When you install the Seicane system you lose the cluster info. That is a separate issue that as I understand this thread is resolved by the iBus install.

I am following along but in order to do the iBus thing I will need the instructions in one post. I have an aftermarket amp and subwoofer. It was originally the DSP system and I can still adjust sound using the DSP Settings. What I don't know is since I had the DSP system will my setup still be a DSP setup or is it a straight forward install now that I have the aftermarket amp and subwoofer. My guess is the install, and that is entirely what it is, will be straight forward ignoring the DSP past.
