The newest generation of Toyota trucks and SUVs represents a huge change from the platforms that came before them.

Turbocharged engines, available hybrid powertrains, and increasingly sophisticated electronics have completely changed what’s possible when it comes to modifying vehicles like the new Tacoma, 4Runner, and Land Cruiser 250.

Now, COBB Tuning is bringing its proven Accessport platform to these next-generation Toyotas.

Whether you’re looking for improved performance from a mostly stock daily driver or want to build on a modified overland setup, COBB offers several tuning options depending on your vehicle and how far you want to take your build.

What Toyota Platforms Does COBB Support?

COBB tuning products are available for several of Toyota’s newest truck and SUV platforms, including:

• 2024+ Toyota Tacoma
• 2024+ Toyota Tacoma i-FORCE MAX Hybrid
• 2025+ Toyota 4Runner i-FORCE
• 2025+ Toyota 4Runner i-FORCE MAX Hybrid
• Toyota Land Cruiser 250 Hybrid

Exact product and calibration availability varies by platform, but there are three main COBB options you’ll find at KRAVE: the Accessport, Stage 1 Power Package, and Stage 1+ Power Package.

So, what’s the difference?

COBB Accessport

The COBB Accessport is at the heart of the entire COBB tuning ecosystem.

This handheld device connects to your Toyota and allows compatible ECU calibrations to be installed directly onto the vehicle.

Toyota’s factory calibration has to account for a huge variety of driving conditions, climates, fuel qualities, and use cases. The Accessport allows compatible vehicles to use COBB-developed calibrations designed to change engine performance and driving characteristics.

The Accessport comes with pre-loaded Off The Shelf (OTS) maps, allowing owners to select compatible calibrations based on their vehicle and modifications.

It can also provide a foundation for custom tuning as a build progresses.

For someone primarily interested in tuning who doesn’t need additional intake components, the standalone Accessport can be the simplest place to start.

Engine AND Transmission Tuning

One of the biggest features of the Toyota Accessport is that tuning isn’t limited to the engine.

Compatible Accessports can also flash the vehicle’s Transmission Control Module (TCM).

COBB offers OTS transmission calibrations that can change characteristics including:

• Shift points
• Shift firmness
• Skip-shift behaviour
• Torque limits

This gives owners the ability to change more than just how much power the engine produces. It can also change how that power is delivered through the transmission.

For modified trucks running larger tires, carrying additional weight, or simply being used differently than a completely stock vehicle, having control over both engine and transmission calibration opens up some interesting possibilities.

COBB Stage 1 Power Package

The COBB Stage 1 Power Package takes the Accessport and pairs it with a COBB High Flow Filter on compatible applications.

It’s a straightforward entry point for someone who wants to begin modifying the performance side of their Toyota without replacing the complete intake system.

The package includes:

COBB Accessport

Provides access to compatible ECU and TCM tuning, COBB OTS maps, vehicle monitoring, and the ability to support additional tuning as the vehicle evolves.

COBB High Flow Filter

Designed to increase airflow while maintaining effective filtration, the High Flow Filter replaces the factory panel filter while retaining the original airbox.

This makes Stage 1 an appealing option for owners who want to keep their engine bay relatively close to stock while gaining access to the COBB tuning ecosystem.

COBB Stage 1+ Power Package

Want to take things a step further?

On compatible applications, the COBB Stage 1+ Power Package pairs the Accessport with COBB’s SF Intake System.

Instead of simply replacing the factory filter, the SF Intake makes more substantial changes to the intake system to help reduce restrictions in the intake path.

Depending on the application, the system incorporates components including a replacement airbox lid, significantly larger high-flow filter, optimized MAF housing, and reinforced silicone connections.

The MAF housing features a smooth-transition velocity stack designed to increase airflow, while integrated air straighteners help maintain consistent readings from the factory MAF sensor.

The result is a more complete intake and tuning package for owners looking to take the next step beyond Stage 1.

The COBB SF Intake System is also designed to be compatible with the factory tune and applicable COBB OTS maps.

Compatibility varies by vehicle and trim. For example, certain Tacoma Stage 1+ applications may not be compatible with Trailhunter or TRD Pro models, so always confirm fitment before ordering.

Accessport vs. Stage 1 vs. Stage 1+: Which One Do You Need?

Choosing between the three options really comes down to what you want from your Toyota.

Accessport

Best for someone who wants to get into engine and transmission tuning while keeping the vehicle’s intake hardware stock.

Stage 1 Power Package

Adds a High Flow Filter to the Accessport, providing a simple supporting airflow upgrade while retaining much of the factory intake system.

Stage 1+ Power Package

Takes things further by combining the Accessport with a more complete COBB SF Intake System on compatible applications.

The best option ultimately depends on your specific Toyota, trim, current modifications, and where you plan to take the build in the future.

What Is the Gateway Bypass Harness?

Modern Toyotas have increasingly sophisticated electronic security systems, which can make accessing certain vehicle modules more complicated.

That’s why compatible Toyota Accessports include a Gateway Bypass Harness.

The harness connects to the vehicle’s OBD-II port, Gateway connector, and Accessport, allowing the Accessport to communicate with the ECU during certain procedures where communication would otherwise be restricted.

This includes situations such as:

• Initial Accessport installation
• Retrieving an unsupported vehicle ROM
• Recovering from an interrupted or failed flash

Once the Accessport has been installed, the Gateway Bypass Harness is not required for normal map changes or uninstalling the Accessport.

How Much Power Can You Gain?

This is probably the question most Toyota owners want answered.

The answer depends on the vehicle, powertrain, fuel, installed components, and calibration being used.

COBB publishes specific Map Notes, Dyno Charts, and Power Gains for its supported Toyota applications. These are important to review because they show not only potential performance gains, but also the fuel and hardware requirements for each available calibration.

Rather than looking at one peak horsepower number, it’s also worth looking at how the tune changes power and torque throughout the RPM range.

For a truck or SUV, improvements in usable torque and power delivery can be just as important as the final peak number.

Why Tuning Is Especially Interesting on the New Toyota Platforms

For years, modifying a Toyota truck usually meant focusing primarily on hardware.

Suspension.

Wheels and tires.

Armour.

Lighting.

Recovery equipment.

Those are still a huge part of building a Tacoma, 4Runner, or Land Cruiser, but the newest generation of Toyota platforms adds another dimension.

Software.

These vehicles rely heavily on electronic engine and transmission management, which means tuning can now become another part of tailoring the vehicle to its owner.

That’s especially interesting in the overland world.

A modified truck on larger tires, loaded with armour, a roof rack, camping equipment, and recovery gear can be very different from the vehicle Toyota originally calibrated at the factory.

COBB gives owners another way to explore how their Toyota performs and drives as the rest of the build evolves.

Explore COBB Tuning products at KRAVE Automotive and find the right setup for your build.

Important: COBB product, map, and trim compatibility varies by vehicle. Always confirm your exact year, model, powertrain, and trim before ordering or installing tuning products. Review the applicable COBB Map Notes for required fuel, supported modifications, and calibration information. Installing an Accessport over anything other than compatible OEM or COBB software may result in ECU/TCU failure.
