People who use UTVs for Powersports and racing are always on the lookout for improving their vehicle’s performance. One of the best ways you can do that is through the process of dyno tuning. By increasing the horsepower, it can enable your UTV engine to run at its highest power. The dyno tuning cost is not on the inexpensive side, but it can make a significant difference in your UTV’s drivability and fuel economy.

What is Dyno Tuning?

Dyno tuning is a process of measuring the torque and rotational speed of the UTV engine to find out its exact amount of power. You can take the UTV for tuning to a shop with an industry-standard measuring device known as a dynamometer (dyno). They will roll out the UTV for testing on a dyno testing platform.

Along with checking the engine’s output, the testing can also measure its air-fuel mixture. The mechanic will use the test readings for tuning the UTV engine to the settings that deliver maximum results.

Additionally, the testing can help adjust the fuel delivery and valve timing to increase the engine efficiency. If there are any gas mileage or engine starting issues, the dyno machine can identify these problems and you can get those repairs done as soon as possible. That can ease the wear and tear on the UTV engine, extend its lifespan, and enhance the driving experience.

Dyno Tuning Frequently Asked Questions

What is a chassis dynamometer?

A chassis dynamometer is a measuring machine with a rolling platform on which you can drive your UTV. It then carries out various driving simulations to test the UTV engine. For instance, it might simulate driving the UTV in different situations, such as on a regular level road, uphill, downhill, and at high and low speeds.

Why should you get your UTV dyno-tuned?

The main reason to get your UTV’s engine dyno-tuned is to improve its overall performance. Another reason to go for dyno tuning is if you have made significant modifications to your UTV. With such changes, the corresponding requirements of the fuel, exhaust, carburetors, and EFI may require adjusting too to keep up with the engine. Testing the modified engine with a dynamometer can help you to find out what their settings should be. You can then tune everything accordingly.

How long does a dyno tuning take?

It depends on your UTV and the shop undertaking the tuning work. If your UTV has any mechanical problems, the tuning can last from 15 minutes to eight hours. If an experienced tuner is handling the work, they might be able to shorten the duration significantly.

How will the dyno tuning improve the UTV performance?

Your UTV engine can gain anywhere from 10 horsepower to 50 horsepower or more with dyno tuning. There can also be improvements in variables like fuel pressure, fuel injection, throttle body, exhaust, emissions, and valve timing. That can improve UTV performance.

Will the dyno tuning process have any adverse effect on the UTV tires?

When the UTV is on the chassis of the dynamometer, there is some chance that the procedure will cause a small amount of wear on the UTV tires. However, it will not be comparable to the wearing when you drive on or off the road. Most advanced dynamometers have a knurled roller surface and a traction control system that ensure a good grip and reduced tire wear.

Is it expensive to get your UTV dyno-tuned?

Dyno tuning your UTV can be expensive, but it can save you on the expenses for major repairs later on. The increase in cost may be because your UTV requires several different diagnostic runs to determine the engine’s baseline and find existing problems. The runs can also show you the vehicle’s status before changes and the improvements after changes.

Can the dyno tuning cost save money on repair expenses?

By dyno tuning the UTV engine, you can ensure it remains in top condition. You can find any wear and tear issues before they escalate and repair or replace parts as needed. That can prevent the requirement for more expensive repairs further down the road. You will also be saving in terms of vehicle performance and efficiency.

Riding your UTV in races, cross-country, through forest trails, along beaches, or other remote and wild locations can be tremendous fun, and the last thing you need on your adventurous excursions is a breakdown, flat tire, or getting stuck. It can happen, though and, when it does, you must be ready to deal with all eventualities. Fortunately, UTVs have sufficient storage space and can carry a well-equipped tool kit. You just need to make sure that it is on the vehicle at all times.

Five Essential Items for a UTV Tool Kit

Every UTV enthusiast must have at least these five essential items in their tool kit:

1. Wrenches and Screwdrivers

These are the essential items that should be part of every UTV toolkit. Wrenches and screwdrivers are necessary for many maintenance jobs, from changing tires to fixing spark plugs. You can get an assorted range of flathead and Phillips screwdrivers, adjustable wrenches, T-handle wrenches, and ratcheting wrenches. It is not necessary to buy entire sets of these tools, but you should have at hand the ones that you are likely to need the most for your UTV model. That way, you can always find the right wrench or screwdriver when you want to fix something.

2. Tow Strap

When you are driving out in the wilderness, your UTV could experience engine troubles and break down. You could also get stuck in a ditch, in mud, or in the snow. In such moments, you will realize the importance of having a heavy-duty, superior strength tow strap in your UTV tool kit. You can use it to get yourself and your UTV out of many difficult situations. The two straps are usually of water and UV-resistant polyester.

3. Spare Belts

Hopefully, you are in the habit of inspecting the condition of your UTV’s transmission belt before setting out on your drives. Such regular inspection can shed light on clear signs of wear and tear, and you can change the belt before it is in any danger of wearing out entirely. However, during long or rough drives, even the best-maintained transmission belt may come under pressure from the heat buildup and could break or burn. To counter such a possibility, you need to have a few spare belts in your tool kit. Then you can quickly replace the damaged belt and continue with your ride.

4. Duct Tape

It may surprise you how versatile duct tape can be for temporary repairs in emergencies. You can use it to hold broken parts together, plug broken hoses, or fix other minor issues. You can even use it for non-mechanical purposes, such as taping a splint for a broken bone.

5. Tire Pressure Gauge

It is common to encounter tire-related issues on trail rides. You could drive over a sharp rock or branch and get a puncture. And that is why you need to include a tire pressure gauge in your UTV tool kit. It can help you to assess the correct pressure when you fix a flat tire.

To ensure your UTV tires last a long time, you have to be careful about not over-inflating or under-inflating them. If you pump in too much air and over-inflate the tires, they might wear out more quickly. On the other hand, under-inflated tires can make it difficult for you to drive the UTV and could even cause accidents.

Other Essential Items

In addition to these five items in your UTV tool kit, you need to equip yourself with safety gear when you go out driving. The safety gear can include a first aid kit, a fire extinguisher, a flashlight, helmets, goggles, boots, gloves, warm clothes, and rain gear. It is advisable to carry replacements for various parts, such as fuses, spark plugs, front and rear axles, ball joints, and tie rods. You should also keep recovery gear like winches, snatch blocks, shovels, pickaxes, and hi-lift jacks.

It will help if you carry sufficient water, food, extra fuel, matches, and lighters with you. You will also benefit from taking along a GPS, a cellphone, and a two-way radio. Furthermore, it is a good idea to inform family members or friends about your whereabouts if you are heading out on a solo trip.

Factory-assembled Jeep Wrangler stereo systems come with eight standard speakers or nine brand speakers. You can get an immersive sound experience with the Alpine Premium Audio System with nine speakers, an overhead soundbar, subwoofer, and amplifier. It should be sufficient for the task if you only want something to listen to while driving.

However, if you are an audiophile and very particular about sound quality, you might find that the factory-fitted audio system is more on the average side. Fortunately, there are many aftermarket options available and, with some research, you should be able to find the one that meets your listening requirements and budget.

What is stereo sound?

Stereo or stereophonic sound is a sound system that uses two speakers or two channels for sound production. These two speakers are generally on the left and right sides of any electronic sound-producing system that uses stereo sound. That includes the Jeep Wrangler stereo systems. There may be a subwoofer for bass sounds.

Most music recording takes place with stereo sound. Audio devices such as headphones, earphones, boomboxes, CD and DVD players, and laptop speakers also use stereo systems. So, if listening to music is your only goal, the standard or branded Jeep Wrangler stereo systems can serve the purpose.

What is surround sound?

Surround sound or multi-channel sound is a sound system that uses multiple speakers or channels (at least five) for sound production. In the five-channel setup, there is a center speaker, a left speaker, a right speaker, a rear or surround left speaker, and a rear or surround right speaker. There is also a subwoofer. With a seven-channel surround sound system, in addition to the five speakers and subwoofer, there is a mid-left speaker and a mid-right speaker.

The multiple speakers of the surround sound system create an all-encompassing sound field and enable listeners to have an immersive experience. The volume and intensity of sound give a perception of depth. It is common in big-screen movies and video games.

Stereo sound vs. surround sound

Jeep Wrangler stereo systems and surround sound systems differ in the following ways:

• Stereo sound systems have two speakers and output sound through two channels. Surround sound systems have at least five speakers and more.

• Stereo sound systems may or may not have a subwoofer. Surround sound systems always have subwoofers.

• Stereo sound systems generally have a left speaker, right speaker, and subwoofer configuration known as 2.1 stereos. If there is no subwoofer, it is 2.0 stereo. Surround sound systems can have five speakers and subwoofer configuration, seven speakers and subwoofer configuration, and even nine speakers and subwoofer configuration.

• Stereo sound systems may have an integrated amplifier or may use a small, two-channel amplifier. Surround sound systems require a dedicated amplifier or an AV receiver.

• Stereo sound systems require minimum cable management. Surround sound systems have to manage more cables.

• Stereo sound systems may be easier to install than surround sound systems.

• Stereo sound is generally for music and television shows. Surround sound is more common for movies and video games.

• Stereo sound is suitable for small to medium spaces. Surround sound is more suited to large areas.

• Stereo sound systems may be less expensive and have lower power requirements than surround sound systems.

Which one should you get?

Jeep Wrangler stereo systems are probably the best choice if listening to music or other audio entertainment is important to you on your drives. If the standard setup or the upgrade option does not satisfy you, there are many excellent aftermarket stereo systems that you can choose. Of course, you can also install a surround sound system in your vehicle, but it may need a separate amplifier to convert the two-channel stereo sounds into multi-channel sounds.

The surround sound system can give you the immersive listening experience you desire, but it can also increase your speaker and installation costs, and you must take care that the sound does not get too overwhelming. Remember that surround sound systems are primarily for large spaces, and the interior of your Jeep Wrangler, however spacious it is, cannot be called a large space. Aside from the over-loud sound, there could placement concerns regarding the multiple speakers, amplifier, and subwoofer.

The clutch is a crucial part of the vehicle that links the engine and the transmission. It transmits the power generated by the engine to the gearbox and can affect the transmission when you select a gear to move the car from the stationary position or change gears while driving.

Without a properly functioning clutch, your car would not move ahead. If you are a good driver and maintain your vehicle well, the clutch should last you for at least 60,000 kilometers. However, aggressive driving or frequent downshifting when driving through heavy, slow-moving traffic can take its toll on the clutch and cause it to wear down sooner.

You will notice the clutch has worn out and needs replacement when the clutch slips, the clutch plates do not get enough traction, and the car fails to gain speed even with increased engine RPM. Other signs of clutch problems are a shuddering vehicle, grinding noises, and hard gear shifts. You can replace or adjust the clutch using clutch adjustment tools. These tools generally come with a clutch kit, but you can also buy them separately.

What is a clutch adjustment tool?

A clutch adjustment tool is useful for manually installing a new clutch or adjusting an existing one. It can be a difficult task since it involves working on the transmission under the car. If you fail to align the clutch disc properly, you may have to spend more time making adjustments beneath the car. With the proper clutch adjustment tools, you can save a lot of time and effort.

How to use a clutch adjustment tool?

Clutch adjustment tools are simple tools, generally made of precision molded nylon, plastic, or steel. Before using them, you need to make sure you have the right ones. The splines of the clutch adjustment tools should match the splines on the input shaft. If they do not line up, the tool cannot fully engage and fit the pilot bearing/bushing, and the clutch adjustment will not work. You should also read the manufacturer’s manual and follow their instructions.

To begin with, it may help to understand the basics of the clutch. In a manual transmission, the input shaft connects the clutch disc to the engine’s rotating assembly. The clutch disc has two sides, and one side is marked to fit facing the flywheel. It is a metal disc that looks like a gear and lies between the clutch and the transmission. You will need to bolt the flywheel to the crank at the engine’s back. There is a recess inside the crank for the bearing, and the clutch adjustment tool’s tip will lock into this to keep the clutch in place.

You can use the clutch adjustment tool in the following ways:

• First, make sure the clutch disc is facing the right direction. That is, the side with the flywheel markings should face the flywheel.

• Next, insert the clutch adjustment tool into it through the disc splines.

• Place the clutch on the flywheel and insert the tip of the clutch adjustment tool into the bearing in the crankshaft’s center.

• Push the clutch to fit firmly against the flywheel.

• Move about the clutch adjustment tool to make sure it is well in place in the bearing.

• Place the pressure plate over the flywheel and bolt it into place.

• Tighten each bolt in a crisscross pattern. First by hand, then by half torque, and lastly by full torque.

• After tightening the bolts in these three steps, you can close the gap between the flywheel and the pressure plate.

• Let the clutch adjustment tool remain in the clutch until it is time to install the transmission.

• Then you can slide out the clutch adjustment tool and fix the transmission.

As you see, using clutch adjustment tools is not difficult. However, as already mentioned, you need to use the right tools. Many of these tools come with markings on the top to let you know which spline clutches they can fit. If you are still unsure about using a clutch adjustment tool or are doubtful of adjusting the clutch on your own, it is advisable to get professional assistance.
