If anyone knows the right sequence of bytes to send, I can add that to PCM Hammer. I need to do a crankshaft relearn on my own car. 
Went to a shop today who said they could do it, but the only employee who knows how was out on vacation today.

GM tech 2 nano clone software I have seen these on Amazon and wondered how they work and if they would be useful for working on your own vehicle? I have a 2010 4.8 and a 2013 5.3. I have a generic scanner, but would like something with bi directional capabilities that is not expensive and can do things like a crankshaft relearn. Thanks for any help you can provide!!!

I have merged your two threads on the "same" subject.
Sorry that no one has answered your questions.
I actually bought one the the cheap Tech-2 clones, but never got a chance to try it. On my Camaro I switched from the GM PCM to a Holley; I sold my track Corvette. Between the body and off-road shops I now own, I have various high end scanners.
For my Mercedes, I bought a Chinese clone of the dealership hardware scanner and that has worked well. For my BMWs the factory engineering software is available in "bootleg" form, although some of the paid smartphone apps are very good.
I suspect the Tech-2 clone works, although with a learning curve.

It's an open-source app for Windows that lets you read and write the flash chip on P01 (aka 411) and P59 PCMs that were used in various LS-powered vehicles from about 1999-2007. After you read the chip you get a .bin file, and there's a free app called Tuner Pro that lets you edit the tune, as long as your PCM had a supported version of GM's software.
There's also a data logger.
It isn't HPTuners, but it's free software and it works with cheap hardware ($50-$100ish).
