Syvecs S7Plus Plug & Play ECU Kit | Toyota Supra MK4 (A80) The Syvecs S7Plus Toyota Supra MK4 Plug & Play ECU Kit is the ultimate engine management solution for the legendary 2JZ-GTE. Replacing the aging factory ECU, this kit provides motorsport-grade control over the twin-turbo or big single-turbo inline-six. Whether you are maintaining the classic sequential setup or building a 1500hp+ drag specialist, the S7Plus delivers the processing speed and logic required to maximize the 2JZ platform. Built on a triple-processor architecture with a dedicated FPGA, the S7Plus manages engine position tracking with microsecond precision. This is critical for high-RPM stability and ensures that ignition and injection timing remain rock-solid, even when running extreme boost levels. Comprehensive 2JZ & Chassis Integration The Syvecs S7Plus is designed to modernize the Supra’s electronics while respecting its heritage: Sequential Turbo Support: Advanced logic to manage the factory sequential turbocharger transition for a smooth, wide power band. Automatic Transmission Support: Native communication with the factory A340E automatic gearbox, allowing for adjustable shift points and torque-reduction strategies to protect the transmission during high-power shifts. 12-Position Map Switching: Toggle between engine calibrations (boost levels, traction strategies, or fuel types) on the fly using a 12-position switch or the factory cruise control buttons. VVTi Control: Complete, high-resolution authority over the Variable Valve Timing (on 1997+ models) to optimize spool-up and top-end power. Advanced Motorsport Features Rolling Anti-Lag: Build instantaneous boost while cruising at a steady speed—eliminating turbo lag and providing explosive acceleration for roll racing. Flex Fuel Integration: Automatic, real-time mapping adjustments based on Ethanol content (E85). The ECU scales fuel, ignition, and boost targets based on the specific ethanol percentage in the tank. Proprietary Traction Control: Advanced logic utilizing individual wheel speed monitoring to manage the 2JZ's massive torque, far surpassing any 1990s-era traction system. Staged Injection: Native support for secondary injector banks, allowing you to run 12 injectors for extreme fueling requirements on high-horsepower builds. Technical Specifications Feature Details Model Compatibility Toyota Supra MK4 (JZA80) - Non-VVTi & VVTi Engine Support 2JZ-GTE / 2JZ-GE (NA-T conversions supported) Connectivity 100MHz Full Duplex Ethernet (Fastest data transfer in the industry) Inputs/Outputs 22 x Analogue Inputs, 30 x High/Low Side Outputs Data Logging 64MB Internal Memory (Up to 1000Hz per channel) Special Features Pit Limiter, Launch Control, and Virtual Fuel Tank logic Engine Protection & Safety The S7Plus acts as a 24/7 insurance policy for your 2JZ. The ECU features sophisticated Safety Trip logic that monitors fuel pressure, oil pressure, coolant temperature, and individual cylinder knock in real-time. If a sensor value exceeds safe limits—such as a fuel pressure drop during a high-boost pull—the ECU instantly triggers a safety strategy (fuel cut or boost reduction) to prevent catastrophic engine failure.FOR MAPPING / CALIBRATION SERVICES CONTACT US HERE
