Very good question. I wonder if it is a product of having 2 set of engineers wanting to combine their programming routines into a bastard child and neither wanting to give ground or rewrite their routines. Indirect addressing would allow both sets of engineers access to similar values using, for example, SSM or Toyota mode 21 switches. Would be interesting to see if later Subie ROMs have the same amount of indirect addressing.

I think Colby's params come from the OBD call routines, and the data comes out ordered similarly to an OBD mode 01 list.

When I was chasing the MAF_V parameter, I found somewhere between 6-8 MAF (g/s) parameters, some of which were used for IAT and ECT compensation, some of which just sat as duplicates. There were also a few 8 and 16 bit MAF values that had been reconverted from float values sitting around memory.
