Drivers often look for ways to make their cars better. Range Technology is known for its performance tuning devices.
We’re going to check if their products really work. We’ll see if they can change how engines work.
We’ll look at what people say and the technical side. For those interested in AFM disablers, this review has useful info on how they perform and their value.
An Overview of Range Technology Tuners
Range Technology’s main products are advanced OBD-II interface devices. They change factory settings to make driving better. These tuners focus on specific engine features, not a full performance boost.
What Range Technology Offers Drivers
Range Technology creates precise electronic devices for vehicle engines. They mainly work on managing cylinder deactivation systems in modern cars.
Their top products act as an AFM disabler. They stop cylinders from shutting down automatically during certain drives. This keeps the engine running smoothly across all cylinders, not just for more power.
Core principles of performance tuning
These devices keep the engine running well by stopping cylinder deactivation. Unlike other tuners, Range Technology units send signals to keep all cylinders active.
Users have seen great results. One happy customer said:
“The unit does exactly what it claims, it prevents the A8’s Active Fuel Management system from kicking in and eliminates the associated engine shudder.”
Newer models now disable Dynamic Fuel Management (DFM) or Skip Fire systems. This covers more modern GM vehicles.
Primary Applications and Vehicle Compatibility
These devices are mainly for cars with cylinder deactivation tech. They help with the shudder or vibration from AFM/DFM systems turning on and off.
They’re best for daily drivers and fleet vehicles. They offer smoother driving and less maintenance worries about AFM system parts.
Supported makes and models
Range Technology mainly works on General Motors cars, focusing on 8-speed automatics (A8). Their vehicle compatibility includes:
- Chevrolet Silverado/Sierra 1500 series (2014-2019)
- GMC Yukon/Chevrolet Tahoe/Suburban (2015-2020)
- Cadillac Escalade (2015-2020)
- Chevrolet Camaro (2016-2019)
- Chevrolet Corvette (2015-2019)
They’re adding support for newer models with DFM tech. Check their website for the latest compatible vehicles before buying.
Does Range Technology Work: Examining the Evidence
To understand if Range tuners work, we need to look at what they promise and what really happens. This section will compare what the makers say with what real-world testing shows.
Manufacturer Claims Versus Real-World Performance
Range Technology says its devices can stop Active Fuel Management (AFM) and Dynamic Fuel Management (DFM) systems. They claim this makes cars run smoother and might help mechanically.
But, we must be careful with claims of better performance. Some people say their cars shift better and run cooler. Yet, these might be because the AFM/DFM is turned off, not because of any real tuning.
Horsepower and Torque Increase Verification
Looking closely, Range devices don’t change engine settings for more horsepower gains. They mainly disable AFM/DFM systems, not tune the car’s performance.
“The Range device won’t change your car’s performance. Some say their A8 shifts better and runs cooler. But, the device can’t do these things…”
This means the device works well at disabling cylinder deactivation systems. But, it can’t increase power or change how the transmission shifts.
Independent Testing Results and User Testimonials
Tests in controlled settings give us the best look at Range Technology’s effects. Many users are happy with the device’s main job: stopping AFM/DFM. They say it makes driving better and worries less about car problems.
Dynamometer Readings and Fuel Economy Analyses
Dyno tests show Range devices don’t add power compared to stock cars. Real-world testing backs this up, showing the device’s main goal is to disable AFM/DFM, not boost performance.
On fuel economy, results depend on how you drive. Some see little change, while others notice a small drop in fuel efficiency. Without AFM/DFM, cars use more fuel, even when they could save it.
Most users agree with what the devices can do. They’re happy with stopping cylinder deactivation, but not with unproven performance boosts.
Performance Impact on Different Engine Types
Engine design is key when it comes to how performance tuners like Range Technology change how a car drives. Forced induction and atmospheric systems react differently to electronic tweaks.
Turbocharged Engine Results
Forced induction systems offer unique tuning opportunities. Turbocharged engines often see bigger gains from electronic tweaks because of their design.
These engines use exhaust gases to power turbines. This forces more air into the combustion chambers. This leads to more fuel being injected and, in turn, more power.
Ford Focus ST and Volkswagen GTI Case Studies
The Ford Focus ST shows clear benefits from tuning. Owners notice better throttle response and more mid-range torque.
Volkswagen’s GTI also benefits from electronic tweaks. The direct injection and turbocharger management see improvements in boost pressure, torque delivery, and fuel mapping.
- Boost pressure consistency
- Torque delivery smoothness
- Fuel mapping precision
Both cars gain from better air-fuel ratios and ignition timing. Modern turbocharged vehicles offer a lot of adjustment options.
Naturally Aspirated Engine Performance
Atmospheric engines don’t use forced induction. Naturally aspirated engines rely on atmospheric pressure for air intake.
This difference means tuning is done differently. Mods focus on improving what’s already there, not creating new performance areas.
BMW 3 Series and Toyota Supra Evaluations
BMW’s inline-six engines are great examples of naturally aspirated power. The 3 Series models see better throttle response, wider power bands, and smoother driving.
- Throttle response sharpness
- Power band widening
- Drivability enhancements
Toyota’s Supra shows how tuning can enhance existing performance. The focus is on better valve timing and intake efficiency, not forced induction.
These cars get better engine management through tuning. The tweaks adjust fuel curves and ignition maps for better efficiency from atmospheric systems.
Both engine types benefit from electronic tuning, but in different ways. Knowing these differences helps set realistic expectations for performance upgrades.
Advantages and Limitations of Range Tuners
Drivers should weigh the good and bad of Range Technology’s performance tuners. Knowing the pros and cons helps them decide if these devices fit their driving needs and future plans.
Benefits Realised by Users
Many drivers say Range tuners make their cars better. The biggest plus is getting rid of the shudder and vibration caused by AFM/DFM in some GM cars.
Power delivery improvements and throttle response
Users often say the throttle feels better and power delivery is smoother. The tuner stops the car from switching off cylinders suddenly. This makes the car accelerate more smoothly and consistently.
Truck and performance car owners love these changes. The car feels more responsive and connected to the driver’s actions than before.
Potential Drawbacks and Considerations
Even with the good points, there are things to think about before getting a Range tuner. These can affect how happy you are with your car in the long run and its value.
Warranty implications and emission compliance issues
The biggest worry for many is about warranty implications. Even if you can take it out, dealers might see it was there before. As one person said:
“Dealer probably won’t check and it shouldn’t affect the warranty, but removing it will stop any talk about it.”
Another thing to think about is how it affects car checks. The tuner stops some scans, so GM can’t check your car as usual. This might make it harder to get warranty claims or check-ups.
Also, there’s the issue of emissions. Range tuners are for off-road use, but some people use them on roads. This could break local emissions laws and cause problems during car checks.
