^^^Check out that site (especially the last 2 chapters)

Is there a way get into the Aurora's settings like this and mess around with spark plug timing, idle speed, and all that sort of stuff like in the Cadillac? It would have to be a different way, cuz the DIC is different, but there's gotta be a way. If anybody knows, I'd like to fool around with it a bit.

Please, if you've ever heard of doing this kind stuff to the Aurora DIC, please tell me how, this looks really cool!

Over time on a few forums I have read a few threads ref trying this but none were successful. I think it all changed with the 4.0L engine.
