AC STAG 300 Q-MAX BASIC ECU 8 CYLINDERS

AC STAG 300 Q-MAX BASIC ECU 8 CYLINDERS, W1Y-0300-8-QMB

The AC STAG 300 Q-MAX BASIC ECU 8 CYLINDERS is an automotive LPG system controller designed to manage engines with up to 8 cylinders that use indirect fuel injection. Part of the Q-generation series by AC Stag, this ECU combines advanced technical features with a cost-effective design to support efficient LPG conversion on suitable petrol engines.

Key Features and Functionality

This model integrates the ISA3 Autoadaptation System, which adjusts the fuel injection mapping in real time based on received petrol injection pulses. Unlike rpm-dependent methods, this system provides precise corrections that enhance engine performance under varied operating conditions.

The controller supports configuration and diagnostics through the AC STAG software suite, allowing professional tuning and maintenance. Additionally, it can be monitored and partially controlled via mobile applications like StagMobile and GasComputer, providing flexibility and convenience.

Compatibility with previous STAG-300 ISA 8 ECU models allows for direct replacement using a plug & play approach without needing changes to the vehicle's wiring harness, facilitating straightforward upgrades.

ISA3 Autoadaptation System Details

• Employs a specialized correction map that operates independently of rpm-based injection pulse corrections.
• Accurately acquires reference petrol injection maps, factoring in engine temperature variations for precise fuel management.
• Identifies engine operation modes in real time, distinguishing between closed loop and open loop control states to optimize injector timing.

Installation and Compatibility

This ECU is intended as a direct replacement for earlier STAG-300 ISA models 8, simplifying installation by using existing wiring harnesses. It supports 8-cylinder engines with indirect fuel injection, making it suitable for larger petrol engines equipped for LPG conversion.

Certifications and Warranty

The device carries a comprehensive warranty, the longest available from the STAG range, highlighting its manufacturing quality and reliability.

With its advanced adaptation features, mobile app compatibility, and straightforward installation, this ECU offers a balanced solution for users seeking modern LPG technology for 8-cylinder petrol engines.
