Knock off GM TECH2 feedback on Corvettes C5: pay what it can do

I took several pictures of mine, quality of the cables and connectors and even the discs it comes with. you don’t need to download the manual , it’s on the data disk

The unit itself ….and the software CD’s … pretty good knockoffs, I think it’s like the others stated , it is a TECH II

gm tech unit-01

and here is the CANDI unit and cables ….. pretty high quality stuff along with one of the 12 volt adapters

And another shot of the data disks .. as you can see the labels were not made with an INK JET printer … and the a second cigarette lighter 12 volt power cable

and ….every cable and cable end you would need to connect to any GM car.

but wait, if you act today there is more …..

Personally, I can verify that they look to be the real CDs that come with the GM Tech 2 units.


GM Tech2 feedback on Corvettes C5:

-> Take 2011 Corvette LS3 for example, use it as a diagnostic tool /TCM reset tool , accessed the ABS and BCM modules and to turn on and off certain toggles etc.

-> Mine software is out of date, but I can get into most everything that I have tried to so far on newer cars. I used the “Global OBD II” under the VIN info page. I have not tried to program anything this way, but I have been able to access all the different modules on the CAN buss.

But I was suggested to update by getting the newest PC card from one of the online sellers, 2011 is the last update that GM did on the Tech 2 for Corvettes, so the newer units being sold all have the latest software already loaded on the GM card. Below is the latest card for GM for the Tech 2..From their site…

32MB Card for GM TECH2 (GM OPEL SAAB ISUZU SUZUKI & Holden) (Item No. SO22-C) $21.99

Their description: Works with GM TECH2, contain the latest software for GM TECH2. It has six kinds of software, SAAB, OPEL, GM, ISUZU, Suzuki and Holden. Customers can choose one type of software to be loaded to this 32MB Card.



Didn’t work on certain GM trucks


Overall, GM tech2 clone is a priceless tool, a $250.00 device does everything that the $5,000 device does …things that make you go ” Hmmmmm”. Besides, it works for more than Corvettes… there are a lot of repair shops that are using a knock off. Several users over on C5 have bought them and reports are positive from what I saw…


Where is the good place to have Tech 2 unit clone?

I bought mine from, because it’s working and sales at cheaper price after I learnt from this forum
