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.
16. Once the Record Log session has timed out, you can either view the Logged data file (see
step 17) or initiate another Record Log session by hitting the R key. Once triggered,
hitting the PC’s Space Bar or exceeding the TPS Threshold setting can initiate another
Record Log session.
17. There are a couple of ways to access the Record Log data file. Below are the options.
• Option 1: Select the View Log File Icon from the Main Window tool bar.
• Option 2: Select Logging from the Main Window tool bar. Drag the mouse to
View Log File from the Logging drop down list.
18. After selecting one of the above View Log File options, select the Log File you want to
view and click on Open. Once opened, the Log File data will appear in the Log Window.
Refer to the
Logging section of the BigComm instruction manual to learn how to
navigate the Log Window screen.
19. The Trace function can also be used in the on-line or off-line mode to help calibrate the
Base Fuel and Spark Maps in the “Record Log” files. “Calibrating with the Trace
Function” is outlined in the next chapter of the manual.
