Thank you for these videos. I install my Holley and then took it to a shop for tuning. When I picked up the car it ran like crap your videos has helped me set up the car so I can drive it. Thanks and keep them coming

Great video I can only imagine the time you've put in playing with all these features

God, google, safari are all watching and listening to us. I just was looking for a terminator x for a new edge build I’m thinking about doing, and today your videos come up when I get home and started watching you tube! Great information! Thanks. New sub!

Thanks for making this vid, gonna help when i get my motor running and have to adjust my terminator!!

Eventually thisnis the way I want to go and this video is very helpful knowing I have 5 speed cars this definitely will help me out . Thank you so much. Glad I found your Chanel.

I changed from Megasquirt to TX today 1 start of engine ..changed some of the tune thats really of for the Mustangs . timing and fuel..after setting the timing correctly and engine at temp ... Idle is solid as a rock.. just changed the Iac to 5.0 PWM ...

I had a factory ford IAC on my mustang and I never was happy with it on my terminator x so I purchased the accufab adapter with GM IAC and it works soooooo well it took me a year to figure it out the IAC would never be consistent and coming to a stop my idle would drop below Target RPM and slowly recover (ford pwm IAC) I did everything possible to figure it out until I was on Holley's forum and read you have to flip two of the wire's on the Holley 4pin IAC Plug because Holley's harness is wired for Holley/Chrysler IAC. GM IAC stepper motor for the win...............

Amazing video my friend !! Congratulations I.m from Spain and dont find people to know about holley terminator x max. I bought my 1971 mustang mach 1 last yeat in EE.UU. Texas and is very difficult for mi tune this EFI. So tour video is pure gold for me!!! And very helpful. I will try to change the configuration to find a goog tune. Tks a lot and if you come to Almerìa ANDALUCÌA, Spain... are you invited to eat a paella on the mediterranean beach and flamwnco party!!!! 😊😊😊❤❤❤. We are in contact and i will say You how is the advance with my old mustang. Cheers

Thank you. I am having issues with my idle right now.

Great content

You rock!

Thanks for these videos man ..I have a 93 mustang gt I just got this installed now my car ever time I rev it up it stalls no matter in park or coming to a stop driving ...and am new at this terminator

grat video tnks for the great info! but now I have the Issue that on hot star ups the rpm goes to 3000 and stays there I finally logged it hopefully I can see what is going on

Thanks for posting, I have never really liked how the IAC works, but have not taken the time to play with it. This makes me want to try to make it better! What frequency do you have yours set for?

Thank you for the video, it help a lot on my foxbody. One small issue I'm having is the car takes longer than I'd like to idle down. It hangs at 2400 rpms for about half a second longer than I would like. What changes would you recommend to help with that?

I’ve seen on other post and the directions of the term x that you have to go into the program select pwm in the soft ware and then you have to select it in I/o and drag it to the b3 pin for the iac to even work. Did you do this before making this video?

Do you know can you adjust fuel compensation settings from the handheld or does this need to be done from a laptop? Just started the car for the first couple times idle ls rich and the fuel compensatio is -50 which is the default I think.

What version software are you using? maybe that idle issue was fixed in the latest firmware?

i have a question? is your iac set on stepper or pwm? i was told it needs to be set on pwm and pin it to number 4 and my iac hold goes crazy after i let off the gas

I've got a 5L with a aod on it. What do yall recommend for iac parked position. I can get it to start but sometimes it takes two cranks. Also, what's going on with your fuel pump prime or that first fuel shot while cranking? Do you like more fuel or kinda how these systems come stock?

Took my fox out for a couple boost pulls and when I came to a stop, the idle stayed at 1500rpm... I replaced IAC and tried adjusting idle screw to no change. What else should I check?

Would a different cam (bcam) effect the idle settings as well? I’m having surging issues and stalling while decelerating and the car isn’t enjoyable to even drive.

I got an 87 gt manual, mine is running really rich, and no shops here in Clarksville tn know how to tune the Holley terminator can you help?

Will it start without the IAC sensor connected?

Installed a Terminator x on a 94 f150 5.0 manual trans. It has a slightly bigger camshaft than stock and the idle isnt the best. Would the settings be similar to this videos?

I have a 1994 ford Lightning, I had a mechanic shop install the terminator x, 24lbs injectors, aluminum heads,it’s cammed, my truck struggles to get past 3000 rpm and won’t accelerate any help ?

How would you do it for turbo cars

I can’t get my car to even idle at all

Everybody wondering why your fox still runs like ass after doing all of this. Can the Can bus plug from holley for 60 bucks and a laptop with windows. Download Holley terminator x software and change your IAC to PWM in the settings and drag PWM to the outputs. Night and day difference and car runs like a dream. You can only do so much with the handheld. The laptop is definitely what you need to get it right.
