Love your videos. The tuning end of our world is what keeps old timers like me on the sidelines with the modern motors. Appreciate you taking the time to walk through it. More terminator x for beginners vids for us old pricks I say!
I would love to see you really make a video with you adjusting the fuel table and explaining how you are doing it and maybe showing fuel map that is tuned so we have an idea how a fuel map would normally look
For reference, when you tune with Lambda your target vs reading can be expressed as error in percentage. Say your target is 1.0 (14.7:1) and your wideband says .80 you just add 20% to that point on the table and you will get very very close to your target.
I have been watching your videos for a few months now and because of you my twin turbo LS is running better that ever. Thanks and look forward to more videos
I think your aif/fuel explanation is spot on. There are to many variables where you can end up with 1 or 2 lean cylinders and then pop goes the weasel, besides timing makes way more diffrence in power gain or loss compared to a/f ratio. So keep it closer to the fat side where you can keep a little more timing in it to make your power. Then if you really feel good about your tune and motor and chasing every last bit of power you can lean on it and push your luck! Just my two cents
*Im basically just learning (my 74yr old friend has Thruster dfi) and he couldn’t get it running, ur videos/explanation is very helpful!* I got his car running better but it won’t hold idle hood when u whop throttle it will backfire thru exhaust if u try to rev it back to back, it will take 1200 to 5000 Rev Trying learn this old system so he can get it on street before he dies if yah get my drift 👍🏼so thanks for doing these videos
I’ll try my best! Just takes a lot of time. Probably wouldn’t guess it from looking at it but they video probably took 10 hours to film and edit. I need to quit making them so long!
Great video man. It really helps us beginners get an idea where to start relatively safely. Keep these videos coming man. Your channel is gonna absolutely blow up. Just keep doing what u do.
Much appreciation to you guys who make these videos to help us old guys out. I overthink everything so the videos you create really help out. Thank you!
Keep up the good work Joe quality content as usual and keep bringing videos like these it really helps out alot of people that are new to tuning understand things alot faster.
Dude, you are the Man!!! No bs. How about doing something for carb tuning with HEI Distributor! I appreciate the content and the way u explain it is easy to understand
I totally agree with your comment.. make the car happy at idle. any performance cam overlap at idle can't clear a cylinder with such low velocity, so any fuel added is mixed with remaining exhaust in the chamber from the overlap of the valves.. the value the sensor sees is basically irrelevant.
Excellent information on the LS platform likes a richer A/F, found that out on the engine dyno with an LS3 with a Terminator, best power (N/A) on that engine was 11.8-12.0. Great videos as usual Joe.
This video really helped me heaps. The way you simply explained the overview was super cool. I have a New Zealand Link ECU on a Toyota 3sge Beams with ITB throttles.Your video helped me just get a overview and a good feel of how it works.
My boy Joe Simpson! Love the channel stumbled across a couple weeks ago and burned through most of your videos. I’m trying to learn to tune my 2JZ with a FT550. Would love a tuning series on FuelTech like you did Holly! Look forward to more content
Maybe you could do one on pin outs. Boost by speed. trans brake launch enable. TC switch enable. Thanks for taking the time, your good at it. That radio show went well .
good explanation. I like how you explained that you should give the engine what it likes AFR wise. Some people get so stuck on having cruising being 14.7 and only that or if you are at even a pound of boost you need to be in the low 11s and it very much depends from engine to engine even if they have the same mods sometimes.
I really learned a lot from your explanation of how to get to a usable afr on terminator x. I'm having a problem with updating my firmware to the newest available, maybe you could do a video breaking it down more like on this video. Thanks!!
Joe if you came to canada you would be a millionaire in 6 months for sure bro the guys are charging $2000 to $3000 to tune cars here and not as good as you I wish you can make me a good tune for my on 3 turbo fox body I have the terminator x in my fox
Great series. I didn't quiet understand the beginning when you were raising the setting the AFR and Fuel tables VE to a constant number and then switching to Speed Density and changing to the highest lb/hr fuel rate in the tables. Finally, I would love to see more information on starting a Fuel Table for VE% other than selecting one of the Holley preset tables. How is VE calculated from base engine specifications? Thanks again.
Those were just arbitrary numbers to show if your in VE based, the table values won’t change when you change the target afr. But if you are in speed density mode, the table values will need to change
Another great video! I have what you called in another vid injectors not worth owning lol Bosch 210’s that didn’t come with any information data. I just started running VE table. It’s a bit of a fight getting it to idle without hanging or dropping really low, I’m still trying to learn the system. I had the car remote tuned but I wasn’t happy what I got for my money. Sensors weren’t scaled cold start sucked the dyno graph was really wavy
Do you do any over the net tuning I’m still having issues trying to get my terminator tuned right the car wants to die in gear idles fine but second it’s in gear it wants to die
Great video Joe! One question though, if i have an existing tune with populated base fuel map and learn % and I now change the Target AFR table, do i need to delete the learn % and redo anything in the base fuel map? I did the above but my AFR jumps super high on deceleration and now stalls.
Jason can i get your info i would like to get u to look at my terminator file i have a turbo 5.3 in a pick up and cant seem to get it to go . I am a newbie to this so i am sure it something thats not maped correctly ...love the videos Thank you
Because the wideband reads an average of all 8 cylinders in a downpipe, and the Holley closed loop fueling will adjust the final afr to your target (let's say 11.5 afr for example)....what happens when you make 1 or 2 cylinders 5% richer with Holley's individual cylinder fueling? Wouldn't that make the average afr detected by the wb o2, richer than 11.5 afr, and then force the fuel correction to take out fuel to reach your 11.5 afr target? Or does it automatically make your global afr target value richer if you make individual cylinders richer?
I got a Holley 558-108 Terminator X system. With an LS sub harness. Here is the interesting part it’s going into a 97cobra motor. Ford Had a 2coil set up. My questions is after I install the firing order do I repin it at the harness?
I think you do a great job, do you have any street tuning, I don't have any dyno people I trust close by! Any help would be appreciated! Maybe a new video subject!?
You are definitely put in the terminator x all star award bro. These kinds of videos are very helpful to a lot of the people who really need great info. Devin’s videos are definitely also a big help especially to the guys who can’t seem to understand that the power wires go to the battery
Been watching your videos very informative👍) but unfortunately it's lost on me, I'm terrible with computers and the one I have is out dated, do you or do you know of a mail order tuner that dose terminator x, I have fresh running install but can't do any" learn" driving as I am waiting on a drive shaft, thanks for any advice
@@angusyoungsg yea I’ve watch that one put always interested in how others do there, Matt does one for basic set ups. What about for Big Cam decent performance heads and a victor intake
Thank you for making this great video series. I have learned a lot, but the videos have also generated a lot of questions. Several times in the video, you say something to the effect of you just need to "play with" it. It would be very helpful to understand the input and outputs I need to "play with." In this case one of the inputs is the "target AFR", but are there other parameters you adjust during this process? Moving to the outputs, what parameters are you looking at? Clearly the O2 sensor reading is one, but as you pointed out in the video you can't fully trust the O2 sensor. So, is this process something I can do without a dyno or is the dyno the primary output tool to understand what AFR my engine likes best?
You say that you can tell a problem just looking at a VE graph. I put a holley base turbo tune and the holley adjusted it self and had peaks of like 103 at 2500 to 3000 at -10.3 (i have axis in PSI) reving it in park.then in less vacuum it dives down to i guess normal but its much lower VE
@@JoeSimpsonAtTempest its going to be tuned on tuesday because i give up. Feel like i drive it and it just keeps changing the same blocks over and over. Your videos do help i just dont want to replace motor.
Exactly why i suggest turning the learn off. You will run around in circles forever. The system is NOT “self tuning”. It can make enough adjustments to get you to where you need to go to get it tuned, but it doesn’t simply tune its self
Dude, thank you for taking the time to make these videos! Ill be trying to tune my own car for the 1st time thanks to you. If that doesn't work I will head your way from northern va!
Question I did a term x on my buddies truck. SEP 1500’s on a TT sbe 4.8. The ve at idle wants to be around 5%. On my car with DW 1500cc idea around 30. Both on flex fuel. The truck keeps asking for less fuel. Would you know why?
Do you install rear gears? I have a foxbody that I want to go from 3.73 to 3.27. I have the kit just need it installed and would have you do the tuning as well.
im gonna be running the holley terminator x on my 6.0 ls single turbo. Im gonna be running pump gas and e85 [flex fuel]. will the holley adjust afr based on the ethanol content?
Oh shit! Just hit me! KaPow! (😂 old batman) I really would like your opinion. I was watching another vid, 🤟🏻🤟🏻 channel by th way, and you said you really dont care for Innovate AFR meters. I almost went that road but ended up going with a PLX instead. Any opinion on thiese guys??? Cheers! 🤙🏼
Hey Joe - with Megasquirt, playing with the injector opening time messes radically with the fueling because it adds that time to the end of the total fuel calculation. Does the Holley system do the same or can you really mess with the minimum opening time on the fly?
I'm putting together a fairly basic setup. Stock intake manifold and ported stock heads. I have access to the factory calibration and they have individual cylinder offsets in there. Is it worth transferring that data to the Holley? Small block Chevy V8. Not an LS. So I'm assuming the factory was well aware of a distribution issue and accounted for it.
Is it best for naturally aspirated without timing control to have that progressive AFR set based on rpm and psig in normal driving? A lot of afr charts I see only have 3-4 total afr targets in a blocky fashion
@@JoeSimpsonAtTempest logically it makes sense to smooth but yeah not sure why some keep stock block fashion. Wouldn’t mpg be better in closed loop w smooth?
Thank you for all the information. I normally tune on AEM infinity. Similar concept. Just wording and commands are located in difrent spots. Does it have (undo command and commit command? )
Undo is control + Z. Some situations it doesn’t work but does in most. Commit, not really. Everything is real time. The screens that are not real time are greyed out and will require you to cycle the ignition. A box pops up to let you know when this is the case
My holley is on the way can you tune in lamda to allow for running flex fuel e85 and pump gas to cut out the diff in afr needs for a given fuel? Lamda is lamda but afr changes based on fuel.
I thought I wanted fuel injection, then a sniper, then sniper2, then a 4150, then a terminator X. Now I have to have a laptop. This is snowballing me into keeping my carb.
What's a good air fuel ratio for a supercharged car it's a procharged fox body 10 lb of boost... You said a good ratio for na and turbo didn't say nothing about the supercharged just curious as I am switching from turbo to supercharged... Thanks your videos are great.
@@JoeSimpsonAtTempest Spotsy. In Oct I'm installing a DART 363 and transferring over my HOLLEY SUPER SNIPER and ON3 turbo. I've played around with the software with my current set up, it just isn't where I want it.
So I oknow you're not a fan of the base maps and self learn but if load a base map for my basic turbo ls will that be ok to drive around a little just to break in the clutch and be make sure it runs ok before I take to get dyno tuned?
That’s what the base maps are for and they do a good job of that. The closed loop and learn works great for that situation. I’m just not a fan of people thinking that is going to tune the car and then they plan to leave it like they forever!
do you have any videos specifically covering utilizing or not utilizing LS knock sensors? if not, do yo use them? i have been doing a bunch of research and theres a bunch of different info that contradicts itself. just curious if i can "tune" them to knock throw a false knock on a 5.3 turbo setup. thanks for any input
@@JoeSimpsonAtTempest it worked it was at 2.0 ms lowered it to 1.75 learn was still taking some fuel out it was idling at 1.75 so i lowered it to 1.68. I didn't read my data sheet right its confusing the graph shows min injector open time as 2.0 but thats at 20% duty cycle so I'm guessing I can put it as low as 1.0? Or maybe .5? For 5% duty cycle
Hp Tuners/Pro EFI=Kid Mode. BIG 3, HOLLEY EFI, Haltech, Fueltech They all have their troubles. Stochiometric 15:1 (too lean) is ideal scientifically but 12:1 is used for cooling.
