Haltech Nexus S3 Plug 'n' Play ECU and Adapter Harness Kit - Mazda RX7 FD3S (Series 6)

The Haltech Nexus S3 Plug 'n' Play Adapter Harness Kit (HT-213307) gives you a complete ECU upgrade for a Mazda RX7 FD3S S6, using the factory ECU connectors so you avoid cutting or splicing the original harness.

Inside the ECU you get 8 x peak/hold injector drivers (also usable as low side drive outputs), 8 x low current ignition outputs (also usable as low side drive outputs), 6 x low side drive outputs (PWM capable, DPOs), 4 x push-pull/half bridge outputs (8A, PWM capable, for example for electronic throttle), 1 x ECR output, 11 x 0-5V analog inputs with redundancy for electronic throttle and switchable 5V pullup, trigger and home inputs with differential inputs, adjustable thresholds and glitch filters, and 6 x synchronous pulsed inputs (zero crossing or adjustable thresholds) for cam sensor inputs, frequency inputs or 0-5V analog inputs. An on-board wideband controller supports NTK and LSU 4.9 sensors, backed by an on-board 4 bar MAP sensor, 2 x CAN ports with switchable termination, and onboard data logging of up to 300 channels at sample rates up to 1ms (1kHz) with 128MB of internal memory. You connect the kit directly to the factory harness and get the ECU running within a few hours, guided by the quick start guide.
