5. OBD Auto Doctor: best OBD2 ELM327 software for Linux

Operating Systems: Mac OSX10.12 or later, Windows 7 and later, any Linux

Price: Paid

OBD Auto Doctor reads both generic and manufacturer-specific OBD trouble codes (DTCs). The software will clear the all-important Check Engine Light faults and contain a massive DTC database with more than 14000 DTCs.

Emissions test data is supported, enabling the owner to resolve any issues before booking an expensive test appointment with their mechanic. 

There’s a free version, but the functionality is minimal. Even clearing the Check Engine Light faults isn’t supported. You need to buy a subscription for US$5/month or USD$20/year to access many useful features.

Alternatively, 3 Price points are available for the Pro version; Express, Standard, and Business. They cost US$39.95, US$59.95, and US$119.95, respectively. It is a single, one-off payment, not an ongoing license agreement.

Hitting the web for customer reviews reveals some similar comments. For example, the software syncs to the ELM327 quickly and easily. It met people’s expectations in all cases, and they were able to reset errors, faults, and warnings easily and with no pain.

Overall, people enjoy using OBD Auto Doctor, and it sounds like they have created a very user-friendly interface.

OBD Auto Doctor software is available for Mac OS, Windows, and Linux. (Windows 7 and later, Mac OSX10.12 or later, and any recent instance of Linux). It has the usual features I would expect, but you’ll need to buy separate scanning hardware to access your data.

There are lots of good-looking analytics features, including custom charts, graphs, and real-time monitoring displays.

If you are ready to pay for one of the full versions, this software looks great. Once you have it set up, it’s very usable, but there are issues with storing and sharing historical data, test results, and analytics. Overall, it’s a thumbs up.


  • It connects seamlessly
  • WiFi Dongle or Bluetooth connections are solid
  • There is a free version to get a flavor before you buy


  • Free version provides too few essential functions
  • No facility to upload info to a cloud service
  • Not entirely stable, with logon not possible unless scanner is connected

An overview video of OBD Auto Doctor’s features from AutoInstruct.

OBD Auto Doctor software requires a standard ELM327 adapter (USB or Bluetooth).

OBDLink LX is highly recommended.

6. LapLogger: best OBD2 ELM327 software for Mac OS

Operating systems: Windows, Mac OS

LapLogger has versions for your laptop (Mac OS, Windows) and your mobile devices (Android, iOS, Windows Mobile, Blackberry).

Again, it provides all the expected fault diagnosis and resetting functions, but this application’s real power is the suite of real-time telemetry recording and analytics features.

As the name suggests, you can use LapLogger at the race track to record and compare lap times, racing lines, and tuning strategies. It displays real-time throttle, speed, RPM, and coolant temp data, displaying the results in custom-built charts and graphs for instant analysis.

The GPS function ensures that this ELM327 software knows exactly where your device is on track at each moment, so you can compare racing strategies for each section of the circuit.

The price is low at $20 for Windows versions and $25 for Mac, and there’s even a free version with limited functionality. The free software does have the fault code reading and resetting functions activated. So it’s worth considering in its own right.

It’s worth noting that LapLogger gets more than its fair share of complaints about software stability issues. Reports of the application crashing when trying to display data in charts were common, and perusing customer reviews gave us some concerns about paying the $20.

Overall, this is an excellent application for racing and tuning fans to communicate with their vehicle’s electronic systems. The reviews stress its ease of use and reliability, so it’s an excellent deal for the money.

European customers should take a look at EOBD Facile. It has all the diagnostics and fault identification tools most people will need.

Download the free version before buying to confirm that it functions well and reads all the codes and data you require. There are versions for Macbook OS X and Windows 7, 8.0, 8.1, & 10.

  • Free trial
  • Good Value
  • Works with your current scanner


  • Targeted at the Euro market
  • Some WiFi connection issues

All ELM 327 adapters are supported, along with EM320, 320 & 323. They recommend you buy their KlavKarr hardware, but any generic interfaces will work fine. I would buy OBDLink SX for Windows if I were you.

This professional automotive diagnostic software can work with most versions of Windows, from Windows 95 to Windows 8.

10. DashCommand: best OBD2 software for OLD Windows PC laptop

Operating systems: Windows 95, 98, ME, NT, 2K, XP, Vista, and Windows 7

For the same $40 price tag, you can get a copy of DashCommand, another ELM327 compatible application, specially designed with touchscreens in mind.

It runs on Windows OS from Win95 to Win10 and includes all the usual functions like clearing the check engine light and reading and resetting trouble codes.

How does OBD2 car diagnostic software work?

OBD2 employs a network of sensors located around the engine, transmission, and drivetrain of your vehicle. This network collects and transmits data using an agreed industry protocol. The data are then analyzed to give the user a description of the car’s performance, general health, and emissions.

The OBD-II software can be downloaded from the providers’ website and installed on a laptop or PC, just like any other application. Once installed, the computer is connected to the car with either a wireless ELM327 adapter or an OBD2 physical cable.

All cars now have an OBD2 connector socket, which connects via a USB OBD2 adapter to your laptop. The OBDII USB software can capture, organize, and display this data. Some brands can also reprogram your ECU to improve efficiency and performance.

OBD2 ELM327 software buying guide

What are the benefits of OBD2 auto diagnostic software?

OBD2 diagnostic software allows the average car owner to diagnose their vehicle’s problems before taking it to the repair shop. You can test your emissions, make sure your brakes are functioning well, and clear any faults without paying your mechanic.

Some OBD2 programming software packages allow you to remap your car’s ECU chip, increasing both power and efficiency.

The most significant advantage of computer OBD2 software is it can analyze and display the data from your vehicle.

You can view the information in intuitive charts and graphs, which makes it much easier to understand. It helps you get the maximum utility from your data. Also, you can store and share your findings with a growing network of other users.

Apart from giving the motorist confidence about their vehicle’s health, the primary motivation for using OBD software is saving time and money. You can avoid expensive, time-consuming, and sometimes wholly unnecessary trips to your service mechanic.

It’s becoming essential for a professional mechanic to present data analysis to the customer in an understandable and widely shared format. Having all the metrics stored and easily accessible helps the pro-mechanic provide the best customer service.

Typical prices and updated information

There’s a range of price points from the low hundreds to thousands of dollars. Most offerings have several options, from free basic options and free trials to paid, full versions.

The prices vary between hobbyist systems and professional setups. Some packages come with proprietary OBD-11 scanners and cables; others are software only.

Operating system requirements

Not all OBD2 software packages for laptops are compatible with all the major operating systems (Windows, Mac, or Linux).

It’s essential to ensure that your intended device and operating system (OS) are supported before deciding to buy.

I will look carefully at this for each product I consider.

Vehicle coverage

Although OBDII generates data according to an agreed industry standard, at least five popular protocols may apply. Different software packages cover different makes of vehicles.

So it’s essential to buy the software that will meet your present and future requirements. 

Free versions Vs. paid Versions

Most software providers will release a free version with basic functionality. They enable the full version once you decide to hand over your cash. You’ll need to weigh up the functions you require against the price you’re willing to pay.

I’ll look at the purchasing options for each of the products I include in this post.

Key features an OBD-II software package should have

No two systems are the same, but some essential functions are common to all OBDII software. The most critical needs for most amateurs are the Check Engine Light, error codes, and resets. All the following OBD2 scanner software packages have these capabilities. Standard features include:

  • Real-time data collection – to assess current performance
  • Fuel consumption and mileage information
  • Check Engine Light diagnostics
  • Preparedness test for emissions
  • Freeze frame – this records the engine state at the time a fault occurred
  • Intuitive graphs and charts present and compare data
  • Fault code identification – there are thousands, which all need decoding
  • Fault code clearing – once resolved, this resets the fault and the warning light, and so much more

Final thoughts 

With my list of the best ELM327 OBD2 software package, I am confident that you’ll pick the right one for you.

When looking for car diagnostic software, the first thing to consider is your requirements.

People’s requirements vary according to their circumstances, so the most effective options for a professional mechanic may be different from those of an experienced hobbyist or home tinkerer.

Aside from a wide range of prices, this software niche varies significantly in the functions they include.

There’s considerable variation in the prices, licensing terms, update schedules, and other fees. The most expensive is not always the most suitable, however. Some products come bundled with scanners, cables, software, access to technical information libraries, and direct customer support.

If it’s still hard for you to choose, here are my top choices:

  • TOAD Pro: Best OBD2 programming software for Windows – for experienced enthusiasts and professional mechanics.
  • OBDwiz: Best Free OBD2 ELM327 software full version for laptop/PC – for ordinary car owners.


Q. I am not a technical person. Will I be able to understand the laptop OBD2 software?

Q. Will PC OBD2 software save me money?

A. Generally yes. You will make fewer trips to your mechanic.

Q. Can I reprogram my car’s ECU with OBD-2 software for PC, and is it legal?

Q. Can I measure performance with OBD-II software?

A. Yes, you can accurately assess your 0-60mph times and calculate your optimum fuel consumption. There are several performance-related analytics and diagnostics.

Q. Will my PC or Laptop run OBD2 diagnostic software?

A. As long as you have a recent version of Windows or OSX, then there will be a package for you. You need to confirm which version you require when you download.

Q. How do I install OBDII software on my computer?

A. The same way you install other software – you download it from the website then follow the installation instructions.

Q. Can I try the software for free?

A. In some cases, yes. For example, Toad Pro does not offer a free trial, but Touchscan and OBD Auto Doctor both do. You should check out their websites for details.

Q. Does it matter what car I own?

A. No, all recent cars are compatible with OBD2 diagnostic software. You may need a software add-on, depending on whether you are in Europe or the US.

Q. Where can I learn about OBD2 scanner software?

A. Some providers organize online training courses and offer technical libraries. There are lots of Youtube videos to watch for both beginners and experts. There are also large online communities of users, and plenty of forums if you need advice.

Q.  Will using OBD2 software invalidate my warranty?

A. This is a very important question. If your car is still under warranty, you need to check with your warranty plan provider.

Q. So which software should I buy?

A. This depends on your circumstance. For a professional setup try AutoEnginuity. If you are a novice, try one with a free trial, or a fee basic version. There is something for everyone.
