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.

So values of 0.000 would be 100% DI, right?
Well, using the stock compensation table there was at least a +- 4~5% fuel trim variation in closed loop due to temperature in lower intake volume closed loop operation. I dialed in a maf scale at approximately 66~72f IAT's. When ran within that temp range fuel trim were below 2% in closed loop. Once the temperature gets higher the the fuel trim would change pretty proportionately to the amount of IAT increase leading me to believe the temp compensation needed to be adjusted.
