Calculate Gear Ratios; Add A New Circuit - I2M Chrome User Manual

Calculate gears ratio
Follow this simple procedure to configure the gears on your Chrome:
-­‐ Check that speed and RPM inputs have been already configured correctly
-­‐ In the "data acquisition" menu, set the following parameters for the acquisition: ACTIVE,
100Hz, autostart channel on "SPD1" and speed equal to 20km/h
-­‐ Turn on your bike, then change gears keeping each one for at least 10s and making sure
that the "rec" text appears below the GPS indicator
-­‐ Turn off your bike, then select the "calculate gears ratio" option from the "analog and digital
inputs" menu
-­‐ Configure again the data acquisition as you like
Chrome calculates gears referring to the sessions of the day. Therefore the procedure can be
performed even simply driving the bike in the street or in the circuit, taking care that all the gears
are engaged and executing all the calculations in the same place and day when data have been
collected (Chrome checks both place and day).

Add a new circuit

If a new circuit shall be added, two different paths can be followed:
1) update the entire library using Danas
2) modify a circuit on the track
Update the library through Danas
To update the library, open Danas, go to the "Online" menu and select "Configure Chrome
circuits". From the left list choose 20 circuits and add them using the "+" button.
Ended the choice, create the file using the enter arrow button.
Move the CircuitiInOut.ccr file to an empty USB key (FAT or FAT32 formatting). Connect the
USB key to Chrome and import circuits using the appropriate command in the import submenu
into the "Chronometer" menu.
WARNING: The selected circuits must be EXACTLY 20.
Edit a circuit on the track
Follow these steps:
-­‐ In the "Chronometer" menu, choose "select circuit" to open the "circuits" menu, then select a
circuit (keeping DN button pressed) that is FREE or a circuit that can be replaced
-­‐ In the "circuit details" menu choose "update name" to set the name of the circuit
-­‐ Change the finish line position by putting it in "absent"
-­‐ To manually choose the finish line position, select "update finish line position" and set
"UPDATE", then press a button in the position corresponding to the desired finish line;
otherwise set "AUTO" to use the automatic configuration
