.....Good Luck
A factory TFI distributor should not need to be phased. The idea is to simply make sure that the timing the Terminator is commanding is reflected in the motor. This is the same as pulling the SPOUT and setting the distributor to 10 degrees...only with the Holley, you can set the "check timing" to any setting you want.
Neither. If your car currently runs well, the system will do nothing for you. I install the system in anticipation of adding a cam, hands, supercharger, etc and not having to mess with chips for tuning.
I’m not familiar with that. If it’s doing what you needed to do, I would not switch. However, the Terminator X is extremely adaptable to both-one and power adders.
@@briangt1013 There is only one Terminator X. If you have a boosted application, you purchase a different MAP sensor, like this one: www.holley.com/products/fuel_systems/fuel_injection/sensors/map_sensors/parts/538-13

So I replaced intake with a carb style edelbrock intake with elbow, installed 340 stealth fuel pump in tank, installed edelbrock fuel rails, aeromotive regulator, and replaced all fuel lines to 3/8. The car still runs like crap. Will the terminator x fix the car?
Woah. That's a tall order. Not sure what's wrong with your car, BUT the Terminator will work with the turbo. Did your new valve covers not have breathers?
@@Mustang-Geek yessir they do and I ran a catch can with 10an hose from each cover.
@@Mustang-Geek it had a typhoon intake on it when I got it but when I replaced valve covers and gasket I replaced intake also.
@@Mustang-Geek can't send a pic??? No option to otherwise I would have
@@adamjolley2128 Still a tough one. Do a leak down test.
thanks for the video! keep them coming!
If you set your timing at 15 degrees then why did it say ignition timing was at 12 degrees when idling? Also what’s the difference of ignition reference angle which Holley has it set at 10 degrees and the cranking timing which Holley has that set at 15 degrees?
Good questions. The 12 degrees you see is what the terminator X's ignition map is using at idle. It also varies ignition timing to stabilize idle. In order to "synchronize" the distributor to the terminator X, I *chose* to run the car with 15 degrees of timing. The timing does NOT change in that mode. Then, I used a timing light so the *actual* ignition timing matched 15 degrees. That way, the Terminator X knows when it is commanding 12 degrees (or whatever value it wants), that's exactly what the engine is actually seeing. Does that make sense?
Would u recommend this for an 84 Capri 5.0? Had a little engine bay fire and was considering the sniper efi system, then I saw this product. I would be running an external fuel pump and mostly stock 5.0 EFI related components. Thanks for any advise!
The sniper is nice because you can retain your carbureted air cleaner, intake, and there's less wiring involved. In fact, I'd recommend this system because the PCM is located on the side of the throttle body instead of the front where the Ford distributor can create a noise problem: www.holley.com/products/fuel_systems/fuel_injection/sniper_efi/sniper_efi_stealth_4150/sniper_efi_stealth_4150/parts/550-872
On your acceleration enrichment how much percentage did you drop it? Or did you drop it point by point?
I honestly don't remember. Just experiment and see what works for you!
@@Mustang-Geek im new to the whole tuneing world so it makes me nervous haha
I have a 351w in my ‘77 F150 and I’m thinking about buying something like this
If it's already carbureted, there are better options like the Holley Sniper EFI Stealth: www.holley.com/products/fuel_systems/fuel_injection/sniper_efi/sniper_efi_stealth_4150/
@@Mustang-Geek yeah I was looking at those. You think that would be the best route for me? I’m planning to keep it NA and nothing special, just well built and efficient 👍🏼 my F150 is a single cab shortbed with 33s so it doesn’t need too much to move it haha
@@pnwchris2000 Yes, the Holley Sniper EFI Stealth is perfect.
Hi, are you using the Fox Body specific Terminator X kit that uses the ford sensors & IAC or the universal ford kit that uses GM sensors?
I’m about to pull the trigger on the Terminator X kit for my stock 5.0 and the original Fox Body specific kit is now discontinued…
I’m wondering how well the kit with GM sensors and IAC actually work…
Yours seems like it runs really well…
The kit I used is no longer available, but I'd get whatever kit uses the Ford sensors. The Ford IAC works well if you do this: ua-cam.com/video/F2APprj4jeU/v-deo.htmlsi=pukVZ36QP6r0fa11
Thanks! I just sub’d. I’ll go check out all of your foxbody content. Thank you
@@AJsSpeedShop Excellent! Thanks!
Hi, great video. Is this the fox mustang specific setup or universal Ford setup? Also, did you feel a bump in power using this system? Thanks!!!
This is for the Fox Mustang kit, but it could apply to others. No I didn't feel a bump in power, but that's expected. This is a stock 1991 Mustang GT. However, I'm getting ready to add nitrous and maybe a blower, so the Terminator X will come in handy.
Really appreciate the video! I'm really curious if this system will work on my 1995 F150 with a very custom engine build.
It’s the same thing just a bigger intake. Literally same motor. You can use this kit on 289 302 and 351w efi enginee
I finally got my terminator x kit installed and I’m not getting any spark from the coil anyway you could help me out?
Check your wiring. Here's a diagram: www.dropbox.com/s/p8e4hsq9ohuqbhy/014-holley-terminator-x-foxbody-mustang-install.jpg?dl=0
I got it running . For some reason I can’t use my factory rpm gauge every time I hook it up it stops getting spark. I’m just going to end up getting the dash and the bigger screen from holly
@@jacobwilkerson6244 Seriously, though. Check that wiring digram I linked to above. The factory tachometer should work fine. It does on mine if wired as shown.
Your info on static timing is a lil misleading..When you go into the setting on the handheld its only used for verification purposes...When you shut off the key that setting is lost...The way the system is supposed to be setup is by setting the balancer to 10* BTDC then aligning the skinny blade on the reluctor wheel on the TFI distributor with the inductive pickup aligned dead-on or just slightly behind of where the #1sparkplug wire is placed in the rotation on the distributor cap..... If you want 15* as your base for your TFI setup you need to set the balancer to 15* and possibly phase in your rotor too..
Then the distributor gets locked down and then you unplug your fuelpump fuse and pull up the idle table up on the handheld and crank the engine to see of rpm's are being registered...If rpm's are being registered you then put the fuelpump fuse back in then turn key on to open the wizard and pull the static timing checker up. You then can use 15* as a timing reference on the handheld ..You set the 15* number on the handheld and even though the balancer is set to 10* on your application [30* on my application with a 45* pickup reference] when the timing light hits the balancer it will or should read 15*... Also verify timing accuracy at rpm's up to 4000 to see if the mark stays on the money if it waivers you need to adjust the settings in milliseconds to get the curve to jive.. If the mark is off on the 15* mark at idle you adjust distributor then you may need to phase the pickup using an octane rod assortment pack....If you think Im wrong ask a Holley tech.....He will verify but never tell you this outright as in being forthcoming...
It took me a few hours of learning through watching Holleys Sniper setup vids to learn how to use the lingo to coax the info out of a Holley tech on how to properly phase in my MSD ProBillet Distributor which utilizes a magnetic pickup that needs to be set with a 45* reference angle..Nowhere in my universal instructions does it remotely state any of this as its bare bones and the money saved is supposed to go to help supporting a fellow tuner is its not as novice friendly as they lead it to believe.The tech says to use a 45-60 degree initial balancer setting for utilizing a magnetic pickup and 50* reference angle for a dual spark distributor....If you dont get the distributor set right youll experience failed injectors or an overheated ECU that will eventually fail like a TFI module does so if you set your distributor to 10* BTDC thats your timing for the TFI system and where your static timing is really set when the 15* is not commanded on the handheld for timing light verification purposes only and not meant to be driven on.....Good Luck
A factory TFI distributor should not need to be phased. The idea is to simply make sure that the timing the Terminator is commanding is reflected in the motor. This is the same as pulling the SPOUT and setting the distributor to 10 degrees...only with the Holley, you can set the "check timing" to any setting you want.
How do I get my iac down from 93%
Find out why it's at 93%, then fix it? I'll need more information about what the engine is doing. Is it idling high?
I have a stock 89 GT, just cut off my cats, will this system give me more power or just make it easier to drive ?
Neither. If your car currently runs well, the system will do nothing for you. I install the system in anticipation of adding a cam, hands, supercharger, etc and not having to mess with chips for tuning.
Best thing to do is a set of gears and a short throw shifter, exhaust.
I have the pimpxs ecu .. should i switch or save my momey
I’m not familiar with that. If it’s doing what you needed to do, I would not switch. However, the Terminator X is extremely adaptable to both-one and power adders.
Which is the one for boosted applications
@@briangt1013 There is only one Terminator X. If you have a boosted application, you purchase a different MAP sensor, like this one: www.holley.com/products/fuel_systems/fuel_injection/sensors/map_sensors/parts/538-13
Great detail thanks
Glad it helped!
Very cool thanks for the video.
No problem 👍
Good Job I enjoyed the video

I really want to ditch the 30 year old junk in my Fox for this....
I'm doin it man, no more. My injection works great one month and the weather changes and the car will barely idle. I'm done. Ordering the kit this weekend.
Oooo man you did cover that iam sorry fixbody iam an ediot brother sorry, that’s right you did cover that I didn’t catch it sorry
No problem, no need to apologize. Sometimes videos are hard to find.
