Hi guys,
Just starting to write a tune for a VZ6.0 that ill be fitting a turbo to this week. Ive upgraded the o/s to 2 bar .Ive found the boost ve table but there doesnt seem to be a boost spark table. The O.S is 2598977. In the earlier o.s the spark lies in the efi live custom cals section but on this one there is no efilive section . Anyone see what im missing?Cheers

Your not missing anything, there isn't one.
the last columb of the spark table will be carreid through into boost.

GM allowed the spark g/cyl to be scaled from the factory, you can change the value {B5115}.

So lets see if ive got this right, in b5112 where i command say 11.0 afr (eq 1.33)i could subtract timing say-14 degrees at x rpm and that value will be subtracted from the final timing in b5101 for that rpm/g/cyl link once it passes 1.36 g/cyl(im assuming it will with boost). The older ls1s with boost timing are soo much easier.Any other surprises lurking in the 02598977 o.s.
when dealling with boost? Cheers Shane:thankyou2:

B5115 in this o.s. is ethanol spark correction dont think that will help.?
