Carb Cheater is now publicly available! This video is posted for those who own, or have ordered a Carb Cheater kit, and like me, you dont like reading instructions! to learn more about carb cheater, go to thecarbcheater.com or stay tuned! (Go to "store" on website to buy a kit) Currently no ios app, a cheap 50 dollar amazon tablet works just as good. Tailored to V8 or big 6's at the moment. big thanks to all the Beta Testers who participated and helped Joe & I bring carb cheater to the public :)

Ive said it before, i really hope your patents and stuff are in line because all the big dogs in the industry are going to absolutely HATE this. Love what youre doing bud keep it up. Truly genius

Thank you so much Luke for all you've taught the carburetor community, you sir are a true national treasure and a genius!

I think this product is a godsend, there are still a lot of us older "gear heads" that like carbs. Sure EFI is "better" but there is a lot more to go wrong with EFI and it can be expensive to fix IMHO. If I could offer one suggestion, it would be to send a kit to your fellow youtubers, VGG, Junkyard Digs, DD's Speed Shop et al. and get them to install it on one of their "revivals" and have them make a video of the install and results. I think the more people see this being utilized by the other people they watch and hearing the positive feedback (which I am certain you would get) would go a long way in promoting and reassuring people this isn't "snake oil". Just my two cents. Wishing you the best of luck and hope these sell like the proverbial "hot cakes". Keep up the great work.

We're at a point where we can do what OEMs used to do at the end of the carb era, but with better and cheaper electronics. Congratulations on bringing this to market!

Hey Luke, just wanted to thank you so much for the continous resource and guide you've been on carbureation over all these years. I really hope carb Cheater as a brand is a big break for you and your team/family. You've given so much over the years, and it would make me super happy to see this product take off stratospherically in the car community for your sake. Keep on doing amazing things brother!

It's ALIVE! The carburetor world just changed for the best! Such a high quality & comprehensive kit, wow! Congrats., Professor Luke & Dr. Joe! Ya'll are my automotive heroes, along with Smokey Yunick! Ok, I've got to save up my spare change & dollars & get one now! Best wishes & prayers for long term successes! Paul from S. Central Tx.

Getting ready to place my order- it’s an honor to be able to pay you back in a small way for all the knowledge you’ve given so many people. I can’t wait to install it on my daily Fairmont (302/T5 with a Summit M2008VS) that lives in the mountains and sees a 1,000 foot change in elevation with just my work commute! I’m sure I’ll be buying one for my Galaxie in the near future as well.

Luke....you NAILED IT!!!! For what its worth thanks for keeping it simple and so darn effective.... WELL DONE 🍻

I'm in Australia too and very keen on one of these in the near future. Cheers for being awesome Luke and Joe.

Growing up in the 60s and 70s my father drove a 64 Galaxie 500. We had a lot of memories in that car. My mom drove a 63 Galaxie in the late 70s into the 80s.

Honestly, this is a product that could change the landscape of our hobby. Will be ordering soon. I love that you guys put your heart and soul into developing this. I hope this blows up for you guys.

This is a GAME CHANGER! BRAVO LUKE! I'm A 69 year old gear head. I HATE FUEL INJECTION! I have a Stock 1979 C-20 454 cu in Edelbrock intake and 625 carb that this unit looks like the perfect match for. Looking forward to your next video!

Its pretty amazing the amount of features you get for the price, I was honestly expecting it to be higher

After seeing him work on the prototype build, I thought it be really fun to make a rudimentary version. Obviously just amping the O2 sensor output into the valve soleniod isn't going to work, but it'd be interesting to see what that does and start from there, maybe then try adding, subtracting or compounding the O2 output with the MAP sensor output... Kind of like a CDI doesn't need to be perfect, it just generally needs to increase the timing with RPM. Some carbs may not need much correction, just to lean out at higher rpm or something

Please keep the tech tips in your videos. They are GOLD! Especially for beginners and hobbyist that don't do this full time.

You did it man!!!! I've been watching your videos for a lot of years and have always liked how you explained to people how engines tie and work. I have been around engines my whole life and am shocked at how well you explain things and also even back in the day just showing how a vacuum gauge helps tune and mpg. This is so cool to me that you have pu all this together. Technology has came along to the point of you capitalizing on it and making this work!!! Very cool man, very proud of what you have created!!!!

Great job Luke, i would imagine that the carb industry is going to latch onto this idea and try to add accessories for it!

"it is just a static metering device in a dynamic environment" Now all I can think about is Mongo is just a pawn in the game of life. Your product looks really interesting, I am glad you are sticking with this idea.

I've been watching you and Kevin for quite a while. I really appreciate your videos and all the tech tips. I hope you make big piles of money from this, and I wish you and Joe all the best.

This is a great invention for carb enthusiasts! I hope the product takes off for you, Luke. Great job as always!

Great ideal you just got another subscriber. Looking forward to seeing your next video. You have just brought carburetors back to life in a whole new world and thank you brother. God bless you and your family

G'day from Australia. Just wanted to say- please don't ever apologize for the tech tips mate, I'm sure I'm not the only one that appreciates them. Cheers and keep up the good work

Congratulations Luke. Looks really well engineered and well thought out. Good luck, especially with the help line.

Suggestion for improvement: For the mid-plate, smoothen, bevel, trumpet or cone the holes on your 3D-model. This way you'll have solid indication which side of the plate needs to face down, and overall better flow and performance on your kit. For the already existing plates, you can mill the underside to resemble a cloverleaf pattern, just round the outside edges, if the middle seems too thin to round off. 5-10 hp more on top of the fuel savings is worth it. Just don't call it "the cloverleaf" to avoid any legal actions.

Luke & Joe well done, will be buying one for sure, you guys were born 50-70 yrs. to late this would have a been god sent back in the day, not that it not now, good luck with your success.

Got to say, this is pretty nifty for the people new to cars or just carb tuning. Would be an interesting option for a headache free weekend cruiser that isn't efi too. I've been doing the grease on gasket trick my whole life. Dad was born in Tennessee up in the mountains in 1939. When he was growing up it was basically a requirement to keep sheets of gasket making material on hand to keep everything going on the farm. To prolong the gaskets life and help with sealing they would lather them in grease. When times were real tough they even cut out and layered pages of old mail order catalogs and thin cardboard boxes into truly backwoods made gaskets. They would take the layers and brush them in grease and then set them in the sun to get the grease to become thinner. Once it seemed about right they would take thin boards place the greased up stack of paper on it, place another board on top and then back the tractor on top on the boards to compact it all down. If the tractor was what was broken they would press them under the biggest logs they hadn't already split for the smokehouse or wood burner. He told me the gaskets would many times have a small trickle of fluid or vacuum leak initially. Once they were able to get some heat into it a time or two the paper would swell back up and the leaks would be gone. Some of them lasted way longer than they ever should have. 20yrs ago his sister sold their old family tractor which still had several 30+yr old homemade gaskets holding strong. They used all kinds of other materials at times too and another he said worked rather well was leather soaked in grease or pine tar. I've also used permatex 51845 without the activator on carb gaskets and air cleaner base gaskets with a lot of success. Seals great, doesn't really wipe away, and allows the gasket to be reused nearly indefinitely.

Good on you for actually including everything needed to install the kit. Things like the extended studs for the carb spacer, the fuse holders and the clamp on bung might seem small, but you just saved every single person who buys this kit a drive to the auto parts store. Great work!

Thanks for the tips Luke! I will grease my gaskets where applicable from now on. Will even save me some money in the long run 👍Also a good thing to note is that it is fail safe. When the Carb Cheater box fails, the carburetor will still be able to function.

Well I know what I’m buying for my old bull nose F150 next payday. I seriously cannot thank you enough for making this👍

I gotta check this thing out! I’ve been working with Holleys for years, and I know that there’s more to gain from them. I just don’t have the time. My car sits, more than I drive it. It runs well, but I believe it has more potential. You’ve got me really excited about this!

Giving your Dad a close ratio 4 speed for his truck is about as awesome as it gets!

Thanks Luke! Looking forward to diving deeper into the app. The system worked great right out of the box for me but now I need to PLAY with it. 👍

You forgot to mention one other permutation on the carb studs. Sometimes they are JB welded in the stripped out aluminum manifold. Very interesting setup and another great video.

Huge THANX Luke!!!! your abilities make me smile! Aint seen innovation like yours in DECADES!!!!

Wow $383 for the full kit is a great price compared to a holly sniper or something similar. I'm gonna order one before Holly or another company offers you a billion dollars and Jack's the price to $3k. Awesome product man.

A fellow Iowa resident! I've taken a recent interest in old Japanese motorcycles, and 4 carbs at once can really frustrate you. I'd love to learn more about how this system works to see if there's a way to make one for a 4 carb/4 cylinder cycle engine.

Absolutely love the tech tips, helps with keeping the old iron running good and easier to maintain

Installing ours this weekend so we can play with it next week! Looking forward to trying this little bit of dark wizardry out!

Incredible little setup. We all wanted this but there wasn't anything like it. Please don't up the price before I can get one on my car!

So a controlled vacuum leak ...simple and effective and what a blessing for folks who live in climates with massive temp and Barometric pressure swings... I fuel inject everything because I lean burn my gas rigs... But this is a decent solution for Holley and Carter that have less than stellar emulsion processes ...good job

Id love a break down of how this works. Because this looks like a really cool system.

I haven't purchased one yet but I sure plan to within the next few months. Don't apologize for all the tech tips, they are very welcomed and appreciated.

I give u so mich credit for doing this when all the heavy weights out there wont like it.great work.i also like how humble u are much respect

Luke, this thing is awesome, but you need a layout that is easier to conceal, because a lot of the people who will want this are keeping their carburetors because they are driving classics, and don't want the visual changes under their hood.

Nicely done Luke! Can this benefit a single barrel application, like an Autolite 1100 in an F100?

I'm glad Luke decided to make this for purchase. I am not a fan of carburetors but definitely understand their is a need. Good luck.

This looks like an awesome setup for someone who can't afford to go EFI or wants to keep that classic carb but wants something to help hold it in tune better. I can see this exploding in popularity because it's like the in between step between carb and EFI. You have a carb, then carb with the carb cheater, throttle body EFI, then multiport EFI. Awesome job guys 👍👍

How well does this work with an engine that has a larger cam?

Hey Luke, what will be the difference between beta and final version? When will final version be shipped? Is it worthwhile waiting?

I had an idea similar to this and was searching to see if it was a thing and found you. What you have done with it is beyond what I was even thinking. Like a separate cruise AFR! This is probably the best car product I've ever seen.

I'm scratching my head trying to figure out how Carb Cheater enriches a lean mixture (electric choke?). It's easy to understand how it leans the mixture. The real key to this obviously is the Wideband O2 sensor along with your software. Wideband sensors gave.give the average guy the ability to monitor the A/F ratio real time and not have to rely on the old method of reading spark plugs or having to go to a specialty shop to have tuning done. The easy availability of wideband O2 sensors (and gauges/software to read them) has helped carburated and fuel injected enthusiasts. Anyway nice work!

hi Luke , will you be posting to Australia ?

Got mine today. I'll probably install it tomorrow or Monday. Another way I like to drain the carb is to use a spray paint can lid to catch the gas

Wow! What a cool invention and a nice kit. It pleases me to no end to see an honest working guys come out on top for a change and hope you sell a million kits.

Now this is cool Luke! I can’t wait to get my hands on one! I have a 1979 nova with the 250 straight six and would love to put the carb cheater on it for fun and see how it works!

Very impressive creating a controlled vacuum leak to lean out a rich carburetor until the mixture gets as close to stoichiometric as possible. An elegant and simple solution to a limitation of carbs we've had to put up with for years.

I can’t wait to install this on my 72 C-10 step-side. You rock man!! Geek and petrol head/gear head, are a awesome combo.

I knew that you were going to be rich one day. Congratulations on your invention!

This is extremely intriguing, I love driving my T-bird but the gas mileage isn't great, so it sounds like this is just the kind of thing I could use to feel free to drive it more often.

Getting ready to make my order to stick it on my 302 in my old boat. I know you don't specify marine applications but I figured I would just try it.

I hope you can keep up with the demand! This is going to be great I can’t wait to see what everyone does with this thing!

Keep up the great work man. I've been in this business 30 years I'm quite impressed and that says a lot. Follow your dreams

i just ordered mine :) been a big fan of yours since years, greetings from the netherlands :D

why am i watching this? i don't even own a cellphone. best wishes for success, luke!

VERY IMPRESSIVE! I AM SURE IT WILL SELL WELL IN AUSSIELAND AS WELL. I WOULD HAVE LOVED ONE BACK IN THE 80/90'S WHEN MY CARS WERE ALL CARBED.

Dont apologize for the tech tips, we frakin' love them.

Just installed a 4-hole spacer under my Holley, and now i have to change the gasket under it from a 4 hole to an open one. You always learn something from uncle Lukes videos.

that thing you did with soaking your gasket in grease, i use oil, just before install, works great! lots of moped gaskets to done like that, no headgaskets tho!!

I just think this dude is brilliant. I'm glad i found his videos through his lawnmower carb experiments.

good idea!!!!......that valve is a 4 wire electric valve, it is a stepper motor bypass, air control valve, it looks like an IAC valve but here we don't just control at idle time , by the MAP sensors and broadband it can be deduced that the air control is at all times, very ingenious, it is similar to the EFI but instead of controlling the cumfuel injection (fuel supply), the carb cheater controls the supply of air, in both ways it is possible to reach stoichiometric mixture control in all engine operating conditions. .......... ...................... that reminds me of 1979 chrysler cars with california emissions controls, even though chrysler was already running the lean burn computer since 1976, the second generation was renamed spark control computer in 1978, chrysler was avoiding meddling with issues of catalyst, which General Motors did quite successfully from 1975, but Chrysler's computer had reached the limit of its emissions control capabilities late at 1978, for 1979 225 slant six engine cars sold in California , more control than usual was required. The computer had a feedback solenoid control module attached to the ignition advance control module, the solenoid did not control the fuel (as was the case with 1981 General Motors' CCC system or Ford's EEC-3), in the case from Chrysler, the solenoid controlled the air, the carburetor was a Holley single barrel, since it was a feedback system, an oxygen sensor was used to work in a closed cycle, the other sensors such as the intake manifold vacuum transducer, throttle position sensor, camshaft sensor, coolant temperature sensor, and others, were already there since 1976, so their signal was only taken from the feedback module (renamed Combustion Computer at 1979). For 1980 all Chrysler V8 Line-up play to Combustion Computer.

@11:15 using wheel bearing grease on fiber gaskets - related hack, I've used chapstick on Holly carb float bowl gaskets ;) I also use grease on cork/rubber valve cover gaskets, adhere the gasket to the cover w/ silicone, and then grease the side that contacts the engine head... use only enough bolt torque to arrest any leaking (contact, plus a quarter turn!) and I've open and closed the same valve covers repeatedly over 11-years reusing the same gaskets.

I've been wanting something like this for so long. Simple concept but... Genius!

I'm really excited to play with this on my old suburban that I pretty much test everything on.

This is sick! The wave of the future for carbed engines..................👍

Since different family drive different vehicles, one phone disturbed me at first. Looking forward to next video.

I want that as a shirt. "This is just a static metering device in a dynamic environment."

As someone who had never worked on large carbs (only ever done lawnmower stuff) this is *really* cool. It looks like it would take some of the mystery out of tuning, if I ever own a car with a carburetor I'm definitely going to put this on it.

Very impressive..good to see a young man realize his dreams..Don't let the top 1% steal this...

Me being old and was alive and rode around in the late 60's cars growing up, would have never believed you if you told me this 30 or 40 years ago.

This is brilliant great product what an awesome talent you have

Im a full stack c# developer, and with the newer .NET frameworks apps written with certian UI interfaces line UNO or MAUI can be run on any platform. I would love to help with the future software development on this project if you guys want it! This project is amazing and I look forward to seeing what it can do in the future!!!

I truly love your channel, inhave learnt so much from you. The way you explain things, making something potentially complicated simple and easy ro understand is an art. What you have done here with carb Cheater is amazing and fantastic, I want one. I will be e mailing you as your shipping doesn't include Canada. So I am hoping we can sort something out so I can get one as well. I live in Alberta not far from the mountains, and I own and operate a small landscaping business using a square body chevy truck as my daily work truck ( 1980 K20 ) I got the tune as good as i can as I got an afr a few years back after watching your vids about them. I maintain a good 14.7 however living where i do those temp changes amongst preasure changes mess with the tune all year long. I also plow snow with this truck, so Temps change 10 to 20 degrees over the day to night especially where I live when we get a Chinook. Anyway I had thought about getting efi but the guy said if i am diled in with myncarb as i am efi won't do much better. So seeing what you have made here will look after those changing variables that I deal with over the course of my day. Looking forward ro your response and thanks you for all the time and energy you have put into your channel and development of carb cheater.

This is going to be much easier to deal with and muuuuch cheaper than a new EFI system. So cool.

I think I remember how this product works and the one thing I can’t handle is the sound of a vacuum leak😂. Honestly it is a great product and you will benefit from having it. A wide band 02 sensor has really helped with carburetor tuning.

Love seeing the creation of this as it went on your channel. Great work and amazing

Now I have to buy an old Jeep so I have something to put it on. AWESOME IDEA!!! LOVE IT!!!

I've been waiting, like so many people, for this product to drop. My order is in 👍

This is fascinating and awesome, very cool. You answered my only question in the last 1 minute, you do not have to have the phone connected, the box will remember your settings.

Very cool product, I’m glad you came up with this, it’s genius and will hopefully help save the carburetor world since everyone is afraid of carbs and always pushing fuel injection, which I’ve never liked. Love my carbs, so I’ll be checking more into this. Great work y’all!

This has made my year, been keeping my eye on it and am super excited, wish my brain was as big as yours, will be ordering soon

Luke, you mounted that tac in your dad's pickup in the same posture that I mounted mine in my '71. Logical location.

I am so waiting for mine to come in the mail. Looking forward to the benchmark video. Great job guys.

Congrats - I knew about this and watched this anyway. I don't have any use for it but I gave it some thought and figured at what price point this would be viable and you NAILED it. Exactly my guess, I hope you sell a mountain of these things... wait, could I run this on my lawn mower?

This is pretty cool. I love this approach to learning how to actually tune a carb using tech 👌

An old school trick for you guys out there is to take a piece o vaccuum hose and interconnect 2 vaccuum ports at the same time, replacing those nasty caps. Also, use a bolt to plug an inch worth of vac hose in order to plug the ole ports real good

Nice to see the actual installation is as easy as possible I emailed last time you posted a video on the carb cheater as soon as you are ready to ship to Australia i am happy to be a paying local tester

My buddy and I have been having a debate for the past 2 years on what engine we want to swap into a project 1991 S10. Knew we wanted a V8, but weren't sure if we wanted to stick with an older generation smallblock or move towards an LS. I'm confident over time (and with patience) I could learn at least the general idea of carburetor tuning, but having the advent of fuel injection and HP tuners made me want to gravitate more towards an LS, which would've been a pain because the S10 already had a 1996 350 swapped into it. But having this as an option? All I can say is thank you, because this makes the whole process a lot easier, and I can simply forget about anything LS-related. I've got a feeling that it'll be less expensive in the long run too. I can probably get close to 95% full tuning with a carb given enough time, but this could get me that last 5% that's probably out of reach.

It is a simple way to add closed loop fuel mixture control to a carburated system during vehicle conditions where there is a decent amount of manifold vacuum :-). The gear head end user could use this to tweak the carb metering so that this system did not need to adjust as much.

21:00 my rubber thing inside the brake booster its broke so it will cause a faulty read ive noticed hahaha, good idea of the carb cheater men, its the best of both worlds in terms of efi and carbs!!
