Nexus S3 ECU Only HT-213000

The S3 is the Elite 2500's replacement — same eight-cylinder / four-rotor capability, but rebuilt on the Nexus platform. Eight peak-and-hold injector drivers and eight ignition outputs, and like the S2, any of those can be reassigned as low-side drive outputs if a build doesn't need the full count.

What separates it from the 2500 it replaces: an onboard wideband controller (NTK or LSU 4.9) built in, four 8A push-pull half-bridge outputs that can drive an electronic throttle or a pump directly, and 300 channels of logging at up to 1 kHz on 128 MB of internal memory — that last one is why it's specced as a race ECU rather than a street standalone. That's enough resolution to actually diagnose a driveline event rather than just confirm it happened.

Also handles automatic transmission control for AODE/4R70W, 4L60E, 4L80E, A340E, plus Lenco and Liberty.

This is the ECU for a 2JZ, an RB26, an LS, or a four-rotor where you want logging depth and don't want a separate wideband and trans controller in the car.

Includes the ECU, four mounting bolts, USB-C cable and dust cap, quick start guide, and wiring diagram.
