Is there a good obd2 tool/device that can scan all my vettes diagnostics like air/fuel, intake temp, etc. if you have any suggestions let me know!

 

We use the wired version of this one. Tons of features. You can even get GM custom PIDs like transmission temp.

I don't know of any scan tool that can do A/F.

 

Does this access the ABS, airbag and propriatary modules for the C5? Most OBD2 scanners won't.

I recommend a MDI clone or vxdiag nano, which will show you everything a factory tech2 can.

 

No. Its an obd2 scanner with some custom pid support.

 

IMO if your getting a scan tool you really need one that can interface with every module.

 

I have a Tech 2 but I also use this:

When i purchased mine I also brought a 5ft extension cable so I can have the unit under the hood while working on it.
And the ABSOLUTE Best part is..............you can get it for about $150.00

 

^ that is a really cool unit at a very good price.

OP asked for obd2. So that is what I replied to. Of course it is his choice and maybe he meant that he wanted more that obd2.

 

Does the Launch Tech CRP123 allow you to view historical vehicle trouble codes even if the check engine light is off? Thanks.

 

Yes it will show stored History Codes.
