VXDIAG VCX FD vs. Mongoose Plus GM

Question:

My main focus is for use for programming and advanced diagnostics on the 2021 GMC sierra truck.  VXDIAG VCX FD GM and Mongoose Plus GM3 which to choose?

Here is the basic comparison between VCX FD and Mongoose Plus GM3:

Feature	VXDIAG VCX FD GM	Mongoose-Plus GM3
Vehicle Coverage	Supports multiple brands, including GM, Ford, and Mazda, making it versatile for multi-brand workshops.	Exclusively designed for GM vehicles, ensuring optimized performance and compatibility.
Protocol Support	Incorporates the latest CAN FD protocols, enhancing its ability to communicate with newer vehicle systems.	Supports standard GM protocols; however, it may lack the latest CAN FD support found in newer diagnostic tools.
Software Compatibility	Compatible with various OEM software applications, providing flexibility in diagnostics and programming.	Works seamlessly with GM’s TIS2WEB and Tech2WIN, offering a streamlined experience for GM vehicle diagnostics and reprogramming.
Price Point	Generally more affordable, making it an attractive option for individual users and small workshops.	Priced higher due to its specialized focus and official support, which may be justified by its robust performance and reliability.
User Experience	Some users have reported challenges with software installation and occasional connectivity issues, which may require technical expertise to resolve.	Users appreciate its reliability and ease of use with straightforward installation processes and stable connections, contributing to a positive user experience.

 

In contrast, VXDIAG VCX FD provides broader vehicle coverage and supports newer communication protocols like CAN FD, some users have encountered challenges during software installation and occasional connectivity issues. These hurdles may require additional technical expertise to overcome.

Conclusion
If your primary focus is on GM vehicles and you prioritize a stable, user-friendly experience with official support, the Mongoose-Plus GM3 is a compelling choice. Its dedicated design for GM diagnostics and programming ensures compatibility and reliability.
However, if you require a more versatile tool that can handle multiple vehicle brands and support the latest communication protocols, the VXDIAG VCX FD offers a broader range of applications. Be prepared to invest time in setup and troubleshooting to fully utilize its capabilities.
Ultimately, the decision should be based on your specific diagnostic needs, the range of vehicles you work with, and your comfort level with potential technical setup processes.

How to Use Techline Connect with VXDIAG VCX FD?

VXDIAG VCX NANO GM and VCX SE don’t support CAN FD protocol. To program modules for new GM CAN FD models via Techline Connect, you will need the new VXDIAG VCX FD J2534 passthru.

 

Here vxdiagshop.com will show how to set up VXDIAG VCX FD with Techline Connect SPS2 for online programming.

First we are going to get the ACDelco Techline Connect software. We'll just open up your browser type in ACDelcoTDS, go log in or register. If you don't have an account you can click Don't have an account and sign up.

If already have one, go to log in.  Scroll down accept the terms and conditions. You can get subscriptions for all the different diagnostic tools.

Any one of these will get you into the TDS software. If you didn't already have a subscription you could click here and add one vehicle.

You'll have to add the VIN for the vehicle but in order to do that first you need the software so if you click on this should bring us up to the page where we can get the software here. We are click on this Download Techline Connect and you should see it start downloading up there.

Take a bit, 9 minutes left. Download is done.  We can go into our downloads folder and click on that file and it should install the software.

Just hit yes it'll do its thing. It's done. We can hit Finish and it's automatically starting up Techline Connect application.

But we need to launch it through the the browser so we'll just close out of this and it's important to not have this launch Techline Connect as admin checked for some reason it doesn't work if you have that box check off so we'll just hit this launch Techline Connect button and hopefully it'll open up again.

We'll probably have to restart this a few times see it's installing some software updates. We will just close out of that.  It's a little bit of a painful process. Now if we close this go back to our admin thing same thing go launch Techline Connect you got to hit yes and you'll see it's in installing updates to all of these software packages here and whenever something like this pops up just keep hitting next or yes or or whatever it takes to get it done for.

We're in so this is where you would connect to the vehicle but the problem is we don't have a j2534 tool yet and that is where we’re going to use the VXDIAG VCX FD GM J2534.

So we'll just close out of this for now and we'll go back to our web browser and open up a new tab. Visit www.vxdiagshop.com or vxdiag.net to download VX Manager Beta 1.8.9 for VCX FD. 

Make sure you install the correct vx manager driver for VCX FD. Don’t use regular vx manager for VCX SE/VCX NANO series. 

Then go into your downloads folder and it’s a zip file so you got to right click on it Go extract all and and now you’re inside the folder you can just click on this and it should install the software for you. We will run VX Manager 1.8.9 Beta.

Just hit finish and the software will fire up.

Then connect VCX FD adapter with laptop.

It will show up device. Update firmware and license.

Then go to Diagnostic tab to update Passthru driver. Install passthru driver only. Don’t need to install GDS2 driver in vx manager. There is “+” icon means the Passthru driver requires update. If does not have “+” icon, ignore it.

We can close this and go back to our browser. Plug the vcx FD into the vehicle. We’ve got the VCX FD plugged into both the laptop and the OBD2 port in the vehicle.

Let’s back into vehicle programming software, hit View and Add VIN, launch Techline Connect.

It is loading the SPS Program, we can go select vehicle. Then select the VXDIAG J2534 device. Hit continue.

Now you go into this SPS2 tab over here. Click on that and this is where you can program all your modules.

It's already got the VIN of your vehicle. You could manually enter a VIN or you can detect a new vehicle.

We'll go Next. This is where it finds all the controllers on the vehicle. You can scroll down and see all the different modules. Select the module you need to program. 

There are many programming examples on our blog.
