Unlock the full potential of flex fuel tuning with the AMS Universal Flex Fuel CAN Bus Box. Designed to give you the freedom to run pump gas, E50, E85, E98, or any ethanol blend in between, this versatile unit makes building your own DIY flex fuel system simple and reliable. Housed in a dust and water resistant IP54-rated enclosure, the CAN Bus Box integrates seamlessly with your ECU to deliver real-time ethanol content data while offering up to three additional 0-5v analog inputs for critical monitoring and failsafe setup. Wherever you plan to mount the CAN Bus Box, the included universal harness minimizes wiring complexity with over 8 feet of flame-retardant, XLPE-sleeved wiring for durability in demanding environments. Complete with CAN protocol information and pinout documentation, the AMS Universal CAN Bus Box is the foundation of a powerful, flexible, and future-proof fueling solution.

Factory CAN Bus Integration

With the AMS Universal Flex Fuel CAN Bus Box, our engineers have developed a solution that integrates directly with your vehicle’s factory CAN bus protocol. Unlike hijacking a signal from an existing system, this design enables seamless OEM-level communication with the ECU. The CAN Bus Box also provides up to three additional 0–5v analog inputs, giving your tuner the ability to monitor critical parameters such as coolant pressure, fuel pressure, exhaust backpressure, crankcase pressure, or various other aftermarket 0-5v analog sensor inputs if they so choose. With support across many ECU calibration platforms, these inputs can be tied to custom failsafes that automatically trigger if a sensor reading falls outside the safe range. By allowing conditions such as over-pressure or under-pressure to activate protective measures, the system delivers an added layer of engine protection and peace of mind. These safety enhancements give you the confidence to push your build while enjoying the convenience and flexibility of the AMS Performance Universal Flex Fuel CAN Bus Box.

Product Notes

• ECU calibration software must have configurable CAN datastreams. Some software is locked down and will not allow for manipulation of CAN protocol (i.e. Cobb Accessport). Check with your calibration software manufacturer to confirm CAN datastream configurability before purchase.
• This is not a complete Flex Fuel kit. Fuel lines, fuel fittings, brackets, mounting hardware, ethanol content sensor, and ECU calibration software & hardware are not included.
• 65″ power wire, 48″ twisted CANBUS wiring from module to unterminated ends, 48″ from CANBUS module to Flex Fuel Sensor connector.
