Table Axis Configuration
04.47
| 00:00 | Before we get into the actual tuning, I want to talk a little about how we can manipulate or change any of the tables in the M1. |
| 00:08 | This is something we are going to do frequently when you want to add or change rpm or load zones for example. |
| 00:15 | By this point we have already looked very quickly at how to do this but now I’m going to take the time to explain how it is done. |
| 00:23 | Let’s start by heading to the ‘Fuel’ worksheet and we will look at the ‘Engine Efficiency’ table. |
| 00:29 | If we full screen this element and display just the table, you get a pretty good idea of how the axis is set up. |
| 00:36 | In this case we have manifold pressure on the vertical axis and engine speed on the horizontal axis. |
| 00:43 | If we want to change the zones on the table, we can start by pressing the ‘A’ key to bring up the ‘Axis Setup’ screen. |
| 00:50 | We have quite a lot of control through this screen so let’s see how we can use it. |
| 00:56 | First at the top of the screen we have the available axis. |
| 01:00 | In this case we have Engine Speed, Inlet Manifold Pressure, and Ambient Pressure. |
| 01:06 | You can see that if we click on the ‘Ambient Pressure’ tab, the axis is actually disabled by default. |
| 01:12 | If you want to use ambient pressure to compensate your efficiency table, you can tick the ‘Enable Axis’ box to first turn it on. |
| 01:20 | When we do this you can see we now have a little more information shown. |
| 01:25 | On the left hand side we have a table where we can enter up to six pressure sites, and these will be displayed graphically to the right. |
| 01:33 | We have quite a few options as to how we enter the sites for the axis. |
| 01:38 | We can enter them here in this box and press enter, or alternatively we can click next to the site we want to enter and directly type in the value like this. |
| 01:49 | A handy function MoTeC have included is the ‘Generate’ tab here. |
| 01:54 | Clicking on this will let the M1 automatically generate a table based on a first value, finish value and increment. |
| 02:02 | Let’s create a table with a First value of 50 kPa, a Finish Value of 110 kPa and an increment of 10 kPa. |
| 02:11 | You can see when I do this, the value seven is displayed here at the bottom in red. |
| 02:16 | This means I’m trying to generate a table that needs more sites than this particular table has available - In this case six. |
| 02:24 | If we go back and change the First Value to 60, the required sites now changes to 6 and we can press enter. |
| 02:31 | You can see our table is now displayed graphically. |
| 02:35 | Just a note here, you can see that there is a blue and red arrow displayed to the left of the graph which show the minimum and maximum values allowable for this particular table. |
| 02:45 | If we try to enter a value of 1100 for example, it turns red as it is outside the allowable range. |
| 02:53 | Before we close this screen down, there are a few more tabs here I want to talk about. |
| 02:58 | ‘Remove’ simply clears the contents of the currently highlighted site. |
| 03:03 | ‘Clear Table’ will clear the entire table contents. |
| 03:07 | For tables you want to use regularly, you may also choose to export them which will allow you to easily import them into a fresh calibration in the future. |
| 03:17 | If we close the Axis Setup screen for the moment, we can now see this is displayed as a fourth dimension across the top of the efficiency table. |
| 03:25 | We basically have a separate efficiency table at each of the sites in the ambient pressure axis. |
| 03:31 | As usual, the M1 will interpolate any time the ambient pressure is between two of these sites. |
| 03:38 | Before we move on, I want to just jump back to the Axis Setup menu and see how we can change the way the tables are displayed. |
| 03:47 | Conventionally the M1 displays load on the Y axis and engine speed on the x axis, but if you prefer, we can swap the axis around by clicking on this icon here. |
| 03:58 | Alternatively you can select the axis you want to display on the X and Y axis from the drop down menus. |
| 04:06 | If you decide that you want to swap how the individual axis are displayed, you can also reverse the individual axis so that you can have engine speed incrementing as we move up the table or decrementing. |
| 04:19 | It’s up to you and how you prefer to view the table. |
| 04:23 | One point that may frustrate some users who are coming from MoTeC’s hundred series platform is the apparent lack of flexibility in the axis setup on the M1. |
| 04:33 | For example we can’ alter the parameters that are preconfigured as the axis. |
| 04:38 | If for example you decide that you want to use throttle position for the load input to the Fuel Mixture Aim table, this isn’t possible. |
