    LT1 Buick roadmaster climate control hacking?

    Curious if anyone has ever reverse engineered one?
    Seems it could be low cost display/tool.

    Had no idea even existed until I researched switching my caprice to use a buick digital controller.

    Are you asking about the old Regal / Toronado in-dash touch screen CRT system? I have two and parts of another which I picked up ages ago in the hopes of using them to read the MEFI datastream in my Chevelle. I have since learned the systems are very integrated and do not like to play well with others. As to specifics? I'd have to look through old emails.

    I'm sure they would require the correct datastream and likely E&C bus data to function, and changing that would require extensive reverse engineering of the software inside the unit. I bet they can only handle 160 baud data as well.

    Shoulda been more specific I guess...I was referring to the LT1 b-bodies like caprice/impala/roadmaster.
