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?
