Nexus S2 Plug ‘n’ Play Adapter Harness Kit – Mazda RX7 FD S7 & 8

Nexus S2 Integration Kit: Late FD Solution

The Nexus S2 Plug ‘n’ Play Adapter Harness Kit is the complete entry point for integrating the Haltech Nexus S2 VCU into the Series 7 and 8 Mazda RX-7. This kit bundles the Nexus S2 unit with the specific adaptor harness required for the late-model 13B-REW. It is an ideal solution for single-turbo conversions looking for modern management.

Engineering for the Nexus S2

The Nexus S2 provides robust control for the rotary engine. The adaptor harness connects to the 4-row factory header, managing ignition, injection, and metering oil pump functions. The kit includes an air temp sensor for Speed Density tuning. The S2’s onboard wideband controller (sensor required) and data logging are fully accessible.

Operational Benefits

This kit simplifies tuning and offers advanced features like launch control and boost control. The plug ‘n’ play installation is quick and reversible. Note that due to I/O limitations, the Nexus S2 is best suited for single turbo setups on the FD; retaining the sequential twin system requires the Nexus S3.
