How Tuning Engines Became Illegal👮🏻‍♂️| Explained Ep.26 

Imma still tune it 🤐🤷‍♂️

This is why everyone needs to support Right To Repair so that owning something actually means owning it.

“The cammed Z06 chopping across the parking lot is not reducing your life expectancy, when you probably vape.” This is a most epic statement 😂❤

Step 1: Copy Stock ECU values Step 2: Remove Stock ECU or bypass it. Step 3: Insert Modified ECU with enough memory to accommodate Stock and Modified values Step 4: add hidden switch that flips between both value sets. Step 5: Have Fun.

No matter how hard they try to control it there is always a loop hole somewhere. This car culture is unstoppable.

There needs to be a part 2 about how companies are building their own ECU's to keep the tuning game alive.

I don't own a performance car and probably never will.. But, I can sure appreciate the sound of a well tuned high performance engine that pulls up next to me at a stop light.

The infinite wisdom of the CAFE regulations also simultaneously ensured more people drive large, heavy vehicles like CUV, SUV, and pickup trucks every day. The calculation for expected fuel mileage uses vehicle footprint as a factor - as a result larger vehicles are held to lower emissions standards. This makes auto makers prioritize selling large vehicles as the profit margins are higher. The irony.

All these years and I’ve never heard any compare ignition timing to riding a bicycle… what an easy and universal way to explain it to the masses. Bravo :-)

I wrote a 5,000 word article on the impact Motronic had on Tuning for a publication a few years ago and I never felt I could do it justice. Glad to see such a great channel giving such an important topic some attention it deserves

The part about the EPA and CARB that's completely illogical to me is that you can't just swap in a newer and more clean-running engine to an older chassis and be all set. If they are truly concerned with vehicle emissions, let us do individual vehicle testing like on pre-OBD2 cars. If I want to build some high compression turbo motor for my grocery getter and it can be tuned to be at least on par with the factory engine for a vehicle of that age, and I can prove each year for registration that it is running that efficiently... get off my back.

I love that the EPA decides to focus on enthusiast cars that make up a small amount of overall emissions instead of going after commercial vehicles more strictly. *EDIT* Holy crap mom, I’m famous!!

Idk how you did it, but you upped the production value significantly. The music and transition between scenes is like really nice.

Man, it seems like just about everything we knew as regular, routine stuff is going away. Anything enjoyable, recreational, fun....the powers that be want to take it away or destroy it. What a drag.

Anyone else notice how hard it is to have fun these days?

No matter how much companies and governments crack down on tuning, someone is still gonna find a way to do it. It's basically an eternal cat and mouse chase.

The solution is simple. Just replace the whole ECU with an aftermarket ECU, one that comes with its own software, allowing the tuner to do what he/she wants. When it comes time for an emission test prior to registering the car every year, just simply plug the factory stock ECU back in, go get it tested, then, simply swap it for the tuned ECU. It used to be, "Bolt on, go fast". Now, it's "Plug and Play"!

Absolutely incredible production and explanation. Thank you!

Funny you mention bicycles! I have been biking neck and forth from work bc I’d only a few miles and I’ve noticed with my aggressive mountain bike pedals I can apply leg power in two different ways. Method one is like the video mentioned. Which mentally can be visualized and a up/down motion capitalizing on the leverage given by my legs and pedals, method two is where I use the grip of my aggressive pedals too silly power though nearly 360 degrees! It’s much more effort but the human body can adapt amazingly and with some practice I can accelerate MUCH more quickly by balancing the right and left leg/lever and applying as much power as possible through the greatest range of angles possible. It results in fast and effective get up at the cost of my muscles ability to endure long term lol

The EPA recently got into hot water with the supreme court over basically "over-interpreting" laws (Sackett v. EPA). Maybe in the near future they wont have so much power to shut down small tuner shops.

Amazing video buddy. Huge supporter of the amazing informative content.

As a tuner for the greater part of 23 years, bravo on this video. Well done and great basic explanations of basic functions to define a minimum knowledge base for your video. Very well organized and presented.

My god, I love these videos. Educational, inciteful and well produced. Great job!

This is why SEMA garage got involved. To do the CARB testing for smaller parts Manufacturers who cannot afford the test themselves.

Government always loves tackling the small fish for an easy target and easy money. Won't keep me down, can't keep us down! Keep rippin boys and girls!

Wow. What a masterpiece of a video. I can tell you put so much time and effort into this video and it shows.

We as a people need to stand up to these scum bag companies. We need to find out who the individuals are who think our property IS NOT OURS. ENOUGH IS ENOUGH!!!

Another EXCELLENT production, in every way! A+ Kudos. Subbed

I never knew it was illegal tbh😂

Love how FoMoCo has been totally hands off in this. Even allowing thier Engineers on their off time to crack/tune the cars.

These videos are absolutely amazing thanks man

This VOICE OVER is gorgeous ! This guy could be a hell of an actor damn it !

8:27 You technically can blame the coal rollers for this, compounded by the dieselgate scandal, the epa went at first to the diesel tuners and then moved towards the gas tuners as well.

I have yet to see an ECU that could not be cracked. The problem now is if you crack it, the dealer can tell and then void your warranty. Piggy back units are getting much better, and the good ones are completely untraceable. None of this has to do with clean air, it's all about squeezing money out of people. Luckily, modern cars are getting so good, you can have really fast car, and a warranty. I also think this is a big reason we are seeing the used car market go through the roof. Much easier to mod a 90's car and still get it to pass emissions, unless you're in the anti-freedom state of CA.

i’m a comp sci student and its always been a dream of mine to open my own garage for tuning my cars….pretty funny that cars were running assembly language programs at the same time as the atari lol

Another thing too is that in some cases you are better off swapping your ECU, but with complex programs that we have nowadays it is impractical to do it with newer cars.

Let’s be real, almost every WRX still uses a Cobb access port 😂

You have become the Morgan Freeman of tuning! Love your essays!!

I'm so happy I stumbled on this channel.❤

This is the best video on tuning I’ve ever seen!

In Germany, this is normal. I own a tuning shop and we actually do those emission testing procedures. For a simple ECU tune, you'll be looking at around 15-20k, if you pass the first time. Of course as a company, you can sell it to as many cars as you like - if it is the car you tested with the transmission you tested (can't homologate an automatic and then sell for a manual) The bigger Problem is the combination of parts. Since you can not change the code you've homologated, there's no costum dyno tune. Just a flash tune. Also, if you want to install an intercooler, and exhaust or even sometimes different tailpipes, you will have to redo homologation for that specific combination - same thing with intake systems and so on. Imagine having 3 products as a company. An intake (IN), exhaust (EX) and ECU tune(SW). If you want to sell them all individually and in ANY combination possible, you will have to do the following homologations: IN, EX, SW, IN + EX, IN + SW, IN + SW + EX, SW + EX That's roughly 105 - 140k in homologation cost only. Add an Intercooler and you could just buy a lambo instead. Yep. The struggle of germany. If you want to know what tuning looks like in the future, Germany can give you an idea

It really doesn’t help the people mandating this are so out of touch with the modern world, the one lady that was being asked about normal people racing thought all that existed was “NASCAH”. These people need to honestly be rooted out as any GOOD tuner makes your car run better than factory. Another HUGE thing is that E85 was completely passed up on and we went straight to electric. E is cheap, renewable, and can be easily worked in but no it all has to be electric.

In today's racing world, there is a huge difference between and real tuner and a computer guy. Thanks for sharing. Cheers from Motown.

I love that you showed Jay as the definition of a Tuner

love seeing brothas doing content like this

Can you make videos on why certain engines get a bad rep?

I parked my performance diesel truck in about 2015 and didnt mess with it until 2023, boy I didnt realize how hard it is to get performance tunes nowadays! Im pretty shocked how much the diesel tuning market has changed. I have 6.0 powerstroke and a LLY duramax and the tuning for both is so limited now!

this video is amazing showing the lamda and all that

I always respected what Dinan did back on the early days based on the tuned BMWs I drove from the 80s and 90s. His understanding of a car’s suspension is also masterful.

The insanity of government regulation is brightly highlighted by CARB. In 2002 an acquaintance of mine took his twin turbocharged '89 Mustang to get an emissions check, after finishing his projects. The brand new EP3 Honda Civic Si that was sniff tested before his car was running dirtier across the CARB emissions test run than the modified decade old Ford.

1:49 i have the exact same multimeter on my bench at home that is sitting on that dashboard. Its a Hewlett Packard 3435A.

Some tuning companies tune for emissions too. For example: when to open up the EGR valve or on a variable valve timing engine when to close the exhaust valve sooner in relation to normal valve timing.

5:00 - on a N/A motor 0% ethanol you target 12.5 - 12.7ish because that is when the burn has the most velocity and thus makes the most power. You may add more fuel to help cool the intake charge and cylinder temps. Also, 14.7 is used purely for environmental / emissions reasons around cruise rpm and MAP since leaner mixtures create more NOX emissions but also reduce fuel consumption during cruise

This is the single greatest video I have ever watched. Not only did it have the absolute top tier intelligent explanations from Jay per the usual, but it was also inspirational. It inspired me to hate the feds even more than I already do. In addition. I am a software engineer. The explanation of the read only memory dating back to the first ECU was so perfectly done. The explanation made concepts that most ordinary people will never understand simple enough that they can get the general idea of how it works without knowing all the nitty gritty details as well as how to interpret binary and hexadecimal values. You’re the goat

Funny, i reverse engineered my stock ECU and used an EEPROM to tune it at first ... but it was easier as the original PROM also contained the program, not just the data, so i figured which pin was driving injectors and coils to get a head start. There is another important aspect to the end of tuning, too; sports car engines are becoming more and more pushed in stock form. Most of them already have forged pistons and rods with forced induction, and the engine blocks are built to material fatigue tolerance, so they are lighter and smaller. The days of throwing an insanely strong and heavy lump of iron with forged internals that can withstand triple the original engine power (like toyota did with the mk4 supra) is long gone.

Great video explaining most of the history of tuning

No matter what the government is trying to regulate, whether it’s emissions, gas cans, guns, recreational plants, dog breeds, whatever, the correct answer is NO. We need to declare a 1,000 year moratorium on new laws being passed and let the bastards instead debate on which ones to repeal.

This man's voice; when paired with these topics and the peak emphasis he puts on certain things in a sentence just commands you to listen up and listen closely. 👌👌👌

I love your channel your knowledge is absolute gold

Something that is often misunderstood is that while yes the maker (or more correctly, the rights holder) owns the IP, they do NOT own each individual copy. Each copy of the software is the property of the user that bought the car. This is be long protect in the U.S. by the First Sale Doctrine among others.

I doubt there will ever be a truly un hackable ecu. Your going against 1 the human nature to understand and control things and 2 the amount of professionally taught software engineers that do this stuff for either pay or it’s their hobby. I mean look up almost any device ever that’s somewhat popular, odds are you can find out how to modify the software on the device

And people wonder why I like carbies so much.....hahahaha Fantastic video as always 337 SPEED, the research, delivery and editing is absolutely spectacular. Its a credit to you.

I'm so happy I found your channel!!!

Where i live in Houston, it seems every diesel truck is rolling coal or has a bolt on exhaust etc. Im pro tuning but blowing black smoke everywhere on a daily driven vehicle is excessive.

I've actually noticed a lot more tuners getting CARB EO for their tunes. I do believe recently APR has finally gotten EO for their tunes and even lesser known like 034Motorsport has recently gotten an EO for my car. If the company has the money and patience to plow through the BS redtape, they can get an EO.

Add this to the list of reasons we need right to repair. I should be able to run whatever software I want to on MY car. I don't care if that's a 90's Honda or a Tesla. If the software I'm running is open-source, the EPA can check and make sure I'm not trying to defeat the smog tests. We can still verify that reasonable rules are being followed, but allow freedom to tune to their heart's content

I feel that car enthusiasts will find a new passion in old carb tech.

That corvett tamper override is insane. Remember when you could own things you paid for?

Your videos are literally some of the best explained on RU-vid 🙏 Do a VR6 the German 2jz

This guy always brings the heat with every video. love you man.

I think some high-end companies need to make after-market ECU devices that include the appropriate sensor devices to allow you to keep the vehicle in compliance with emissions standards while tuning it. It would specifically place the limiters to the legal limits, but let you tune anywhere below that point, which would allow you to get substantially higher performance out of the engines. Most notably, since it would be utilizing sensors in the exhaust system to handle the capping, it could bring any other untested aftermarket parts into compliance, barring some extreme cases like non-compliant catalytic converters or fuel additives. While this means one additional expensive component would be needed, all the other components could operate without the high cost of certification themselves, making only one component require certification.

12:37 blud caught me right in the middle of an inhale too, well played

The quote: “it would be disingenuous to think that the cammed zo6 driving around the parking lot is lowering your life exepectency, when you probablly vape” its sooo truem

Another good point to mention for California is newer vehicles do not need to be smogged for the first seven years after you purchase so technically you have free reign for a few years if you want to modify and can always take it back to stock.

That New Edge at the end is a fighter, keeping up with that new Mustang..

The latest trend is to bypass the sensors instead of reprogramming the ECU. The ECU relies on sensor data to do its job. If you feed it with fake data it will do whatever job you like. These sensor bypasses are usually easily installed and removed, thus you can take them out for an inspection and put them back in a couple hours.

Spot on! This is the most logical and straight forward video i've seen so far in this topic. Well done!

Love for 337. This channel is just keeps leveling up.

somehow this man has teached me more about cars than anyone else

Love your videos!

Makes me want to build a car from the ground up with a crate engine. I'm an electrical engineer who does embedded software and I also speak solder. So I'm thinking I would just either get a COTS ECU for a small block or Coyote or do it myself. Interesting that Pappadakis' tuning of the Supra involved fabbing a custom EFI manifold b/c the stock Supra tuning was locked down tight.

Thank you for the introduction to tuners! That says it all. We don’t get enough positive credit for what we do.

These videos are most informative. A toast to excellence in education, Cheers.👍😎👍

There are ECU replacements that are tuner friendly, Holly EFI for one, it's expensive but it'll work if you're really determined to tune an un-tuneable ECU.

The way you narrate your videos is nothing short of perfect. Love the way you explain things! Keep it up!

The detail with these videos is why this is one of the best performance channels here. Tuners pushing the envelope and innovating is why this freedom will persist.

Let's see...to get more fuel you can always piggyback a Bosche CIS distributor pump and injectors, for more air-flow a turbo and exhaust, all that remains is control over spark advance, I imagine you could relocate the crankshaft position sensor.

I love that final point of "the 1% of tuners aren't going to make a difference"

337 Speed dropping another high quality video 🙏🏿

What you said there at 10:20 . My first thought after hearing you say that was, so it sounds like stand alone will become a lot more common, and cheaper. Then hopefully more common means more people learning on there own through forums, videos, or meeting people and asking them, instead of relying on tuners

Loved this video !!

This is why I'm holding on to my 1965 Plymouth Barracuda. Even though it has a 660HP 340 in it the body and engine are before emission testing.

I love your content bro! Easily my favorite channel on yt rn! Keep it up!

Man i forgot half the stuff i wanted to write because i got so hooked by the vid. Explanations on point, visuals fitting, i can hear the voice clear over the nice tune running in background... Now i gotta watch it again! Thanks! lol. 💓 But yeah. Most stuff that is fun and makes sense nowadays is regulated. The thing is it's regulated by crooks that put profit in front of everything else... And emissions from private car owners really are NOT the problem. The industry should be taken more responsible for putting all the dirt out in the environment. Yeah sure we buy the stuff and they even trying to make us fell bad for it, lol. But in the end it's them creating the need for such things. Only because of profit. ..i.. :D Ima keep tuning, 0 f given. 💀 Peace o7

bro i learn on mechanik and i have first year over, thats mean i go yet to next year and iam very happy for your content of engines thx bro , I can't get enough of the information I've learned at the moment. sorry for my english

Excellent video. Great research.

I'mma still tune. IMMA BE AN OUTLAW.

My carbureted 65 Mustang is now the future. The irony.

The rolling coal thing it what puts modifying in the publics eyes 😂😂

The EPA is really biting the wrong crowd E85 is a cleaner fuel compared to gasoline and tuning companies have been promoting it engines aren’t going away the tuning companies could make mods so people can use cleaner fuels like e85 or hydrogen so people can continue to use their cars
