Adding Groups and Parameters
04.19
| 00:00 | - Once you've logged some data, you'll want to view the parameters you just logged in a meaningful way. |
| 00:05 | PC Link is very powerful here and allows just the parameters you want to be shown. |
| 00:10 | You can also overlay certain parameters with each other to make it easier to see what is happening. |
| 00:16 | To view the data we start by clicking on the logging tab at the top of our window. |
| 00:20 | This will take us to the data logging page. |
| 00:23 | The data logging page come pre configured with a number of views but as with the tuning page, we can customise the views to suit what we're interested in. |
| 00:32 | The main window of interest is the time plot window which shows our logged data relative to time. |
| 00:38 | Chances are though that we may want to see some specific inputs that aren't shown so we're going to look at how this window is laid out and how we can adjust it. |
| 00:47 | There are two aspects to the time plot window, groups and parameters. |
| 00:52 | The window is separated vertically into groups and each group can be used to display a number of parameters. |
| 00:58 | In this way, we can overlay the values we are interested in and separate out other parameters to be displayed on their own. |
| 01:05 | This is important to make the data easier to view. |
| 01:08 | For example if we overlaid RPM which may span from zero to 8000 RPM with intake air temperature which only varies from 15 to 45°, the scaling would make any variation or movement in the air temperature trace almost impossible to see. |
| 01:24 | Let's adjust the time plot window to show us RPM, manifold pressure, fuel pressure, oil pressure and injector duty cycle. |
| 01:34 | We start by right clicking on the window and choosing properties from the menu. |
| 01:38 | This will open the properties window where we can change what we want to see. |
| 01:44 | We're going to set up four groups, in the first we will display RPM. |
| 01:48 | In the second we will display manifold pressure and fuel pressure as they all usually fluctuate together. |
| 01:55 | The third window will show oil pressure and finally we will have injector duty cycle. |
| 02:01 | Our default logging view only has three groups so we're going to add another by clicking add group. |
| 02:08 | The top group already has RPM displayed so we don't need to change this. |
| 02:13 | The second group has manifold pressure displayed but we need to add fuel pressure. |
| 02:17 | We can do this by clicking on manifold pressure and then pressing the add parameter button. |
| 02:23 | It's easiest to click in the search box at the top of the parameter window and start typing the input you want. |
| 02:30 | If we type fuel, you'll see fuel pressure pops up. |
| 02:34 | Double click on fuel pressure to add the parameter. |
| 02:37 | You can see that it is added into the position where the cursor was. |
| 02:42 | The third groups is displaying throttle position which we don't want. |
| 02:46 | We can remove this by clicking on it and then clicking remove. |
| 02:50 | Now we can click add parameter again and search for oil pressure. |
| 02:55 | Repeating this process for the last group we can select injector duty cycle. |
| 03:00 | If we now press OK, the changes will be made and we can see our desired parameters displayed. |
| 03:07 | If you want to change the colour of a particular parameter or how it is scaled, this can be done by double clicking on the parameter in the properties window. |
| 03:16 | You can also move individual parameters around or entire groups by using the move up and move down buttons. |
| 03:23 | Once you have a log file displayed you can also zoom in and out on areas of interest. |
| 03:29 | You can zoom in by double clicking the left mouse button at the start of the section you want to zoom in on. |
| 03:34 | And then moving the mouse to highlight the area of interest. |
| 03:38 | Left clicking again will zoom in. |
| 03:41 | You can also move around and zoom in by using the arrow keys. |
| 03:46 | Pressing the up arrow will zoom in while the left and right arrow keys will move through the log file. |
| 03:52 | Holding down shift while using the left and right arrow keys will scroll through the log. |
| 03:58 | If you want to see the entire log file again, you can zoom out by pressing the Z key. |
| 04:04 | You can also adjust the size of the individual groups within the time plot window by hovering over the horizontal border and holding down the left mouse button to drag the window up or down. |
