That info is all a few years out of date now. After Vishnu made such a big deal about CPS despite the ~15,000 JB3/JB4 cars who have run without it for years BMS decided to just add it for those that want it. So the JB4 G5 has CPS support now, and large turbo customers now use the BMS back end flash which has dramatically revised advance tables.
