 If error correction has been __disabled__,​ then this value is the final value the ECU is going to use and your turbo will build whatever boost it just happens to build for the given wastegate duty cycle. ​ You can use this mode of operation during setup and dialin to find where you setup naturally needs to be to build the boost you're looking for. If error correction has been __disabled__,​ then this value is the final value the ECU is going to use and your turbo will build whatever boost it just happens to build for the given wastegate duty cycle. ​ You can use this mode of operation during setup and dialin to find where you setup naturally needs to be to build the boost you're looking for.
  
-If error correction has been __enabled__,​ then the ECU references the Boost Target table to determine (for the same RPM and gear) what boost it should be trying to achieve at that moment. ​ It then adjusts the base duty cycle according ​(up or down). ​ It tracks this adjustment with a "​trim"​ value, similar to the short term fuel trim.  The final duty cycle used by the ECU is basically:+If error correction has been __enabled__,​ then the ECU references the Boost Target table to determine (for the same RPM and gear) what boost it should be trying to achieve at that moment. ​ It then adjusts the base duty cycle accordingly ​(up or down). ​ It tracks this adjustment with a "​trim"​ value, similar to the short term fuel trim.  The final duty cycle used by the ECU is basically:
