e38 spark tuning

[snax]

Im working on a 2010 camaro with a twin turbo kit, I have it all setup to run speed density with the maf disabled. I have a question on the spark tables, B5101 and B5102 are RPM vs grams/cylinder. Is there some other spark table I should be using or how do I make this table work for me?

Thanks

Make sure you 0 out B5112 it adds to the total, you can make the 5101 and 5102 the same start off low timing above .80 air per cylinder at first like 12 degrees and get lower to like 7-9 for safety to be safe till the air fuel is dialed in, that is very conservative
