 When you change the RPM-based fuel sliders, the ECU doesn'​t **always** use the adjustments you entered. ​ RPM-based adjustments are only made during certain modes of open loop operation in the ECU, primarily the WOT open loop mode.  And even at WOT, the full entered value may not always be used.  The RPM-based fuel sliders can be thought of as adjustments to the A/F mixture only when you're running beyond the highest airflow curve in the ECU.  This curve corresponds to roughly 2.1 g/rev (AirflowPerRev) or about 16-17psi. ​ When you're running wide open throttle with less airflow than that, DSMLink will interpolate according to the fuel curves defined from the factory. When you change the RPM-based fuel sliders, the ECU doesn'​t **always** use the adjustments you entered. ​ RPM-based adjustments are only made during certain modes of open loop operation in the ECU, primarily the WOT open loop mode.  And even at WOT, the full entered value may not always be used.  The RPM-based fuel sliders can be thought of as adjustments to the A/F mixture only when you're running beyond the highest airflow curve in the ECU.  This curve corresponds to roughly 2.1 g/rev (AirflowPerRev) or about 16-17psi. ​ When you're running wide open throttle with less airflow than that, DSMLink will interpolate according to the fuel curves defined from the factory.
