For those serious about RX-7 performance, looking for more power and more precise tuning we also offer two stand alone ECU systems, the Haltech and the PowerFC. Stand alone ECUs are only recommended for the more advanced tuners, those with experience, with access to a dyno and a wide band air-fuel meter.

The Power FC replaces the original Mazda computer completely and allows full fuel and ignition timing control. This unit is not a “piggy back” device, it is a full stand alone system. The Power FC is programmed through the optional “FC Commander”, a hand held keypad with a large LCD screen display. The FC Commander can be used to program the fuel and ignition setting of the Power FC or to monitor engine sensors (air temp, water temp, RPM, boost pressure, knock sensor, oxygen sensor, injector duty...).

The entire installation of the ECU consists of unplugging the original ECU from the car and plugging in the Power FC. That’s IT! No other wiring is necessary. Unlike the Haltech system which is more suitable for a purpose built race car. You can save maps or load previous maps from a disk only by using the optional FC-Datalogit system. Basic programming can be done through the FC Commander keypad, while full programming and map access is through the FC-Datalogit system only. The Power FC does make an excellent system for a daily driven RX-7. Both Power FC and FC Commander include user manuals in English.

All PowerFC units that we sell comes with full technical support for the product. This includes, but is not limited to, uploading a basemap for your particular application. Please include full list of modifications when placing the order in the “Comments” section. PowerFC and FC Commander unit shown.

We are now proud to present the FC-Datalogit system to the North American market. Developed and manufactured in New Zealand, the FC-Datalogit enables the driver/tuner to harness the full performance potential of the PowerFC. Don’t let the name fool you, the FC-Datalogit system enables complete tuning and datalogging using a laptop computer. With full access to base maps and all correction tables, this system is a must for anyone who wants to take a PowerFC-controlled vehicle to the next level. Check out the manufacturer website Here.

The FC-Datalogit system is powerful and flexible enough to accomplish almost anything and includes full manufacturer’s support through a Yahoo E-Group. The FC-Datalogit is designed to be used with your laptop's serial port but can be connected to a USB port using the optional USB adapter Shown with optional USB adapter.

Sorry about the old image, current datalogits are black. The USB adapter comes with software on CD not disk.

MAP (manifold absolute pressure) sensor in a factory 3rd Generation RX-7 cannot see past 17psi. Using a 3 Bar MAP sensor will allow the computer to map engine management strategy up to 29psi. Note: to be used only with A’PEXi PowerFC or Haltech ecus. PowerFC requires special programming, call for details.

Tired of poor mileage on your RX-7? Here’s a solution. The oxygen sensor is out of sight and out of mind. On many cars, it has never been replaced. Unfortunately, O2 sensors lose accuracy with time and eventually ends up hurting gas mileage. Replacing this part every 30,000 miles will keep this from ever becoming an issue. Many have seen improvements of as much as 8mpg. Our replacement is a direct fit and saves about $100 over the Mazda unit. Buy one today and save!

The GReddy 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.

Additional features that are built into the system, but are only accessible though the use of a Windows based “e-Manage Support Tool” communication software are: a 16x16 Airflow Adjustment 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 an “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 Additional Sub-injectors. If the “Optional Ignition Harness” 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 incorporate the “Optional GReddy Pressure Sensor and Pressure Harness” to set larger scales of adjustment.
