whelp looks like its official.

"There is a BETA version of the ROM editor in the pro download area that give access to the tables that we've found so far for VVEL control. One big piece that is still missing is the cam phasing. There are tables there for phasing, but they don't seem to work yet. Be VERY careful not to change the "Valve Clearance Limit" table as this is the table the keeps the pistons from hitting the valves. Here are the notes about what we know so far about these tables (this info can also be found in the text file inside the beta ZIP folder):

So far we know:
Valve clearence limit is the safety table that keeps the ECU from running too much lift and advance at the same time.

* Adjusting this table is DANGERUS. Too much lift and advance at the same time = piston crashing into the valves.

VVEL B seems to have the most effect on idle.

At WOT it seems take the max value from either B or C."
