There are two possible causes: Bad ratio or slip / tyre deformation: Check the actual engine RPM channel or OBDII RPM channel vs Calculated RPM to see if the actual RPM gets far from the calculated RPM graph, specially in the middle section (due to the higher torque) Excessive filtering: Max recommended filter (LPF: Low …

Note that for this verification we are using the default “New Lambda (10-18AFR)” type for AN1 / LAMBDA1 channel Verifying the Heating Up phase The controller will provide 2 different voltages / outputs for the heating-up and steady phases During the first seconds, the controller is in the heating-up phase and will output aprox 2.5V …
In the standard version 1.2, only Left and Right buttons are “software” buttons, Then the program can implement several functions (menus, etc) depending on the context, while up, center and down are “hardware/firmware”: the DAQ will perform a fixed function even if the computer is not runing, but that prevents to add more functions depending …
In most Braked dynamometers, the brake is installed over bearings and only the load cell prevents it to turn. Then the brake torque is converted to a linear force in the load cell as a result of the TQ / Lever (meters) formula. Note that torque can run in both directions, but normally we would …
Road Simulation is an ADVANCED mode, which is more intended for WLTP cycle, than for testing. Indeed Road Simulation is a kind of modified RAMP which uses a mathematical model to simulate what the vehicle should do in the road according to the instant output the vehicle performs Users that want to use Road Simulation …
Windows can eventually detect a high data stream from the DAQ (and previously from the Weather Station) and decide that it is a MOUSE, it will install the Ballpoint Drivers and will block the access from other applications. The cursor in the screen can become crazy as it will interpret the data from the DAQ …
The Capacitive Clamp (Red) (CAP-1) is envisaged to be used mainly on spark cables (High Voltage from coil to the spark). It senses the High Voltage peaks and sends them to the DAQ. In general it is good for single cylinder engines, Drawbacks: it may get random pulses from other cylinders There is also a …

Well. this shouldn’t be our duty as those are 3rd party sensors, but as it is a common request, these are the general rules:
During the installation / setup process it is common that some settings are not correct which can lead to ‘absurd’ readings (very high or very low). It is important to do this check list: After the installation: It may exist differences specially in high power cars and specially on twin roller dynos High Power Cars …
The provided USB-RS232 adapter has a default latency which results too slow for realtime data displaying. It does not affect to the recording but makes the visualization very slow. There are two options: FTDI Port Manually setting the COM Latency to 1 ms (advanced)
