2019 GM MDI2 vs GM MDI diagnostic programming tool

2019 GM MDI2 shares the same functions and vehicle coverage as GM MDIGM MDI2 features in a light blue color shell and brand-new shape, GM MDI features in dark blue shell.

2019 GM MDI2 is optional with Wifi version and USB version (means wired network connection is not allowed)
GM MDI is only optional with Wifi version.

Similarities:
1. Both GM MDI2 and MDI are compatible with GDS2 Tech2Win

gm-mdi2-vs-gm-mdi-03
OS: WIN7 64bit
Computer: the year after 2008, 4GB RAM
Pros: gds2 software needs no activation
The method to use: Insert the HDD with GM MDI gds2 software into your computer; the software can be used directly with the GM MDI scanner.

Tech2win is the program that works just like a Tech II, but the program running on a laptop for the MDI (clone MDI device which the Nano is).
GDS2 is the program for the C7, like the tech II and tech2win with midi is for the C6 instead.
On the VM GDS 2, you don’t need an account with GM to use it, short of needing to do SPS programming, which you will need a TDS SPS subscription instead ($40 for 2 years per car).

So the low down for most laptops,
Wants to be running in win 10 for TDS SPS programming.
Needs to be running a multi-core chip in win 7 or above to run VM player for VM GDS2.
Need to be running in Win 7 native (32 or 64 bit) to run Tech2win (will not work in a VM shell).

2. Both GM MDI2 and MDI have the same capabilities
Full dealer level diagnostics and programming for all Vauxhall /Opel 16 pin vehicles from 1996 to 2017.

1). Clone GM MDI Review
Compatibility:
Device works with GDS2 (Opel)
Device works with Tech2Win (Opel, Hammer)
The device does not work with SAAB via Tech2Win

GM MDI is working in Consult 3 plus
gm-mdi2-vs-gm-mdi-06

Cars tested- success & failure list:
1: SAAB 9-5, 2003, 3.0 TID- works
mine is a clone from China.
MDI Software 8.1.135.13
GT32
SAAB NAO V9.250
Simply pressed OK when Candy detected and all worked.
Tested on SAAB 9-5, 2003, 3.0 TID

2: 2014 model – works
SAAB NAO V9.250 is from 2014. Already tested.
The 2003 year too old – not interesting for me.

3: Saab 9-5, 2003, 3.0 – works
Tested by my own, works with Saab 9-5, 2003, 3.0

Online or offline issues:
1: online – good, offline – bad
GM MDI good, interface works online.
update mdi 100%.
offline too bad for new cars.

2: wifi card compatible
at now, Chinese clone GM MDI with the squ wifi card

3: wifi not working but works well with USB
I bought a cheap one and it only worked with USB. The wired network and wifi did not work. In fact, the card flash socket was missing from the board. Build quality was not to bad. I just use it to flash newer PCM/ecm’s.

Quoted: a man of his words to trust in:
I would not go by pictures posted on the web as vendors share the same photos but the MDI had a different ethernet connector and missing card flash socket. It was advertised as (without wifi). It does work fine on USB and for flashing PCM/ECM because at 480 Mbit/s it is almost 5 times faster than ethernet.

The MDI clone works fine with tech2win and also TIS2000. Used it for diags and PCM flashing with no problem (through USB port only)

2). Tech 2 Scan Tool TIS2000 VS VXDIAG Nano VS MDI in the installation
ON the VX nano, sometimes you can get Tech2win to run on win 10 (maybe if you have an AMD chip or not, but have not figured that one out yet), while on my i7 machine, Tech 2 win will not run in win 10 instead.
Tech2win is the program that works just like a Tech II, but the program running on a laptop for the MDI (clone MDI device which the Nano is).
GDS2 is the program for the C7, like the tech II and tech2win with midi is for the C6 instead.
On the VM GDS 2, you don’t need an account with GM to use it, short of needing to do SPS programming, which you will need a TDS SPS subscription instead ($40 for 2 years per car).

So the low down for most laptops,
Wants to be running in win 10 for TDS SPS programming.
Needs to be running a multi-core chip in win 7 or above to run VM player for VM GDS2.
Need to be running in Win 7 native (32 or 64 bit) to run Tech2win (will not work in a VM shell).
Tis2000 needs to run in WinXP or built the VM XP shell, so it can be native in XP or in a VM shell so long as you have a multicore processor.

So the way I do it, since Tech2win will not run native on my machine with an I7 process in win 10, I have a dual boot up in win 7 and win 10 both.

Win 10 is used to run pretty much everything I run, short of Tech2 win, which I use the win 7 64 boot up to run it.

So in the Win 7 dual boot up (small 40 gig partition off the drive), have tech2win to use the Nano as a Tech II, plus VM GMSI, and Tis2000 in a VM shell since I may need them as well for the VX nano running as a tech II when running in win 7.

In win 10 boot up,
VM GDS2 V17
TDS using internet explorer native with account
VM Tis2000 built on a full XP OS with account
VM GMSI

If you want to just run a single OS system, instead of a dual boot up machine since you can’t get Tech2 win to run in win10, then you can run pretty much run everything in win 7 (32 or 64 bit), so long as you have a CPU that has multicores. Hence you going to need to run at least VM player for the VM shells, and it takes as a multi-core processor to run VM player (or VM workstation).
Note, I have VM workstation, instead of just VM player, since I build other VM shells to run in windows as well.

So again, it really just depends on your machine, and if you Tech2win will run correctly on it or not.
Hence the problem is when you open Tech2win, you need to get three pop up screens once Tech2win start the program.

The first screen will ask you what country, and you select North America.
gm-mdi2-vs-gm-mdi-07

The second pop up will ask you if the device is an MDI 1 or MDI 2, and you select MDI 1.
gm-mdi2-vs-gm-mdi-08

The third pop up screen will ask you if you want to select the USB device (the nano plugged into a USB port), you select it, then it will take you to the Tech2win start screen.
gm-mdi2-vs-gm-mdi-09

So if you open Tech2win, and you don’t get the three pop up screens but just goes directly to tech2win main start screen below instead, then Tech2win is not going to work on your machines win 10. Hence the problem is a glitch in midi and tech2 win interface to select the nano, to begin with (what the pop-up screens are), and if you can’t select the nano via the pop-up screens, tech2win will not connect to the nano in the first place.
gm-mdi2-vs-gm-mdi-010

Again don’t know if this is an AMD verse Intel CPU problem in win 10, but the only laptops that I have seen run Tech2win in windows 10, just happened to be laptops running an AMD CPU instead. And yes, have tried to skin the cat many way with added drivers and compatibility modes, and it’s driver/code line that Win 10 does not have for the Intel CPU (but seems to to have for the AMD CPU that is a carry over from the win 7 days to make the AMD chip work with win 10 instead).

Please enjoy.

SPS Programming Abrites AVDI or GM MDI

Just information for you to make a wise purchase of GM scan tools for SPS programming: (here, I focus on SPS GDS2 on Abrites j2534 and GM MDI)

In the past ( few years ago when I bought my AVDI )

When I bought my tool I used Global Tis v32 and was able to do SPS Programming in my Y20DTH that I have at my desk for tests. All went OK.

After a while during a year of AMS I received the new drivers but because I didn’t like how the AVDI is working and because I make some money using it I dece to upgrade to genuine OEM tool for the brands that AVDI can work.

After a while I bought a genuine MDI.

And after years I did the tests because my friend who has a issue doing SPS Programming. And he asked me to check if its ok at me. And using same ecu that I did SPS Programming alright in the past then now was blocked. So I did and had the same issues as him.

He because has the AMS he received the new drivers after he talked with Abrites company.
For me AVDI its did it job long time ago and I don’t need to buy a new AMS. So I am using when I do what “she” can do.

My friend asked Abrites to fix this issue and they sent to him new drivers versions and then he could do a SPS Programming as well.

But take care this is not working in any ecu.

So my advise for you is to buy a good GM MDI but not VXDIAG VCX NANO and you will be fine.

In my opinion for GM cars and if you wanna do SPS Programming and diagnostics using Tech2win and GDS2 the better is a GM MDI – a genuine or good clone one, or a cheaper cable like a genuine or good clone Mongoose GM Pro2

Or a J2534 tool that its approved by GM.

Maybe for diagnostic FVDI ABRITES Commander is still good but for programming it will not for sure. But if you wish it you can use it and when you will block first ecu you will remember my opinion.

AVDI I hadn’t used anymore for diagnostic so I cannot tell you if its ok to use it in newer car with GDS2. Actually I have no new drivers for a long.

Tech 2 programs Hummer H2 above 2007

Tech 2 Scan Tool on Hummer H2 above 2007… Possible to do programming? what to do in that case?

Hummer-H2-2007

Yes! Actually it does the programming just fine on newer than 2007 GM vehicles!
You must:
Pay for an ACDelco TDS subscription for vehicles above 2007 and you would use the CANDI module that comes with many of the Tech2’s for working with CAN bus vehicles. You can subscribe for as little as two days for $55.

https://www.acdelcotds.com/acdelco/action/subscribehome

This is ONLY needed if you want to program or update the software in a module.

ALL of the build in diagnostics and testing for vehicles up to 2013 works without the subscription or the older TIS2000 software. You only need those for doing actual programming. The older TIS2000 software – that is what has the programming was discontinued in 2007. TIS2000 does have the actual programming for all vehicles up to 2007. After 2007 GM went to the TDS system.

You can also:(for diagnostics and programming)

Get a newer style GM MDI or MDI 2 for diagnostics and programming. The catch with those. They have NO screen or built in software and you must pay for a subscription from from ACDelco TDS to use an MDI.

Other brand units, a very select few can do actual programming and use the pass-through method. NONE have the diagnostics that the actual Tech2 or MDI (with the subscription) will have. Check with Autel and see if they have the full diagnostics and re-calibration for the rear air suspension on a Hummer H2. Not going to happen, there is too little demand for them to hack and reverse engineer that particular bit of code in a Tech2 to figure out the diagnostics and then write programming for that for their tool.

For programming, you also need to have TIS2000 running on a computer or pay GM for a 24 month subscription for their TIS2WEB (Vehicle Programming) for $40 https://www.acdelcotds.com/acdelco/action/subscribehome
The computer will need a serial port for downloading the programming to the Tech2 for programming your vehicle.

How to do programming wit Tech 2:

The way programming works is you connect the Tech2 to the vehicle and tell it you want to program a module.
It interrogates all of the modules on the vehicle for the current versions and the VIN number.
You then connect it to the computer running TIS2000, GlobalTIS or TIS2WEB subscription and select programming in the computer.
It reads the Tech2 for the vehicle info and then presents you with a list of software for all of the modules and shows you which have updated software.

Recommend:

You’d better only do one module at a time which is a good bit more back and forth but safer.
The computer then loads the update to the Tech2. You take that back to the vehicle and connect it and it then programs the module.
The best, most reliable and safest method:
To use a long enough serial cable (its uses 9 pin serial adapters with an ethernet cable to make the cable longer – so you can just use a longer network cable) and do pass-through programming. In that method the process is the same but you leave the Tech2 connected to both the computer and the vehicle at the same time. Once you select programming on the Tech2 then go to the computer and you can immediately update each module right from the computer.

There is a slightly more updated version of standalone TIS2000 floating around on the web which has additional updates that has software updates for vehicles through 2009 as well. I know just using that TIS2000 both GMC truck and 2003 H2 both had a bunch of software updates available to be programmed all of which fix small issues or improve certain aspects.

One example in on the older single compressor air ride like 2003. Those would run and make small adjustments a LOT more often than needed and the software update fixed that.

On the H2 the rear air ride is also one to be very careful of for doing software updates though. For example, 2003 came with the earlier style single compressor but if it were to fail a dealership would replace it with the newer style dual pump compressor. Programming would still think its the original style and would attempt to program it and that would actually cause it to fail. TIS2000, (Global, Web, etc) will warn you about this sort of thing though so just heed all warnings and follow instructions and its fine.

The programming aspect is not needed or required to use the Tech2. The OBD2 Scanner Tech2 still gives you a TON of diagnostics and tests that NO other OBD device has including things like the air ride module, detailed BCM functions, basically you can control and test every computer module in the vehicle.

MDI 2 – The Next Generation, Global Diagnostic Interface Tool

GM-MDI2-1

The GM MDI 2 is the next generation Global Diagnostic Interface tool for both current and future vehicles. It’s a compact communication module with increased processing power and security that manages the transfer of data between a vehicle’s onboard ECU network with an auxiliary CAN bus.
The GM MDI 2 replaces the MDI introduced in 2007 and offers faster programming speed than the GM MDI. The MDI 2 can be used to perform Pass-Thru programming on all GM vehicles built since 1996 and into the future.
Servicing the current generation vehicles will require the diagnostic software, GDS2, Global Diagnostic System 2 running on a local PC device while the MDI or MDI 2 is connected to the vehicle.
The MDI 2 connects to the vehicle via the OBD II connector using a new DLC cable. Connection between the MDI 2 and the PC can be accomplished via standalone (USB) or through a NEW Point-to-Point wireless feature, and the shops network (CAT5, or Wireless).

The teck 2 scanner is able to check all GM before 2009

I  just did a “Fast-Learn” on a G8’s 6L80E last week with mine. A Snap-On MODUS was not able to do this. There are simply factory diagnostic procedures that a T2 can do on GM vehicles that no other tool can. But yes, to reflash PCM’s, TCM’s, etc, you need to have authorization from the Tech Center, which means you have to be a dealership or a paying subscriber to the service which is a serious chunk of $$$$.

With that said, Bosch (who now owns the rights to GM Tech 2‘s as they purchased out Vetronix), will not support the unit because it’s a factory knock-off. So should you have to replace the VCI module (I’ve had to replace mine due to wear and tear on the connection where it damaged the motherboard inside), or any other necessary repair.

Also, T2’s can only be updated through 2009 MY vehicle info, was my understanding from GM. For 2009+ GM has gone to a new setup called MDI. GM MDI is backwards compatible with pre-2009 GM vehicles (it even has the software on the screen to emulate the screens you’d see on the T2).

So is this teck 2 scanner able to check all GM before 2009 obd2 with out extra software? Also wonder if it can check the cam/ distributor retard timing on vortex 350

I think the GM MDI system will go back to 2009, but the Tech2 seems to work as far as its updated. Obviously I don’t have any 2012-2013 vehicles to try it on though.

It will work on any Car Diagnostic Tool GM OBD2, meaning 1996+.

Here you can see its updated to 2013.
