Step 6: Write File to ECU
03.33
| 00:00 | In the final step of our six step process, we're going to now write the file into our ECU. |
| 00:05 | The reality of course is that we're going to be iterating between making tuning changes in our last step and then writing to the ECU, which we're covering in this step. |
| 00:15 | So, there will be a bit of back and forth here, as we make calibration changes and flash them into the ECU to assess the effect of those changes. |
| 00:24 | The process begins here with exporting our file from OLS once we've made our changes. |
| 00:29 | So, to do that, what we want to use is our little export icon here, and we'll click on that. |
| 00:36 | And here we can give the file a name and you can provide as much detail here as you see fit. |
| 00:41 | I'm going to keep this very simple and we're just going to call this stage one and we're going to click ok. |
| 00:49 | Now, we need to decide on the file format for the tool that we're going to be flashing with. |
| 00:54 | And in this case, we're going to be exporting this as a binary or dot bin file. |
| 01:00 | You can also see that OLS has made us aware with this little red error bar that the checksum status, checksums haven't been corrected. |
| 01:10 | That's not a problem, we're not using OLS for our checksum correction here. |
| 01:14 | That's going to be done with our AutoTuner tool. |
| 01:17 | So, we don't need to worry about that. |
| 01:19 | We can now click OK and export the file. |
| 01:21 | And we need to of course give this a name. |
| 01:24 | We can see that AutoTuner by default actually produces a name here. |
| 01:29 | We can use this but I'm going to stick to our normal naming strategy, which of course is the vehicle registration, the type of vehicle and then I've simply added here stage one tune. |
| 01:40 | We can click save and that will save that exported file ready to load into our AutoTuner tool. |
| 01:47 | When we open up our AutoTuner software, we can see we've got the option here of going to our ECU operations and selecting the ECU we want to flash. |
| 01:56 | We did this when we were reading from the vehicle and the process is the same. |
| 02:00 | However, once we've actually used the AutoTuner tool, we'll see that the list of latest vehicles that we've worked with is filled out down below. |
| 02:09 | So, we can simply click on our Audi Q7 and we can see that this is going to be an OBD2 write or read or write as well. |
| 02:18 | So, we've got the option here of course of reading and writing via OBD2 or the bench method. |
| 02:25 | Just another reminder here, if you do choose to write using the bench method, just remember that the vehicle does have two ECUs and they both need to be flashed with exactly the same information. |
| 02:35 | By doing this via OBD2, it's going to do the heavy lifting or the hard work for us. |
| 02:41 | Of course, what we're going to do now is come down to write ECU and we'll click on that and we can choose to write a tune file, which is obviously what we want to do or software from the server if we want to revert the vehicle to stock. |
| 02:54 | So, we'll click on tune file and of course we simply want to scroll down and find the file that we have just saved, which is right here. |
| 03:03 | We can click on that and it'll give us one last warning confirming that we do want to write this file to the ECU. |
| 03:09 | Of course, here we'll click yes. |
| 03:11 | This will now take several seconds to actually write that file to the ECU. |
| 03:16 | Once the file is written to the ECU, our job here is done. |
| 03:20 | And this brings us to the end of our worked example. |
| 03:23 | As usual, if you've got further questions on this worked example, please ask those in the forum and I'll be happy to answer them there. |
