Hell, if adding sliders is seen as a no-no (Not that I agree with that assessment, but regardless), why not at least give us the actual information about timing and lift? At the moment, all I know is I have a mystery amount of timing, and then I turn a vaguely named slider to a different number, and have a mystery amount more timing.
This has bugged me about cam and ignition since the beginning in the game. I completely get trying to simplify things for the non-car person, truly I do. But that doesn’t mean you can’t at least provide information to those of us who want it.
