could be a silly question, but doesnt the amount of adjustability in 1224 make 110108 a little redundant? or are the changes a little more sinister and for a reason? As surely you could just set 1224 to limit at 30 degrees by working out the actual total?
Btw the document does confirm some points to how this differs to the old 518.
Aka More timing/boost and a controllable turbo curve
