I ordered a clone off obdii365 and have used the Tech2 for about a week. First impressions were that this scan tool is a massive beast, in the pictures it looks smaller! This thing is hefty and looks like one of those TV walkman's from the 80's. Overall technical ability of this thing is amazing, I bought it to ensure my steering wheel was at zero after steering rack removal for a harmonic balancer; works great! After pulling DTCs from every single module in the car, I soon realized I had fault codes that a regular OBDII reader would never capture which is pretty awesome! While playing around with it more, I found where you can adjust the engine idle RPM speed and adjusted it up to 625 from the pre-set 550 RPM. This minor adjustment to the idle speed actually made my Corsa Sport exhaust sound more throaty and aggressive at idle, you should try it. I wouldn't think this small idle adjustment would damage anything.
The one i purchased came with the latest GM software version 33. something....This version covers GM vehicles up to 2013. Keep in mind the Tech2 is only a diagnostic tool, used to test different modules and perform numerous tests as well as special functions which are extremely useful. If you want to program or re-flash a module such as the BCM, the Tech2 serves as a pass thru device and you need a subscription from the AC Delco website to perform calibrations or updates to modules.
Overall, I recommend you get one! This huge beast looks like it came from the 80's, but it can do so so much more than a simple OBD2 scanner.
Anyway, wanted to share my Tech2 clone experience with everyone!

I ordered Tech 2 here on Nov. 4th, received it Nov. 9th. It shipped from China via DHL. I was able to get security access and program my CIM in my 2005 9-3. The Tech 2 works well, it's been able to do everything I've needed it to do, including programming the CIM and reading/clearing DTCs.

recently bought a tech2 clone here. Works great. No complaints. I was able to activate the afterblow feature, do TPMS relearn, and FOB reprogramming. IT came with the latest software.

i paid for this tech2 clone.... 4 months ago .... still works great. recommended

So far the tech2 clone works fine. It is useful for diagnosing and testing various things and systems on the vehicle. Has a LOT of built in test abilities like crank position sensor variation relearn, troubleshooting the ABS (4WAL) system, can also change the tire size installed (also in the ABS menus) which recalibrates the speedo as well as adjusts the shift points and transfer case (I'm not sure offhand what tire sizes it shows for an H2 but I'll check), can recode replacement stock stereos, test all lighting, injector balance tests, recalibrate the HVAC blend door actuators, literally can activate/test pretty much everything electrical on the vehicle in addition to reading and clearing any codes, and if using additional software update the software on certain modules. Most all other "code reader" devices can just check and clear codes.

I bought the SP23-B version and worked beautifully.

Thank you ,received GM TECH2 with everything good.

Just arrived this week, it's a clone but it works and I got the Candi module and all the accessories. I've also bought an old Dell laptop with XP and a real com port and have ordered the TIS2000 software CD/dongle.

Thank you ,received GM TECH2 scanner. do you have GM online programming account for sale ?

I bought a cheap Tech 2 hand-held unit shipped from China and it does what I need it to do well. I recently used my Tech 2 to help with my brake bleeding. The cheap Tech 2 was able to use the ABS auto bleeding and function test perfectly. No complains from me about my clone Tech 2 unit.

I just received my Tech 2 diagnostic scanner. I followed the initial startup instructions that went well. I turned the scanner off, and installed the Saab memory card, and the screen came up like it should. after I turned it back on, it stated "No PCMCIA card inserted". I tried reseating card several times until it finally came up normal with Saab on the screen. If I turn the scanner off, and back on, it will most of the time give me the same "No card" message. could this be a defective PCMCIA card? If so, could I please have a replacement. When I did get it to work, the scanner worked great. but, the card, is so on and off, I think it must be defective. This is for Saab. Thanks, Douglas Brown

I need a device to exercise my EBCM/ABS Pump for TCS Code 1243 (Slow BPMV - Brake Pressure Modulator Valve). Will any of the SP23 products do this? With the TIS2000, of course.
