Question

Quizplus · Accepted Answer

Technician A is correct because adaptive trim (A-Trim) is designed to adjust and correct fuel flow to ensure each cylinder receives a balanced amount of fuel over time. Technician B is incorrect because the A-Trim feature does not eliminate the need for initial fuel flow programming (E-Trim/QR-codes/Cal-codes); it complements it by making ongoing adjustments after the initial programming.
