AUTOOL CT400 GDI/EFI/FSI 6-Cylinder Fuel Injector Cleaning Machine & Tester

CT400 combines wide injector compatibility, three voltage modes, 6-cylinder testing, 3 cleaning and 9 testing functions, ultrasonic cleaning, digital control, fluid recovery, and accessory storage. Use CT400 to clean and test standard and GDI-family injectors by selecting the correct adapter, fluid, voltage, pressure, and function for the injector type. Compare standard, EFI, FSI, and GDI injectors only after the correct adapter, drive voltage, test pressure, fluid, pulse, time, and test mode have been selected. Work through the table in order so each observed result leads to a defined adjustment, retest, cleaning, diagnosis, or replacement action. Use the correct test fluid, cleaning fluid, injector voltage, and adapter for CT400. Keep cleaning solution out of the test circuit. Use the manual to verify GDI drive voltage and the required plugs for single-injector testing. Compare CT400 with CT150, CT160, CT200, CT450, CT500, FN606, and FN608 before choosing the right cylinder capacity, injector compatibility, heating function, voltage range, pump configuration, and test functions. Key features • Standard and GDI Injector Coverage: Clean and test compatible standard, GDI, EFI, and long-body FSI gasoline injectors on one six-position bench. • Match the Injector Drive: Select 12 V, 70 V, or 120 V to support different standard and direct-injection injector requirements. • Compare Six Injectors at Once: View leakage, spray pattern, and relative delivery side by side to identify imbalance before replacement or reinstallation. • Complete Clean-and-Retest Workflow: Combine ultrasonic cleaning, operating-condition tests, reverse flushing, and matched retesting to verify whether service changed the result. • Core capacity and control: Slide / drag 1 / 1 • Injector coverage and settings: Slide / drag 1 / 1
