| 00:00 | - In this worked example, we're going to be tuning a 2015 Subaru WRX using the Cobb Accessport system. |
| 00:07 | Now this particular vehicle has been lightly modified, it's fitted with a number of Cobb's upgrades and as such we're going to be starting using one of their off the shelf maps. |
| 00:17 | In particular it's got a modified intake system, it's got a modified larger freer flowing exhaust system and it's also got a Cobb front mount intercooler system. |
| 00:27 | Now everything we're going to talk about though will cross over to any other WRX that's been modified with non Cobb parts. |
| 00:34 | As such the tuning process is going to be fairly similar and we're going to go through each of the steps that will be required. |
| 00:41 | Now this particular car is also running on the U.S. 98 octane pump gas. |
| 00:47 | Of course we may need to make some tuning changes, particularly to boost or to the ignition timing if you're running on a lower octane fuel. |
| 00:55 | The 2015 WRX is fitted with Subaru's FA20 DIT engine which is a newer iteration of their horizontally opposed boxer four cylinder engine. |
| 01:05 | It runs direct injection only with no port injection and it runs quad variable cam control. |
| 01:12 | As such, despite the differences between the FA20 and the older EJ series engines, there are a lot of changeovers in the way the ECU operates so even if you are tuning an EJ series engine on the Cobb Accessport, a lot of what we are going to discuss during this worked example will still cross over quite nicely to the EJ series. |
| 01:32 | So let's get started with our tuning. |
