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...
You see, we started out using cheap EML327 clones back in 2011 for our own shop diagnostic needs. But unfortunate pattern quickly emerged...
They were produced by different non-standardized companies using different chip manufacturing process. Meaning no ELM327 USB Cable scanner was the same.
For 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. Usually cutting support for many Ford, BMW, GM, etc. models. This is just one example.
So this non-standardized situation consistently produced unreliable data you just couldn't trust. And one can't afford this with a car that needs repairs for sake of drivers safety.
So Total Car Diagnostics decided to analyze them all. The clones and original ELM327. And went on a mission to create a universal ELM327 USB Cable scanner that includes benefits and strengths of them all - combined together.
No Windows drivers hassle, no over-voltage burnouts, no haphazard car support!
And so the result...
Our ELM327 USB scanner works on 99.9% of today's cars — yes, even yours.
Simply plug one end into your car's OBD-II port, and other end into the laptop. Install one file for drivers and that's it.
Now launch any OBD software - click "Connect", and you're in!
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).
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.
(Yes, it supports manufacturer systems as long as your OBD software supports them too. But they all support Engine and Transmission.)
In addition, our ELM327 USB scanner can read numerous car data/parameters that handheld scan tools can't. Combined with powerful OBD software — you'll be able to read up to 15,000 possible data parameters from you vehicle(s).
