I think i found some of the RPM Resume thresholds below. Having pulled the roms apart yet but im 99% these are right so far. Good starting point if someone has their rom broken down.

05 OUTBACK XT A2WC552S
2D: C8100
X: C7470

08WRX AZ1E401A
2D: CB348
X: C8AD8

09WRX AZ1G401V
2D: CB934
X: C9098

NEED TO CHECK LAST ONE.

2010 WRX AZ1G701V
2D: CBE80
X: C95F4

Could someone find the addresses for AZ1G300F?

Thanks in advance.

Those are correct - -17 RPM delta, 0 initial enrichment, counters are 2000, 2500 and 3000 RPM, and tables goes down from 2400 to 950 RPMs.

The stock values that show up in RPM do not reflect those numbers.

Well - that's the table:
Code:
ROM:00079A14 word_79A14:     .data.w h'10            ; DATA XREF: sub_2B290:loc_2B31Eo
ROM:00079A14                                         ; sub_2B396:off_2B500o
ROM:00079A16                 .data.w h'800
ROM:00079A18                 .data.l h'C60F4
ROM:00079A1C                 .data.l word_C6C68      ; = 2.4e3
ROM:00079A20                 .float 0.1953125
ROM:00079A24                 .float 0.0

Check whether your scaling / template is correct.

Forgive me for asking. I am not a developer. Please help me understand where/what I need to do with this information. I understand how to cut/paste code like I posted but I do not understand where to utilize this information you just posted. A point in the right direction is all I really need.

Thanks in advance.

That is a lookup table, and the following lines represent the Axis and Data addresses.

Code:
ROM:00079A18                 .data.l h'C60F4 AXIS
ROM:00079A1C                 .data.l word_C6C68      DATA


First line indicates the table has 16 entries.

The problem exists in your table's scaling.

From Github Alpha definition 32BITBASE:
Code:
<scaling name="OverRun Fueling " units="units" toexpr="x*0.1953125" frexpr="x/0.1953125" format="%.0f" min="0" max="5000" inc="1" storagetype="uint16" endian="big"/>

   <table name="Overrun Fueling RPM Resume Threshold" category="ALPHA OverRun Fueling" type="2D" level="1" scaling="OverRun Fueling ">
      <description>This 2D table determines (on an ECT x axis) at what RPM the injectors switch back on from coasting (i.e. full lean, and injector pulse width at zero). This would be useful to those with much larger injectors than stock that have a problem with stalling out as the vehicle comes to stop / idle.</description>
      <table name="Coolant Temperature" type="X Axis" elements="16" scaling="DegreesF"/>
   </table>

Thanks Merp. STI2NR, plug the addresses into the above template and paste into your Ecuflash XML, that should sort you out.

Thanks Merp and td-d for your valuable time. That fixed the issue I was having. A little help goes a long ways. :)
