14. Engine log 

The engine log function is used to keep a record of the engine run-time and maximum channel values since 
last reset. It also holds a record of the number of alarm events and the number of times the driver has 
acknowledged an alarm. 

The engine run-time is broken down into four separate timers as follows: 

  Total run-time with RPM greater than zero  

  Run-time above a specified engine speed 

  Run-time above a specified throttle position 

  Run-time above both engine speed AND throttle position 

These 4 run-times are represented by T1 to T4 on the tell-tale page. 

The RPM and TPS thresholds are specified at the top of the Engine Log page, as is the cranking speed 
threshold below which the maximum channel values are not updated. The “Crank Threshold” should be set 
to a value between the cranking speed and idle speed. The reason we have this parameter is to prevent 
spurious sensor readings from overwriting the log during engine starting when the battery voltage may be 
fluctuating. 

Run times and maximum channel values are read from the dash by clicking the “Get Stats & Run Times” 
box at the top of the screen. 

Maximum channel values and engine run times are reset separately by clicking the “Reset Stats” and 
“Reset Run Times” boxes respectively. Maximum channel values may also be reset by the driver by 
entering the tell-tale page and holding the page button for 2 seconds – see page 11.

15. Data logging 

In addition to the engine log and the recording of maximum channel values, the Geartronics G-Dash has 
full on-board data recording capability. Retrieved data is viewed graphically in our own Dashview data 
analysis software. The Dashview software is automatically installed at the same time as the G-Dash 
configuration software. 

15.1 Setting up logging 

To setup logging and to read/delete data logs, click on the 

Data Logging

 tab at the top of the main window. 

Place a tick in the box against each channel that you wish to log. 

 

Logging parameters are described as follows: 

 

Start RPM Threshold

 – Specifies the engine speed above which recording starts 

 

Stop RPM Threshold 

– Specifies the engine speed below which recording stops 

 

Additional Channel Condition

 – Allows data recording to be conditional on the value of another 

channel 

 

Additional Channel

 – Select from a drop-down list the additional channel used to start/stop 

recording 

 

Additional Channel Test

 – Specifies the condition (greater than, less than etc.) before recording is 

started 

 

Additional Threshold

 – Specifies the value of the additional channel before recording is started 

 

Data Log Speed

 – Sets the sample rate for data recording. Note: all selected channels are 

recorded at the same speed. Options are 10, 20 & 50Hz. 

In order to maximise the available logging time, only record at the minimum speed necessary to provide the 
required data resolution. The software has been written to optimise the logging memory by only recording 
channel values when they change. This saves considerable memory space, especially in the case of 
temperature channels which only change relatively slowly.
