yes the 06 si uses the shield for a tsx. it incorperates the water passeges for the manifold

theres several can lines on these cars.

B CAN (body)
F CAN (fuel system or pgmfi)
K CAN (dlc)
and some cars have other CAN lines such as UART or G-NET.

a CAN line is basicaly a communication line between control units or MICU's (multiplexers)

digital signals are transmitted back and forth on ...

i'm not so sure adapting the rsx k-pro will be possible either. or not so simply anyway.

the 06 si also has a new immobi system.

the rsx immobi control unit talks directly to the pcm and the pcm commands the fuel pump.

the new si has whats called imoes and the immobi control unit talks to imoes ...
