GDI vs EFI Injector Testers: Drives, Adapters and Test Functions
Compare the ATT-GD6E and LD-B600 injector-test configurations by drive requirements, connectors, functions and confirmed injector coverage.
Select an injector tester from the injector requirements
A GDI label and an EFI label are not interchangeable compatibility specifications. Start with the injector part number, required electrical drive, connector, mounting and test procedure. Ask the supplier to confirm that exact injector against the ordered machine and adapters.
Do not choose a tester from the number of measuring tubes alone. Tube count describes simultaneous capacity, while electrical drive, connection and test-fluid requirements determine whether the intended injector can be handled by the selected configuration.
ATT-GD6E: documented 12 V, 70 V and 120 V drives
The supplied ATT-GD6E brochure lists 12 V, 70 V and 120 V injector drives for GDI, EFI, FSI and standard-injector applications, subject to the actual electrical and connector match. Those drive voltages are different from its AC 220 V mains input.
Six illuminated measuring tubes support side-by-side observation. A separate ultrasonic cleaner is listed at 40 kHz and 80 W. Confirm the injector fixture, connector assortment, test settings and standard accessories for the delivered package. The published capability does not establish coverage of every injector called GDI or FSI.
LD-B600: confirm the injector type before extending its scope
The LD-B600 listing describes testing and cleaning for compatible high- and low-resistance injectors. It should not be treated as proof of the same high-voltage injector-drive configuration shown for ATT-GD6E.
Send the actual injector requirements for confirmation rather than transferring an accessory or drive claim from the other product. A normal EFI workload and a workshop taking on additional direct-injection applications may require different machine and adapter selections.
Compare testing and ultrasonic cleaning as separate functions
Ask which test functions, adjustable parameters and acceptance method are documented for the offered machine and injector. Confirm the approved test and cleaning fluids, operating instructions, tube measurement method and waste-fluid handling.
Ultrasonic cleaning capability does not by itself establish electrical-drive compatibility or a successful injector repair. Compare observations and results using the machine and injector procedures; do not promise a universal cleaning outcome or injector lifespan improvement.
Keep injector drives and workshop power in separate quotation fields
Record mains voltage, phase and frequency separately from injector-drive voltage. Then list the connector and mounting package, ultrasonic unit, machine/cabinet arrangement and consumables. This prevents a drive rating from being misread as an electrical connection requirement.
The ATT-GD6E sheet identifies the current configuration without a cabinet. Confirm dimensions, packing basis, gross weight and supplied accessories in the quotation rather than assuming every component in an illustrative image is included.
What to send before ordering
Provide injector part numbers or clear identification photographs, vehicle/engine applications, electrical specifications, connector photographs, anticipated workload, mains supply, quantity and destination. Request a written compatibility response for any injector that is not explicitly documented.
The cover is an AI-assisted illustration based on the ATT-GD6E equipment references. It describes the product arrangement, not a completed test on every injector type. Refer to the linked product records and the delivered manual for the actual configuration.
Frequently asked questions
Does a GDI tester automatically support every EFI injector?
No blanket coverage is assumed. Confirm the required electrical drive, connector, fixture and operating procedure for each intended injector against the exact machine configuration.
Does the 120 V ATT-GD6E figure describe mains power?
No. It is an injector-drive figure. The listing separately specifies AC 220 V mains input.
Can ultrasonic cleaning capability prove injector compatibility?
No. Electrical drive, connector and mounting requirements must also be checked. Cleaning and testing are separate functions.
This guide supports early equipment planning. Final dimensions, specifications, installation instructions, supply scope, and applicable documents must be confirmed for the exact model and site before ordering.
