Modifying Maps

| 00:00 | - While we're made it clear that this course is not intended to specifically show you how to use OLS to tune the vehicle, rather we're of course finding and defining maps, we will still need to understand how to utilise WinOLS to manipulate and change our map values when it does come time to the tuning and this module is going to show you some of the techniques that you an use to do so. |
| 00:23 | Realistically once we've actually defined the maps, using WinOLS is not specifically too different to any commercial tuning software package but of course there is a bit of a learning curve involved with understanding the user interface and the different options available for manipulating the numbers inside of your maps. |
| 00:42 | Let's start by getting WinOLS open and what we're going to do is come down and open an existing project, of course this will be included for you at the bottom of this module, we're going to be working on our MK5 Volkswagen Golf file and specifically here we want to open our tuned variant. |
| 01:00 | Now opening this, we've got all of our folders open so we're going to start by moving across to the right here and we're going to close all folders, this will allow us to work through this a little bit easier and find what we're looking for. |
| 01:14 | The process doesn't really change, irrespective of what map you're going to be working with but for simplicity here we'll come down to our ignition timing maps and we'll choose one of those maps. |
| 01:26 | That map's now opened and we can see at the moment we're looking at it in text view. |
| 01:30 | We can look at it in 2D which is really relatively useless, or 3D view when we open this you can see that it does prompt us to click or to use control B in order to optimise the view so we can do exactly that. |
| 01:44 | Now we've got a more conventional 3D table view. |
| 01:47 | I will note that by default you may not end up with your table nicely coloured like this, this is an option, we've got this little flag icon up here in the toolbar, by clicking on this I can turn it on or off. |
| 02:01 | If you don't have that option, it's simple to enable, press the F12 key, that'll bring up your configuration menu and what we want to do here is be looking at our view and 3D mode. |
| 02:12 | Specifically here, the shade areas little tick box is the one that we want to tick if you want to enable that colour coding that we've just seen. |
| 02:21 | Right let's start by heading back to our text view though and we'll get a bit of an understanding of what this map is and of course it is a conventional ignition timing map. |
| 02:30 | We've got RPM up here on our horizontal axis and we've got our relative cylinder fill in percentage on our Y or vertical axis. |
| 02:39 | The numbers inside this table of course are just ignition timing values. |
| 02:44 | And what we can see at the moment is that our table exceeds the screen limit so we can use our little bar on the bottom to scroll across and we can already see that of course this is comparing to the original file, being that we opened our tuned file so we can see that we've got these red values here showing that the numbers have been increased over and above the original untuned values, remembering we're always comparing to our original file and if we want to get an understanding of the magnitude of those changes, we've got a few ways of doing this. |
| 03:17 | We do have our little icons up here on the toolbar, we can represent those changes as a percentage, we can show the difference, we can also show what those original values were. |
| 03:29 | This particular option here, we'll ignore our scaling values which for our purposes right now, relatively useless. |
| 03:36 | So that's the way we can see the changes that have been applied. |
| 03:40 | We look at this in a 3D term as well, we can actually see the changes over and above our stock values as well and let's just see how we can manipulate the shape of this table so we can get a better sense of the areas we're interested in looking at. |
| 03:56 | So there's a couple of ways we can do this. |
| 03:59 | If we come down into the corner of our table here, we can see the little icon beside the cursor change and if we hold that down, we will be able to manipulate the angle that the table is being displayed on. |
| 04:12 | Personally I prefer to use the shift and control key, so we hold both of those down at the same time and then we can manipulate the table both vertically and horizontally by using our arrow keys. |
| 04:24 | So again not too different to what we'd probably expect from most aftermarket ECUs as well as most reflashing packages. |
| 04:33 | So here we can sort of see the original values underneath our modified values, again just so we can get a sense of the magnitude of the changes that have been made. |
| 04:42 | Let's now pop back to our text view and we'll see how we can actually make changes to our individual values so for a start, we can actually see we've already got a section here that is highlighted in grey. |
| 04:56 | This is important to understand because any changes we make are going to be applied to these areas that are highlighted in grey so before we actually start, I'm going to use the delete key and that will make sure that we've got nothing highlighted. |
| 05:09 | Let's just choose a value here, we can click on that with our left mouse button and we can see we've got a value of 12.75 in there. |
| 05:16 | Now there's a variety of ways we can manipulate this and you're not necessarily going to always remember the keyboard shortcuts until you're a bit more familiar with this. |
| 05:26 | If you ever do forget, we can always come up to the edit menu here and if we click on that and we come down here, we can see we've got the range of options that we can use in order to make changes so let's have a look at these now. |
| 05:43 | So let's again highlight our 12.75, so if we hold down the shift and press the plus key, that's going to add to our value and if we hold down the shift and press the minus key, that's going to reduce our value and as usual if we are increasing our value, we see it goes red, now I've decreased the value so it has been highlighted in blue so again this just gives us that visual indication of the direction of change we've made over our original file. |
| 06:10 | So this is a relatively quick and easy way of making changes. |
| 06:15 | Typically we wouldn't be making changes necessarily to an individual cell though so normally we'd want to highlight a block of values and make changes to those. |
| 06:25 | So we can do that by holding down the shift key and using our arrow keys. |
| 06:29 | Now the way the block is highlighted is also quite unique here as well, so we can see we've gone straight up our 2500 RPM column and we've highlighted a range of values and of course shift and plus will add to, shift and minus will remove from that entire column all at the same time. |
| 06:48 | However if we want to highlight a block out to the right, let's say we want to highlight everything we've got there in the 2500 RPM column but also the 3000 RPM column beside. |
| 06:58 | So typically we'd expect here, if we hold down the shift key and use our right arrow key, that will do what we want but you can see that that's not how this actually works at the moment and this is because of our selection mode. |
| 07:10 | So let's have a look at how that works, what we can do is just right click here and what we want to do is come down to our selection mode. |
| 07:18 | At the moment we are on consecutive so let's have a look at the rectangle option instead, we'll just delete what has been highlighted. |
| 07:27 | Now we can do exactly what we would expect from coming from a conventional aftermarket standalone or reflashing package. |
| 07:34 | So not understanding this selection mode can be pretty frustrating until you find that particular function. |
| 07:41 | Now another element here that you can do when you're making changes to the likes of a timing map or maybe you want to make a change to your lambda target table is you can actually highlight where abouts the engine is accessing through this map so not 100% sure what this would look like here but let's say we're looking at something like that up to about 2000 RPM and at the moment I should mention as well, rather than using the shift and arrow keys I'm just using the mouse here, holding down the left mouse button and dragging and that will do the same thing. |
| 08:13 | So maybe as we get a little bit higher and we get a little bit more boost on, we're going to go through something like this and then as our RPM climbs we may find that we drop down a little bit so we might end up with a bit of a movement through the map that looks something like this if we're doing a ramp run on the dyno. |
| 08:32 | So now that we've got that all highlighted, we can use our shift and plus key or our shift and minus key to make block changes to that entire area that the engine's running through all at the same time. |
| 08:43 | Of course if you make a change that you're not happy with here, control Z will also undo those changes so a lot of flexibility on how you make those changes. |
| 08:52 | Remembering again to unselect the areas that you have got selected at the moment, we can press the delete key. |
| 08:59 | Alright let's have a look at some of the other options we've got to manipulate this data. |
| 09:03 | So again let's choose a cell, we'll come back to our same one here that we've already manipulated, we've got it set to 12° at the moment. |
| 09:10 | Let's say we want to enter a specific value, so we can use the equals key here or alternatively we can come up to our edit menu and we can come down to change absolute, same shortcut key of course. |
| 09:22 | Shows the current value here and let's say we want to change that 12 to a value of 14, we can directly enter that and then press the enter key or OK. |
| 09:31 | Now in an interesting twist here, we can see that it didn't actually quite change to 14 and this is one of the idiosyncracies here with OLS, depending on the scaling and resolution of the particular value that we are trying to change. |
| 09:45 | We got close, 13.5 but it's not exactly what we asked for so that is something that we do need to keep in mind there, this is just a limitation with how those values are actually stored and used inside of the controller. |
| 09:58 | Let's have a look at another option here and that is to make a percentage change. |
| 10:03 | Again we can come up to our edit menu and if we come down to change relative, or of course we can use the percent key to make this change. |
| 10:13 | So now we've got the ability to change selected values, we've got the current data which is what we're going to be changing, we've got the ability to choose the math function we're going to be using, in this case we of course do want to use the percentage function and then we can choose the percentage change to make so let's add 10% to that value, we'll click OK and we can see that the change has taken effect there so quite a few ways that we can actually manipulate our data in order to get the sort of results that we want. |
| 10:43 | Another function that we can use here in order to manipulate our data which allows us to make quite large changes with a reasonable amount of control is let's start by highlighting a block of cells here and what we'll do is come back up to our edit menu and what we'll do is come down to the change by edit function and here what we can do is make an addition change a percentage change or an absolute change depending on which of these radio buttons that we are using. |
| 11:14 | And what we'll be doing here is using this matrix to control the changes that we are making. |
| 11:22 | So at the moment we can see that the top left corner will be changed by adding one, remembering we've got the addition radio button pressed, we could make that a percentage change instead but let's stick with addition. |
| 11:33 | So we're going to make a change of one to the top left, a change of three to the bottom left, a change of two to the top right and a change of six to the bottom right and that's going to essentially smooth out those changes and make those changes that we've just requested, we could also choose to add to all of those values so gives us a lot of control there over how we manipulate those values. |
| 11:55 | Now depending how you prefer to tune, sometimes you might want to make these changes in text view but particularly when we're working on a map like this, often it can be easier to actually make these changes in a 3D table view and this also gives you a really good indication of how smooth or not smooth your table is, allowing you to make specific changes if you wish in order to smooth that so essentially the controls are exactly the same here. |
| 12:23 | If I have this highlighted section, that is still remaining from the last little demo that we did. |
| 12:28 | If we hold down the shift key and the plus key here, that will raise or lower all of those values. |
| 12:34 | We can press the delete key and now we can move around, we can see as I'm moving around here where our cursor is going to so we've got this little peak here, maybe we want to just smooth that out a little bit and make sure that all of our table values are nice and smooth so by working our way around, it's pretty easy here just to get a nice smooth table and manipulate it however we want. |
| 12:59 | Again, we can still see our original values underneath regardless whether we are looking looking at this in a 3D table view like this or whether we are looking at it in our numeric values and again, in our 3D table view we can also turn on our colour coding just to get a sense of the shape and magnitude of those values as well. |
| 13:19 | So the process that we've just looked at, again can be applied to any of the maps regardless whether they're 2D or 3D to manipulate them to suit your specific requirements. |
