I have just rigged up my LT1 with DFI not too long ago and I wanna get her off in ther ight direction. Since I do not run a knock sensor with the DFI, I would like to figure out a good solid timing map. I have mildly ported heads with stock CR and a 230/236 XE cam. I don't need that specific timing map, but if someone could give me thier timing map for hotcam or some similar grind XE cam I would be VERY appreciative! I would like the spark tables in referance to KPA, those are the ones I need most, below and above 4K. Thanks you VERY much people for your wealth of information.
