CAUTION: This is latest genuine v2.1 ELM327 scanner that uses Elm Electronics firmware. Please note, it does NOT use Elm Electronics chip, because that's expensive to license. Hence we use our own high quality chip with 100% identical functionality, speed and compatibility of Elm Electronics chip. Also, this is NOT a clone/low-quality-build as is sold 99.9% of cases on eBay.

Did you know that 99% of those cheap ELM327's on eBay (usually under $15) actually support half the data compared to High quality, genuine chip counterparts. Example, cheap eBay/Alibaba/AliExpress clones will NOT display or WRONGLY display data for: EVAP, O2 and HO2, B1S1 Lambda data parameters. While Total Car Diagnostics ELM327 cable fully shows their data in absolute accuracy. This is difference between being safe on the road — or not.

About This ELM327 USB Tool...


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).


Before going forward, please first check that your car is OBD2 compatible. Because this ELM327 interface only works on OBD2 compatible cars. Click here to check car compatibility now. (Your car MUST be OBD2 for this to work.)

P.P.S. Our ELM327 interface goes head-to-head with the fake scan tools on the market — especially those on eBay.

Because there are a lot of phony scan tools out there which are sold at very cheap prices but don't always work as advertised. For example, they have painfully slow data refresh rates. They randomly cut-off connections. And don't work with all vehicle protocols. So you're missing out on lot of valuable data from the car.

All those issues are taken care of in this new v2.1, ELM327 reader. It's fast, reliable and trusted by thousands of professional automotive technicians. It's also backed by our exclusive 1-year warranty.
