Collection: FD RX-7

ECU Recommendations for Mazda RX-7 (FD3S)

For OEM Sequential Twin-Turbo Systems:

• Vehicles equipped with the factory sequential twin-turbo setup require an S3 or Elite 2500 ECU. These options provide the necessary outputs to control the air solenoids effectively and maintain the sophisticated turbo management system.

For Single Turbo Conversions:

• If your RX-7 has been converted to a single turbo setup, the simpler S2 or 1500 ECU will meet your needs, as it requires fewer outputs to operate.

FD3S Model Compatibility:

• Series 6 (S6): 1992–1995
• Series 7/8 (S7/S8): 1996–2002
