Subaru si drive system

Recommended Posts

Hello,

just installed a wrx11 plug-in on a 09 hatch sti that comes with the si system.

wondering if anyone have workout a configuration to get this feature to work with link.

i believe the button is connected via can to the oem(not sure).

if it can be made to work then i would setup the throttle target map,boost and possibly ign timing map to be altered with.

Copy and paste from the email:

The SI Drive status is received into the ECU as CAN AN1.  It can have a value of 1, 2 or 3.  You can use this in various ways depending on how complicated you want to make things.  For example the most simple would be to just put CAN AN 1 directly on 1 axis of your boost and throttle tables and a 4D ign table (not really sure why you would need to change ignition unless it was for different fuel, but you can if you want), or have 2 tables for each and use CAN AN1 to blend between them. 
Another option would be to use GP outputs to completely switch between 3 different boost/throttle/Ign tables 
I have attached some pictures to show some examples.

Use SiDrive directly on a table:

Use SiDrive to blend 2 tables:

Use SiDrive to switch between 3 separate tables:
