New generation of four-wheel-drive (4WD) dynamometers
Traditional non-synchronized dynamometers, and even so-called "electronically synchronized" models, often create uneven torque distribution, forcing the vehicle’s electronic AWD system to compensate, which can lead to irreversible damage over time
These systems may seem advanced, but they rely on the vehicle's electronics to balance the load, not the dynamometer itself
In contrast, our linked synchronized dynamometer physically synchronizes the torque and speed of all four wheels through a driveshaft, eliminating strain on the vehicle's drivetrain
This ensures precise testing without risking damage to the AWD system, offering a much safer and future-proof solution for high-performance vehicles

RPM PICKUP CLAMP
This is a very important additional feature, and the data it provides is often underestimated. This module uses an RPM sensing clamp probe to directly measure engine RPM from the ignition coil wiring
Direct engine RPM measurement ensures greater accuracy in test data. It is especially important when dealing with complex transmission systems, tire slip, or dynamically changing gear ratios. By directly measuring the engine RPM, you get more accurate data to better analyze the vehicle’s actual performance. This is essential for performance tuning and data analysis.
Directly measuring engine RPM is crucial in dynamometer testing, especially for certain types of vehicles and transmission systems, such as CVT (Continuously Variable Transmission) and AT (Automatic Transmission) vehicles. Here are the main reasons why direct engine RPM measurement is necessary:
1. Accurate Power and Torque Measurement
- Engine RPM is a key parameter in calculating power and torque. If the engine RPM is inferred from wheel speed alone, changes in gear ratios within the transmission system may lead to inaccurate measurements. Direct engine RPM reading ensures more precise power and torque data.
2. Handling Complex Transmission Types
- For vehicles with CVT or some modern AT systems, the gear ratio is dynamically variable, which means the ratio between wheel speed and engine RPM is not fixed. In such cases, inferring engine RPM from wheel speed becomes highly inaccurate. Direct engine RPM measurement provides the true RPM value, avoiding measurement errors.
3. Eliminating Slip and Drivetrain Losses
- During dynamometer testing, there may be slight slippage between the tires and the rollers, causing a discrepancy between the wheel speed and actual engine RPM. By directly measuring the engine RPM, you can avoid inaccuracies caused by tire slip and ensure more accurate data.
4. Synchronized Data Analysis
- In some vehicle performance analyses, it’s important to synchronize multiple parameters, including engine RPM, wheel speed, and torque. Having direct access to the true engine RPM allows for more precise calibration and optimization, particularly when using OBD or CANBUS to synchronize data, ensuring the integrity of the data.
5. Tuning and Diagnostics
- For race cars, tuned vehicles, or high-performance cars, engine RPM is a critical tuning parameter. Direct engine RPM measurement helps engineers precisely determine the optimal RPM range during the tuning process, optimizing engine output and enhancing performance.
DYNO TEST MODE
RPM Control Module
The RPM control module allows the dynamometer operator to manually set the desired engine RPM, and the vehicle will maintain the set RPM range regardless of throttle position. This functionality is achieved through our advanced PID control system, enabling the dynamometer to precisely control engine speed. No matter the throttle angle, the vehicle remains at the desired RPM, simplifying the testing process and making aftermarket programmable engine management system (EMS) mapping more efficient.
Key Features
1. Precise RPM Setting
The operator can freely set the target RPM in increments of 50, 100, 150, 200, 250, or 500 RPM, ensuring flexibility and precision in RPM adjustments to accommodate different testing requirements.
2. Custom Control
The operator can easily specify the RPM input source (hardware RPM such as an RPM pickup module, OBD-II, or ECU) and configure the system as needed, supporting both manual and automatic transmission vehicles. The system also supports custom RPM step values and sensitivity adjustments, further enhancing operational flexibility.
3. Easy Mapping
Simply set the desired RPM, and the dynamometer will automatically maintain the vehicle within that RPM range without requiring the operator to constantly adjust the load or road speed. This makes switching between different tuning MAPs much easier, significantly improving tuning efficiency.
Ease of Use
The operator only needs to set the target RPM, and the dynamometer will take care of the rest automatically. This feature greatly enhances testing efficiency, particularly in engine management system tuning, providing the operator with significant convenience and control.
