C6 Scanning Tools...Where Do I Get One
I just read that you must have a scanning tool for C6 codes....since I plan on keeping my 427 for a looonnng time I want to buy one....where do I find good one??? Thanks....I suppose when I do get one I need books or something to know what the codes are.....and what to do...

You need to ensure that the scanner you buy can read a CAN enabled network. It is a newer OBDII communication protocol. A trouble code reader that is not CAN enabled will not work on your car. The packaging of the tool should say if it is CAN enabled.
As for knowing what the codes mean there are several options. Some of the more sophisticated tools will tell you what the code means right on the screen. Some will only tell you the code. If that is the case you can look up the codes online or the codes are of course in the service manual.
Most code tools will only read Powertrain Control Module codes which are prefaced with a "P" such as P0304. This type cannot read other codes such as those prefaced with "B", "C", or "U," To read those will need a tool that costs a lot more. However, Actron makes a tool that will read "C" codes associated with brakes.
"P" codes have to do with the emission system of the car as that is what OBDII was mandated by the government to monitor.
Some tools will also let you do real time monitoring of engine systems to aid in diagnosis of problems. These types of tools will also let you read "P" codes.
All of the scan tools that I have seen will let you turn off the Check Engine light.

There are so many options that you could go crazy looking at aftermarket scan tools.
Code readers, by design and federal requirements with the manufacturers, must be able to scan and read all OBD2 diagnostics, so you can get emissions control failures from any OBD2 capatible code readers.
Like Randy said, CAN will assist in monitoring OTHER SYSTEMS on that buss and read it accordingly.
If your just looking for something to get engine diagnostic codes, anything OBD2 capable will work.

Per federal requirements, you do not need a Can enabled device, only because that has nothing to do with OBD2 diagnostics and certs.
You can use an OBD 2 because the PCM MUST use OBD2 diagnostics and systems.
In the GM realm of engine controls, they actually use BOTH Class 2 and GMLAN in order to communicate with the different modules.
