1997 SL2 Timing maps?

I'm looking for some way to get the timing maps for a 1997 SL2 automatic I own. I have supercharged it and I have a little detonation problem around 5500 - 6k rpms. In order for me to get this deton problem resolved the "right" way I'd need the timing map.
Is this something that I would have to hook the SL2 up to a computer or are these available somewhere?

Thanks!

sorry paul, but i doubt anyone here has that info, but check in "cars in general" ---> "technical" or "turbo/supercharged" forums
