Dyno and software usage
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 …

Sure!. The general rule for the Low-Pass-Filter (the one that is set in seconds) is that the filter size shouldn’t be bigger than the test duration / 10 (the acceleration part). As a general rule an inertial dynamometer shouldn’t produce acceleration tests of less than 5 seconds (at the suitable gear), then the minimum filter …
Inertial tests: it is common that the longer the test (higher gear) the more power that the engine can develop, this happens for two reasons: Braked tests: Both issues are considerably attenuated when performing braked tests of a same duration. Additionally, In twin roller dynos there is also another source of differences, which is the …
In an inertial dyno RAW power (power observed at rollers) is basically the same as the Wheel power (power that is available at wheels), with the only exception of the power lost at bearings, which can be ignored. But in a braked dyno using air-cooled eddy current brakes, part of the power is used in …

In most cases we need to know an estimation of the Power at Engine, which implies to record the coast down phase: friction losses from tyre losses and air-pump losses from brake mainly. This coast down phase must be recorded with the clutch pressed or the Neutral position selected
CVTs normally consist of a set of two pulleys that can change their width and a belt that can travel from a closer position in the drive pulley (and a more open position in the driven pulley) which works as a first gear, to a wider position in the drive pulley as the drive pulley …
Important: the software only uses the Roller Channel for all calculations related to the engine (Transformation from Roller Engine scale to Torque at Engine, and Calc RPM for Graph’s Engine RPM axis). This is done in this way for two reasons: because some engines cannot always provide Engine RPM readings, for instance diesel engines or …
