The bench calculator software allows the user to perform in a few steps all torque and engine power measures: the user only needs to enter a few data of the vehicle, proceed to the so-called "RPM calibration" and finally perform a full load acceleration. During the deceleration phase, Warm-Up PRO calculates acceleration, load cell values, torque, wheel power, and power to the crankshaft. All measurements are made according to SAE J1349: a barometric station is connected to the test bench for automatic temperature acquisition and correction according to atmospheric pressure. All results can be stored, compared, printed, and exported to spreadsheet files. The software is also able to calculate an average curve between different measurements.
A unique feature of Warm-Up PRO is the "EOBD telemetry" feature that allows the user to capture the motor data directly from the vehicle's EOBD socket. A wireless interface avoids complicated cable connections to the sensors. All data recording is synchronized with torque and power measurements in order to produce a complete test report of the engine.
The EOBD Wireless ScanTool software function helps the user to read and delete error codes, read PID parameters, and perform a datalogging directly on the roll test bench. The implemented ScanTool EOBD has a large error code database, including specific manufacturers "P1xx". Our communication speed adaptation algorithm with the vehicle control unit allows the user to work at the maximum communication speed possible with the car under test. In addition, a four-channel data log allows you to record the engine's behavior without recording limits.
The "special EOBD wireless features" are a unique tool for evaluating the main parameters of the powertrain section of the vehicle: air mass, lambda, supercharging pressure and rail pressure can be measured and traced in a graph according to the number of revolutions. The user simply has to perform a short full-load acceleration and the software will generate the graph of the selected parameter according to the RPM. A measurement evaluation software algorithm will determine whether the test sensor is working properly or not.
We've developed the "Upgrade Kit", an our own data acquisition and control system: it could be easily fitted also on old chassis dynos and engine dynos. Our solution (consisting of load cells, electrical panel and sensors) is based on a dual-core NI-SBRIO 9637 board: we acquire, using the FPGA on-board, continuosly the two rollers speed, the two load cells, the external lambda inputs and the auxiliary inputs (e.g. the external knock sensors).
On the Real Time board we've instead developed the EOBD-CAN loop: this choice allows the user to establish the communication between the dyno and the car in a very short time and automatically.
All these features are very interesting and even the oldest chassis dynos can be upgraded at the state-of-the-art.
