FOXWELL NT634 vs. NT624E vs. NT624 Elite: Detailed comparison

Key things in common

The FOXWELL NT634, NT624E, and NT624 Elite are nearly identical in their exterior design. All three use a durable, rubberized housing that’s easy to grip and built to last. Additionally, they have similar navigation button interfaces, including general controls and hotkeys for quick access to your most-used functions.

In terms of functionality, each FOXWELL scan tool’s core is a full OBD2 diagnosis. Thanks to that, you’ll get access to all 10 modes of OBD2 with any of these diagnostic tools, including smog, EVAP system tests, reading/clearing codes, and viewing live or freeze frame data. 

FOXWELL NT624 Elite offers special functions like EPB and oil reset

Key differences

Design and specifications

From a design standpoint, the differences between these tools are limited. The NT634, NT624E, and NT624 Elite OBD2 scan tool are roughly the same size and shape, and the menu layout of all 3 products is similar.

The FOXWELL NT624 Elite is the fastest OBDII scan tool of the three when it comes to the software specifications. Of interest to international users will be its broad language support, with 13 options including less-common languages like Hungarian and Thai. 

Overall features and functions

In addition to OBD2 diagnosis, the FOXWELL NT634 can also read codes and live data from the transmission, ABS, and SRS systems. Its built-in data manager produces a diagnostic report based on all these readings, which can be easily downloaded and printed through a PC.

Both the NT624E and NT624 Elite expand on this to offer an all-system diagnosis. Because of that, they can identify issues in the HVAC system, tires, and other electronic systems other OBDII scanners can’t diagnose. 

The FOXWELL NT624E OBD2 scan tool doesn’t just read codes, either. It graphs data from a range of electronic modules and can even merge PID graphs. You’ll get a full, comprehensive picture of what’s going on in your engine. 

Similarly, the NT624 Elite has robust data reading and graphing capabilities. This OBDII scanner is even more potent than the NT624E, showing information from drive systems and auto body parts like the chassis, door locks, and windows. Like the FOXWELL NT634, all of this data can be recorded, played back, and printed. 

Extra features/functions

For the price, the reset and service functions of the FOXWELL NT634 are especially impressive. It’s far more than an OBD2 code reader, with 11 service functions, including advanced features, like gear learning and injector coding. 

Comparatively, the extra features of the FOXWELL NT624E are more limited. This OBD2 diagnostic tool includes oil reset and electronic parking brake (EPB) service, including EPB calibration and adaptation for many vehicle models. 

Finally, you’ll also get both oil reset and EPB reset from the FOXWELL NT624 Elite. This functionality is equally comprehensive, including bleeding the brake fluid and reset of the system after replacing the discs or pads. That’s incredibly helpful for those making at-home repairs. With this OBD2 scan tool, you can change your oil or maintain your brakes without the need to waste money on a mechanic. 

Supported protocols

The FOXWELL NT634 supports all 5 OBD2 protocols used on modern engines. Additionally, it supports EOBD protocols for vehicles made and sold in Europe. This is also true of NT624 Elite. 

On the other hand, the FOXWELL NT624E only supports OBD2 protocols, though it does have broad support within that category. 

Supported vehicle makes

Any of these OBDII diagnostic scanners will function as an FOXWELL code reader for any OBD2-compliant vehicle. Unfortunately, their compatibility isn’t as comprehensive for non-OBD2 functions and systems, though they offer relatively broad support. 

The NT634 supports 4-system diagnosis for 63 manufacturers, up to and including 2019 models. Each of its 11 service functions has a specific range of supported vehicle makes, so you’ll want to verify what’s supported for your vehicle by e-mailing [email protected] with your vehicle’s information. 

All-system diagnostics are available for 58 manufacturers with the FOXWELL NT624E. However, it only supports oil reset for 49 manufacturers and EPB service for 42. 

The FOXWELL NT624 Elite supports the fewest manufacturers, though by a very narrow margin, with all-system diagnostics for 56 manufacturers. Its EBP service and oil reset support is similar to that of the FOXWELL NT624E.

Software and updates

Updates are free for life with all 3 of these OBDII code readers. For the FOXWELL NT634, start by registering your device on FOXWELL’s website. You can also download FoxAssist, an app that helps install updates. Keep in mind updates are only available through Windows PCs and aren’t supported for Apple devices. 

You’ll need to update FOXWELL NT624E and NT624 Elite through FoxAssist. Like the FOXWELL NT634, they require a Windows-based PC for updates.
