Blacktec 420 is an interesting code reader that seems to be different from others mostly because of Bluetooth connection and their own diagnostic app. Unfortunately, the app was not available in my location so I couldn’t test it out.

Blacktec 420 vs other code readers
I included Blacktec 420 in my best engine code readers overview. I can recommend it to anyone who wants to either keep an eye on the engine’s health or diagnose and fix engine issues.
What can you do with Blacktec 420?
As mentioned in the beginning, this Blacktec reader is capable of everything that a good code reader should have. That is support of 10 global OBD modes. These modes are basic functions in OBD2 and a good scanner should be able to use all of them, even when it costs less than the price of one diagnostic scan at the car shop.
Read Fault Codes: Identify issues or determine which engine system has a fault. Use the OBD fault codes database for details.
Clear Fault Codes: Turn off the check engine light by erasing fault codes. Document necessary data before clearing.
Read Freeze Frame Data: Access data recorded during faults to understand issue conditions, aiding both DIY and professional repairs.
View Live Data: Monitor engine health in real-time with live data graphs, crucial for diagnosing problems.
Check Readiness Monitors: Verify the health of emission-related components. Display the status of all monitors.
Display Vehicle Information: Retrieve ECU IDs and VIN numbers, useful for checking used vehicles.
