When most people hear “data monitor,” they immediately think of devices that plug into the vehicle’s OBDII port. While those can be useful, they’re limited by what the factory computer can see—and more importantly, where they can be installed.
The
FASS Connect Data Monitoring System is different.
FASS Connect is a completely standalone monitoring system, designed to work independently of your vehicle’s factory computer. It doesn’t rely on an OBDII port, and it isn’t restricted to certain vehicle platforms.
Instead,
FASS Connect gives you the freedom to monitor critical system data on virtually
any application.

Built as a True Standalone Monitoring System
At the heart of the system is the FASS Connect ECU, which operates independently of any factory control modules. Installation is straightforward and flexible—the ECU simply requires:
- Power
- Ground
- Any sensors you want to monitor
That’s it.
From there, you can add sensors for:
- Fuel pressure
- Fuel filter life
- Boost
- Exhaust gas temperature (EGT)
- Temperature sensors
- Pressure sensors
- And more
Because FASS Connect isn’t tied to factory electronics, it works on
diesel trucks, gas trucks, UTVs, agricultural equipment, commercial engines, boats, generators—even helicopters.
If it runs on fuel,
FASS Connect can monitor it.
No OBDII Port Required
Traditional plug-in monitors rely entirely on the vehicle’s OBDII system, which limits both compatibility and available data. These devices can only read what the factory ECU already tracks—and they won’t work at all on applications without an OBDII port.
FASS Connect eliminates that limitation completely. Because it uses
direct sensor inputs, you get accurate, real-time data straight from the source—not filtered or restricted by factory programming.
This also means FASS Connect works perfectly on:
- Older diesel trucks
- Engine swaps
- Standalone engine builds
- Industrial equipment
- Marine and aviation applications
Where OBDII-based monitors simply cannot operate.

Wireless Data Transmission with Industrial-Grade Bluetooth
FASS Connect was engineered for reliability and ease of use. The ECU transmits data wirelessly using
industrial-grade Bluetooth, eliminating the need for bulky wiring between components.
Data can be viewed through:
- The optional FASS Connect gauge
- Or the
free FASS Connect mobile app, available on
both iOS and
Android devices
This wireless architecture keeps installations clean while providing instant access to real-time system data.
Monitor What Matters Most
FASS Connect
was built to give you complete control over your monitoring setup. Instead of being limited by factory sensors, you can monitor exactly what matters most for your specific application.
Whether you’re protecting a diesel truck, tuning a performance build, monitoring farm equipment, or managing a commercial engine, FASS Connect delivers the data you need—without limitations.
The Future of Fuel System Monitoring
FASS Connect represents a smarter, more flexible approach to engine monitoring. By operating independently of factory electronics and using direct sensor inputs, it provides accurate, reliable data across virtually unlimited applications.
It’s not just another plug-in monitor. It’s a purpose-built, standalone system designed to work wherever you need it.
