Technician A says that to program EUI fuel flow rates to an ECM, some engines require a new engine file to be downloaded from the OEM data huB. echnician B says that failure to reprogram the calibration code on injector change-out is unlikely to cause any harm providing the engine runs smooth at idle after start-up. Who is correct?
A) Technician A only
B) Technician B only
C) Both A and B
D) Neither A nor B

Question

Quizplus · Accepted Answer

Technician A is correct because programming EUI (Electronic Unit Injector) fuel flow rates often requires downloading a new engine file from the OEM (Original Equipment Manufacturer) data hub to ensure the engine operates efficiently and within emission standards. Technician B is incorrect because failing to reprogram the calibration code after changing an injector can lead to engine performance issues, increased emissions, and potential engine damage, even if the engine appears to run smoothly at idle.
