Terminator X Tuning - Disable Key-On Fan Operation
HTML-код
- Опубликовано: 4 авг 2022
- A common complaint we see with Holley Terminator X users is in regard to the fan control. Holley's Basic I/O is setup with some basic operations for controlling 1 or 2 electric fans, with or without A/C. And while these fans are temperature activated, there is nothing in this Basic I/O that prevents the fans from kicking on as soon as you apply key on power to the car, even if the engine is off. In some cases, this can contribute to difficult hot starts and low battery voltage. Follow these easy steps to disable the basic I/O for fans, and use custom output(s) with triggers instead.

I've watched a lot of videos on Holley stuff, and hands down, you present the info in the best way I've experienced. Extremely clear and STRAIGHT to the point. VERY much appreciated!
More people need to do this. Any car we work on, we move to this setup.
Thanks brother super simple easy video to follow idk why I couldn't think about this but I just changed everything around now also added a prevision for speed myself so fans kick off at 35mph instead of causing turbulence and slowing the air
Very useful video, will be implementing this asap, thank you!
Great video Matt! I'll definitely be looking back at this later this evening.
This helped me out big time, thanks. Now I just need to get my cold IDLE, and drive, it starts but don't like to move for few a minutes.
Thanks Matt! Please follow up with the PWM video and since many of us are using the Contour dual fan, I prefer 2 fans with different temperature settings. I'm currently using the Flex a lite PWM controller and it works well, but will be using the Terminator in the future with separate fan control .
Good vid, thanks for the info. I'll need to do it a little differently since I am in fact using a PWN fan. I'd like the fan to be set at like 80% when AC kick is on.
Awesome video, I've been racking my brain trying to figure this out. Thanks for the videos, and keep up the good work.
Thanks Kenny!
@@LeechMotorsports Now I'm having a problem. When my fan comes on the engine starts surging. Fan goes off it takes about 20 seconds for the engine to return to a smooth idle. Battery drops to 13.4 volts when the fan kicks on but then voltage surges with the idle up and down as well. Any thoughts on what I should look into? I've been trying to get this car drivable since before Christmas to no avail and it's springtime and I need to get it going.
I've had a Holley Dominator since V2 firmware. Why Holley hasn't added a feature for fans off with key on/engine off in the canned software I don't know.
Thanks brother, I got an HP and this worked NP (had a diff step or 2 but whtevr). You're concise and to the point I agree. Love it, keep it up.
Awesome information just what I needed! Thank you
good stuff man! i wish you DID get into PWM fan controls though.
Awesome! Video! Thank you!
Thanks brother that helped me out!!!!!
Good video!!! Thank-you
Awsome video thank you.
Followed your instructions on RUclips had to go back to the initiative and turn the fans on a resume and now they were
This is great! Thanks for such a great explanation. Can you create these custom I/Os for Sniper systems as well? We have only done "tuning" with our handheld, but haven't messed with the computer tuning files yet (looks like we need to start😀. Thanks again for a great video!
Thx, perfect how to👍👍
Thank you !
Great video with a lot of helpful information. Does this method apply if you starting engine with AC on with those settings?
This was great thank you. Do you know how to get the holley 7" dash to display MAP PSI instead of kPA? Seems really annoying to me that I cannot seem to get it displayed in PSI when the ecu is set to display psi.
Thanks alot
thanx ive been on the phone with holley and spal for a week there idiots your worked
Is there a way to stop the fans when the car is moving. At some point they are probably hindering cooling.
Is there a way to have the fan function on the dashboard with this change?
can you show how to set up a pwm fan with a/c.
does this setup work for a single 2 speed fan? i am mostly just concerned about turning off the 1rst speed at 190 but turning on the 2nd speed at say 185. would i simply need to not over lap the settings? example turn off speed 1 at 190 and turn on speed 2 at 191.
i currently run a relay setup that steps through based on 2 temp sensors and want to switch to sniper fan control to avoid alt belt slip/screech at start up.
Another great video - thanks Matt!
After implementing this technique, the 3.5" handheld no longer displays the fan's on/off status. Is there a fix for this?
Thank you!
There is not a fix for that. That’s the trade off. The actual pro dash stuff can be setup to show when they activate. But I don’t think there is a way to make that work on the handheld.
@@LeechMotorsports Understood. Thanks for the quick response.
Looks like this is OBE, there is now and option for engine running only.
V3 has "Engine Running Only" checkboxes. Is this the updated way to keep the fans from running until the engine starts?
I changed my settings by checking the boxes and it does cut the fans until the engine is running
Mine fans kicking on during cranking doesn't really affect starting but I'd very annoying, thanks alot for this! Will the fan on/off Still display on the hand held?
No it will not. That part is annoying for folks that use the handheld. I haven't looked if you can get it to display the output status, if you can then in theory you could display the Output status.
I agree. Pretty sure this will not show up on the handheld status screens.
Hello matt do you still offer remote tuning ?
After this change the fans are working as they should but doesn't show when they are on anymore in the 3.5" screen how do you fix that?
Anyone know the answer?
Do you do remote tuning by chance? I'm installing the Terminator X on my fox and have never messed with Holley software before. Would much rather pay to hire a professional than grenade my motor because I tried to do it myself! Ha!
Can this be done on the HP and dominator platforms?
Yeah it'll be the same
@@TurboV8boi right on, appreciate it!! I was poking around and didn't see where I could create and edit the custom outputs. I'll have to dig a little deeper.
Yup, works great, I had to add the IO config file to it.
@@edwardschipper6648 nice. Yeah i couldn't figure it out for a while. Until you get used to it it doesn't make a lot of sense, at least that's how i felt.
@@TurboV8boi Going to play around with this on my Terminator. Sounds like a good way to go. I like not having to do any "extra" wiring and just do it through the software.
Just get the right amp battery. Boom.
