It is not actually safety these german manufacturers have in mind when limit top speed at 155 mph. The main reason is to reduce cost. A car that can run over that speed will require different brakes, tyres, suspension, aerodynamics and so on. If the engineers let these cars run free, some might cross the 200 mph barrier and then, everything will have to be reengineered and it may compromise the whole Project and make it inviable.

I am a big fan of your videos being an engineer myself. I like this one because of the pragmatic approach of even if it is illegal should not prevent people getting the full(er) picture of what's there in terms of software limits in their cars. I think what should be a bit more included (even though it was for a half sentence) is the trade-off one makes with tampering their ECU parameters. So I do not know how well they do around where you live but garages in London who claim to know this kind of stuff and flash your car for you actually don't get this all that well in the end. I have seen some codes for my BMW engine that some of those guys have done(not to my car, someone else's but the same engine regardless). I have checked some parameters they were tweaking and some are merely taking limits off and pushing air-fuel to some constant instead of an adaptive number etc. I think what those poor guys whose car will get half of its lifetime taken by this don't realise is exactly this kind of trade-off. There are 2 reasons an engine is tuned the way it was in the factory: - longevity/fuel-economy/efficiency - because they had a more expensive model with the performance option using ALMOST the same components In my BMW there is a mix of the 2: There are smaller components in the lower models than in mine in terms of CAT, EGR, and cooling but it is the same engine block, electronics and ECU just different injector nozzles and software parameters. So what crazy people do is slap in the injectors of the more performant model, load in its software and then enjoying the next 50k miles because after that your engine will be wasted along with the turbocharger. Is it worth it really? Well math says it is not. Buy the performance model if you need more performance. A BMW is used sensibly and general care can go up to a staggering 300k miles without you having to touch the engine. By that time you will have replaced 3-4 sets of suspension components underneath it in this lovely country of speedbumps and potholes :) Sensibly I would only recommend tuning the ECU as the engine ages and timing code might be needing adjustment. As the components wear timing might become a tiny bit off. But then again the original BMW software is pretty good with their sensors of camshaft, the lambda, and the air-flow sensor to detect and adjust automatically. It comes down to a lot of knowledge and understanding the original approach of the manufacturer to tuning to sensibly override the factory settings. Most of that information is proprietary and it may never have been documented even. I believe while you may easily change these(a cable for usb to OBD2 is 5-6 dollars on ebay) I would think twice before just trusting John Doe's garage to tamper with mine. I'd rather trust a manufacturer's judgement(who puts an engine on a test pad and runs it for ridiculous hours after a code change and then disassembles if to have a look at the components when they develop the model) than that of some random guy who self-learned how to read and write some of these values. I think people should buy and pay for the brand and model they trust to have a good configuration on the get-go. DISCLAIMER: I hereby acknowledge that there may be people at random garages who understand the full gravity of tampering with ecu settings but they are incredibly rare.

Wanted to jump in on this here... Regarding the A/F ratios... Manufacturers don't tune their vehicle lean. In cruise? Maybe in the 90's (e.g. Civic HX). Nowadays, lean burn won't pass emissions testing. That's the purpose of the narrowband O2 sensor - it tells the ECU whether to increase or decrease fuel delivery in order to precisely hit stoichiometric AFR's. When running lean under load, you'll experience knock as well. The 12.5:1 is also for naturally aspirated cars; Forced induction cars are typically tuned to around 11.5:1 or so. My point is that a flash tune doesn't richen your AFR's... it leans them out. Factory tuned ECU's are usually around 10.5:1 to prevent pre-ignition from higher cylinder temps (and because the fuel burns faster when the AFR is leaner, causing it to completely combust prior to the piston reaching the top of its stroke). However, just like with an AFR that's too lean, an AFR that is too rich will also rob power. This is why when you retune a car, it typically says to use premium gas. Higher octane fuels have more stable burn characteristics, and also burn slower.

So, if you tune your ECU for more power, your fuel efficiency will go down and vice versa? Cause I've a seen a lot of these ads lately where they say if you tune your ecu you'll get like 20 bhp+ and 10mpg+ etc... and I am just wondering, if this was the case, why wouldn't factory cars come pre tuned at these settings? This is false advertising, am I right?
@EngineeringExplained
@EngineeringExplained 9 лет назад
You're not going to get dramatically better gas mileage, correct. But as is apparent with the latest VW scandal, engine tuning can allow for more power and more efficiency, for example by running on less EGR (granted, it's illegal and shouldn't be done).
@TheIcekake
@TheIcekake 9 лет назад

@RHBTurbochargers
@RHBTurbochargers 8 лет назад
+Ketho Seyie You can always make a car more efficient off load and have more power on load. Manufacturers typically run cars at stoich (14.7) afr for best emissions. Running your car at a afr of near 16 will drastically improve gas mileage. Manufacturers don't do this because this produces more hydrocarbons and that is bad for the environment. Keep in mind that you need to adjust timing and injection timing to make the leaner mixture create power without pre ingition or detonation.
@OminousCamaro
@OminousCamaro 8 лет назад
+Ketho Seyie Your ECU can be flashed to deliver more fuel at higher RPMs and deliver less fuel at lower RPMs at cruising speeds. This is usually done on stock powertrain. This does help achieve more power top end and save fuel when you're not mashing on the accelerator. So, in essence, yes there are tuners that can give you better gas efficiency and more power just not at the same time. For example, I have a 2010 Camaro I bought a handheld tuner from Diablosport. There is a tune that gives me better gas mileage at cruising speeds and more HP when I'm "balls to the wall". I achieved between 27-29 mpg on the highway with that tune (my car has the LS3 and 6-speed manual). There was a slight power difference at higher RPMs. Before I upgraded to Long Tube headers, high flow cats, and Axle back exhaust I was getting around 21mph combined. After the upgrade I get around 17-18mpg combined. In retrospect, adding power equates to less mpg. However you can maximize the efficiency and mpg with a conservative tune when you add performance upgrades instead of adding more fuel and that all depends on what your Fuel/Air ratio is when it is tuned. Professional tuners prefer to run a performance engine slightly richer to eliminate the chances of detonation. The reason behind that is the rich fuel/air mixture reduces the combustion temperature. With the reduced combustion temperature your fuel/air mixture is less likely to detonate outside of the combustion chamber which is critical especially in modern day port injected vehicles. A leaner fuel/air mixture yields a higher combustion temperature which would cause fuel to ignite to early and cause damage to your engine. Other factors do apply such as octane rating and ignition timing which also can cause early detonation, engine knock and/or pinging.

@NabilChouchany
@NabilChouchany 8 лет назад
Great simplified explanation as always! PS: the richer mixture is not "better" for the catalytic converter, it just provides more power (it might be good for the combustion chamber: piston, cylinder etc..) as it decreases the heat a bit). Even factory programs allow a rich mixture when you're flooring the pedal, to increase power, the mixture would have a ratio of .85 to .9

I wish there were more company's like the Cobb access port where you can simply plug it in and adjust everything. When my supra was stock with the factory ecu, there aren't many options for obd port tuners. But eventually when i went single turbo i installed a standalone ecu and its worlds different than the factory one.

It's by mass, so it operates under the assumption that oxygen and nitrogen densities are as described in this video, which are at atmospheric. But you can change the pressure without altering the ratio, if the percentages of the gases remains the same.
@jlgroovetek
@jlgroovetek 10 лет назад
I guess there's only so much detail you can provide in 5 minutes, but one important thing to note for people interested in chip tuning and watching this video is that you can still maintain lean AF ratios for fuel economy under idle/cruising scenarios but enrich the mixture to 12.5:1 for instance only when you want the power. Just because manufacturers are seeking good fuel economy doesn't mean they don't run their high load maps very rich. In fact, they will often configure their exhaust gas temperature regulation model that can result in a 12:1 or sometimes even richer running condition, under high load scenarios for engine protection. So in these cases you can make more power by leaning out the fuel map or temperature modelling compared to stock to make more power. Lastly, not all cars respond best or make peak power at 12.5:1. Some may prefer lower than this, but several modern direct injection engines (ie. Volkswagen FSI) exhibit better mixture/atomisation and therefore do not require an overly rich mixture to make peak power.

14.7 is stoichiometric (ideal), I have a video "air fuel ratios" if you'd like to know where that number comes from. 11.3 could be the case for many turbod cars, but it's certainly a rich mixture - for maximum power though this is fine.

Yes, lowering the A/F ratio will result in more smoke. Modern emissions equipment can basically eliminate this on diesels, but it can be restrictive so some people remove it. They care less for Earth, and more for loud noises and fast speeds. I applaud those who are opposite. I myself struggle with the dilemma of wanting an amazingly quick car that's also efficient. For the time being, the Integra meets the "effecient" part.

Maybe this has already been mentioned in the over 500 comments posted so far, but here goes. It is indeed tempting to consider chip-tuning. But if your car is still under warranty and the engine fails they will check if the software is original or tuned. Furthermore, in some countries the car is taxed by horsepower so if they find out that your car has more power than it should have you can get a bill to pay tax for the extra horsepower.

Also with these set ups you can sometimes eliminate eliminate efficiency robbing components such as the old vane meter (flappy door MAF) sensor.

It's possible to safely lean out afr's slightly across the entire rpm range in many cases and observe a noticeable increase in fuel economy.

Well, the powertrain can be able to power the car to 200 mph, but to sell a car that goes 200 they would need to design 200mph brakes, 200mph suspension, 200 mph tires and wheels, and so on. Limiting to 155mph makes all components to designed to 155mph, being then cheaper and simpler, therefore not related to regulation.

I know a lot of the ECU upgrades for Saabs ratchet up the turbocharger pressure. Of course, there's a limit to how much cooling the stock intercooler can provide, but I wonder if the intercooler was engineered to perform under a variety of environmental conditions -- including hot desert climates -- so maybe, living in the Northeast US, I can feel comfortable pushing it a bit further.

For a cat. to work it needs to get both lean and richt mixtures so the ECU makes sure the mixture is adjusted during driving. But i'm also pretty sure that when you floor it the ECU calculates for a rich mixture.

Correct, they are limited for safety (but capable of going faster). Sorry for the misunderstanding!

quick question. you have a lot of knowledge about how things work and have done a good job at explaining. but are you hands on and have you ever build a car or motor. just curious.

Also you could increase the horse power changing the turbo settings, with this normally you get better fuel economy. In diesel engines the new HP, torque and fuel economy are amazing. The disadvantages are that the turbo and engine will break sooner.

Another great video man... Keep em' coming!! If you haven't yet PLEASE do a video about suspensions with an emphasis on the addition of sway bars, specifically how they can potentially dramatically effect the handling of front/all/rear wheel drive cars from the factory set up.

As someone who tunes car 14.7 for ideal seems a bit leaning towards rich. The ideal AFR is 13.5 for a NA engine, 11.3 for a Turbo, and 14.7 for a supercharger. I'm not saying you're wrong and if you have a reasoning for it, i'd love to hear it.

Thanks for the quick answer! I have to say that I LOVE your channel. It's really amazing how easily you can explain all kind of stuff other people try to explain to (without succes). Could you add some video explaining how EGR valve works and whats the benefit/consequence of removing it? (I have read something about it and some people recommend to remove it, others not) When you have time of course, thanks for all your videos, keep it up!

depends what you're using your engine for. Flame propagation of diesel is much slower than gasoline..so the red line is much lower on diesel engines..with a low red line it is difficult to get a high power to weight ratio--which is exactly what you want in a race engine.

I dont know if you could respond to this but im going to go for it. Im 17 and i bought my first mustang its a 3.8l V6. And i get around 800$ a months how often would you recommend buying performance parts, if i didint care id spend about all off it and just pay the bills and car upgrades lol. But im sure you've had youre fair share of cars and i just wanted an opinion since i always watch all these performace parts videos that you put out. Keep up the the good work. Thanks
@EngineeringExplained
@EngineeringExplained 9 лет назад
Franjluna74 Well I'll probably sound like a dad but I don't spend much on parts, at all. Depending on what your goals are, many of the investments are poor (not to mention it will not increase the value of your car). When I was 17 I saved all of my money, and didn't do a thing to my Integra. It's a great car as is. :)

Thats kinda sad. My 4x4 explorer sport 4.0 will beat your mustang at any race aside from track. Pushing around 300hp at the wheels in 4x4. 4.3l stroker crank,ported and polished the heads,ecu and timing tune,and a 3.5psi supercharger. (I can switch a pulley and go to 5.5lbs,or 8.5lbs) My trucks mods weren't put in for racing either. With locking differentials (front,rear and center), 4.10:1 finals,transmission rebuilt with a heavy duty kit and a shift kit,transfer case rebuilt to heavy duty specs,dual caliper brakes all around and still on 17" rims. (Stock tire size,aftermarket rims)...designed to tow,and to do it in any scenario. (5000lbs max offroad, 9,000lbs highway,11k city (less than 15 miles) 0-60 in 5.8seconds quarter mile in 15. Top speed is unchanged from factory. 117.9 tops out,5500rpm in 3rd gear. Rev limit moved to 6750rpm. (Mainly for 4-lo to have a bit better acceleration through shifting.) My advise would be to start off simple. Get a dyno tune and a timing tune. Then before you get any performance upgrade make sure the transmission is up to the task,the motor mounts,head gaskets,any thing that could fail pretty much. From stock the first thing I did was a twin opening throttle body that gained me about 6hp and 5lb-ft,was mostly done becuase I replaced the stock one after it failed,and I wanted a bit more overall air flow for the stroker crank to shine. After the TB I rebuilt the transmission (wasn't in any state of disarray when I did it) After the transmission I put a high stall torque converter in,and rebuilt the transfer case. After that replaced the axles to something much stronger,new driveshafts and heavy duty ujoints and CV joints. Then we regeared it from 3.27 to 4.10,that was the biggest feel of the pants change,especially at highway speeds. After that we put the stroker crank in,ported and polished the heads and re tuned it again for more torque from 2500-5500rpms. (Gained about 15lbs through the curve from the tune alone,and about 25 from the new crank) After that we replaced the pistons and connecting rods with heavy duty performance ones. Raised the compression ever so slightly from stock 9.7:1 to 10:1,and started preparation for the supercharger. (Eaton m112,dont remember what year) Performance high flow fuel injectors,high flow fuel pump,NGK Iridium spark plugs and a air to water intercooler had to be fabbed up. (Planned maximum boost is 10psi with a drop to 9.2-9.5:1 compression) Supercharger installed,current pulley installed will net me 5.5lbs of boost but we purge it to 3.5psi,really aiming at the low rpm torque more than anything else. I have a pair of garret gt1549 billet rebuilt turbochargers I plan on using in the future i n conjunction with the supercharger. (Max boost then would be 15psi) But I got lucky and I live less than half a mile away from a gas station that sells 110 octane fuel. Key advise no matter what route you go for adding performance to a car, is to simply do it right. Dont skimp on the little things becuase when they fail you have much larger issues. (Like leaning out at high rpms with a supercharger melting your pistons becuase your running 7psi of boost and still using stock injectors and a stock fuel pump,but you tuned it and raised the rev limiter by +1200rpms. *note* My truck also has a heavy duty copper radiator,and heavy duty copper transmission cooler installed,running alongside the stock ones.

there is an ability to use a hydrogen gaz instead of diesel or gasoline but i think the hydrogen (H2) doesn't have a powerful energy link between two atoms of hydrogen ,as you know, when the H2 is breathe to the intake manifold in a pressure of (1atm). in fact, I think that there is an ability to compress the H2 on a stainless steel bottle like the nitrous oxide for more power, you named... :)

ECUs are cool! Would be much fun to repurpose an old one with all that analogue and digital fun stuff going on within! In a really modern ECU what kind of main CPU is inside? Wouldn't it be nice to find an 80386 or Motorola 68040 inside but I bet they use special chips using ARM cores now.
