Power Enrichment Correction

When the ECU determines that the engine is being operated under moderate to heavy load, it increases injection duration values by up to 20% to 30%. This power enrichment program is based on information received from the air flow meter or manifold pressure sensor, the throttle position sensor and engine rpm.

The correction coefficient graph above shows a standard value of 158'F (70'C).

• At temperatures below 158'F, basic injection calculations are increased.

• At extremely cold temperatures, injection duration can be increased to almost double normal warm engine values.

• As engine load increases, injection duration is increased.

• As engine rpm increases, injection frequency increases at the same rate.
