The ELM 327 OBDII interface offers extensive vehicle data logging and sensor monitoring capabilities. This article explores the installation and functionality of an ELM 327 OBDII device, focusing on a simple modification to ensure a discreet installation. Initial findings reveal a boost spike of around 20 psi and rich air-fuel ratios (AFR) under wide-open throttle (WOT) conditions. Further data logging and analysis will provide a more comprehensive understanding of vehicle performance and potential areas for improvement.
Understanding the Power of Interfuse OBDII
An OBDII (On-Board Diagnostics II) port allows access to a wealth of real-time vehicle data. Utilizing an ELM 327 OBDII adapter with a smartphone app like Torque unlocks the ability to monitor everything from engine RPM and AFR to boost pressure and various other critical sensors. This readily available technology empowers vehicle owners with valuable insights into their car’s performance.
Installing Interfuse OBDII: A Stealthy Approach
While the ELM 327 Interfuse Obdii adapter plugs directly into the OBDII port, sometimes the fuse box cover interferes with a clean installation. In this case, a minor modification to the fuse box cover allows for seamless integration. A simple notch cut into the underside of the cover, where it obstructs the installed adapter, solves the problem. This modification is completely invisible from the outside, maintaining the factory appearance of the fuse box.

Unlocking Data with Interfuse OBDII and Torque
The Torque app, paired with the Interfuse OBDII adapter, provides a comprehensive suite of data logging and diagnostic features. Initial data reveals a boost spike of approximately 20 psi, alongside rich AFRs of around 10.2:1 at WOT. Further analysis of these readings will help to optimize performance and potentially identify areas for improvement in fuel economy. The Torque app also allows for custom gauge displays, fault code scanning, trip logging with GPS data, and access to a wide range of sensor readings. This powerful combination provides an inexpensive yet invaluable tool for vehicle diagnostics and performance monitoring.
Conclusion: Interfuse OBDII for Enhanced Vehicle Understanding
The Interfuse OBDII interface, coupled with the Torque app, transforms a smartphone into a powerful vehicle diagnostic tool. With a minor modification for a discreet installation, accessing real-time data and logging critical parameters becomes effortless. This setup allows for informed decisions regarding vehicle maintenance, performance tuning, and potential modifications for increased power and efficiency. Future data analysis will delve deeper into optimizing performance based on the insights gained through continuous monitoring.
