Fuel Bank Trims

Overview

  • Bank Trims allow fuel mass percentage corrections to be applied independently to each cylinder bank.
  • Each cylinder can be assigned to either Bank 1 or Bank 2, enabling separate fuel control for grouped cylinders.
  • Bank 1 and Bank 2 each include a dedicated 3D correction table, used to apply fuel compensation based on engine operating conditions such as engine speed and load.
  • These trims are typically used to correct for bank-to-bank fuel distribution differences, sensor tolerances, or airflow imbalance between intake paths.
