Elite 1500 + Nissan 200SX/Silvia S15 & S14A S2 Plug ‘n’ Play Adaptor Harness Kit

SR20DET Precision: Elite 1500 Kit for S15 & S14A

Take control of your SR20DET with the Elite 1500 + Nissan 200SX/Silvia S15 & S14A Plug ‘n’ Play Adaptor Harness Kit. This package is the ultimate tuning solution for the S15 and S14A “Kouki,” combining the advanced features of the Elite 1500 ECU with a seamless plug-in harness. It replaces the aging factory ECU, giving you the power to tune for larger turbos, bigger injectors, and alternative fuels with motorsport-grade precision.

Engineering for the Modern SR20

The Elite 1500 is perfectly sized for the 4-cylinder SR20DET, offering 4 injection and 4 ignition drivers for full sequential control. The adaptor harness connects directly to the factory loom, routing all critical signals—including the optical CAS, VCT solenoid, and knock sensor—to the ECU. The kit includes an intake air temperature sensor for a reliable Speed Density conversion, eliminating the MAF sensor restriction. The Elite 1500’s advanced knock control and engine protection strategies provide peace of mind when pushing the limits of the SR20.

Operational Benefits

This kit allows for complete customization of the engine’s operation. You can enable features like launch control, flat-shift, and anti-lag. The Elite 1500 supports flex-fuel, allowing you to run E85 for cooler combustion and more power. The harness ensures that factory dash functions like the tachometer and coolant temp gauge remain operational. It is the comprehensive solution for any serious S15 or S14A build.
