75. Dash/Logging procedure to record Data Log session
1. Select Dash from the Main Window tool bar.
2. Select Configure Dash from the Dash drop down list.
3. Select Log Window from the Pick Dash drop down selection window.
4. Select the Available Signals that you want to appear in the Log Window dash. The selected
signals will also be logged when Record Log, Record Log Icon or F8 quick key are selected.
Be sure to select Scaled Load & Scaled RPM if you want to use the Trace function to assist
with the calibration of the Base Fuel and Spark Maps.
5. After selecting the Available Signals hit OK.
6. Select Dash again from the Main Window tool bar to save the Log Window dash.
7. Select Save To File from the Dash drop down list.
8. Before saving the Log Window dash, you need to navigate to the
C: Program Files/BigStuff/BigComm directory. Note: Step 8 only occurs the very first time
any Dash file is saved. Subsequent Dash file saves will automatically default to the C: Program
Files/BigStuff/BigComm directory.
9. Once you are in the C: Program Files/BigStuff/BigComm directory, you can save the Log
Window dash. You can assign a unique file name by typing the name in and clicking on Save
or save it as the “Default Dash” by clicking on Save with Default highlighted as the file name.
By selecting Default, the Log Window dash becomes one of the new dash’s in the “Default
Dash” compilation.
10. Next select Logging from the Main Window tool bar to configure the data log parameters.
11. Select Configure Log from the Logging drop down list.
12. Select the TPS Threshold (0 – 100% TPS), Log for (0 – 30 seconds) & Update Data While
Logging (yes or no) settings. Next type in a Log File name and hit OK. Note: Once the initial
Log File name is entered, the BigComm software automatically increments, with number
extensions, and saves the subsequent Log Files, associated with the initial file name. You will
need to create a new Log File name to initiate another log data session that is not related to the
initial file name.
13. After entering a Log File name, a Record Log session can be initiated. Again, there are several
ways to initiate a log session. Below are the different log initiation options.
 Option 1: Hit the F8 key.
 Option 2: Select the Record Log Icon in the Main Window tool bar. When the log
window opens, hit the PC’s space bar to start the logging event.
 Option 3: Select Logging from the Main Window tool bar. Then select Record Log
from the Logging drop down list.
Note: Steps 1 through 13 can be configured off-line or on-line. However, you need to be on-
line to record a data log session.
14. After selecting one of the above Record Log options, the Log Window Dash will be displayed.
Hitting the PC’s Space Bar or exceeding the TPS Threshold setting can initiate the Record Log
session.
15. Once the Record Log session is initiated, the BigComm software will begin to record the Log
Window Dash signals. The logged signals will be displayed in the Dash at the bottom of the
screen as well as on the right hand side of the Log Window Dash screen. The signals will be
recorded for as long as the Record Log Time setting (0 – 30 seconds). Note: After the Record
Log session has timed out, the Log Window Dash signals will continue to be displayed, in real
time, at the bottom of the screen (assuming that the engine is still running). Also, if power is
turned off before the Record Log session has timed out, the Log File data will be lost.
