7 Best OBD2 Software in 2017 and Beyond: Reviewed and Tested

Purpose of this article is to save you time researching reliable professional OBD software for your PC/laptop.

Basically we’ve done all the research for you (having used and tested them all extensively) – and will present our 7 top researched OBD2 diagnostic software.

Basically last judgement is on you. See their website, get a feel for it. And get one that makes sense to your unique automotive needs. For this reason, we’ve kept our reviews bullet point short.

There’s not much to say, as they’re all basically going to do the SAME thing end of the day, else we would’ve not mentioned them here.

What we can tell you about them all is:

  • These are not free OBD software. For free OBD2 software (for ELM327 scan tool), download EasyOBD. It’s the best “free” you’ll find anywhere.
  • Automotive industry generally only targets Windows. There’s only two (decent) OBD2 software for MAC in list below.
  • All software support ELM327 OBD2 Bluetooth, WIFI and USB interface. You can find ELM327 install instructions here.
  • None of these software are bidirectional. For bidirectional, you’ll need high-end OEM scan tool (which are usually in $1000+ range).

So let’s begin with brief intro guide about scanners / code readers / diagnostic tools…

Automotive engineering has come a long way since Karl Benz developed the first petrol or gasoline power automobile in 1885. What started off a form of transportation to solely move people from point A to point B has not turn into a luxurious, fast option to transport people from A to B.

Before the technological boom, cars were plain and simple and easy to fix. However, as we have advanced in all aspects, cars now are equipped with the most technological items that one can think of, from air conditioner, to navigation, to even autopilot.

With the technological advancement, automobiles are becoming increasingly smarter. Today’s cars can collect information navigating the best route available, to adjusting the fluids in the car to fit the driving condition, to lastly, detecting errors in the engine.

Most automobiles you on the road today all have an on-board diagnostics, or an OBD2 port which provides access to all the data from the engine control unit (ECU). With the data, a technician can determine the car’s problems and see if maintenance is required.

obd-port-softwareStep 1: Connect ELM327 to your car’s OBD port.
Step 2: Install ELM327 drivers.
Step 3: Launch OBD2 software, and click “Connect”. It’s that easy!

To access the information from the ECU, you would need a computer and software to plug the port and gain access. Because of this trend, more and more companies are now developing and creating software which can cater to the end-users and assist them in accessing the ECU for data.

Usually, the product will come with two pieces of equipment, a device, hardware or cord and the software. The hardware/cord connects the ECU to the computer. The software then reads the data and analyze the data for the end-users. The main goal of this application is to assist with the maintenance of the vehicle as well as prolonging the life of the vehicle.

Below, we have gathered seven different types of diagnostic software from seven different companies which we believe are the best software that you can purchase now for your Windows/Mac laptop/PC computer.

  1. Decided on choice 1 software in the list. Arrived fast and in excellent condition. Worked on my first try on a 2008 Honda Accord V6. Scanned and got code (P1457). Reviewed code in software, erased code. Result? stagnate, “check engine light” (CIL) vanished! Easy. Saved me time, a trip to the shop, and an expensive diagnosis fee at mechanic shop.

  2. Tried EOBD Facile. VERY inexpensive OBD II software. Serves its purpose well on MacBook air. This is my second try at testing obd software, know they’re not all created equal. Be advised this works on most cars but not all. It serves my purposes but I don’t use it on Dodge. It doesn’t function correctly on them (then again most scantools have issues with them). Works on 2 Jeeps and a Mercedes, so reading fault codes and or resetting them is a breeze. I DO have a way more expensive handheld that works on all vehicles but this is my go to option due to large screen real estate you have on laptop vs handheld. Quick to read, isolates a problem system so allows you to check micro switches etc – to narrow down where to look and why. Saves throwing money at something before confirming an issue. Worth the few $$$ for most people’s workshop. Hope this review helps make an informed choice on which scanner you need. For most DIYers this will suffice.

  3. OBD2 ELM327 with ProScan Windows viewed faults and diagnostics successfully detected P0220 and P0229, which caused me to fix the Throttle situations myself. Auto shop charges $40 to plug in the analyzer, so I’m ahead on this.

  4. Tried TOAD and it’s a great Windows software, that’s clearly putting mobile apps to shame! I used TOAD lite version (bought on eBay but no longer available there) for years before finally getting the Advanced version on the website. The paid “PRO” version is definitely worth the money. I have toad-scan paired with a cheap ELM 327 adapter (about $15 on eBay) and it works great on my Surface PRO 3. I have not come across any vehicle that TOAD can’t communicate with. It has saved me money on repairs on my truck and car as well as made money by diagnosing problems with other peoples vehicles. Would purchase again, even for twice the cost.

  5. Have bought Movi OBD app and using on Macbook pro 13. So I took the ZS 2.0 TD out for a blast to test the software. Bearing in mind it’s the 118 with decat, SDI injectors, boost increase (physical boost gauge showing 23Psi). Why was my maximum Bhp 93.4, and my max torque 177 and boost only showing 17.8?? Am I doing something wrong? Is it the ELM327 reader or the Movi obd2 app? And the car is fine btw. It pulls exactly like you would expect a car that’s producing around 134-145bhp with all the mods. Oh, and regarding the max bhp, I took the car right up to the redline with foot nailed to the floor in 1st, 2nd, 3rd and still the app showed a max of 93.4??

  6. I bought ProScan and ELM327 bluetooth from totalcardiagnostics on eBay with a little skepticism, reading everything about bad clones really put me off. This product is the real deal, no delay, works every time. Tested on Windows 10. I believe this is the cheapest, most reliable product for reading OBDII diagnostics over Bluetooth. I know of Android options, but laptops just give more real estate, so can see 4-5 graphs simultaneously. You can’t do this on Android phone or tablet.

  7. Read this article. Already former buyer of TOAD-Lite back in 2011. Their proscan software is still excellent, holding up to modern auto industry changes. Didn’t know about pro ver though. May upgrade later, but happy camper since 2011.
