The FD3S minor changes… The new RX-7 FD3S, which succeeded the previous RX-7 FC3S after its much-lamented retirement, was released in October 1991. It has since evolved through three minor updates. The third brought major changes comparable to an FC3S facelift; the powertrain received changes so extensive they amounted to an almost complete model change.
Parts with changed compatibility: 4BEAT-FD (sports computer): ECU changed; FCDF Type N (fuel-cut prevention part): ECU changed; FCDF Type D (fuel-cut cancellation type): ECU, pin arrangement and connector changed; SCA (Sequential Throttle Controller Adapter): pin arrangement and connector changed; EBS III-FD (FD3S boost controller): cannot be used with SCA; 305 speedometer: illumination changed from amber to green; boost hose kit: intake-valve shape changed; racing cord / NGK Type II high-tension cord for racing plugs: ignition-coil wiring arrangement and cord shape changed.
If the Fuel Cut Defencer Type D4 is used by itself, it sends a lower boost reading to the ECU, causing the ECU to try to raise boost. Examples: 1) With the standard muffler, boost can reach 1.0 kg/cm² on the primary side in 4th gear. 2) With a road-legal muffler (FD763 Big Bore End), it can reach 1.1 kg/cm² on the primary side in 5th gear. 3) With a straight-through catalytic section and a road-legal muffler after the catalyst (replacement converter and FD763 Big Bore End), it can reach 1.2 kg/cm² on the primary side in 5th gear. These figures show that the Fuel Cut Defencer Type D4 and EBS III-FD4 must always be used together.
The boost settings above are only guidelines and are close to safe values for full-throttle running through 5th gear. Differences between individual cars and operating conditions may mean a higher setting is safe—or that even these settings are dangerous. During a high-speed trial, close the windows, turn off audio equipment, and listen for knocking. If knocking (an abnormal sound from the engine) occurs, promptly lift off the accelerator.

2. Speedometer: A 305 speedometer compatible with the change in the standard meter illumination from amber to green is now available. As of November 1996, testing is still underway to identify any problems associated with cancelling the 180 km/h limiter.

3. Boost cut: At certain boost pressures, depending on gear and engine speed, fuel injection to the rear rotor is stopped. Examples of boost cut are shown below.

This raises maximum output by 10 PS over the previous model, to 265 PS at 6,500 rpm (NET). Some existing parts are no longer interchangeable. The main changes and reasons are listed below.
The boost cut can currently only be cancelled by installing a Fuel Cut Defencer Type D4. 4. Rev limit: Above approximately 8,100 rpm (MT) or 7,500 rpm (AT), fuel injection to both rotors stops. There is currently no way to cancel it. 5. Boost control:

1. Speed limiter: Above 180 km/h, fuel injection to both rotors stops. At present, cancellation is done by cutting a wire: cut the green/red wire at the fifth position from the top of the right-hand row of the 34-pin connector connected to the ECU. It can also be cancelled by installing the newly developed Fuel Cut Defencer Type D4.
