Car tuning is a generalized term referring to the act of improving the performance or appearance of a vehicle. For actual 'tuning' in the sense of automobiles or vehicles, see engine tuning. Most vehicles leave the factory set up for an average driver's expectations and conditions, tuning on the other hand, has become a way to personalize the characteristics of a vehicle to the owner's preference. Cars may be altered to provide better fuel economy, produce more power, or to provide better handling.

Car tuning is related to auto racing, although most performance cars never compete. Tuned cars are built for the pleasure of owning and driving. Exterior modifications include changing the aerodynamic characteristics of the vehicle via side skirts, front and rear bumpers, spoilers, splitters, air vents and light weight wheels.

Origin

In the 1970s and 80s, many Japanese performance cars were never exported outside the Japanese domestic market. In the late 1980s and early 1990s, grey imports of Japanese performance cars, such as the Nissan Skyline^[1][1][2][3], began to be privately imported into Western Europe and North America. In the United States, this was in direct contrast to the domestic car production around the same time, where there was a very small performance aftermarket for domestic compact and economy cars; the focus was instead on sporty cars such as the Ford Mustang and Chevrolet Corvette, or on classic muscle cars.

Because of their light weight and the increasing availability of low-cost tuning equipment, economy and compact cars exhibit high performance at a low cost in comparison to dedicated sports cars. As professional sporting and racing with such vehicles increased, so did recreational use of these vehicles. Drivers with little or no automotive, mechanical, or racing experience would modify their vehicles to emulate the more impressive versions of racing vehicles, with mixed results.

Areas of modification

The essence of modification of a tuner car is an attempt to extract the greatest possible performance—or the appearance of high performance—from the base motor vehicle through the addition, alteration or outright replacement of parts. Although this largely involves modifying the engine and management systems of the vehicle to increase the power output, additional changes are often required to allow the vehicle to handle this power, including stiffened suspension, widened tires, better brakes, improved steering and transmission modifications such as the installation of a short shifter. Although largely invisible from outside the vehicle, certain modifications such as low profile tires, altered suspension, and the addition of spoilers can change the overall appearance of the car.

Audio

Audio is a term used to describe the sound or video system fitted in the vehicle. A stock audio system refers to one that was specified by the manufacturer when the vehicle was built in the factory. A custom audio installation can involve anything from the upgrade of the radio to a full-blown customization based around the audio equipment. Events are held where entrants compete for the loudest, highest quality reception or most innovative sound systems.

A misconception in mainstream society is that enhanced audio systems play a major role in tuning. Modern tuners usually do not have elaborate sound systems. The focus of tuning is performance based.

Interior

All cars competing in each class must adhere to a strict set of regulations. As in some well known racing events, like NASCAR and NHRA, sanctioned events often require a minimum vehicle weight. In such cases the interior is stripped and lead weights or similar are added to meet that requirement.

Along with weight requirements, safety requirements are present . Requirements differ for different classes. Roll cages, fire extinguishers, reinforced bucket seats, seat harnesses, and the like are some of the required safety modifications. Roll cages may be difficult to install when the original equipment interior is present.

A common misconception is that a tuner will install such equipment as flashy lights, TV screens and similar items to enhance the appearance of their car. In reality, though, improved performance is the fundamental goal of tuning. Because form often follows function, performance modifications may often improve the appearance of tuner cars. Some tuners will have 'gutted' interiors. Some even go as far as to not have a sound system or even an A/C.

Engine tuning

Engine tuning is the process of modifying the operating characteristics of an engine. In a typical engine set-up, there are various mechanical and electronic elements such as the intake manifold, spark plugs, Mass air flow/ Volume air flow, etc. Modern engines employ the use of an ECM to provide the best balance between performance and emissions. Via the OBD communications protocol, the electronically controlled aspects of the engine can be modified in the process known as 'mapping'. Mapping can either be preformed by changing the software within the ECU (chip tuning via firmware modification), or by provide false data via plug-in hardware ( piggybacking). Mechanical components can also be replaced, such as turbochargers or superchargers.

Other standalone engine management systems are available. These systems replace the factory computer with one that is user programmable.

Poorly executed modifications can have a detrimental effect on performance as well as mechanical and electronic components. An example would be the use of an air compressor such as as a turbocharger to increase the volume of air used in power stroke of the otto cycle. In a typical chemical reaction, the air-fuel ratio must be a minimum of 14:1 (see Stoichiometry). If higher ratios are used, higher pressures and temperatures are observed in the cylinders. Depending upon the build of the engine, such operating parameters can lead to premature failure such as warped cylinder heads and walls (temperature related), cracked connecting rods and crankshafts (excessive torque applied), engine seizing and blowouts.

Suspension tuning

Suspension tuning involves modifying the springs, shock absorbers, swaybars, and other related components of a vehicle. Shorter springs offer greater stiffness and a lower center of gravity at the cost of proper suspension geometry. Stiffer shock absorbers improve the dynamic weight shifting during cornering and normally have shorter internals to stop them from bottoming out when shorter springs are used. Stiffer sway bars reduce body roll during cornering, thus improving the grip that the tires have on the surface by reducing suspension geometry changes caused by roll; this also improves handling response due to faster weight shifting (similar to stiffer springs.) The danger with overly stiff swaybars is the lifing of the inner wheel, which reduces its traction. Loss of traction less likely with softer bars. Other components that are sometimes added are strut bars, which improve the body stiffness and help better maintain the proper suspension geometry during cornering. On some cars certain braces, anti-roll bars, etc., can be retrofitted to base model cars from sports models.

For offroad vehicles, the emphasis is on lengthening the suspension travel and installing larger tires to increase ground clearance.

These suspension modifications are in contrast to Lowriders with hydraulic or pneumatic suspensions. Lowriders use another type of suspension tuning in which the height of each individual wheel can be rapidly adjusted by a system of rams which, in some cases, makes it possible to 'bounce' the wheels completely clear of the ground.

Body tuning

Body tuning involves adding or modifying spoilers and a body kit in order to improve the aerodynamic performance of a vehicle. Through the generation of downforce, cornering speeds and tire adhesion can be improved, often at the expense of increased drag. To lighten the vehicle, bodywork components such as hoods and rear view mirrors may be replaced with lighter weight components.

Often, body modifications are done mainly to improve a vehicle's appearance, as in the case of non-functioning scoops, spoilers, wide arches or other aesthetic modification. Aftermarket spoilers or body kits rarely improve a car's performance. The majority, in fact, add weight and increase the drag coefficient of the vehicle, thus reducing its overall performance. These are called Rice Burners.

Tuners know what down force means. They will have modifications such as air canards and rear diffusers. These cars may seem flashy sometimes but, their main goal is performance. The tuner will not use cheap inexpensive tuning components. They only use name brands. When it comes to speed and control, money does not mean that much.

Increasing the wheel track width through spacers and wide body kits enhance the cars cornering ability. Lowering the center of gravity via suspension modifications is another aim of body tuning. Often, suspension tuners unfamiliar with spring dynamics will cut stock springs, producing a soft, bouncy ride. It is also common to lower the car too far beyond the optimal center of gravity purely for appearance.

Competition cars may have light weight windows, or the windows may be completely removed, as auto glass adds significant weight. Plastic windows are much more vulnerable to scratches which reduces service life.

Tires

Tires have large effects on a car's behavior and are replaced periodically, therefore tire selection is a very cost effective way to personalize an automobile. Choices include tires for various weather and road conditions, different sizes and various compromises between cost, grip, service life, rolling resistance, handling and ride comfort.

Detuning

Detuning refers to returning a modified car to its original factory status. The term detuning can also refer to the reduction of performance in a particular area of tuning. For example, a car may be 'detuned' to allow increased traction where the track grip is not sufficient to handle the increased power of the tuned engine.

Styles of modification

Modified cars can be significantly different from their stock counterparts. A common factor among owners/modifiers is to emulate the visual and/or performance characteristics of established styles and design principles. Sometimes these similarities are unintentional. Some of the many different styles and visual influences to car modification are:

• Rat style: The characteristics of the rat rod style of hot rod and custom cars, imitating the 'unfinished' appearance of some hot rods in the 40s, 50s and 60s.
• Hot rod style largely consists of period specific vehicles, components and finishes to reproduce characteristics of early hot rods from the 1930s and 1940s. This style may also include the associated styles of Street Rods and Custom cars.
• Modern styles include the recently established modification styles such as the Import scene, Lowriders, European(Euro-style), DUB, Cal Look; most of which are largely visually oriented.
• Cultural/media styles: The characteristics specific to cultures, stereotypes and media, such as Boy racers and film specific cars. The Fast and the Furious (film series) provides an often emulated modification style.
• Production car styles, in which he characteristics of current-model and luxury cars, Sports cars, Supercars and Muscle cars are emulated, largely with the intent of improving or updating a vehicles appearance and/or technology to current market preferences.
• Purpose built or racing car styles such as Touring car racing, Rallying, Drifting (motorsport) and Drag racing.
• Sleepers: This is where a car owner will put every effort into performance and try to keep the car looking standard, usually in order to not raise suspicion.

Terms

'Streeted' or 'Tuner Cars' are typically Japanese vehicles, such as a Honda Civic, Mitsubishi Lancer, Toyota Supra, Nissan 180SX and Nissan 240SX, Mazda Protegé that have been lightly or heavily modified. In response to highly tuned and customized vehicles and the rise of rallying in the late 90's to early 2000's, Mitsubishi and Subaru released the Lancer Evolution and Impreza WRX STi respectively and are most commonly modified with more expensive components due to their already impressive specs. The most popular modifications include suspension upgrades, exhaust systems, and turbos.

Legal requirements

Many countries or municipalities have legal requirements which govern vehicle modifications. For example, all vehicles in Victoria, Australia, must conform to construction standards to ensure vehicle safety.^[4] There are also restrictions for P Plate drivers which can prevent young drivers from driving modified vehicles.^[5]

In the United Kingdom, Australia and the Netherlands it is illegal for any car to have blue lights which are reserved for emergency vehicles.

In Scotland, Germany and Denmark, it is illegal for any car to have neon underlights on a car which may distract other drivers. In the Netherlands neon lights are allowed under the car, but only when the car is on display. The lights have to be switched off if the car is on a public road. There is some misunderstanding amongst police officers in the U.K as to the legality of under body neons^{[citation needed]}.

Recently, Belgium issued a new law which requires that bodykit parts need to be approved for safety.

In the United States, many of the laws governing car modification are determined at state level. These should be reviewed before any modifications are undertaken.

Sanctioning organizations

Many organizations involved in competitive motorsports establish safety guidelines that far exceed legal requirements placed on street legal vehicles. The NHRA, IHRA and SOLO programs all require that vehicles pass inspection to ensure that all regulations are being complied with.

Clubs

A big part of car modifications are car clubs or groups. These car clubs are composed of many different types of car enthusiast, making up the culture of the car 'scene.' Usually these car clubs will meet weekly at a specific location and at a specific time. These meets are usually pretty friendly and open to any car enthusiast. Sometimes these meets attract the attention of the local police force but as long as the people at the meet do not do anything they are not supposed to the police will leave everyone alone. Most of these car clubs are composed of just a few friends who have modified their cars to the way they like them and some clubs go out and beyond to try and get sponsorships from large aftermarket companies to support their car tuning. Clubs often attend national shows throughout the country. There are thought to be over 100 car clubs in the UK and probably more than double that amount in the United States where the popular film 'The Fast and the Furious' have impacted the car 'scene' the most.

Popular culture

It is important to note the significance that car tuning has had on popular culture. Today modified cars can be seen in many different places around the world, each car being more and more unique to the other. Whether Japanese, American or European, car tuning can be seen through all walks of life, rich or poor, any car enthusiast will modify their car to their liking. Speed tuned cars feature in various movies and in songs such as Hot Rod Lincoln. Tuned cars and custom cars are depicted in film, such as those featured in The Fast and the Furious (film series). Today many film and music artist have incorporated modified cars in their media, depicting fast, tuned cars in a movie or TV commercial or a tuned car in a music video.

So you’ve got your antenna setup and plugged into the back of your television set only to find your auto scan not finding channels, or at least the channels you were expecting. If this is happening to you keep reading! In this article we are going to take a look at what the likely causes of this could be.

Why Is Auto Scan Not Finding Channels?

There could be several reasons why your auto scan is not finding channels. To start, let’s make sure that you are selecting the right input mode on your television set.

Typically, this will be found under your Menu –> Channels –> Auto Scan. Of course not all television set manufacture menus are the same, so yours may vary from this slightly. You can see in the image below that my TV refers to it as “Auto Channel Search”. If yours is called something different, simply consult your user manual to see the steps your are supposed to take to get here.

Warning

Governments and ISPs across the world monitor their users’ online activities. If found streaming copyright content, you could get into serious legal trouble. Currently, your IP 2a02:c7f:1650:3e00:6033:2064:c3b:fc4d is visible to everyone. I strongly recommend that you get the best VPN for streaming and hide your identity so that your entertainment doesn’t take a turn for the worst.

Here are the reasons why you must use a VPN all the time.

I personally use and recommend you use one of ExpressVPN, NordVPN, IPVanish or PureVPN. They are the fastest and most secure VPNs in the industry.

Once you’re in the “Auto Scan” menu there should be an option to select either “Cable” or “Antenna”. Be sure you are choosing “Antenna” or some variation of this ( I have seen it listed as DTV). This will start the Auto Scan procedure.

If after the scanning process is complete your television auto scan not finding channels persists, it’s time to start troubleshooting. Here are some things we are going to need to check:

• Your TV Tuner is functional – it may be helpful to try a different TV if this is an option to ensure your TV’s digital tuner card is not the issue. This is as simple as plugging your coax cable into a different TV and running the auto scan on that.
• Your antenna cabling is not faulty – we need to make sure that you are getting a signal out of your coax cable. More on this later.
• Your antenna is properly aligned – obviously we will need to make sure your antenna is pointing in the direction of the broadcast towers in your area. Below will be some helpful tips to ensure this is the case.
• Your antenna has sufficient range – this is going to be another important piece of the puzzle to ensure you are able to pull in the appropriate over-the-air (OTA) signals in your area.
• Ensure proper noise mitigation – A noise margin greater than 0 is required at your tuner to display a channel on your TV set.

Let’s look a little closer at each one of these items to try to figure out why your auto scan not finding channels.

Check If You TV Tuner Is Functional

The first thing we should probably try to diagnose is whether your television sets TV Tuner is functioning. I should point out that if your television was made before 2009 it likely has an analog tuner in it. If so this is likely the reason for your television auto scan not finding channels.

If indeed your TV is pre-2009, you are going to need a converter box such as this inexpensive iDOO ATSC Analog-Digital Converter Box on Amazon. With this box you can conveniently convert the over-the-air (OTA) digital broadcast received from your antenna (not included) to your analog TV, digital TV, projector, computer monitor, smart TV, HDTV, LED TV, LCD monitor,etc.

Okay, assuming your television set was made in the last 10 years or so, you should have a digital tuner installed in your TV. That means it’s time to try something else. As mentioned, probably the easiest thing to try is to plug in the coax cable coming from your antenna into a different TV. Admittedly, this can be easier said than done, however, you can split your antenna signal using an Antenna TV Splitter to a room where you have another TV to try.

If plugging your antenna’s coax into another TV is not an option for you then you may want to look at investing in the KING SL1000 SureLock TV Antenna Signal Meter. This meter offers a fool-proof way to locate the strongest available TV signal(s) no matter where you are. If your TV antenna can receive the signal, the SureLock SL1000 can help you point your antenna to maximize it!

Check Your Antenna Cable Is Not Faulty

If the signal meter above is a little out of your price range or you happen to have a digital multi-meter hanging around your house, you can use it to check to see if you have a signal. Let’s do a check to ensure this is not the reason for your television auto scan not finding channels.

Just like any radio transmission your digital antenna receives radio signals that is transmitted via small electrical impulses to your television tuner. This means that you can use an electrical multi-meter to test whether or not a signal is traveling down your coax cable. If there is a problem with your cabling, such as a cut or short in the wire, this will cause the signal to be disrupted.

In addition, if the antenna is not properly grounded, the signal can pick up interference from the electrical potential of the antenna itself. If you are interested in How To Properly Ground A TV Antenna, be sure to check out the article.

Let’s perform a couple of checks using your digital multi-meter to ensure your coax cable is good.

1. Set your multi-meter to measure ohms, which is represented by the “Ω” symbol.
2. Remove the antenna cable from your television set.
3. Touch one lead of the multi-meter to the metal part of the connector and touch the other lead to the metal “core” or “stinger”. The ohm reading should be infinite.
4. Now short one end of your antenna cables metal “core” or “stinger” to the coax connector. On the “un-shorted” end touch one lead on the “stinger” and the other lead on the coax connector. The ohm reading should be zero.

Rather see it in a video. Check out the YouTube video below that will walk you through how to test your antenna coax cable.

Make Sure Your Antenna Is Properly Aligned

Direction, direction, direction! Perhaps one of the most important aspects of any antenna installation. This could be the reason your television auto scan not finding channels. What you need to do is figure out which channels are available to you and in which direction the TV broadcast towers are located. You can use an online location tool such as TVFool.com or check out our very own TV Station Locator

This YouTube video will walk you through everything you need to know when using our tool. It will show you how to find TV stations available in your area and in which direction the TV towers are located.

You will need a compass or at least a smart-phone compass app. Once you use our TV Station Locator tool and have your bearings, head to your antenna and rotate it so it is aligned in the direction of your broadcast towers. If your antenna is on a roof you may want to have someone at your TV end to help with the fine tuning.

Auto Tuning Meaning In Hindi

Alternatively, if you’ve been reading other articles on this site you will know that must “cord-cutting” enthusiasts rarely bring their antenna signal directly into their television set. Rather, they stream their antenna signals indirectly to their smart TVs, tablets, phones, Media Streaming boxes by way of a network tuner device.

The tuner devices I own can be purchased directly on Amazon and are called SiliconDust HDHomeRun EXTEND (2-Tuner) tuners. These devices are awesome!

If you get yourself one of these network tuners then your task of aligning for the best signal strength becomes much easier via one of the free smart-phone apps available on the Google Playstore. You can see in the image below I get real-time feedback of my antenna signal strength for a specific channel all while standing on my roof at the antenna…cool!

Check Your Antenna Has The Required Range

It’s important to understand that no one antenna or antenna type will deliver excellent TV reception in every location. The main factors determining reception are the distance and direction from the TV station transmitters to your home.

The transmitter’s power and the height of its tower also matter. This alone could be the reason for your auto scan not finding channels. Be sure to check out my article how high should you mount a TV antenna.

If you live within a few miles of the broadcast tower, and the signal path is relatively unobstructed, you may be able to get solid reception using a small indoor antenna. However, as you move farther away, getting usable signal strength becomes trickier. This is where careful antenna selection and installation become essential.

First, it’s probably a good idea to discuss the two broad categories of TV antennas that are out there so you can understand which category your specific antenna fits into. The two classes are omnidirectional and unidirectional, so let’s take a closer look at both.

OmniDirectional are antennas that will receive a signal from all directions because they offer a 360 degree field. So if you have one of these types of antennas there is really no need to “point it” in any specific direction. In this case if you are not getting the results you think you should be getting your only option is going to be to find a better location on your house or property.

If you’re in the market for a good omnidirectional antenna I highly recommend the Mohu Sky 60 TV Antenna.

UniDirectional antennas have a much narrower beam width, typically between 25 and 35 degrees. These types of antennas are much more resilient to noise and are ideal when your broadcast towers are clustered together in one general direction or area. It is important to note that TV signal transmission is “line of sight.” Getting reliable reception beyond the curvature of the earth (roughly 70 miles) is difficult. Mountains or tall buildings between the broadcast tower(s) and your home can also cause reception problems. So, the first step is to locate the transmitters for your local stations and point your antenna that way.

Meaning Of Auto-tuning In Hindi 2017

I personally use two unidirectional antennas in my setup. If you’re interested in checking out my current system check out this article The Best HDTV Antenna Setup Right Now. If you do, you will see that I am using the Channel Master CM-4228HD HDTV Antenna, I highly recommend this antenna for both affordability and quality.

Ensure Proper Noise Mitigation

The last thing I want to discuss is noise, the major causes of it and how to reduce or mitigate it. Any digital signal is going to be received by your antenna and ultimately your tuner with a finite amount of power. One of the easier ways to quantify this power is noise margin. The noise margin, given in decibels (dB), is the amount of signal noise allowable before the signal can no longer be received.

Noise can come from many sources, including any obstacles or interference encountered between your antenna and the broadcast tower. Other sources of noise can be that caused by splitters, the tuner you’re plugging into, and the coaxial cable itself.

This is why it is important to use high quality components and cabling. For splitters I recommend ANTOP Low-loss 3 Way Coaxial Splitter for TV Antenna or equivalent for its low-loss insertion. For coax cable you want to use a high quality RG6 such as Mediabridge Broadband Coaxial Cable.

Also, if the antenna is not properly grounded, the signal can pick up interference from the electrical potential of the antenna itself. If you are interested in How To Properly Ground A TV Antenna, be sure to check out the article.
