EAD15 , thanks for posting information about the VCX Nano. I was thinking about buying a Tech-2 Chinese clone for $300 to $400 and ran across some information about the VCX Nano on an other GM vehicle. From what I read, actual US produced GM cars, this VCX Nano works very well. Your post is the first report the VCX Nano works on an Aveo.
BTW I bought a new 2008 Aveo-5 in Dec 2007. It had 52K miles on it and I installed a new timing belt kit 2K miles ago and had some sensor correlation errors. I never touched the crankshaft sensor but I did take off the camshaft position sensor when I did the timing belt kit. My cam sprocket's timing marks were perfectly aligned but I much later determined the cam sprocket sensor needed to be mounter just a little closer to the center of the exhaust camshaft (forward) now the engine runs OK.
I have a question, does the VCX Nano do crankshaft sensor re-learn's like the Tech-2 does. I am guessing it does if it mimics the Tech-2. I watched a Youtube Tech-2 video do a crankshaft relearn in 4 minuets.

I still have the original TPMS sensors in my 2008. My Aveo friend still has the original battery (always uses a good battery maintainer) in his 2008 Aveo but his TPMS started going bad a year ago.
Again thanks for posting the VCX Nano information.
