Best OBD2 Programming Software Reviews 2021

OBD2 scanners and software are the most reliable and versatile way to diagnose problems with a vehicle. These tools scan your car’s system to identify existing and potential issues. As many car owners know, just taking your vehicle to a repair shop to find out why your Check Engine light has come can be incredibly expensive. The “diagnostic” fee alone can be outrageous. Hundreds of dollars just to be told that there is some minor problem that takes five minutes to fix. 

Do you want to stop paying ridiculous prices just for information? Do you like to tinker with vehicle settings so that it may run better and get better mileage without sacrificing performance? Maybe you’re a mechanic that would like to save time looking up codes and deciphering what they mean? 

OBD2 dongles and software communicate with your vehicle’s computer to tell you what that Check Engine light means and other diagnostic information. In addition, you can also use the software to alter your vehicle by giving it better gas mileage and more horsepower.  To fix a car it’s important to have the right tools for the job. There are several scanners to choose from, here are some of the best programs on the market.

Some low reviewers were frustrated with the additional scanner requirement, although it is a relatively straightforward system. Downloading and setting it up is easy and ready to go in minutes. The PCMScan is one of the simplest options but in some cases, the layout can be unfamiliar for new users.

ProScan is easily one of most user-friendly Windows OBD2 software on the market. It’s biggest strength is consistent stability and development based on  thorough know-how of automotive protocols and sensors. 

One of the best features in ProScan that’s somewhat lacking in others – is timing performance. Or at least one of the most accurate implementations of this feature. Meaning you can conduct live accurate measurements of speed and torque gains after adjusting it’s ECU parameters. 


Some of the most important benefits are the fuel economy tool, the vehicle connection manager, the freeze frame data, the oxygen sensor test, and the diagnostic report generator. 

The fuel economy tool helps adapt the driving behavior to lower the fuel consumption. The analysis is available after a quick drive. The vehicle connection manager is an interface seen when launching the program. It shows the connection status and reports if failure happens. 

Freeze frame data allows monitoring ant data and any period by saving all the previous information. It also shows detected problems and their solutions.

The EOBD (European on-board diagnostics system) is required in all petrol vehicles since 2001 and in all diesel cars since 2004. These systems are more advanced than the original OBD systems, but are much the same as the OBD2.

Users can make a diagnostics of a vehicle using Mac OS and find out the reason for engine indicators without the manufacturer’s pack. The connection is simple, and the user can diagnose and see the results in real-time. Users are able to make a diagnostic of their car using their phone/ipad and discover a multitude of information about their vehicle. From viewing engine and gearbox fault codes and displaying their meaning, to clearing the malfunction indicator light. Users can see car speed, engine speed, engine temperature, spark timing, inlet air quantity, torque and more. Users are able to find this information, record, save and improve.


One review found that EOBD Facile did exactly what is said in the description. When used in conjunction with Total Car Diagnostics ELM327 wifi. It worked fine and detected engine management faults and allowed them to clear the MIL successfully. 

Another review tried EOBD-Facile, but found TOAD PRO a lot more professional and user friendly. 

One user found EOBD very inexpensive and serves its purpose on MacBook air, although it doesn’t function correctly on Dodge vehicles. 


  • Clear check engine light
  • View issue with engine codes
  • Monitor manufacturer error codes
  • Backlog of records of GPS data
  • Make recordings of trips and save 


  • Not as user friendly as other softwares
  • Not as professional as other softwares 
  • Doesn’t work on Dodge vehicles

Final Thoughts

Although it may work for some and serve its purpose as described, most users find other systems better. It is inexpensive compared to other OBDIIs but TOAD might be the safest bet for the best results. 

9. Movi and Movi Pro

Movi/ Movi Pro has the ability to read information from the vehicle’s engine control module (ECM) – without complicated setup on your Mac computer. So you’re after simplicity while still needing absolute reliability on pulling car faults with precise-live PID parameter reports – then this is the ideal OBD app for you. We think it’s easier to grasp and less overwhelming than tProhe above OBD II Auto Doctor.

Their free version is sufficient for most regular car owners. However only the paid version can clear the DTC faults codes.

Software can extract every historical failure (DTC) of a vehicle. It can also clear the ‘check engine light’ off as it extracts problematic trouble codes.


Every failure (DTC) of a vehicle is saved in the engine control module (ECM). Reading this information can help professionals to identify the problem and fix a car. Movi™ car diagnostic software helps to see these trouble codes, extract the car’s freeze-frame information, and clear it so that it can turn your check engine light off.

Reviews of the application are upset that there has been no update in years. They spent good money ($50-$80+) and they are very disappointed. Some say the free Movi software on MAC is super as all they needed was to reset emission on a car to get it ready for inspection. 


  • Read/clear DTCs
  • View/clear freeze frame data
  • View fuel consumption and fuel economy
  • Monitor virtual horsepower and torque
  • Make graph up to 4 engine indicators at the same time
  • Real time data 


  • Hard to use
  • Weird hookup via BlueTooth 
  • Hasn’t updated in years

Final Thoughts 

Movi Pro makes it easy to graph, record, and even listen to your vehicle’s engine data, all in real-time. But users are frustrated with the lack of update and support. Movi Pro hasn’t updated in years and it’s overpriced. Avoid the waste of money. Their free version will suffice for most regular car owners. However, only the paid version can clear the DTC faults codes.
