The Bosphorus Innovations Stage 3+ ECU Water/Methanol Injection Kit is engineered for advanced performance builds controlled via a standalone ECU. Fully programmable based on TPS, MAP, or engine load, it features an integrated fast-reacting solenoid valve to lock fluid in place and provide absolute safety under any routing condition.
Standalone ECU Integration: Program single-stage injection dynamically based on Throttle Position Sensor (TPS), Manifold Absolute Pressure (MAP), or overall engine load.
Solenoid Valve Safety Protection: Fast-reacting integrated solenoid locks fluid in place when idle—making it ideal for rear-mounted reservoirs, vacuum zones, or lower nozzle mountings.
Pulsation-Free High-Pressure Pump: Employs an internal bypass architecture instead of a pressure switch for a smooth, constant, and even spray pattern.
Customizable Nozzle Selection: Pick from a wide range of flow rates (95 cc to 2200 cc). (Default: 252 ml/min [4 GPH] nozzle and Red Hose if unspecified).
Bosphorus Innovations Stage 3+ ECU Water/Methanol Injection Kit (Standalone ECU & Solenoid Controlled)
Designed for professional motorsport applications utilizing standalone engine management systems, the Stage 3+ ECU Water/Methanol Injection Kit delivers maximum thermal protection and combustion control. By introducing a fine water-methanol mist into the intake tract mapped precisely to TPS, MAP, or engine load, the system drastically reduces intake manifold temperatures and exhaust gas temperatures (EGT) to protect pistons from melting while eliminating engine knock.
Advanced Solenoid & Bypass Architecture Unlike standard setups, the Stage 3+ ECU kit includes an integrated fast-reacting solenoid valve mounted directly before the nozzle. This eliminates any risk of gravity siphoning or unwanted fluid leakages. Furthermore, our high-pressure diaphragm pump utilizes an internal bypass design to eliminate fluid pulsation, supported by 100% methanol-resistant nickel-plated brass, standard brass, and EPDM-grade plastic components.
Key Benefits & Features
Combustion Efficiency: Enhances dynamic compression and burn efficiency while reducing harmful emissions (CO, CO2, NOx, and HC).
Complete Infrastructure: Includes a compact 3-liter plastic tank, controller with wiring harness, 6 meters of injection tubing, 40-micron stainless steel inline filter, and check valve.
2-Year Warranty: Backed by Bosphorus Innovations’ comprehensive guarantee against manufacturing defects.
Nozzle Selection Guide
100% Water: 10–15% Water-to-Fuel ratio or 0.5–1 cc per HP
50% Water / 50% Methanol: 15–20% Mixture-to-Fuel ratio or 1–1.5 cc per HP
100% Methanol: 20–25% Methanol-to-Fuel ratio or 1.5–2 cc per HP
(Default configuration: 252 ml/min [4 GPH] nozzle and Red Hose if no specific size/color is indicated before ordering).
