CHAPTER 11 DATA LOGGING
11.1 The Data log Option
Data logging is simply recording the engine data as it is received by the programming PC so
that operation of the vehicle can be assessed. Data logging is particularly useful for
diagnosing problems. The data log records at a nominal rate of ten times per second while the
ECU is online with the programming PC.
The data-logging submenu is accessed through the menu structure under the options menu.
11.1.1 Creating a Data log
There are two methods of logging the engine data; logging to memory or logging to disk.
When logging to memory the data log is limited to 10 pages, which equates to about three
minutes of logged engine data. Logging to disk is only limited by the available space on the
disk from which the software was started.
To start a data-log Start the software in the online mode. The data-log sub-menu is accessed
in the options menu. Select either “Data-log to memory” or “Data-log to disk”
11.1.2 Viewing the Data log
To view the data log you have just taken, press V from the Data log sub-menu. The Engine
Data information will appear as rows across the screen, with a time index at the end of the
row.
At the bottom of the screen is a list of the command keys. They are described in detail here:
↑↑↑↑
- scroll up data log one line
↓↓↓↓
- scroll down data log one line
PgUp - scroll up data log one page
PgDn - scroll down data log one page
Home - jump to start of data log
End - jump to end of data log
? - jump to page #
S - show statistics (max., min. & avg. of each parameter)
ESC - exit
If the power to the ECU is interrupted while a data log is running, the data log will stop until
the power resumes. This will save memory while ignition is switched off.
