The GReddy e-manage Ultimate stands out as an advanced yet cost-effective engine management solution, seamlessly combining the advantages of a “piggy-back” system with the autonomy of a stand-alone management system. Priced economically and leveraging existing sensors, this system allows for convenient adjustments to factory settings without the need for a complete overhaul.

In contrast to its predecessor, the e-manage Ultimate boasts enhanced refinement, requiring specific applications for optimal performance. Regularly updated application downloads, available for free on and Tech WebPages, ensure adaptability to evolving needs. The included PC-based USB “Ultimate Support Tool” facilitates precise tuning, offering improved flexibility in fuel and ignition control, as well as impressive data-logging capabilities to streamline the tuning process.

The expanded number of input and output ports, coupled with built-in adapters, introduces new possibilities. Unique to the Ultimate version are features such as direct Map control for fuel and ignition adjustments, the ability to switch between preset tuning Maps (e.g., Street or Race program), and individual cylinder adjustment options. Additional capabilities include the conversion of injection and ignition systems, airflow meter elimination, and self-tuning of Injector base tuning Maps when used with a wideband A/F Meter.

The e-manage Ultimate also incorporates built-in Boost, Rev, and Speed Limiter-Cut features, ensuring smooth operation. Fine-tuning Correction Maps address factors like Throttle Acceleration, Vehicle Speed, Water Temp, Intake Temp, Auto Trans Shift, Anti-Engine Stall, and Idle for optimal performance. The system’s Monitoring, Map Tracing, and Datalogging features surpass those of other piggyback controllers, offering unparalleled support for tuning.

Noteworthy features include improved RPM recognition, Warning Settings, Password Protection for tuning Maps, compatibility with NVCS (Nissan) and VTEC (Honda), O2 Feed-back, Clean Fouled Plugs, and more through future updates. Tailored for enhancing performance products like Exhaust, Air Intake, Intercoolers, Boost Controllers, and Turbochargers, the e-manage Ultimate bridges the gap between conventional piggyback and high-cost stand-alone engine managements. Professional installation and tuning by a trained technician with proper air/fuel monitoring tools are recommended, as some functions may not be compatible with certain applications. Harness kit requirements and functions may vary per application.
