Hey man alright, another newbie trying to decipher all this stuff. I am doing the same, just reading and reading some more. Also check out thirdgen.org. It's all camaro stuff but they have a ton of tbi info. I'm sure that some of the better guys like Fast305 or haulina$$ will chime in but yes the .bin is the code and yes the .xdf translates. I haven't yet datalogged but I'm pretty sure that the .ads files are the datastream files. Also, tunerproRT will datalog or winaldl. They are free, or just 30$ for tunerproRT. I would have to check for sure, but I bet you can get your .bin and .xdf files from moates.net. HTH.
By the way, what are you doing over there? Stay safe!!
