Best Programmer for 24v Cummins: Our Top Picks

In a hurry? Here’s our top 8:

You might be driving a Dodge truck with a reliable diesel engine, but there’s a simple way to unleash even more power. With the best programmer for 24V Cummins engines, you can get everything out of the motor it was built to provide.

However, it isn’t always easy to find the best 6.7 or 5.9 Cummins tuner. That’s why we’ve put together these 5.9 and 6.7 Cummins programmer reviews, along with a comprehensive buying guide to steer you in the right direction.

What is 24V Cummins?

The 24V Cummins is a diesel-powered motor known for reliability and performance. It is found in a variety of light- and medium-duty models.

While the company has been around for a long time, it phased out the 12-valve 5.9 with the 24-valve replacement. This completely redesigned engine uses an electronically controlled injection system and enhanced efficiency.

How Do Cummins Diesel Tuners Work

When it comes to Cummins diesel tuning, you have several options, from the programmer to the tuner. However, both perform the same basic function; they allow you to make changes to the way the motor works.

While the engine comes with preset configurations, you can alter some specifications to make it run differently. You can choose to alter the efficiency or increase the power on both small and large scales.

Let’s face it; the manufacturer didn’t intend for you to access all of the power that your Ram truck is capable, but it’s there for the taking. With the right configuration, you see what this beast is truly made of.

Benefits of a Cummins Programmer

Why would you buy a 6.7 or 5.9 Cummins programmer? First and foremost, it provides more power to get the job done. However, there are some further benefits. Let’s look at them all.

• Gain more horsepower
• Increase torque
• Create better fuel efficiency
• Affordable option to boost performance
• Design a custom fit for your driving style
• Achieve a cleaner burn

Some of the tuners also allow you to read or delete trouble codes for even more versatility.

How To Choose The Best Diesel Programmer

If you want to find the best programmer for 5.9 Cummins common rail engines, you must follow these guidelines.

Compatibility

If you are looking for a 2001 Cummins programmer, you won’t look for the best tuner for 5.9 Cummins or another year. While they might still work together, it’s important that you find the tuner that’s compatible with your model and year. Not only does Amazon provide the Garage function where you can check compatibility, but the manufacturer of the tuner should tell you what trucks it works with.

Power Options

The best programmer for 5.9 Cummins engines are going to provide quick and preset power options to choose from. You can opt for a setting that alters the fuel economy, horsepower or torque without customizing anything. This is the ideal tuner if you want to make changes on the go and don’t have the time to play around.

It’s also good to look for a tuner that allows you to revert the engine back to stock specifications, just in case you need to take it to the dealer or you are selling it.

Setup & Install Time

The majority of engine programmers are simple to use and don’t require any expertise. However, you want to carefully read the diesel tuners reviews to determine if you will be able to use it.

Look for a tuner that plugs right into the OBDII port of your Ram truck. If you choose the chip format, you will have to install it under your hood, which can be more complicated.

ECM Download Time

After you make adjustments with your 24V Cummins engine tuner, you want to know how long it will be until you see the difference. The best modules give you immediate results that can be easily measured.

Customer reviews will give you a good idea of what to expect, but remember that the first engine configuration change might take longer than subsequent as the system gets set up. For this reason, allow yourself a little extra time with the first adjustment.

Display Size

If you want a cheap programmer for 24V Cummins, you can save by choosing a smaller display. However, these can be very difficult to see and make it much easier to make a mistake while tuning.

If you can spend a little more, we recommend buying a programmer with a larger display. Look for extra features, such as split screen, swipe capability, touch screen or a color display.

Storage Options

After you take all that time making engine adjustments, you don’t want to have to figure it all out again. That’s why it’s important to choose a programmer that allows you to store your custom plan.

It will cost you more to get a tuner with storage spots, but it’s well worth the expense. Look for units that offer five to twenty spots, depending on how many adjustments you want to save.

Added Versatility

You can buy a basic 24V Cummins tuner, but you will lack a lot of the best options that enhance your ownership. Instead, consider adding on some features that will prove useful, such as adjusting fuel efficiency if you are hoping to save money at the pump.

You can also find some models that allow you to read and erase DTCs. If you don’t want to take your Ram to the mechanic every time the Check Engine Light comes on, this option saves you money in the long run.

Appearance

While this can’t be the main factor, you do need to consider the style. After all, who wants a bulky, ugly-looking piece of equipment sitting on the dash of their beastly truck?

It’s best to choose a model with a sleek display that blends into the cabin. You also want a model that isn’t distracting. Browse the available options until you see one that appeals to you.

Price & Warranty

We understand the need to find a low-cost engine tuner for your 24V Cummins, but if you only look at the price, you are going to miss out. Too many unreliable companies are undercutting reputable brands by offering a cheaper tuner, but it is you that loses.

We recommend only shopping from a reputable manufacturer. Otherwise, you might just throw your money away. It’s also good to choose a diesel engine tuner with a warranty, just in case there is a defect.

Our list wouldn’t be complete without one more option from this superior company. This Smarty Jr. Tuner offers three power levels. Choose to add 40, 70 or 100 horsepower. Aside from unbridled horsepower, you can also customize the fuel economy and drivability settings for a better overall ride.

The ECM download time is going to take up to five minutes, so it might be a little longer than you are used to, but well worth the wait. However, you can’t make adjustments on the go because of this delay. Still, there are so many options; it’s hard for other models to compete. Use it to adjust the tire height, optimize torque or recalibrate your speedometer.

You can also revert back to the stock settings if you need to visit the dealership. Additionally, the device reads and clears DTCs, offering even more value for your investment. There are no tools to get it installed, ensuring that even if you are a beginner, you can access more power.

Sadly, there isn’t a very large display. If you want a bright color screen, you might need to choose one of our other options.

Engine Programmer vs. Tuner: What’s the Difference?

When the time comes to upgrade your engine specs, you have several options, even though the names are often used interchangeably.

Diesel Tuners

The tuner is also called a chip. It is installed directly to your Cummins engine PCM/ECM module, although some can be plugged into the OBDII port.

With this direct link, you can make “on-the-fly” adjustments. This term simply means that it is easy to adjust the performance while you are on the road.

However, chips and tuners do not reprogram the control module. Instead, it simply changes some of the parameters in real-time.

Diesel Programmers

Your programmer goes into the OBDII port, allowing the PCM and ECM to receive completely updated programming. When you upload the tuning specs to the control module, you alter the parameters that the engine uses.

You can opt for settings that are best for performance, efficiency and more. The in-cab display also shows you the specifications you want to know, such as the coolant temperature, engine load, fuel pressure, exhaust gas temperature, transmission temperature or boost.

Using a programmer isn’t as instantaneous as the tuner. You will make the changes and upload it with the engine off, meaning you can’t change anything while traveling. Plus, the settings could take several minutes to alter.

Diesel Modules

This is the most complicated way to change the Cummins engine specs. You will install a box or module under the hood of your truck. It intersects with several sensors, such as the manifold pressure and fuel pressure.

The module then tricks the engine into adjusting based on the specified readings. You can use this to create more boost, torque, efficiency and more. For example, you can cause the engine to think it is receiving more airflow than it actually is, thereby adjusting the fuel/air ratio.

Sometimes, people choose to use a module in conjunction with a tuner or programmer, but it’s not necessary.

Installing a 24V Cummins Engine Programmer

Let’s assume that you choose the easier programmer setup that goes directly into your OBDII port. If so, you will follow these instructions for installation.

1. Take the diesel engine tuner out of the box.
2. Inspect all of the components to ensure everything was included.
3. Read through the directions provided by the manufacturer.
4. Plug in the engine tuner to your OBDII port.
5. Follow the on-display prompts to make necessary changes.
6. Take your truck out for a test ride and see how it performs.
7. If it’s a setting you enjoy, be sure to save it in the storage for use later.

FAQ

Are 24V Cummins good?

Bulletproof would be an appropriate word used to describe these engines. Okay, maybe they aren’t completely indestructible, but pretty close. When you do a quick search online, you find these are some of the most reliable diesel engines on the market.

Is 24V better than 12V Cummins?

The 12-valve Cummins uses a mechanical P7100 pump that was slightly more reliable than the 24V. However, you can’t tune the 12V Cummins without using modified injection pump parts. Still, the 24V is still extremely reliable and is simple to tune.

Is a 5.9 or 6.7 Cummins better?

The 5.9-liter common-rail Cummins was in production from 2003 through 2007. It includes a fixed-geometry turbo and is incredibly reliable. In comparison, the 6.7-liter has a different turbocharger design, making it more responsive at lower RPMs. Plus, it utilizes an effective exhaust brake function that might make it better than the 5.9L.

Is it safe to program a 24V Cummins?

The 24V Cummins isn’t an engine that is easily broken. You can trust the pre-programmed settings of a tuner to get the most out of this engine. You can also custom design your own parameters. However, keep in mind that pushing the engine too hard can eventually lead to some side effects. If you plan to push the engine hard, you might consider adding head studs or performing some other upgrades for additional support.

Does tuning a 24V Cummins ruin the engine?

If you are responsible with your engine tuner, you shouldn’t cause any damage. We always recommend following the manufacturer guidelines.

By using a tuner or programmer, you are only unleashing power that the motor was already capable of. Plus, the higher-end models provide a way to track the real-time data and watch for signs of engine failure, so you are further protected.

Conclusion

It’s not difficult to unleash the full potential of your Cummins diesel engine with the right tools at hand. Read through our guide to find the best programmer for 24V Cummins engines and see what your truck is capable of.
