Closed Loop Enable/Disable:

  This menu enables or disables closed loop operation.  There is typically no reason to turn off 

closed loop operation unless you suspect an oxygen sensor problem and want to disable the sensor.  

Note: 

 Self-Tuning requires 

closed loop operation to function. 

 

Closed Loop Limit:

  The maximum percentage the ECU is allowed to deviate (+/-) from the base fuel calibration in order to 

maintain the commanded target air fuel ratio.  This is set to 100% by default and under most circumstances should n ot need to 
be changed.

 

 

Closed Loop Speed:

  

This is the “speed” (gain) at which closed loop operation occurs.  This can be set to five levels, 1, 2, 3, 4, 

or 5.  3 is the base setting and should be good for most applications.  4 or 5 is typically not used as the closed loop speed may 
be too excessive for certain applications.   If the oxygen sensor is installed far back in the exhaust (more than 1 foot back  from 
the collector in long tube headers), a value of 1 or 2 may be needed. 

 

Open Loop Below This:

  This setting is usually zero.  If an extremely large camshaft is used (specs only typically found on race 

camshafts), the overlap sometimes causes a “false lean” reading at low RPM. In these cases, it may be required to put in a value 
of 1500-2000 RPM so the system operates open loop below this RPM setting.

34.3  Advanced Learn 

 
Choosing ADVANCED LEARN will allow you to modify the LEARN COMPENSATION LIMITS.  This value is set to 100% by default, and 
should remain there until ample driving time and tuning has occurred.  The LEARN COMPENSATION LIMIT is a parameter that ECU is 
allowed to work within when making changes to the fuel map based upon CLOSED LOOP operation.  Unlike the CLOSED LOOP LIMIT 
which is a set parameter for commanded changes to actual fuel flow based upon the O2 sensor reading, LEARN COMPENSATION 
LIMITS are the percentage of change that is allowed to actually be saved as a modifier to the fuel map.
