GReddy's e-Manage is a cost effective programmable engine management system that allows you to properly tune your factory engine control without having to change the entire factory ECU system to an expensive "stand-alone" unit or the inconvenience of sending it out for a full ECU reprogram. The e-Manage system is a true universal "piggy-back" type unit that taps into most Japanese factory ECU wiring, by utilizing the vehicle's existing sensors (or optional upgraded sensors if factory sensors are maxed out). The major benefit is the factory ECU settings become your "Base-MAP" for tuning. There is no need for extensive tuning for normal driving conditions, but does allow the tuner to fine tune, adjust for injector changes, and add new MAP for situations the factory ECU is not capable of (like on-boost conditions). And as technological breakthroughs are achieved, we offer FREE updates via our greddy.com website's Tech page. Basic functions will allow the tuner to slightly alter factory injector duty-cycle (± 20% at 5 preset RPM points) by intercepting and altering airflow or MAP sensor signals. An option for Honda VTEC cars will allow you to even adjust the VTEC shift point. Additional features are built into the system but are only accessible through the use of the e0-1, PRofec e-01 programmer or our PC-Windows based "e-Manage Support Tool" communication software (sold separately). There is a 16×16 airflow adjustment map, a maximum 50% larger main injector correction adjustment, upgrade air flow meter adjustment, boost limiter cut, anti-engine stall, VTEC-fuel adjustment, real-time map trace, real-time display, real-time communication and basic Data-logging. With the use of our "Optional Injector Harness" and the software, the unit has the ability to control an additional 16×16 injector duty cycle map and the controls for adding up to 2 additional sub-injectors. If the "Optional Ignition Harness" and the software are used the unit has the ability to control a 16×16 ignition timing map. All of the above maps can also be map-traced in real-time as well. If the factory range of map or airflow meter is surpassed, you can incorporate a larger airflow meter or our "Optional GReddy Pressure Sensor and Pressure Harness" to set larger scales of adjustment. All installation and tuning should only be made by a trained technician with proper air/fuel monitoring tools. (Some or all functions may not be compatible with some applications.)
