Receiving a calibration file FROM THE
ECU
“Reading a map and variables”
By receiving the engine calibration file or the
vehicle variables from the ECU, the technical can
determine which specific engine calibration file is in
use by the vehicle and what the vehicle specific
variable are included in the data file: throttle min/
max, Throttle body leakage (also known as offset,
fuel injector flow rate, and injector offset).
N
OTE :
When you “receive” an engine calibration file, a
copy of the file stored in the vehicle ECU is loaded
in the software tool main window. The vehicle
specific variables or “calibration” are also loaded.
No information is removed or deleted from the
vehicle ECU.
You can select to receive all the calibration file
from the vehicle ECU or just the throttle body and
injector variables or “calibrations.”
In case of PC failure, it is a good idea, whenever a
file is received from the vehicle ECU to write down
the throttle body and injector variables or
“calibrations.”
To receive
1. Connect the interface cable to the PC and
vehicle.
2. Open the Cannondale Diagnostic Tool software
on your PC.
3. Power-up the ECU.
4. Click the RECEIVE Calibration File (from ECU)
button.
After you click the button, the data transfer will
start. While the data is copied from the ECU to the
PC the progress indicator in the upper right of the
menu will display and the LED on the interface
cable block may appear to flicker. The time
required for the transfer could vary. It should take
place within 1 minute. When the entire data trans-
fer process is complete, you will see the “Receive
complete” message.
5. Click OK.
The vehicle calibration file has now been
copied to the Cannondale Diagnostic Tool
program. 4-SEND Calibration File (to ECU).
