Interpolate

| 00:00 | Another option we have to help speed up our tuning is to use the interpolate function. |
| 00:06 | This function is particularly useful to help follow a trend or shape in a table without you needing to fill in every cell. |
| 00:14 | The interpolate function simply lets the ECU average the values between a starting cell and a finishing cell to provide a smooth, linear change. |
| 00:24 | There are a few different ways we can use the interpolate function and we will look at these now. |
| 00:30 | The first and simplest is to perform a linear interpolation across a horizontal or vertical row in a particular map. |
| 00:39 | We can start by highlighting the range of cells we want to interpolate by holding the shift key and moving around the map using the arrow keys. |
| 00:48 | Pressing the ‘I’ key on the keyboard will perform a linear interpolation across the selected range. |
| 00:55 | When you do this the values in the first and last cells won’t be effected. |
| 01:01 | We also have the option to perform an interpolation across a block of cells and there are a few more options available here. |
| 01:10 | First up, lets go ahead and select a block of cells using the shift and arrow keys. |
| 01:16 | In this case I’m going to select a block of cells three wide and five high. |
| 01:22 | there are a few ways we can interpolate this selection and what the ECU does when we press the ‘I’ key is determined by this setting here on the drop down menu under the interpolate icon. |
| 01:34 | You can select a vertical interpolation, horizontal interpolation or we can interpolate the entire block between the values in the corner cells. |
| 01:44 | The interpolation will be performed when we press the ‘I’ key or when we select the desired setting from the drop down menu. |
| 01:54 | While it gives a slightly different result, the smooth function has some similarities to the interpolate function. |
| 02:01 | This can be accessed here via the ‘smooth’ icon and it what it does is to smooth out any peaks or erratic changes in the table shape. |
| 02:11 | Unlike the interpolate function, the smooth function will keep the general shape of the existing table, but each subsequent smooth operation will continue to remove peaks and troughs and refine the shape of the table. |
| 02:26 | The Undo and Redo functions can still be applied to any interpolation if you decide you don’t like the result of a change. |
