00:00 - In this worked example we're going to follow through the reflashing process being applied on this 2008 version 11 Subaru STi.
00:07 And for this example we're going to be using an open source software package called EcuFlash.
00:13 As a reminder, open source software refers to software that's either usually free or relatively cheap to purchase.
00:21 And usually this sort of software is developed by the larger enthusiast market.
00:27 There's upsides and there's downsides with open source software.
00:30 Obviously the cost is attractive but in some instances we can find that the definitions are limited or unreliable and also if you do get stuck or you've got problems or questions, it's a little bit trickier often than if you're dealing with a commercial software package where there's a user manual available or quick and easy tech support.
00:51 Not to worry though, this worked example is going to be perfect for those of you who are new to reflashing on open source software.
00:59 I'll just cover a little bit about the car, it is relatively stock standard.
01:03 This is a Japanese domestic market model which means that it comes with the two litre engine as opposed to the 2.5 which you'll find commonly in US domestic market and Australian domestic market models.
01:15 The two litre engine also runs quad variable cam control and it's fitted in stock form with a split pulse exhaust manifold and turbocharger.
01:24 We've made a few light modifications.
01:26 The stock turbocharger has been replaced with a slightly larger Kinugawa direct fit turbo, we've also got an aftermarket air filter sitting inside the factory air box and it's fitted with a three inch turbo back exhaust system.
01:41 Now while this worked example is obviously going to be focusing on the version Subaru STi, because there are so many similarities across the wider range of Subaru ECUs, this is still going to be very beneficial for those of you reflashing earlier models such as the version 7 onwards Subaru, WRX and STi as well as Legacy.
02:03 It's also worth mentioning that while in this worked example we will be focusing on using EcuFlash for our reading, editing and writing, there are other software packages that are popular.
02:14 In particular, RomRaider, we'll actually be using RomRaider's logger as part of this worked example and there is another relatively low price system called ecuEdit from epifan.
02:26 Now regardless which of those you're personally using, it's important to understand that this worked example is still going to be helpful.
02:32 The reason for this is that the parameters and the tables inside of the ECU are really defined by the ECU itself, not the software we're using.
02:41 So while there are some slight differences on the layout and how you're going to make your modifications depending on which of those three packages you're using, basically everything you're going to learn in this worked example will still be 100% applicable.
