Ultimate Rotary Control: Elite 2500 Kit for FD RX-7 S7/S8
The Elite 2500 + Mazda RX7 FD3S-S7&8 Plug ‘n’ Play Adaptor Harness Kit is the premier engine management solution for the late-model RX-7. This package pairs the powerful Elite 2500 ECU with a bespoke harness, enabling full control over the 13B-REW’s complex systems, including the factory sequential twin turbos.
Engineering for Twin Turbo Rotary
The Elite 2500 offers enough I/O to manage the FD’s sequential turbo solenoids, MOP, and fans without compromise. The adaptor harness connects seamlessly to the 4-row factory header, preserving the OEM wiring. It supports advanced features like drive-by-wire (if retrofitted), knock control, and flex-fuel. The kit facilitates a move to Speed Density tuning for better response.
Operational Benefits
This kit provides the tuner with total control. The Elite 2500’s advanced logging and protection strategies are vital for high-power rotary builds. The plug-and-play nature ensures a reliable install that can be reverted to stock if needed.
