3D O2 Correction
If a calibrated wideband O2 sensor input is used with closed loop O2 control it is possible to have the ECU
target different air to fuel ratios based on the engine RPM and Load conditions. The target AFR for each
given load and RPM point is set in the 'target AFR map' found in the maps menu. To use this function the
'enable 3D target AFR map' checkbox must be ticked.
The 3D O2 correction map is not a replacement for correct engine calibration and relies on the base tune
being close to the desired levels of fuel delivery.
