Default 2008 STi -- General Tuning Questions (Now with Boost Q's)

***See Post 10 for my current quandary.***

Just a little background:

I got into tuning in 2006 with Enginuity (became Romraider) with my 2004 WRX. Tuned it from Stage 1 up to stage 3.

I know and understand the basics, but now have a 2008 STi and the 32 bit ECU and CAN Bus setup are quite a bit different from the 16 bit ECU in the 04.

I bought the car back in June. Has an Opensource "Stage 2" Pro-tune done on a dyno by a local Speed shop to support the Cobb Short Intake and Cobb Catted Exhaust. It produced 332whp and 376 lb/ft.

I have the Openport 2.0 on the way. My "Antique" Tactrix version 1 will now have to be submitted to the Smithsonian.

Anyway, now for the questions:

1) No green connectors and No Flash block connector?

2) The STi has 3 driving modes. [i]Intelligent, Sport and Sport #.
Is there a different map for each driving mode? For example, when I go to
read the ROM and I have the selector in "Sport" and pull that map and
then do the same thing when its in "Sport #" and compare the maps side
by side....will they be different? Sport for me hits 18 psi and Sport # hits
24...what is this wizardry!?!

3) Wideband access. My old WRX had to use a completely separate USB
cable from the Innovate wideband I had. The 2008 STi has an AEM
wideband. Does the Openport 2.0 access the wideband and show up as a
parameter in Romraider?

These are my main questions....If there is any reference material that could point me to a better understanding of the differences between the 2004 and 2008, that would be great. Or if anybody has any first hand experience with the 08 STi, that would be great too.

Thanks in advance!
