CHAPTER 10 DATALOG
10.1 The Data-log Option
This option records the Engine Data information at a nominal rate of 10 samples per second
while the engine is running. This data-log is useful for tracking the system's behaviour
through changing rpm. It also facilitates trouble-shooting, as all the ECU's working
parameters are recorded faster than they can be read on the Engine Data Page.
The Datalog Menu is accessed through the Options Menu. (Press

10.1.1 Setting Up the Data-log Page
Before beginning a data-log the data page can only display eight parameters which are
selectable through a simple menu. To access the configuration menu press

10.1.2 Creating a Data-log
You can choose to record the datalog either in memory or directly to disk. To record to
memory, press
∆

in the Datalog sub-menu. This will record engine data in a continuous loop,
up to about three minutes ie.. when you stop the datalog, it has a record of the previous three
minutes of engine data.
Alternatively, you can datalog directly to disk by pressing

. The software will ask you to
enter a filename. When recording to disk, you are limited only by the free space left on disk.
The datalog consumes about 11kbytes per minute of running. The disk supplied has over 20
minutes of datalog space. The disadvantage of datalogging in this manner is that there will be
small gaps in the datalog of a few seconds as a block of information is written to disk. If
datalogging to hard disk, these gaps become insignificant.
You should save the Maps being used at the time of the Datalog to disk. It is advised to do
this before the Datalog is taken. Saving the Maps makes sure that all the engine information
(including the Identification and the setups) are saved to disk. If the Datalog is view offline at
a later date, the Maps will need to be loaded so that the programming software knows the
setup of the ECU and can interpret the data properly.
To stop the datalog press . If you are performing a datalog to memory, the screen will
instantly jump back to the Datalog sub-menu. If you have been recording to disk, there will
be a moment's pause as the file is closed.
