The latter are calculated by using the ratio between "speed 1" (which should be placed on the rear wheel)
and the RPMs. Both inputs must be correctly configured before proceeding with the computation.
The system will calculate the gears with the data that will be acquired during the day on the selected circuit.
ATTENTION: do not change the circuit between the acquisition and the calculation. Therefore, it is
necessary to start the data acquisition and record a session that includes all the gears for at least 10s each
(see the appropriate section). It is possible to check if the chosen settings are correct looking at the “real
time” menu.
Entering the page of the “Real Time” inputs, it is possible to switch to the next page by keeping the DN
button pressed. The second page is only a diagnostic page that allows to see the value of voltage and
temperature before and after elaboration. This page also includes the absolute values of the oil and gasoline
inputs. The latter input can be used to display the variation of the gasoline signal level sensor when the
content in the fuel tank varies.
Configure Inputs Manually
Using this menu it is possible to configure analog and digital inputs. Select "digital input" to scroll through
“RPM”, “SPD1” and “SPD2”. “RPM” needs only the number of pulses. The pulse number represents the
number of signals the sensor receives for each crankshaft revolution. Usually this number is equal to 1 (e.g.
Suzuki) or 2 (e.g Yamaha). For Ducati 1098 or 1198, using the signal from the pick up sensor, this number
should be set to 24.
Also the speed requires the number of pulses. Similarly to RPMs, this number identifies the number of
pulses read by the sensor for each wheel or pinion revolution, according to the position where the sensor
is placed. If the sensor is placed on the wheel, the number of teeth of both crown gear and pinion must be
set to 1. If the sensor is placed on the pinion (or inside the gear) it will be necessary to set the correct
number of teeth of both crown gear and pinion, to obtain the correct speed. For both speeds, the wheel
circumference must be set.
“SPD1” must be coupled with the rear wheel to read the correct gears. Use the option "analog input" to
select one of the 8 inputs. For each input it is possible to choose the name (selecting each character), the
minimum and the maximum value. The minimum value is the one shown on the display when the input is
equal to 0V. The maximum value is the one shown when the input is equal to 5V.
Automatic Configure (Analogs)
Thanks to this menu it is possible to configure all the typical motorcycle sensors, in a very easy way. Use
the first line to select the channel that has to be configured, use the second line to choose the sensor type,
for example a linear potentiometer, a pressure sensor, a Throttle Position Sensor etc.. During the
calibration, the system will explain all the options step by step. As an example, for the TPS calibration, the
system will ask to close the throttle and confirm, than to open it and confirm.
Among the channels that can be configured, there are also those of oil and fuel warning lights. In both
cases, the system prompts to make two measurements, for example, considering the fuel level, in reserve
and full tank. The software will then identify the threshold as the central value between these two values.
In the case of gasoline it is recommended to use as measurements two conditions near to the reserve to
set a precise value. As an example, choose as the first measurement a condition in which a liter of fuel is
still missing until the original warning light switch off. Made this first step, add two liters to make the second
measurement. In this way, the central value will be exactly the correct reserve level. This method is even
more important for bikes which fuel level sensor is not a linear sensor.
Configure Heart Sensor
This menu is for Chrome Bluetooth connection settings. To use Bluetooth connection you need to plug the
antenna, then by the menu you can turn on/off the connection, search for available devices and connect to
the desired one. If you need to connect to a Polar WearLink PWL Heart Rate Monitor leave PIN equal to
0000.The last feature is for choosing if the Chorome has to give up the search if no device is found in 2
minutes.
