Strange 24 Deg base timing - STi 32bit

[dynamix]

I have been using Enginuity to modify my ecu rom on my 2.5 EDM STi

When logging deceleration it shows up a base ignition timing value of 24 degrees. This is when load is around 0.22 and running down through the revs to about 3500rpm.

There is a table in the ECUedit software / xml defs that open this as Base Ignition Timing A but is only a 2 x 2 table.

For 1200 rpm and 0.25 load this shows as 21 ish deg
There is a flat 3.16 deg value in the Enginuity table Timing Compensation B (intake Temp)

Would this be where this value is coming from?

I am wanting to reduce timing in these loads cells right down to a low value - but wanted to know why it is adding it in there to start with.

Any ideas?

I have amended the ml to include that table in enginuity and reflashed it back on but still giving the 24 deg min advance on deceleration.

Any idea where this base level is set ?

When EGR, the ecu leans the mix (even though WB will still report 14.7) and can advance timing up to 8* or so degrees.

Pulling advance at these areas can make engine run stupid
