why i'd like to do this? it's nice having PIDs & OBD-II rationality vs. OBD-I's sensing only complete failures.

source? The Wiki says you're wrong..

And I've heard from a fairly reliable source that OBD-II was a big reason they pulled the plug on the FD in the US.

If all you want is datalogging, why don't you invest in a nice aftermarket ECU? It's going to be a lot (read, a whole lot) cheaper for you in the end and provide you with more control so you can do something with that data.

Datalogging & freeze frame data is only a partial reason.

Contrary to popular belief, America does not set the regulations in other countries. Just because all cars sold in America after 1996 had to be OBD-II compliant doesn't mean cars in other nations had to be OBD-II compliant. Same goes with TPMS. Just because the ASE and DOT say it is so for America does not make it so for anyone else. They have 0 power in any other country.

I guess you can do it. You'd need some way to interface with the Mazda ECU through the diag port. And then a HUGE table that then translates it to an ODB2.
I just don't understand why you'd want to go through all the trouble. Once you have the interface from the diag port to the ECU, why go the extra step and make it ODB2? The data is already there

All cars sold in the US were required to have OBD2 effective Jan 1, 1996. OBD2 is not a global standard. You are chasing a dream. With all of your training i would think you would understand what it takes for a car to meet OBD2 standards.
