VXDIAG VCX NANO Toyota & Godiag J2534 Which is Better

Vxdiag vcx nano Toyota and Godiag gd101 j2534 which is a better diagnostic cable for Toyota & Lexus?

Both are compatible with Techstream software.

VXDIAG VCX NANO emulates Techstream like OEM VCI, godiag J2534 just works as j2534 passthru.

According to users' report, godiag j2534 is not fully compatible with techstream, even after using their drivers.

1).

Beware, Avast and then multiple other antiviruses on virustotal marked the driver program and the Techstream software available for download from their website as having trojans. It will read codes, but don't expect to be able to change vehicle configurations with it (tried on two lexus, neither worked – bought a VXDiag vcx nano toyota cable after buying this and it worked flawlessly – but is much more expensive). Godiag wouldn't recognize my LS400 (would read as LS430) nor RX350 (had to manually do it) when plugging in, VXDiag got both of them right on first try.

2).

I purchased godiag cable because it looked better than the cheap clear J2534 cables you see online, primarily wanted for Toyota techstream to be able to clear codes and do some customize features on my vehicles.
Note that this WILL communicate with your vehicle however it can basically only "see" things.
It cannot and will not perform any setting changes, cannot communicate with a vast # of computers etc and you cannot do any programming with it.
If you need something just to see codes than this will work fine but it is not the universal tool for performing any functions.

3). With vxdiag vcx nano you can perform online programming with Toyota online subscription, however, godiag j2534 cable does not work with an online subscription, only works with offline techstream.

So godiag j2534 is just for starters, for professional use, better go with vxdiag.

GM E38 SPS Programming with VXDIAG VCX NANO

Here is the new GM E67 and E38 SPS programming review from one of vxdiagshop.com's customers.

Just used the new Techline, $45 subscription, and a VXDIAG VCX Nano gm interface to flash my $27 EBay E67 from 2006 Malibu to a 2012 ZL1, simply using Manual VIN, on the bench. No other modules installed.

Then, connected it to the real 2010 Camaro E38, another $45, updated it's OS, and flash updated the ABS module, since I often see "Service Stablitrack" on startup. That was one of the updates the newer ABS OS fixed.

I have the vx manager software installed and running with the gm and pass through options included.
I have also installed gdi and tech2 software.

I can get tech2 emulated software to run but I get a warning not to use sps – although from what you say, it should work.

If you want to use the nano with sps, you need to uninstall everything except the passthru driver for the nano. Then go to acdelcotds.com and choose sps programming, install techline connect and eventually if you get it all installed and updated you can use the nano for sps. It does work but can be a struggle to get sorted. Need windows 10, 4gb ram will work.

The VCX software itself (VCX Manager) is fine, installs no problems, at least for me. The problem comes when you try to install the Tech2Win and MDI software. But you dont need that part to run TechLine. TechLine connects to the VCX Directly.

I did make one mistake on that Ebay E67… because it was a much earlier ECU than what I told TechLine, I needed to use REPLACE, and I used Manual flash, which ended up corrupting the VIN since it was not from, which is not a show stopper, but once Techline flashes the ECU, it will not re-download the files to re-flash, as it thinks it's already flashed so it skips it on repeated attempts. So I need to use other tools to fix the VIN, which I do not have, but the VCX Nano itself works just fine,

Flashed my 2010 Camaro BCM to the updated OS, and also flashed the stock 2010 E38 in the same camaro to the newer OS, using Techline, both had no problems.

No problems with any of it, worked great.

Mini VCI or VXDIAG VCX NANO for Toyota VGRS System?

Mini VCI or VXDIAG VCX NANO Toyota which is a better cable to connect Toyota/Lexus VGRS* system?

Here is the customer review.

I have a Lexus 2004 gx470. It has the VGRS steering warning on the dashboard. It previously had another warning related to the VSC and my service told to clear that fault by doing a wheel alignment and resetting/clearing some codes with techstream software.

I have been reading through the threads on the VGRS issues and had downloaded Techstream to do a steering angle adjust.

I purchased the mini vci cable off of Amazon and am running version 1.4.8 and techstream 16.000.07. In the yellow settings I'm not getting a VGRS option, There is no vgrs tab for me to open is the problem, I have the abs/vac/trac and that's it. I'm trying to recenter the steering wheel. Have read on the forum where the steering angle adjustment is in the vgrs tab.

Do i need a new version on this? So I was able to upgrade my techstream to version 18, still not able to access the VGRS system on the vehicle. I've read where it can be related to the cable. Not sure on that end.

Then i get the vxdiag vcx nano toyota cable and download techstream v18 on vxdiagshop.com site. I see there is a VGRS section, then click on utility on the left to get adjustment menu.

I thought it was a cable issue.

VGRS*

VGRS= (Variable Gear Ratio Steering) System
VGRS which variably controls the steering angle in accordance with the driving speed, has been adopted as optional equipment on the model for Europe.
This system is controlled by the VGRS ECU, which operates the VGRS actuator that is mounted on the steering intermediate shaft. The operating angle of the actuator is thus added to the steering angle of the intermediate shaft in order to vary the turning angle of the front wheels in accordance with the vehicle speed.
The VGRS ECU is equipped with a diagnosis function and a fail-safe function.

VXDIAG VCX NANO GM Cadillac SRX 2007 Review

VXDIAG VCX NANO GM review on May 30th, 2023.

"I used the VCX Nano to reprogram a Body Control Module (BCM) in my daughter's 2007 Cadillac SRX. It took me a day to figure out how to get it setup and working with the emulators. There is a specific order to install the apps so read the directions that come with the USB stick. Not as difficult to use as some reviews indicate. It will help operation if you know a few things about computers.

Works perfectly for programming. Once I had it setup I downloaded my SPS programming from ACDelcoTDS website and I was able to connect the VCX Nano to the vehicle to program the VIN on the BCM, to set regions, program other modules, and to read and clear codes. This saved me a tow truck ride to the dealership and a couple grand the first time I used it. Well worth the money."
