RX7.COM | FD ECU

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 control over fuel and ignition timing as well as cooling fans, rev limiterand more. This unit is not a “piggy back” device, it is a full stand alone system. The Power FC can be programmed through a laptop computer (with the FC-Datalogit sold below) or the “FC Commander”, a hand held keypad with a large display screen. You can use the FC-Datalogit or the FC Commander to program the Power Fc or to monitor engine sensors (air temp, water temp, RPM, boost pressure, knock sensor, oxygen sensor, voltage , 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 more complicated systems which require rewiring of the engine, this is a true "plug and play" solution. By upgrading to this, more advanced, engine computer you can experience improved driveability, increased reliability and more power. This upgrade really does offer the best of all worlds. You can save maps or load previous saved maps from a laptop by using the optional FC-Datalogit system. Basic programming can be done through the FC Commander keypad, while full programming and complete access is through the FC-Datalogit system. The Power FC makes an excellent system for a daily driven RX-7 or track car. 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 before we ship out your system to allow for an easy "plug in and start" installation. Please include full list of modifications when placing the order in the “Comments” section.

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 fuel economy. Replacing this part every 30,000 miles will keep this from ever becoming an issue. Some 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 A’PEXi plugin 3 bar Map sensor is a much easier option when it comes to increasing the ECU's ability to read boost. The sensor plugs into the original Mazda harness and requires only a simple calibration change that can easily be done through the commander. Just like the GM unit, the A’PEXi sensor reads up to 29psi.
