How Edge Pulsar Influences Air-Fuel Ratio Performance

The Edge Pulsar V3 is a piggy-back module that improves the performance and mileage of the L5P Duramax diesel engine. The Pulsar V3 adjusts four major components to build power safely: injection pulse width, injection timing, fuel rail pressure, and airflow. It also allows for adjustments to the speedometer, TPMS settings, and speed limiter. While the Pulsar V3 improves performance and mileage, it does not adjust the air-fuel ratio.

The Edge Pulsar corrects axle ratio changes on GM HDs with gas engines, not Duramax

The Edge Pulsar does not correct axle ratio changes on the Duramax platform. This is because, on Duramax vehicles, the transfer case speed sensor routes to the TCM (transmission control module), not directly to the ECM (engine control module). As a result, the Pulsar cannot intercept and correct the transfer case speed sensor signal before it is sent from the TCM to the ECM.

On GM HDs with gas engines, however, the transfer case speed sensor routes directly to a main ECM connector, where the Pulsar can intercept the signals and correct them before they enter the ECM. Therefore, the Edge Pulsar is able to correct axle ratio changes on GM HDs with gas engines.

It is important to note that physically changing ring and pinion gears in late-model GM trucks will disable the factory cruise control. While the Pulsar will allow recalibration of the speedometer for gear changes, it will not reactivate the disabled cruise control system. Reactivating the cruise control would require full ECM tuning.

The Edge Pulsar is a piggy-back module that does not modify the factory ECM. It can be installed and removed easily, which is beneficial when visiting a dealer for warranty issues. The Pulsar provides instant improvements in performance and throttle response, and includes adjustment features for tire and gear changes, diagnostic trouble codes, TPMS settings, and speed limiter.

The V3 Pulsar adjusts injection pulse width, injection timing, fuel rail pressure, and airflow

The V3 Pulsar is an in-line computer that connects directly to a vehicle's PCM to optimise performance gains, throttle response, mileage, tire size, fuelling, high-idle, and more. The V3 Pulsar builds on the already impressive potential of the original Pulsar and features a redesigned performance strategy. It adjusts four major components to build power safely: injection pulse width, injection timing, fuel rail pressure, and airflow.

The V3 Pulsar is all about bringing together powerful tuning, safety features, ease of installation, and direct control over your driving experience. It provides an instant improvement in performance and throttle response. The Pulsar also includes adjustment features that allow you to account for any changes you've made to your truck. For example, you can calibrate your speedometer for tire and gear changes, read and clear diagnostic trouble codes, adjust TPMS settings on new wheel/tire setups, or even adjust your speed limiter.

The V3 Pulsar offers five performance levels that can be switched on-the-fly by using the vehicle cruise control buttons on the steering wheel. The active power level will be displayed using the speedometer gauge. The new V3 performance strategy adds 50% more power compared to the original Pulsar, with gains of up to 136 horsepower.

The V3 Pulsar is the most advanced product in the L5P aftermarket. It completely changes the driving experience to optimise performance and drivability in every setting, whether you're towing or daily driving.

The Pulsar V3 improves fuel economy, power, and torque

The Edge Pulsar V3 is a piggy-back module that improves fuel economy, power, and torque. It does so by adjusting four major components: injection pulse width, injection timing, fuel rail pressure, and airflow. The V3 also includes a revamped shift strategy for improved shifting across the board.

The V3 Pulsar offers five power levels, which can be accessed on-the-fly through the cruise control buttons. Level 1 is the economy tune, which offers the best fuel economy. Level 2 is the "light tow" tune, adding 58 horsepower and 125 lb-ft of torque. Level 3 is for "heavy towing", adding 78 horsepower and 175 lb-ft of torque. Level 4 is the performance tune, adding 103 horsepower and 234 lb-ft of torque. Finally, Level 5 is the "Extreme" tune, adding 132 horsepower and 293 lb-ft of torque.

The Edge Pulsar V3 not only improves fuel economy, power, and torque, but it also gives the driver direct control over their driving experience. The ability to adjust power levels on-the-fly means that drivers can easily adjust for different conditions and terrain. For example, drivers can roll in economy mode and then bump it up to a higher level when more power is needed.

The installation of the V3 is simple, although it is not easy, especially on 2017-2018 trucks. The middle connector on these trucks has almost no extra length, making it difficult to operate. Additionally, the power steering pump reservoir and return line are in the way, leaving very little space to work with. Despite these challenges, the installation can be completed in about 5-10 minutes.

The Edge Pulsar V3 is a great choice for anyone looking to improve the fuel economy, power, and torque of their vehicle. It offers impressive performance gains, improved shifting, and direct control over the driving experience.

The Pulsar V3 allows users to force a regen in either manual or service mode

The Edge Pulsar V3 is a piggy-back ECM module that can be added to a diesel truck to improve its performance and mileage. One of the key features of the Pulsar V3 is its ability to force a regen in either manual or service mode. This is particularly useful for controlling the regen system in diesel trucks, which can be a challenge due to the high underhood temperatures.

In manual mode, the Pulsar V3 allows the user to initiate a regen while driving, which is ideal if you are unable to stop the vehicle. The manual regen process typically takes between 10 and 30 minutes, during which the engine may make a different noise, and you may notice an increase in idle speed and a slight burning smell. It is important to ensure that the exhaust is facing away from people and flammable materials during this process.

Service mode, on the other hand, requires the vehicle to be stopped and parked in a safe place. To perform a service regen, the parking brake must be applied, the vehicle must be put in neutral, and the PTO must be disabled. The engine should also be warmed up to the appropriate temperature before initiating the regen.

The ability to force a regen in either manual or service mode provides users with greater flexibility and control over their diesel truck's regen system, ensuring that the DPR (Diesel Particulate Reduction) filter is properly regenerated and burned off, preventing harmful emissions and black smoke from being released into the air.

The Edge Pulsar V3 not only improves the regen system but also enhances fuel economy and provides better power, torque, and performance. It offers five power levels to choose from, which can be accessed through the cruise control buttons or, if you have the Insight CTS3 display unit, through the display. Level 1 is the economy tune, offering impressive fuel economy gains, while Level 5 is the "Extreme" tune, delivering silly power and impressive performance but at the cost of fuel economy.

The Pulsar V3 improves 0-60 mph response when driving in performance tunes at level 4 or 5

The Edge Pulsar V3 is a piggy-back module that improves the performance and mileage of the L5P Duramax diesel engine. It offers five power levels, which can be accessed through the cruise control buttons. These power levels are shift-on-the-fly tunes, allowing users to adjust the settings while driving.

Level 4 is the performance tune, which adds 103 horsepower and 234 lb-ft of torque. This tune significantly improves the 0-60 mph response, reducing the time by almost a second. In a test conducted by Holley Motor Life, the 0-60 mph time improved from 8.2 seconds in stock form to 7.5 seconds with the Edge Pulsar V3 at level 5.

The Edge Pulsar V3 provides users with direct control over their driving experience and offers impressive performance gains. It is a valuable upgrade for anyone looking to enhance the performance and drivability of their L5P Duramax-powered vehicle.
