Group 1: Best Live Data OBD2 Scanner (Under $100)
#1. Ancel AD410: Cheapest scan tool with graph live data
Pros
- Cheap
- Powerful live data function
Cons
- No major cons
Live data function:
In the affordable range of under $50, the Ancel AD410 stands out as a scanner that offers the best graph live data.
With this excellent scanner, you can view real-time data straight from your vehicle’s sensors: intake air temperature, manifold air pressure, coolant temperature, O2 sensors, RPMs, and more.
One of my favorite features is the ability to graph the O2 sensor voltage. I actually managed to diagnose a faulty catalytic converter using this function.
Moreover, the live data loads up pretty quickly too, which is seriously impressive.
However, what truly sets the Ancel AD410 apart is the ability to select and view any 3 parameters in graph live data.
This feature is incredibly useful when you need to compare multiple data points and identify issues faster.
Other special functions:
1. Reading engine codes accurately
Ancel AD410 provides you with quick and concise information about the engine codes, and clearing them is just as effortless.
The menu layout on the screen is intuitive and straightforward, so you will have no trouble navigating and performing the necessary tasks.
2. Convenient smog check hotkey
One of the standout features is the dedicated I/M readiness check button, which is extremely convenient.
With a simple press of the I/M button, you can instantly check if your car is ready to pass the state’s emission requirements. It makes the smog check process a lot faster and hassle-free.
Key takeaway:
The Ancel AD410 is an excellent live data scan tool, offering convenience and peace of mind at an affordable price.
While it doesn’t have advanced features like ABS or battery check, it serves its purpose well and helps you avoid unnecessary expenses at the mechanic shops.

#2. Foxwell NT301: Best OBD2 data logger
Pros
- Can record live data for later review
- Easy to use
Cons
- Show only 1 parameter at a time on graph
Live data function:
If you need a scanner that offers graphing capabilities for live data, look no further than the Foxwell NT301.
This amazing tool allows me to view live data in two different formats:
- graph,
- and digit (chart).
One feature that truly impressed me is the data logging function.
With this handy feature, you can easily record PIDs (Parameter IDs) and playback the data later for review and analysis.
The screen size of the Foxwell NT301 is large, ensuring that you can effortlessly read live data in either graph or chart format.
However, it’s worth noting that the graphing live data feature can only display one parameter at a time. If you’re looking to view 3 parameters simultaneously in a graphing format, I recommend considering the Ancel AD410 instead.
Other special functions:
1. Smog Check
With the Foxwell NT301, you can quickly determine if your car is ready for a smog test.
The I/M button placed in the middle of the keyboard makes checking I/M readiness faster than ever before.
2. Code reading & clearing
When it comes to those frustrating check engine lights, the Foxwell NT301 proves to be highly reliable.
It accurately reads the codes, allowing you to pinpoint the reasons behind the warning lights. Once you’ve fixed the problem, clearing the code is a breeze.
I have full confidence that this function will save you significant diagnostic fees from repair shops!
Key takeaway:
The Foxwell NT301 is an affordable scanner that offers live data capabilities. However, it’s important to note that it can only display 1 parameter at a time for live data.
If you’re a fan of the Foxwell brand, then this scanner is definitely a great option to consider. It provides reliable functionality and is well-suited for various diagnostic tasks.

#3. INNOVA 3040RS: Perfect choice for ABS live data
Pros
- Can read & reset ABS codes
- Repair suggestions for FREE
- Hotkey for live data function
Cons
- Show only 2 parameters at a time on the graph
Live data function:
The Innova 3040RS is specifically designed to make accessing live data functions quicker and more efficient.
It features a convenient hotkey “LD” (live data). This hotkey lets you quickly find and diagnose problems without wasting time scrolling through menus.
When it comes to viewing live data, you have the option to see it as numbers or as a graph.
The custom view feature is a real plus, allowing you to select and monitor specific sensor readings that you’re interested in.
However, please note that the scanner can display only two graphs at a time.
Other special functions:
1. ABS codes reading
When diagnosing and resetting engine codes and ABS codes, the Innova 30340RS performs admirably.
It delivers highly accurate results, which is essential for effective troubleshooting.
It would have been even better if it could also read SRS codes, but unfortunately, that feature is not available.
2. RS2 app for FREE predicted repairs
Another standout feature is the RepairSolutions app, which can be paired with your mobile phone.
This free app offers valuable information, such as:
- show your car’s issues and likely parts that will need to be replaced.
- suggest scheduled maintenance.
The combination of the scanner and the app elevates the Innova 30340RS beyond your typical code reader, making it an even more valuable tool.
Key Takeaway:
The Innova 3040RS is an excellent choice for those seeking a scanner that offers both live data functionality and the ability to read ABS codes.
As a bonus, it’s proudly made in the US, ensuring quality and reliability.

Group 2: Best Live Data OBD2 Scanner ($100 – $250)
#1. BlueDriver: Best Bluetooth OBD2 scanner with live data
Pros
- Full-system diagnostics
- Repair suggestions
- Oil/TPMS reset
Cons
- Can’t work with third-party apps
- Can’t change the size of the gauges
Live data function:
When it comes to live data, my top choice is definitely the BlueDriver. What sets it apart is the ability to display live data in three different forms:
- gauge,
- chart,
- and graph.
It’s worth noting that the size of the gauges and numbers cannot be adjusted, but that doesn’t take away from the overall functionality and usefulness of the BlueDriver.
Regarding graph live data, the maximum number of items you should monitor simultaneously is 5.
If you select more than five PIDs, BlueDriver will warn about potential excessive lag.
During my testing, I did notice a slight lag when graphing 4 to 5 PIDs. However, it was minimal and didn’t significantly impact my overall experience.
Other special functions:
1. Full-system diagnostics
BlueDriver is a fantastic scanner that can read trouble codes from a wide range of systems in your vehicle. However, the specific systems BlueDriver can scan may vary depending on your car model.
While some cars can enjoy full system scanning, others may be limited to the four main systems: ABS, SRS, Transmission, and Engine.
2. Repair report functions
You can rely on this function when you don’t know where to start after reading codes. Repair report will tell you:
- Estimated cost
- Fixing suggestions on how to repair based on the experience of hundred US technicians.
- Suggested parts to replace with links to purchase
It’s like you have a mechanic tutor by your side and ask him whenever your car has problems.
Key takeaway:
The BlueDriver is a truly versatile tool that can handle everything, from OBD2 real time monitoring to full-system diagnostics and even oil reset.
I highly recommend it to anyone working with cars and light trucks!

OBDLink MX+ let you get the add-on for specific car brands like Toyota, Ford for FREE. Therefore, you can scan and pull the trouble codes from all systems.

#3. Launch CRP123X: Affordable live data scanner with large screen
Pros

- Large screen
- Can read ABS, SRS, and Transmission codes
Cons
- Short cable
Live data function:
The LAUNCH CRP123X stands out from basic scanners like the Foxwell NT301 and Ancel AD410. Its large touchscreen takes the live data functionality to the next level.
You can tap the screen to select specific data lines, saving you time compared to scrolling. The screen is also large, providing clear horizontal graph live data.

Launch CRP123X will do much more than just check and clear engine codes. It can diagnose the ABS, SRS, and transmission systems.

It saved me a lot of time and guesswork in pinpointing the problem.
