Link G4 Plus Software Tutorial: Axis Setup
Axis Setup
02.02
00:00 | - Let's start by pressing the F key to show the fuel map. |
00:03 | We can see that we have a fuel table with RPM on the X axis and load on the Y axis. |
00:09 | We're going to make a few changes to this table so you can see how easy it is to manipulate. |
00:15 | First of all we're going to run this engine all the way to 8500 RPM so we're going to need to add some extra RPM cells. |
00:22 | We can get to the axes set up menu by either pressing the X key or by right clicking on the table and selecting axis setup. |
00:29 | This will bring up the axis setup box. |
00:32 | Adding RPM cells can be done by clicking on the add button and simply typing in the required RPM cell. |
00:39 | Alternatively we can scroll through the current cells and double click on any empty cell to make a change. |
00:47 | Likewise, we can change an existing cell by double clicking on it and altering its value or we can delete a cell all together by pressing the delete button here. |
00:56 | We can make similar changes to the load axis but first let's look at changing the load input. |
01:02 | By default the load input is MGP or manifold gauge pressure. |
01:06 | This is similar to manifold pressure but accounts for the measured difference between manifold pressure and barometric air pressure. |
01:14 | This adds compensation for barometric pressure changes, providing a more stable air/fuel ratio. |
01:18 | On a multi throttle body engine, or one that produces very low vacuum, we may want to use throttle position instead of MGP. |
01:28 | This can be done by clicking on this arrow to access the drop down menu. |
01:31 | We can then select TPS main as the load input. |
01:35 | If you're changing the input on the axis, you can quickly select the default axis scaling by clicking initialise axis. |
01:43 | Once you've made changes to the axis, we need to click apply. |
01:47 | This will open a box asking if you would like to interpolate the table values. |
01:51 | This feature interpolates any new cells to retain the shape of the original map. |
