Hi Howard,
The zones are defined by two other tables (one for MAp and one for RPM) that you can modify. In its most simple form, you set up 4 RM points and 5 MAP points that all together define 5 RPM sections and 6 MAP sections. Those sections divide up the virtual VE table into 30 zones: 5x6=30 zones.
I have written up a atutorial on how the Virtual VE tables are used (including the zoning) in the EFILive software. It will be uplaoded to our web server shortly.
Regards
Paul
