This piggyback ECU from GReddy is supposed to be universal and wires into the stock ECU, like Apexi's S-AFC. It makes fuel adjustments, but only in the range of +/- 20%, unlike the S-AFC's +/- 50% range of fuel adjustment. Where it shines is that it can control ignition timing, control addtional fuel injectors, control larger aftermarket fuel injectors and some other functions that can be useful for people going turbo or s/c. It also has a built-in VTEC controller, but I don't think that will help us with VVTLi. It remains to be seen how much control (if any) this can have over VVTi or Lift. The catch is alot of those higher functions can only be accessed by authorized GReddy dealers with the correct software. It retails for slightly less than the S-AFC.

e-Manage (piggy-back fuel computer)
e-Manage is an inexpensive programmable fuel management system that allows you to properly tune your factory fuel system, without having to change the entire factory ECU system to an expensive "stand-alone" unit. The e-Manage system is a universal "piggy-back" type unit, which taps into most factory ECU wiring and it still utilizes the existing sensors. Basic functions will allow the user to slightly alter factory injector duty-cycle(± 20% at 5 preset RPM points), by intercepting and altering airflow or MAP sensor signals. For VTEC cars you can adjust the VTEC shift point.
Additional features that are built into the system, but are only accessible though the use of our PC-Windows based "e-Manage Support Tool" communication software (Please see our Authorized GReddy Support Dealers for more information) are a 16x16 Airflow Adjustmemt Map, 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 16x16 Injector duty cycle Map and the Controls for adding up to 2 Addional Sub-injectors. If the "Optional Ignition Harrness" and the software is used the unit has the ability to control a 16x16 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 incorperate our "Optional GReddy Pressure Sensor and Pressue Harness" to set larger scales of ajustment.
All installation and tuning should only be made by a trained techntion with proper Air/Fuel Monitoring tools.
