I'm still getting a bit of knock past 6300rpm with no modification to the Port to DI ratios. And my MAF scale with modified temp compensation runs really rich with cool IAT's and closer to 12.5:1 when IAT get hotter, in case you were wondering why it's so rich. I modified the MAF temp compensation to run with low amount of correction from 68f to 130+f IAT's in closed loop (1.1v ~ 2.8V maf volts). Open loop (2.8v ~ 4.2v)is not so ideal.

Like all maps... the highest value is applied for any higher input value on each axis. i.e. '5200rpm' means '5200rpm or greater'. also of course you can rescale any way you wish.

Temperature compensations are one of the many things that subaru engineers probably did better than we can. They just shouldn't need to be messed with IMHO, and i've never been in a situation where i had to.
