any questions about the carb cheater stuff, feel free to ask - most of this project has been built off of solid suggestions from you guys - heck, one of you out there even came up with the name. (were the designers and programmers behind it) Heres the 0-60 datalog, this is exactly what you would have with your own carb cheater also: thecarbcheater.com/?db=9xdmz also, heres a log file of us turning the CC on and it doing its adaptive AFR control stuff: thecarbcheater.com/?db=S1tn8
@Jason Axelson I dont recommend using a carb for blownthrough. Unless it's only going to be doing wide open throttle, they are very difficult to tune well for all driving conditions. Draw through is no problem
I really like the carb cheater concept. Simple yet seems very effective. I’ve had people question why I didn’t go with a “self tuning” efi kit for my 79 Bronco and choose a carb. Cost and simplicity. I’d love to get my hands on a carb cheater.
You should send bill one of those from old man garage RU-vid channel he is a big carb guy and has there own carb line they do a lot of racing.. his son has a big RU-vid channel to it's SRC street racing channel.i think it would get your product out there to a lot of people that would be able to put it to good use.good luck on everything buddy.lovd the channel
I agree he knows what he’s talking about instead of making something up like other channels but that is the most used statement on RU-vid. Almost every channel has someone claiming the same thing in some form or fashion.
I think you're going to see a big market for the Carb Cheater once you really get production up. I think ALL the old muscle car guys who are CARB ONLY and won't take the plunge into EFI just don't' want to deal with the computers and all, this thing is a GAME CHANGER! I love it!
We also worked hard to make it under 400 bucks where even just a wideband alone (we have one built in to ours) is 200 dollars now. And even with efi, your still going to be tuning unlike what people seem to think. Personally I'll take a carb any day (and I'm even a heavy programmer by day at work, so that's saying something)
Agreed. I'm in the same boat. I appreciate the honesty and hard work you put in. I feel like engineers are of a dying breed today, software is one thing, but hardware still keeps us moving forward and with today's progress and controllers we really can do anything.
Luke is so down to earth and humble. Honest about what he knows and what he is teaching himself. Has no problem venturing into what he is not familiar with .Luke and his business partner are gonna go leaps and bounds with their cheater carbs product
Amazing development of your product, Luke. Pretty mind boggling that it went from this little idea.....to developing all the peripherals needed to make it work, including a phone app. You're doing amazing work!
The 300 is a legendary offering from Ford..It has a cross drilled, forged crank..like a 427..it has forged rods..it has forged pistons..it is a beast..Power Nation built one that made over 500 hp and over 500 ft.lb. of torque..I had one in my 1981 Bronco, New Process drive train for 475000 miles..before the body rusted off of the frame..everything else was fine..Long Live the Mighty 300 !!!
I went searching for a 300 and found one finally in an old 70s telephone truck parked in the woods in Tahoe. I have it all fixed up and running good now with a flat bed and ready to work!
I'm gonna turn 59 pretty soon. I don't know much about engine mechanical work except for the stuff I watch on RU-vid..... Thunderhead 289, Junkyard Digs and Mook, Dylan McCool, Sleeperdude, and Halfass Kustoms. With all that being said, Thank You, Uncle Luke, (remember I'm turning 59)for this super Awesome content, your creation/invention and knowledge you share with your viewer.
DAMN, YOU GUYS ARE AMAZING ON THIS PROTOTYPE! THANKS FOR TAKING US ALONG ON THE RESEARCH AND DEVELOPMENT OF YOUR CARB CHEATER. IT'S GOING TO BE A HOT ITEM. GREAT JOB. IT'S A BIT OVER MY HEAD BUT I WILL KEEP REVIEW THE VIDEOS UNTIL I GET IT. LOOKING FORWARD TO THE NEXT TEST ON A DIFERENT CAR/TRUCK TO SEE THE COMPARISON. AND PART 3. ONE MORE THING, WHOEVER DID THE COMPUTER TESTING PROGRAMING DID A GREAT JOB, TOO.
I have a 68 f100 3 on tree and a 240. They will run under any condition thrown at it. A pleasure to drive when tuned right. Looking forward to being able to purchase your setup one day
I have an old Datsun 280Z that I’m converting from factory EFI to a carburetor setup. I’m liking how much this would help me tune a dual carburetor setup! Subscribed and turning on notifications on this one!!
Really incredible that no one has come up with this in the era of small-form pcb’s. I know that this is really just the tip of the iceberg and I’m glad to be here to see it. As always, I enjoy the informational videos on these old rigs.
He has a video where he had some fun with his garage door control in the house he was at.. I love the small form pc stuff (arduino is amazing!) controllers for days.. not professional with it, but I really love seeing it used in the real world. My friend was lead engineer over at Crestron back in the 90s 2000s, the beginning days of home automation, before the pi came out.. Fun and you can do ANYTHING with it
It's nice you walked through the process of correctly identifying the resistive lead, pointing out the difference between the engine not running and then running. Great video!
I really hope a few of these make it to a high school shop class. I think using these to do a unit on how the components of a carbureted engine work together would be amazing.
I cannot wait to buy a carb cheater unit when you guys make it available. This will be the perfect setup to fine tune my woodgas powered projects and bring the manual/analog woodgas air fuel mixing into the current century! Keep pushing the envelope Uncle Luke!
Great idea to use the Carb Cheater on your woodgas engine. What is the AFR range for woodgas? I've never even pondered that before. Wood gasification is fascinating to see & study but looked complicated to operate. Good luck!
@@PaulThomas-qo9vy The ancient rule of thumb is to hit a target of 1.88 to 1 woodgas/air mixture. The old fashioned way to hit that target is to introduce air into the woodgas before the intake via small throttle body half the diameter of the total intake diameter. Using a choke cable to regulate the mixture which varies by quality and humidity of wood fuel, gasifier temperature, hopper conditions, etc etc. I would love to see how the carb cheater reacts to that with providing PWM signal to a dedicated electronic throttle body to provide sole fuel mixing without a carburetor in mind. This is already a much better system than my simple arduino/PID setup that just monitors hi-low readings of a target AFR and then adjusts a servo to move the throttle body to reach AFR goals. The user interface is a game changer! Count me in for instant purchase.
A lot of people find going into the data / numbers more into this mechanic stuff kinda boring, (myself included), but Luke is just such a nice dude, that I will always like and share his vids for that fact alone. Dude seems to be a legit salt of the earth cool fella
Hey Luke. Sure enjoy seeing the old truck percolating like a champ. The old 300 is/was a great engine for working trucks. Keep the videos coming. Thanks.
I love this. This is my mindset, and my train of thought exemplified but a smarter and more motivated person. I dont want 35 computers, but im not anti tech. Dont make it more complicated, make the most simple thing better. This carb cheater is genious and i hope you stay safe because there are alot of powerful folks that are going to hate this. I dont need sniper efi, i need my carb to be smarter. This is plain awesome and thanks for sharing
Making a carbureted vehicle absolutely efficient and consistent, it's a great idea. Luke I wish you all the best with this exceptional product. I love you videos you're really informative and thorough. Keep up the good work dude 👍✌️🇺🇲
Stay with it Luke! I am confident you will succeed with this endeavor. I have an old '84 302 that I have thought about reviving for a daily driver, but I know the 2 barrel will need attention. I would also like to get more than the 140 hp out of it. I was going to get an aftermarket carb, but maybe you have a better solution here.
@@Bender_B._Rodriguez The 302 was introduced for 1968 models, reguardless of cam it's a 302(I have one in a '69). The 5.0 moniker was first used on the '78 Mustang II, continued into the Fox Stangs. For '80-'82 there were 255 versions but 302 were produced for all years '68 thru '01.
Hey Luke, just wanted to say thanks to your tinkering, you've inspired me to start working on my hall effect speedometer/odometer Arduino project again. Keep up the good work, as always!
Hey thanks "Science Guy" for understanding and demonstrating how a load affects a resistive circuit and reading it with just a meter doesn't work (IOW having the load on the circuit, then measure). I tried explaining this to Derek over at VGG, and got treated like a wacko. Maybe you should send him this video......
Joe is really smart - I'm pretty dangerous with circuitry, Joe is really darn good. Not much slips past he and I together. He's got me a few times like that, done a heck of a job bulletproffing our circuitry. Carb Cheater wouldn't exist without him, that's for sure.
My 76 F100 with 300 6 had an emissions rail plumbed into the head at each exhaust valve. I castrated the emissions and plugged holes with 1/2-20 set screws much like someone has done to joe's. I would guess your 300 is a 76-79 engine. As a 300 6 fan, your last two videos have been very interesting ! Thank you VERY much and keep up the good work !
Very few and far between, the people like you with a wealth of knowledge. Makes me feel sane hearing about the resistance lead. Can't tell you how many times I've argued with people about removing that, lol
My dad had a 1967 F100 long wheel base with a 300 in it that was a good truck .it would go from 0 to 60 a little quicker than what his does it was a 3 speed on the column
Hi Luke and Joe! You know by now, all the big boys out there, (Holley, Edelbrock, etc etc etc.) are taking notice on the Carb Cheater. I am sure you applied for a Patent, TM, Copyright or whatever you can get on your product. When you get to the stage to market this, I would love to preorder one. Thanks much! Cheers from Motown/Dearborn.
I just did a lot of work on my cousin's 85 f-250 with a 300 six. My cousin is not one to do much to it except regular oil changes. So the spark plugs were the ones that were in it when he bought it new. So a full tune up. Also i put a four barrel intake, headers, new exhaust. Ect. Now it runs like new. And he is getting better fuel mileage. He is happy.
If you wire them as per the directions and use the specified coil, they never die. I've collectively put 180,000 miles on pertronix stuff without a single failure
The 300 heads have 2 different style rocker studs, one is a non-adjustable pedestal style, the other is an adjustable style. The rockers from a head from 84 and newer is non-adjustable, just tighten to the torque spec, 83 and older you adjust them like any other rocker adjustment. From what I remember, the non-adjustable style have a shoulder stop. That one looks like the adjustable style.
I hope so - so much of carb tuning is expirience. Carb Cheater does a really good job of bridging the gap of understanding. Most people going efi, really that's all the info they need at their disposal to succeed
@@ThunderHead289 I'm pretty sure you're the only person online who has really broken down carb basics for the masses. Unfortunately I forget things super fast. You know I'm a supporter!! I've already got a carb cheater earmarked for a summer project :)
Best truck I ever had was a 70 150 w/300. Just breathe on the key and it started no matter how long it sat. I might've flogged mine to about 4k before shifting it I wanted to brag about speed.....LOL
Yeah as far as I know pretty much all the 300's had hydraulic lifters and you just torque the rocker to spec, and any excessive lash/noise from there on would be lifters on their way out or already dead. In rarer cases a bent pushrod. I had to call my dad on that one and he agreed he couldn't remember any of the other big 6's (300 series) ever having solid lifters
@@ThunderHead289 Let me rephrase - non-adjustable is what we had thought. Preload on the rocker sure but as far as lash adjustment you just get what you got out of those for the next 30 years lol.
I started with Chevy V8s with adjustable valves back in the 60's. Then I bought a 70 Mustang new with a 302 V8 that had non-adjustable valve rockers. If I remember correctly the way to adjust the valves was to collapse the lifter, measure the gap, and use longer of shorter push rods to get the adjustment correct.
You guys do great work! Aux relay ideas: RPM based exhaust cut outs maybe, or would it be vac based? Hmm ... variable tuned length headers Muwahahaha... all of the scavenging!
I’m sure someone has mentioned this before, but I looked through every Alice in changes song I had access to to find the song in his videos. Turns out it’s a band called skorned. The song is psychosis. And it rooocks!
an old man on my block has 2 of those both kept cherry in a pole barn he built just for those trucks lol him and his wife always drive em in holiday parades that year model always looks sharp even when there "patina " everything
I had a 1967 mustang with a inline 6 as a teenager I ran out of oil. All I had to do was add 3 quarts of oil and was good to go. Can't beat those old Ford 6 cyl.
Valve adjustment info is dead on. Have been doing it for years. Couldn’t tell you how many thousands of valves I have adjusted NOT on TDC. Been trying to explain this to different mechanics, unreal how many people don’t understand basic engine theory. Good stuff
Keep at it uncle Luke, I always enjoy the content and information you provide. I'm old enough to be your uncle but dun matter. I'm interested in this fancy gizmo for carbs mate. Would be awesome to have one on a few of my old vehicles. Cheers from Australia. oioioi
The same resistive lead issue comes into play when converting an older GM engine from points to the GM HEI distributors. It WILL run, but like you said, not quite right and the HEI module will not hold up long term.
I’m working on an old F150 I bought with a 6 in it too. 1985, converted from feedback carb to duraspark. I’m new to vehicles entirely, and I’ve done a bit of work already on it. The resistive lead has me interested. Need to figure that out.
Is glad to see you making videos Again Uncle Luke It's pretty amazing what you can do with that carb cheater Is it blows my mind I could listen And learn new things from you all day long Is that's what I love about your channel Is not only a great content Is but you actually explain So even somebody would Is my abilities Is kinda understands what's going On you and Kevin Brown Are Just amazing what you guys can do Thank you once again for all your hardwork and great videos
Really like your choice in vehicles to work on, not Junk like so many channels. Hey, proper bolt torque is a procedure: clean and lube the threads, then pull in a single smooth pull till the torque wrench clicks. Pulling on a tight or torqued bolt is not a real torque value as friction between nut and bolt is higher than the actual torque. Also, you can change the rocker stud and nut for a Chevy style adjustment that allows you to set the lash, the "zero lash plus 1/2 turn at TDC".
. I just wish someone could have made the carb cheater 10 years ago when I started out - would have been a cake walk to learn carb tuning. I got here the hard way 😅
Hey that's awesome you made another video ! I'm the dude that talked to you at the git n go truckstop ! I seen your badge for work but I couldn't read where it was for. Anyhow keep up the good work !
You could probably add a 0-60 timer in the app. Just need to also add in the G senser from the phone to initiate the start time. Since gps will wander even at a stop.
Mines rock steady - i programmed it to hard lock onto gps vs passive or fused provider scenario. I could put a 0-60 timer in there but to be honest the app is super fat already as is. I'll look into it though and see where I could put it without slowing anything down
@@ThunderHead289 Id put it as a selectable option hidden in the settings so when nobody is testing its hidden and not wasting and processing power or screen real estate.
Could those spacers be black bi-axil glass? Hmm.. On another note glad you started up your videos again. Thunderhead you didn’t know it but you guided me through my first FE390 build!
Great stuff Prof. Luke & Joe! Question: Will you expound more about the hypothetical Draw-thru carb Turbo 300 setup? How will that tuning differ from N/A tuning, considering increased dynamic compression ratio under boost & related Low Speed Pre-Ignition or detonation. Can Carb Cheater vary AFR in relation to manifold boost pressure since the CC on an N/A engine meters & vents air below the throttle blades into vacuum in the intake. Give it a think. Thanks for a reply! Waitin' eagerly for part 3 ! Thanks Luke! Paul from S. Central Tx..
All I would do is use a 2.5 bar absolute pressure sensor and tune for high load afr. Wouldn't be no thing. Draw through though, yeah I wouldn't use this for that
@@ThunderHead289 Will that 2.5 Bar map sensor be read by the Carb Cheater & be displayed by the software on the hypothetical 300 cid Draw-thru carb./Turbo combo. The goal is less than 40 % power/torque increase at WOT, plus all or better "fuel efficiency" (light throttle) Increase of the N/A CC combo. Is this unreasonable to ask of the CC draw-thru carb.-Turbo combo? I appreciate your input. I even plan to use twin parallel new diesel EGR coolers as hot coolant heat exchangers/vaporizers down stream of compressor outlet in this CC draw-thru carb.Turbo combo. The CC seem like a quick & easy way to tune such an experimental combo. Your Thoughts Prof. Luke?
Please please consider expanding this project to people who just want to use it as a pre obd2 logger. I run TBI on my late 80s cars and want this to see if the ecu is functioning correctly (receiving the correct data from the numerous temp and pressure sensors etc) with the correct AFR. Also want to see my 0-60 logged etc in that beautiful graph.
It's been a while since I've had my 300... but I think the injector ports are on the intake manifold. I think the points you were pointing at were for that emissions stuff they had on the 80's model 300s.
Hey Luke, i got an 1989 f350 with the big ol 460 in it, its sadly an EFI instead of a carb but would the self tuning efi work for better mileage or would ripping out the electronics and slapping a carb with the cheater be my better option? Currently running with a 3.55 rear and a 5 speed manual trans with a granny
I am super intrigued! I have a 79' 350 Chevy v8 in my 65' GMC, and a 600 cfm edelbrock. I would love to use your carb cheater! My carb has an electric choke and I have headers and a TH400 3 speed transmission, Do you think the " Carb Cheater" will work?
