Elite 2500 + Mazda RX7 FD3S-S6 Plug ‘n’ Play Adaptor Harness Kit

Twin Turbo Control: Elite 2500 Kit for FD RX-7 Series 6

The Elite 2500 + Mazda RX7 FD3S-S6 Plug ‘n’ Play Adaptor Harness Kit is the premium solution for Series 6 (1992-1995) RX-7 owners who want to retain the factory sequential twin-turbo system or demand the highest level of control for a single turbo setup. This kit pairs the Elite 2500 with a S6-specific harness.

Engineering for the S6 13B-REW

The Elite 2500 provides the necessary I/O to fully manage the complex sequential turbo solenoids and the Metering Oil Pump (MOP) of the S6 FD. The adaptor harness connects to the 2-row factory ECU header. It supports advanced features like DBW (with retrofit), flex-fuel, and extensive logging. Speed Density tuning is enabled via the included air temp sensor.

Operational Benefits

This kit offers total control over the rotary engine’s parameters. It is the only plug ‘n’ play option in the Elite range that supports the S6 twin-turbo system correctly. The installation is reversible and robust, maintaining the character of the FD while adding modern reliability and performance.
