Nexus S2 ECU Only HT-212000

The S2 replaces the Elite 1500, and the upgrade is real — same four-cylinder / two-rotor scope, but on the Nexus processing platform with a much better IO architecture behind it. Four peak-and-hold injector drivers, four ignition outputs, and the useful part: most of those can be repurposed as low-side drive outputs if your build doesn't need them all for fuel and spark.

Two things make this worth the step up from an Elite. There's an onboard wideband controller — NTK or LSU 4.9 — so you're not buying a separate controller and finding somewhere to mount it. And there are four push-pull half-bridge outputs rated 8A and PWM capable, which is enough to drive an electronic throttle directly, or a pump, or anything else that needs real current without an external relay.

Also carries automatic transmission control for common builds — Ford AODE/4R70W, GM 4L60E and 4L80E, Toyota A340E, plus Lenco and Liberty for the drag side. That's a standalone plus a trans controller in one box.

Eleven analog inputs, six synchronous pulsed inputs, USB-C connection.

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