Extended Parameter definition?

Hello,
How possible is it to find extended parameters for a ROM? Few extended parameters are defined (IAM, FBKC, Max Wastegate Duty). I'm hoping to find Manifold pressure direct

Kind regards,

For which ROM ID?

The ROM ID is: 2A04446305

One of the rarer ROMs. From the JDM AT Forester. I've attached it.

Does this work?

Code:

<ecuparam id="E52" name="Manifold Relative Sea Level Pressure (4-byte)*" desc="E52-Same as Manifold Absolute Pressure (Direct) except represented as relative pressure with the assumption of sea level." target="1">
  <ecu id="2A04446305">
    <address length="4">0xFFA354</address>
  </ecu>

Looks right. Thanks alooot!
Updated the image to include units

Hey dschultz,
Can I trouble you with another parameter?

A/F Learning #1/#2 A-D (Stored)

I essentially want to see learning view, as I'm trying to dial in decapped injectors

Kind regards,
Daniel

For RR Learning Tables View to function you'll need to defined these parameters in the logger.xml at a minimum (IAM 4-byte you already have).

Code:

<ecuparam id="E41" name="Fine Learning Knock Correction (4-byte)*"
                    <ecu id="2A04446305">
                        <address length="4">0xFFB040</address>
                    </ecu>

<ecuparam id="E44" name="A/F Learning #1 A (Stored)*"
                    <ecu id="2A04446305">
                        <address length="4">0xFF8054</address>
                    </ecu>

<ecuparam id="E45" name="A/F Learning #1 B (Stored)*"
                    <ecu id="2A04446305">
                        <address length="4">0xFF805C</address>
                    </ecu>

<ecuparam id="E46" name="A/F Learning #1 C (Stored)*"
                    <ecu id="2A04446305">
                        <address length="4">0xFF8064</address>
                    </ecu>

<ecuparam id="E47" name="A/F Learning #1 D (Stored)*"
                    <ecu id="2A04446305">
                        <address length="4">0xFF806C</address>
                    </ecu>

In your ECU def XML you'll need:

Code:

<table type="2D" name="Fine Correction Rows (RPM) " <!-- note the space between the ( and ", it's important! -->
<table name="Fine Correction Rows (RPM) " storageaddress="0x6A508" />

<table type="2D" name="Fine Correction Columns (Load) " <!-- note the space between the ( and ", it's important! -->
<table name="Fine Correction Columns (Load) " storageaddress="0x6A4EC" />

<table type="2D" name="A/F Learning #1 Airflow Ranges"
<table name="A/F Learning #1 Airflow Ranges" storageaddress="0x65608" />

Here are all the extended parameters I've found so far:

Code:

E_AF_Correction_1_4byteExt_E81                      FFFFA610 
E_AF_Learning_1_4byteExt_E48                        FFFFA5B8 
E_AF_Learning_1_A_StoredExt_E44                     FFFF8054 
E_AF_Learning_1_B_StoredExt_E45                     FFFF805C 
E_AF_Learning_1_C_StoredExt_E46                     FFFF8064 
E_AF_Learning_1_D_StoredExt_E47                     FFFF806C 
E_AF_Learning_Airflow_Range_CurrentExt_E61          FFFFA5C1 
E_Closed_Loop_Fueling_Target_4byteExt_E121          FFFFA658 
E_Engine_Load_4ByteExt_E32                          FFFFA2A8 
E_Feedback_Knock_Correction_4byteExt_E39            FFFFB01C 
E_Final_Fueling_Base_4byteExt_E123                  FFFFA510 
E_FineLearningKnockCorrectionRamTable_E173          FFFF80F0 
E_Fine_Learning_Knock_Correction_4byteExt_E41       FFFFB040 
E_Fine_Learning_Table_OffsetExt_E58                 FFFFB04E 
E_IAM_4byteExt_E31                                  FFFF80DC 
E_Knock_Correction_Advance_IAM_onlyExt_E40          FFFFB034 
E_Manifold_Relative_Sea_Level_Pressure_4byteExt_E52 FFFFA354 
E_Primary_Open_Loop_Map_Enrichment_4byteExt_E84     FFFFA74C

Dear dschultz,
would you mind sharing a def file with the above parameters? Am not familiar with inserting the code in the file.
