Just thought i would put in a post that i myself am doing autronic installs and that the shop i am working at tunes and deals in the autronic system.. have installed on subaru wrx (not the sm4 system), Turbo Bmw (SM4 system), currently installing on a jdm gt-four (sm4 system) and after that i have to do one on a fd.

if there is any pointers on the fd's that somebody has noticed or knows would greatly appreciate the input. will try and help from my end on any questions if any about set up etc.

thanks

 

Have you used the multiplexer with the SM4 yet?

 

The only aplication that the mulitplexer would be needed in for the rotary world would be for the 20B.
