SFI4 – Supplemental Fuel Injection via CAN

This controller will allow you to control 4 fuel injectors over CAN Bus, specifically designed for use with the DS1 on Audi 4.0 TFSI engines which need help with supplemental fuel injection.

• 4 saturated low side fuel injector outputs, for use with high impedance injectors only. May run multiple injectors per output, supported modes are sequential, semi sequential, or batch
• Uses crankshaft and camshaft sensor inputs to synchronize fuel injection events to the engine cycle
• 4 analog inputs with individually adjustable filtering
• 4 digital frequency or discrete inputs with software selectable pull-up resistors
• All sensor readings and commands are transmitted via CAN Bus, custom code and/or custom tuning is needed to make this controller work
• Field updatable firmware updates via USB cable and Windows software
