Time Graph

| 00:00 | One of the big advantages with M1 Tune is the time graph function which brings a fully functioned data logging system into the tuning interface. |
| 00:09 | This means we no longer need to download a log file from the ECU and then analyse this log in a separate log analysis application like we did with MoTeC’s hundred series ECUs. |
| 00:22 | In terms of speeding up the tuning process and improving accuracy, this single feature is invaluable. |
| 00:31 | You will find that each of the tuning worksheets in a package have preconfigured time graphs which are set up to display parameters relevant to that particular worksheet. |
| 00:41 | The operation and functionality of the time graphs is consistent with MoTeC’s i2 Data Analysis software and should be very familiar those who have used it. For those new to MoTeC, I will go over the basics now. |
| 00:57 | The time graph can be used to log live data any time the engine is running and the laptop is connected. |
| 01:04 | This shouldn’t be confused with ECU logging which we discuss later in the course. |
| 01:10 | This is particularly useful for looking back at the data during a dyno run, or even a particular event if you happen to be tuning on the road. |
| 01:20 | While watching the live time graph scrolling is great, to do anything useful with it, we are going to want to pause or freeze it. |
| 01:28 | This can be accomplished by pressing the ‘T’ key. Pressing ‘T’ again will continue the logging. |
| 01:36 | Once we have paused the time graph, we can manipulate the data display in a few ways. |
| 01:42 | Firstly we can zoom in on an area of interest by double clicking at the start of the area and then clicking again at the end. |
| 01:50 | This will fill the current graph view with the data we selected. |
| 01:54 | We can refine this further by using the up and down arrow keys to zoom in or out. |
| 02:01 | When the live data is paused, all the channel values also pause and by clicking on a point in the time graph, all the channels will display the values they were measuring at that particular point in time. |
| 02:15 | The most valuable aspect of this is the ghost cursor that shows where in the Engine Efficiency or Ignition Timing table the ECU was accessing. |
| 02:25 | This is a very fast and accurate way to improve the accuracy of your tune. |
| 02:31 | If you want to view the time graph in a bigger format, you can click on the time graph component and then press ‘F6’ to fullscreen the view. |
| 02:40 | This is particularly useful when you are analysing a lot of channels, although you do lose the ability to view the ghost cursor at the same time. |
| 02:49 | Pressing F6 again will return to the normal screen display. |
| 02:55 | If you want to change the way the data is displayed you can easily drag the windows around to suit. |
| 03:01 | If you are working in a custom worksheet or you have unlocked the current layout, you can also add or subtract channels or groups to display almost any parameters you want to view. |
| 03:13 | Let’s see how we can do this now. |
| 03:16 | Let’s assume we are here on the ‘Fuel’ worksheet and we want to remove the parameter ‘Engine Load’, and instead we want to display ‘Coolant Temperature’ and ‘Inlet Manifold Temperature’. |
| 03:28 | If we select the time graph component, we can either right click and select Properties, or use the ‘Alt’ plus ‘F5’ shortcut to access the time graph properties. |
| 03:39 | First we are going to highlight the unwanted ‘Engine Load’ channel and click remove. |
| 03:45 | Now we can click on ‘Add Channel’ and a complete list of channels will be displayed. |
| 03:51 | If we click on the search box and start typing ‘Coolant’, a list of every channel including coolant will populate. |
| 03:59 | We can now click on our desired ‘Coolant Temperature’ channel. |
| 04:04 | Now if we click ‘Add Channel’ again, we can type ‘inlet’ and again the list populates. |
| 04:10 | We can now select ‘Inlet Manifold Temperature’. |
| 04:14 | Pressing Ok will commit the changes and display our new channels in the time graph. |
| 04:20 | You can use the same process to display any channels you want to examine and generally manipulate the time graph to suit. |
| 04:27 | A point to keep in mind is that the preconfigured time graphs included as part of the package worksheets are generally well designed with the specific channels you need to view to perform that particular tuning job. |
| 04:41 | If you feel the need to make dramatic changes, you may be better to do this in a new worksheet. |
