Device: GM Tech2 Clone
Car: Corvette C6 2005- 2013
this scan tool is a massive beast, in the pictures it looks smaller but damn! This thing is hefty and looks like one of those TV walkmans’s from the 80’s. hahaha
It can do so so much more than a simple OBD2 scanner:
Overall technical ability of this GM Tech2 Clone 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.
FYI, I purchased Tech2 Clone 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.
