EFI Diagnostic & Servicing
Electronic Fuel Injection cleaning, flow testing, and fuel economy optimization.
Service Overview
Modern electronic fuel injection systems deliver micron-precise atomization calibrated in milliseconds. Over time, heat soaking and fuel contaminants create microscopic varnishes on injector pintles and carbon build-up along intake valves. Our workshops in Pakenham, Clyde North, and Cranbourne West utilize computerized ultrasonic test benches and live ECU sensor logging to restore factory fuel delivery and optimal engine response.
Ultrasonic Injection Restoration Process
Injectors are submerged in high-frequency ultrasonic chemical baths while pulsed electronically to dissolve baked carbon deposits inside the pintle nozzle.
Flow-bench calibration measures delivery volume in cc/min to verify balanced cylinder-to-cylinder fuel delivery across idle, mid-range, and wide-open throttle.
Electronic throttle butterfly cleaning and stepper motor recalibration to eliminate cold-start stalling and unstable idle fluctuations.
Road test verification checking short-term and long-term fuel trim parameters via OBD-II telemetry to ensure 14.7:1 stoichiometric air-fuel combustion.

Frequently Asked Questions
What does EFI servicing do for my engine?
Over time, fuel varnishes and carbon buildup restrict fuel injector nozzles. Our EFI service restores spray atomization so fuel burns completely and cleanly.
