Combined with powerful OBD software - you'll be able to read up to 15,000 possible data parameters from you vehicle(s). In addition, our ELM327 USB scanner can read numerous car data/parameters that handheld scan tools can't. But they all support Engine and Transmission.) (Yes, it supports manufacturer systems as long as your OBD software supports them too. What's more - our scanner will give you 'dealer level' diagnostic power on your vehicle - allowing you to perform advanced diagnostics, health checkups and fault analysis on systems beyond generic OBDII systems of just Engine and Transmission. You can now begin to diagnose vehicle problems, reset faults, tap into performance statistics - and basically see everything you ever wanted to know about the inside of your vehicle(s). Now launch any OBD software - click 'Connect', and you're in! Install one file for drivers and that's it. Simply plug one end into your car's OBD-II port, and other end into the laptop. Our ELM327 USB scanner works on 99.9% of today's cars - yes, even yours. No Windows drivers hassle, no over-voltage burnouts, no haphazard car support! And went on a mission to create a universal ELM327 USB Cable scanner that includes benefits and strengths of them all - combined together. So Total Car Diagnostics decided to analyze them all.

And one can't afford this with a car that needs repairs for sake of drivers safety. So this non-standardized situation consistently produced unreliable data you just couldn't trust. Usually cutting support for many Ford, BMW, GM, etc.

Meaning no ELM327 USB Cable scanner was the same.įor example, some had faster refresh rates (despite same baud of 57,600 bps) - but expense of lacking PWM J1850 OBDII protocol - meaning it excludes support for over 40% of world's OBD2 cars. They were produced by different non-standardized companies using different chip manufacturing process. You see, we started out using cheap EM元27 clones back in 2011 for our own shop diagnostic needs.

First a quick story how and why we invented the standardized ELM327 USB scanner - that's now used by large car companies and professional mechanics who need maximum connection reliability, trustworthy data and extensive car compatibility.
