Need spark map from a 1985 Monte SS
I'm new to this board & I'm reluctant to bother you with such old crap that's maybe even on the side of this board, but you seem to know this stuff & I know no other way..
I'm looking to adapt & incorporate the spark table from whatever ECM the Monte had, into an '8330 C3 ECM, to have some sensible base for tuning my L69 305HO.
There's no EGR on the engine now. Would the main spark table in the Monte include advancement for this or would that be in a separate table?
If included, in what areas would approx how much spark need to be subtracted?
Any information or pointers will be appreciated..

NOTE: no guarantee that any of this is correct!
1) I downloaded the 88SS_L69 bin found at Criags site, along with the $40 hack
2) I created an XDF with just the spark table entry using TunerPro

Hey, 
!
There are still some kind people left in the world!
I have been to Craigs treasure chest but it's not easy for someone unfamiliar with the details to tell what's what there..
Now I have something to start with, knowing the numbers, the mask, & that the '8079 was used in the '88 Monte. I think they had begun using roller cams by then, but anyway..
Wish I had a complete hack of the '8330, I just know where the main spark table is..
