Using the Cross Hairs
01.39
| 00:00 | - When you are making tuning changes to the fuel and ignition maps, it's important to make sure that you're in the centre of a particular cell before making a change. |
| 00:09 | This is because the ECU will constantly interpolate the actual value it is using from the surrounding cells. |
| 00:14 | So if you're not in the middle of a cell, the resulting ignition timing or fuel pulse width can be swayed by the surrounding values. |
| 00:21 | When the engine is running a convenient cross hairs will follow the active cell around the map showing which cell the ECU is accessing at any time. |
| 00:30 | Before making changes, it's important to ensure that the cross hairs are centred on the cell you want to adjust. |
| 00:36 | The cross hairs will show you very accurately if you are centred on the cell or overlapping with an adjacent cell. |
| 00:42 | Use the cross hairs and the dyno to make your tuning more accurate and repeatable. |
| 00:48 | While the cross hairs are great for steady RPM or load tuning, another feature we can take advantage of during a ramp run on the dyno is the snake trail. |
| 00:56 | This is a red snake that follows the cross hairs around the screen. |
| 01:00 | This is a handy way of seeing which cells the ECU moved through as the engine accelerated. |
| 01:06 | We have two options with the snake trail which can be accessed by right clicking on the map and selecting snake trail. |
| 01:12 | You can turn the snake trail on or off by clicking on the snake trail visible or by using the comma hot key. |
| 01:19 | In this mode the snake trail will gradually fade out over a few seconds. |
| 01:24 | If you want the snake trail to remain visible, you can select snake trail paused or use the full stop hot key. |
| 01:32 | Unpausing the snake trail will have it continue to fade gradually. |
