Next, is a 3D table of O2 closed loop targets versus RPM and MAP.
It has up to 16x16 cells that can be edited through the PC Software.
There is also an option to setup a different O2 target for burnout
mode, 3-step and 2-step. This target is a fixed value, no matter the
RPM or MAP pressure.
The next screen (6/9) is only shown when the idle is TPS based. Set
a target for idle condition (TPS=0%).

O2 closed loop 7/9
O2 closed loop control limits is a 16 points (8 columns and 2 lines)
table, totally editable, by TPS or MAP, which defines the actuation limits
of O2 closed loop, avoiding the control to remove or add too much
fuel in certain situations.
Auxiliary O2 closed loop:
Aux by time (2-step):
This feature allows the creation of a 16 points time based O2 target
table after the 2-step deactivation, which will overwrite the main O2
target table during the time setup on this auxiliary table. To trigger the
2-step, TPS must be above 50% or RPM must hit the 2-step rev limiter.

Aux Pro-Nitrous by RPM:
This feature allows the creation of a 16 points RPM based O2 target
table to each Pro-Nitrous stage, which will overwrite the main O2 target
table while the auxiliary control is on. This feature is only enabled when
all Pro-Nitrous requirements are fulfilled.
