GReddy e-Manage Blue

GSC-50000 and later use e-Manage software; GSC-49999 and earlier use Support Tool. The two connection setups differ, so check the serial number before choosing a tuning cable.

Expanded injector and ignition functions depend on the optional harnesses and setup. Confirm these accessories explicitly rather than assuming them from the controller name.

Blue corrects airflow or pressure signals at five RPM points. PC tables, fuel and ignition expansion require matching software, interface and optional harnesses.

Yes, with the matching optional equipment, up to two additional injectors. The required injector harness and setup are additional to the base unit.

Legacy software supports Windows 2000 / XP / 7, excluding 64-bit systems. Newer systems require software, driver and interface communication checks.

The dials provide basic correction at five operating points. Matching PC software adds more detailed speed/throttle mapping, live tracing and data logging. The physical dials and the full software functions are different levels of adjustment.

Blue’s optional injector function adds fuel; Ultimate supports increases and decreases. Their fuel correction methods and wiring differ.

No. The base unit changes a signal seen by the factory ECU, which still calculates its own response. Direct injector and ignition functions require the specified expansion wiring and configuration.

VTEC / NVCS switching-point adjustment needs matching vehicle signals and optional harnesses. Switching-point control is not full continuously variable cam control.

Select e-Manage for GSC-50000 and later, or Support Tool for GSC-49999 and earlier. Verify communication, then read and back up the existing calibration.
