Datalog

Datalog

Your Elite Series ECU has the capability to datalog to its internal memory. Datalogging can be enabled conditionally off a channel parameter, a switch, or enabled to log all the time. You can also log via the ESP software to your laptop. Onboard datalogging configuration is found in the Main Setup window under the 'Datalog' icon.




Activation Condition

The Activation Condition to enable the onboard datalog to become active is configured here. You can use a combination of these settings to activate the logging. The ECU treats multiple methods of enabling as OR conditions, meaning that once any one of the conditions becomes true, logging will activate. The activation options are:

Always On

When ticked, the on-board datalog will be actively recording whenever the ECU is powered on. (Default unticked)

Datalog Switch Input

When ticked, the on-board datalog will be actively recording whenever the Datalog Switch Input is true. This input can be configured in the Functions screen.

Enabled

When ticked, the on-board datalog will be actively recording whenever the selected channel matches the conditions specified. This function is configured as follows:

  • Choose a channel to activate the logging by clicking the 'Select' button, then selecting a channel from the list and clicking OK

  • From the drop-down menu, select an operator for your channel. Eg you can choose 'Greater Than' to activate once a channel goes above a value.

  • Enter the value you would like to activate the datalogging into the end field.

Data Channels

Your Elite Series ECU can log up to 40 concurrent channels internally. Each channel can be sampled at a rate you specify.

  • To choose the channels to datalog, click the 'Add/Remove' button.

  • In the Channels window, highlight the channels you wish to log, and click the '>>' button. This moves the selected channels to the right of the window, indicating they are selected. You can select up to 40 channels.

  • Click OK when complete

The sample rate of each channel can be individually configured. The Sample Rate is expressed as a time interval between samples. For example, a channel with a 100ms Sample Rate will log 1 sample every 100 milliseconds. A channel with a 5ms Sample Rate will log 1 sample every 5 milliseconds.
It is recommended you sample slower reacting sensors at a lower sample rate, and fast reacting sensors at a higher sample rate. For example, you may choose to sample your coolant temperature at a 10s (second) Sample Rate, but your RPM at a 5ms (millisecond) Sample Rate. A slower Sample Rate will assist in reducing 'wastage' of the internal logging memory.

  • To change the sample rate of a channel, click the drop-down box in the 'Sample Rate' column and choose the desired rate.

For ease of use, the ESP software calculates the Approximate Logging Time and displays it at the bottom of the Data Channels list. Once the on-board logging memory is full, logging will cease and it will need to be cleared via the Data Manager tab of ESP in order to log further.

Laptop Data-Logging

Alternatively, Datalogs can be taken directly through ESP onto your laptop or computer using the Data Manager Tab located at the bottom of the ESP Homepage. See Welcome to ESP for location. By Clickin on the RECORD Button (red circle), all channels will be logged directly to your laptop or computer, available for playback or to be exported to the Data Log Viewer.

  • To select channels to record, select Options > Setup.

  • To chose user definable channels, select Add/Remove, and any available channel can be added or removed to the list of those being recorded.

  • Once channels are set, and a log recorded, Select Playback to display the logged traces. an example is shown below:

  • To export recorded logs, select Options > Export
