AlphaECU Plug-in for Nissan S15
Take complete control of your Nissan S15 with the AlphaECU Plug-in. Designed for serious builds, this engine management system provides the stability, headroom, and advanced features needed to push your SR20 or KA24 to the limit without cutting your factory wiring.
Designed to interface directly with the factory Nissan harness, this standalone ECU replaces the stock unit. Important Note: This is a "Plug-in" system. It is a fully standalone ECU that requires professional tuning once installed, ensuring it is perfectly calibrated for your specific setup.
We strive to retain major factory functions like AC and the gauge cluster. However, please be aware that we cannot guarantee every single minor factory quirk will operate exactly as stock.
