Syvecs S-GDI Plug & Play ECU Kit Toyota Yaris GR

Syvecs S-GDI Plug & Play ECU Kit | Toyota GR Yaris (G16E-GTS)

The Syvecs S-GDI Toyota GR Yaris Plug & Play ECU Kit is the world’s most advanced engine management solution for the G16E-GTS three-cylinder engine. As the factory Toyota ECU remains heavily locked to traditional tuning, this Syvecs standalone kit provides a complete replacement that unlocks the true potential of the platform. It is the definitive choice for both high-performance road cars and professional rally teams (as used in the GR Yaris Rally Cup).

Built on a triple-processor architecture with a dedicated FPGA, the S-GDI manages the GR Yaris's complex Gasoline Direct Injection (GDI) and Port Injection systems with microsecond precision. This hardware is essential for mastering the high-pressure fuel pump (HPFP) timing, electronic wastegate control, and the aggressive transients of the 1.6L turbocharged engine.

Advanced AWD & Chassis Integration

The GR Yaris is defined by its GR-Four AWD system; the S-GDI is engineered to master it:

• Live Torque & AWD Control: The S-GDI allows for live tuning of engine torque limiters and AWD operation. It monitors AWD duty and temperatures to ensure the rear-drive unit remains effective under extreme use.

• Secondary AWD Controller Support: For those seeking the ultimate in handling, the S-GDI integrates seamlessly with the optional Syvecs Standalone AWD Controller, enabling custom RWD-bias maps and "Burnout Mode."

• OEM Drive Mode & Cruise Control Integration: Switch between engine maps, boost levels, and traction strategies on the fly using the OEM Cruise Control buttons.

• Factory Dash Feedback: Ethanol content (Flex Fuel) and current calibration (Map) positions are displayed directly on the factory instrument cluster.

Performance & Motorsport Features

• Dual Injection Mastery: Native control of both Direct and Port injection, supporting up to 6 injectors total—ideal for high-horsepower builds requiring secondary fueling.

• Rolling Anti-Lag: Build instantaneous boost while cruising at a steady speed. Activated via the Cruise Cancel button, it provides explosive acceleration for roll racing or track overtakes.

• Flex Fuel Integration: Automatic, real-time mapping adjustments based on Ethanol content (E85/Pump gas), with dynamic scaling for boost, ignition, and fueling.

• Motorsport Traction Control: Advanced logic utilizing individual wheel speed monitoring, lateral-G, and GPS speed with 4 programmable target slip maps.

Technical Specifications

Engine Protection & Safety

The S-GDI acts as a laboratory-grade insurance policy for your G16E-GTS engine. It features sophisticated Safety Trip logic that monitors critical parameters in real-time. If a sensor value exceeds safe limits—such as a drop in fuel pressure or excessive crankcase pressure—the ECU instantly triggers a safety strategy (fuel cut or boost reduction) to prevent catastrophic engine failure.
