Run Pump Gas, E50, E85, or Full Ethanol — Without Changing Your Tune Every Time You Fill Up

One fuel system. Multiple fuel options. Automatic ethanol compensation.

Imagine pulling into a gas station and filling your Infiniti Q50 or Q60 with whatever ethanol blend is available — without manually testing ethanol content, calculating fuel mixtures, or switching between different ECU maps.

With the AMS Performance CAN Bus Flex Fuel Kit, that's exactly what your VR30DDTT can do.

Whether you're running regular pump gasoline, E50, E85, E98, or any mixture between 0% and 100% ethanol, this system measures ethanol content and communicates it to your vehicle's ECU.

When paired with a properly configured EcuTek flex fuel calibration, your ECU can automatically adjust fueling, ignition timing, and boost targets based on the actual ethanol percentage in your tank.

Fill up. Drive. Let your ECU handle the adjustments.

No more guessing your ethanol percentage. No more manually changing maps every time you switch fuel blends.

Stop Guessing What's in Your Fuel Tank

Your Ethanol Percentage Changes. Your Tune Needs to Account for It.

E85 doesn't always contain exactly 85% ethanol.

Actual ethanol content can vary depending on the station, season, and fuel supply.

If you're running a fixed ethanol tune, changing fuel blends without adjusting your calibration can create problems.

Here's the challenge with traditional ethanol tuning:

• You may need to manually test ethanol content before filling up.

• Different ethanol percentages require different fueling calculations.

• Ignition timing and boost targets may need adjustment.

• Switching between pump gas and ethanol can require changing maps.

• Incorrect fuel assumptions can create unsafe operating conditions.

For a high-performance VR30, accurate fuel composition information is essential.

There's a Better Way.

The AMS CAN Bus Flex Fuel Kit continuously measures ethanol content and provides that information to your ECU.

With the correct EcuTek calibration, your vehicle can automatically compensate for changes in fuel composition.

That means more flexibility, less guesswork, and the ability to optimize your engine's performance for the fuel you're actually running.

How the AMS CAN Bus Flex Fuel System Works

Advanced Technology That Works Automatically in the Background

The AMS system uses an ethanol content sensor, proprietary CAN Bus electronics, and EcuTek ECU integration to create a seamless flex fuel solution.

Step 1 — Fill Up With Your Preferred Fuel

Choose pump gasoline, E50, E85, or another ethanol blend within the system's supported range.

Step 2 — The Sensor Measures Ethanol Content

The ethanol content sensor determines the percentage of ethanol flowing through the fuel system.

Step 3 — AMS CAN Bus Electronics Communicate With Your ECU

The AMS CAN Bus module transmits ethanol information through the vehicle's CAN network.

Step 4 — Your EcuTek Calibration Makes the Adjustments

Your properly configured ECU calibration can automatically adjust fuel delivery, ignition timing, and boost targets based on the measured ethanol content.

Step 5 — Enjoy Your Drive

Once professionally installed and calibrated, the system operates automatically without requiring you to manually calculate ethanol percentages or switch maps for normal fuel blend changes.

More Than a Flex Fuel Kit — Advanced Engine Monitoring & Protection

Three Additional Analog Inputs for Custom Monitoring and Failsafes

One of the biggest advantages of the AMS CAN Bus Flex Fuel Kit is its ability to do more than simply measure ethanol content.

The proprietary AMS CAN Bus module provides three additional 0–5V analog inputs for aftermarket sensors.

These inputs allow your tuner to monitor additional engine parameters through compatible ECU software.

Monitor Critical Engine Conditions

Fuel Pressure

Monitor fuel system pressure and configure appropriate safeguards if pressure falls outside the desired operating range.

Coolant Pressure

Monitor cooling system pressure to help identify abnormal operating conditions.

Exhaust Backpressure

Track exhaust pressure for additional insight into turbocharger and engine performance.

Crankcase Pressure

Monitor crankcase pressure, particularly useful on high-horsepower or heavily modified engines.

Additional 0–5V Sensors

Integrate other compatible aftermarket sensors based on your build requirements.

Custom ECU Failsafes

With compatible sensors and proper EcuTek configuration, your tuner can establish custom failsafe strategies when monitored values exceed programmed limits.

This additional functionality can help protect your investment by allowing the ECU to respond to abnormal operating conditions.

Additional sensors are not included unless separately specified. Monitoring and failsafe functions require compatible sensors and ECU calibration.
