While they don't alter the enrichment tables as above, U01A does also add a unique alteration to Tip-in Enrichment Compensation B/C (ECT) that increases cold and decreases hot enrichment above 50% port injection, which seemed worth noting:
Tip-In Enrichment Compensation B, row 1.0 (100%): 40°C = -20%; 50° = -60; 60°–110° = -70.
Tip-In Enrichment Compensation C, row 1.0 (100%): -40°–0°C = 60%; 10° = 50; 20° = 40; 30-50° = 30.

In what circumstances that tables B and C are referenced?
