PARAMS

Enable Closed Loop

ENABLE NARROW BAND CLOSED LOOP

Closed Loop Enable Parameters
These parameters define the operating conditions where closed loop is enable.

FUEL TRIMS
These parameters define the minimum and maximum allowed closed loop O2 Trim.

STEADY THROTTLE
These parameters are used to determine when the throttle is steady. Closed loop is disabled if the throttle is opening or closing greater than these rates.

FUEL CUT TRANSITION
These parameters determine when O2CL fuel cut transition is active for the purpose of disabling closed loop during the transition. Whenever fuel cut is set, O2CL fuel cut transition is active, however these parameters provide an additonal set of criteria to disable closed loop when the throttle closes and after fuel cut is cleared. When the throttle is open, O2CL fuel cut transition is inactive.
When the throttle closes, if the vehicle speed is at least MIN SPEED, and ECT is at least MIN ECT, and rpm is at least MIN RPM, O2CL fuel cut transition is actived and closed loop is disabled.
While the throttle is closed, fuel cut is active, O2CL fuel cut transition is active.
When fuel cut clears and the throttle is still closed, if the ECT is below MIN ECT, or the vehicle speed is below 5mph (8kph), or the rpm is below MAX RPM, O2CL fuel cut transition is deactived and closed loop resumes.


[-] WIDEBAND
TARGET AFR

Target AFR Table
This table sets the WBO2 target AFR based on RPM and engine load. If WBO2 closed loop is enabled, O2 Trim is adjusted to control the AFR to the target value from this table. Both load and RPM scales can be edited.


PID GAIN

PID Contol Parameters
These parameters set the Proportion/Integral/Derivative (PID) WBO2 closed loop contol parameters.


TIMERS

Wideband Closed Loop Timers
These timers control the delay before closed loop is re-enabled.


ERROR

WBO2 Closed Loop Error Parameters
