Greddy Performance Products introduces their newest piggyback engine management system, the e-Manage Ultimate! The Greddy e-Manage Ultimate does what no other piggyback ECU can. Engineered to preserve the best features of the original e-Manage (economical price, no need for tuning from scratch, yet compatible for most Japanese performance vehicles).
GReddy E-manage Ultimate is GReddy's first PC-tunable piggyback engine management system. While retaining all of the best features of the original e-Manage, this unit sports more flexible fuel and ignition maps, the ability to switch between two different tuning maps (i.e. street tune and race tune), an increased number of input and output ports and a more comprehensive multichannel data-logging system. The additional harness taps into several tuning and data-logging sensors, including knock, water temperature, crank angle, intake air temperature and vehicle speed sensors.
The benefit of this is, the included PC-based USB "Ultimate Support Tool" allows for even finer tuning capabilities, improved flexibility in fuel & ignition control and adds impressive data-logging qualities to make tuning quicker and easier. In addition to standard e-manage airflow-based adjustments, the Ultimate version includes new and upgraded features. The Parameter Set-up, tab menu format of the Ultimate has improved direct Map control for adding and subtracting Fuel and Ignition.
There are Maps for Individual cylinder adjustment for both Fuel and Ignition. An Airflow Output Map option even allows for airflow meter elimination. And when used with a wideband A/F Meter, the Air Fuel Target Map can self-tune an Injector base tuning Map, to speed up initial tuning. To further aid in tuning, e-manage Ultimate’s improved integrated Monitoring, Map Tracing and Datalogging features far exceed any other piggyback controller on the market. Ideal for optimizing and fine-tuning for performance products like Exhaust, Air Intake, Intercoolers, Boost Controllers, and Turbochargers or Superchargers, the e-manage Ultimate fills the gaps between conventional piggyback and expensive stand-alone engine managements.
