Part 1: GM MDI or Tech 2

Tech 2 scan tool has become obsolete for shop use as of late. It still has a lot of capability and will do anything you need for the older platforms but it needs the CANdi module to work with any of the new stuff. The MDI is a 1 shot deal for all the newer PCMs and will still work on the older stuff too. I sold my Tech 2 and bought an MDI last year, haven’t missed the Tech 2 since. Then again I’ve got a Genysis scanner I use for all my typical diagnostics & probing.

However, the MDI requires a GM log-in with monthly access to GM’s website. That’s it’s only draw back for the enthusiast who wants a GM caliber scanner. The Tech 2 can be updated within itself and doesn’t require the internet, the MDI does.

If you’re running a shop, get an MDI. For the garage warrior or enthusiast, get a Tech 2. Just don’t fall for these $350 pieces of garbage.

You can say that, Tech2win is a pain the the butt. It never updates security correctly for the 30 day window and that using GM computers and login info. The tech 2 is great for code reading, viewing data. The MDI is pretty much only used for programming but its needs on certain 10+ platforms and all 15+ to view data through GDS. All MDI functions require a GM subscription.

Part 2: Tech 2 original or clone?

First, How to find the original or fake.

It is very simple. The first thing I look, it’s the memory card slot, open it up and look at the cover, if you see the stamp of the body exactly original. Next, the original at all wires and Candy use aluminum. As different numbers on the back cover, the photo you will see the difference. Sometimes it comes and all labels need to glue yourself.

Second, worth to have a Tech 2 China clone?

In short, that is a nice piece of equipment to have, very nice!

Aside from working beautifully with OBD2 Scanner, the tech2 is the scanner for GM OBD1 to use. with the right software (plug in chips like nintendo cartridges) it’ll do some daewoo/suzuki, GM medium duty (meaning bigger than 3500 using non automotive OBD2 standards), and other in the GMdistant family tree too.

In addition to generic codes (P0000-P0999) It’ll do all the proprietary GM codes (P1xxx), actuators, and systems. you can also view fuel trims, emissions readyness (beyond a green LED for all OK) and It’ll talk to ALL the modules rather than just the ECM (and if you get into the $250+scanners, ABS) like BCM, SIR, entertainment, EVERYTHING on a GM. At school I used one with a 91+ cartridge on my 87 S10, so going back further is hit or miss but posible.

To adjust shift points and fuel consumptiona and Speedo, forget it.

The Professional Diagnostic Tool TECH2 can’t do any sort of modding/tuning, only upload GM flashes. At least with legitimate software. I’m sure someone has custom software to do it but there are easier ways nowadays.

Is it worth if you just want to read/clear codes on your own car once in a while, heck no. If you’re doing a lot of work on GMs or want to get a lot more in depth with your car, it’s worth the money.

No comment on China knockoff quality, I mean a working tech2, Chinese made or not.

Tech 2 scan tools are verified working:

All of GM Tech2 are same functions,they are just from different factory.
SP23,SP23-1 the same,just the package case is different,one is with plastic case,one not.
SP23-B,SP23-B3 the same factory,the packing is different,one is with plastic case,one not.

Reviews talk a lot. Use with relief.
