| The **Fuel Adjustments Table** allows rpm-based adjustment of the air fuel ratio relative to the ECU's stock operation. Moving a point up (or increasing the adjustment value by typing in the numeric table) makes the mixture richer; lowering it makes the mixture leaner. An adjustment of, say, -5% means multiplying the stock fuel amount by 0.95 (delivering 5% less fuel than stock). Most adjustments will be negative numbers since stock fuel delivery is a rather rich, conservative mixture. Between rpm points, the ECU interpolates between the two adjacent rpm settings. | The **Fuel Adjustments Table** allows rpm-based adjustment of the air fuel ratio relative to the ECU's stock operation.

| - | The adjustment described in the preceeding pargraph is fully applied only when the value for LoadFactor (essentially the same as Airflow/rev, or Boost) is above 1.6 (about 10 psi of boost). Below a LoadFactor of 0.8 (roughly atmospheric pressure) none of the adjustment is applied. Between a LoadFactor of 0.8 and 1.6, the adjustment is applied proportionally. For example, a -5% adjustment value at a LoadFactor of 1.0 results in a -1.25% adjustment actually applied: | + | The adjustment described in the preceeding pargraph is fully applied only when the value for LoadFactor (essentially the same as Airflow/rev [or Boost adjusted by VE]) is above 1.6 (about 10 psi of boost).
