The timing compensation tables (such as IAT B) will not appear in base timing, if you are logging 'ignition base timing*' the extended parameter in Enginuity's logger and not the standard 'ignition timing' which is total timing. I seriously doubt that the 2x2 base timing table is used. I removed these types of tables from the definitions a while back as I began to notice that this is generally Subaru/Denso's method of indicating that a table has been removed from consideration - meaning that some other model or year may use switching logic (say the non-USDM LGTs that have the old school SI-drive). So, rather than recode the entire routine for model that doesn't use it, they simply leave it the same but manipulate the map ratio multiplier to always be one value (so only one of the tables is used for example) and resize the "appendix" map. Anyway, there are quite a few elements to timing that still need to investigated. Likely this is one of them. If you want to figure this out, I can send you some custom logger defs to try to isolate the issue (and rule in or out the 2x2 table as well). Just PM me your rom id on the OpenECU site.
