CAN Boost Map switching (Subaru SI Drive)

[Jamescd]

I am trying to get my SI Drive working with the Link Thunder, the best way would seem to be directly through the CAN input from the stock system. 

 

The inputs are

ID 0x411 BYTE 7 , bit 3/4 is Map Selected
(BYTE 7 = 0x2C – binary 001 01 100) = SPORTS SHARP “bits 01”
(BYTE 7 = 0x3C – binary 001 11 100) = SPORT “bits 11”
(BYTE 7 = 0x34 – binary 001 10 100)= INTELLIGENT “bits 10”

In theory I can isolate bits 3&4 to receive a sequential binary input.

Is there a way to use these inputs to directly control which boost map is selected? It's entirely possible I'm missing something very obvious, thanks in advance!

You could do it several ways, but below is the closest option to how you propose in a binary sense.  Use 2 virtual auxes - you only need 2 as the 3rd combination would be assumed anytime the other 2 are not true.  

 

The other other would be to receive the data as a two bit value - say use something like CAN AN Volt channel, then the 3 switch positions could be represented as a value 1/2/3.  You could put the CAN AN Volt directly onto the boost table axis.
