diagnostic scanner For you guys who have LS swaps in your pre 96 cars. What diagnostic scanner are you using? I have a 67 Camaro with an LS3 & found most over the counter diagnostic scanners at Napa/Autozone & ORiellys will not work on pre '96 cars and they want the VIN's entered & they will not accept the old shorter VIN's. What are you using?

Use the original VIN that came inside the PCM for the LS3 or I will send you one from my list of perhaps a dozen or more. It matters little that your car is a 67 Camaro because your PCM is modern, post 1981, and will have the now standard 17 character VIN inside its PCM. I use a Bluetooth ELM327 module to read 30 or so different OBD2 parameter stream item and my Android tablet uses several different free or very low cost apps: OBDLink, Car Scanner, OBD Fusion, Torque and Motor Data OBD. Most of these apps have a logging capability but usually not a freeze frame capability. Misfire counts are also lacking but they will detect misfires.
Where is the OBD2 data port connector in your Camaro?
My Bluetooth hardware is either a Chinese Konnwei device, Nexas Nexlink or an OBDLink MX. I've also got a VXDiag "Nano" but I don't recommend it. These types of hardware devices can't do everything that the HP Tuners MPVI3 can do but I'm a cheap tight wad. Fortunately, I don't need HP Tuners very often though a coworker may about be ready to sell his MPIV3 for cheap.

How are you controlling the engine? I would imagine most folks are running a 0411/P59 ECU and wire up an OBD2 port, then you can plug in any scanner as if the vehicle was a late 90s/early 2000s.
I don't the VIN has much to do with reading stuff like codes and live data. You can program a VIN on the ECU with HP Tuners, et. al.
I'm not sure if any of this applies if you are using an aftermarket ECU like Holley though...
VIN numbers have been 17 characters since....hell I can't remember
Pre-96 cars are going to use the OBD1 style connector.
You are going to need an OBD2 port/scanner to talk to your LS3 unless you are using an OBD1 computer.
With an "off the shelf" scanner, if you know what year/vehicle the PCM came out of, you can do it that way. If you are using HPTuners, it doesn't matter if you know or not.
I'm a little lost with what exactly you have going on here...
