== Introduction ==
This document supplements the [https://github.com/dmacpro91/BMW-XDFs B58 XDF files] and invites contributions in the form of pictures, additional descriptions, useful formulas, relationships to other tables and other notes which provide intuition to tuners.
This document has been generated from the XDF. If you wish to edit the table descriptions, you might find more sensible groupings (for example, the knock detection tables for cylinders 1-6 would be better considered as a unit).
Some of the German table abbreviations are translated in [http://nefariousmotorsports.com/forum/index.php?topic=1353.0 the ME9 abbreviations page on Nefmoto]

The DME's lookup from load to torque. The torque values are ''indicated torque''. This is the torque from the combustion process and does include any friction. Driver torque limits are usually measured in ''clutch torque'' which includes friction in the engine but not the transmission. 
    Part of the ECU's lookup chain from the driver's torque clutch request to engine load needed,
 
    though the torque values here are indicated torque.  
An important feature of this table is that, when inverted, it creates a lookup of torque to load. This allows the DME to calculate the load target given the driver's torque request.
    According to ECUTek, the load breakpoints create an implicit load limit so tunes will want to rescale the breakpoints.
 
When creating tunes, it is useful to have this inverse table to hand, in order to get a feel for the load the DME will target. This can be done by hand, although that is quite tedious and, if you rescale the breakpoints, you will have to repeat the process. For that reason a spreadsheet or script is better. The picture below gives an idea of the process.

When we do this, the torque to load table looks as follows. (Be aware, the right of the table includes some numerical error):

We should add finally that this is a very simplified view of the DME's calculation which involves hundreds of values. The load target you see in logs might differ.


=== Load limit due to EKP maximum value ===
=== Load limit due to EKP maximum value ===

'''Notes''':


   This is KW to the stage-1 map effectively removes the limit here. Agree that it appears redundant.
   Can be set to a much higher value such as 500 kW for stage 1 or 2 tunes.
 


=== Max Torque at clutch (monitoring) ===
=== Max Torque at clutch (monitoring) ===

'''Notes''':


This table is pressure ratio and airflow to turbine power (in kW). It can be thought of as the ''how hard and fast to push the turbo map''. It can also be thought of as the handoff between the intake side and exhaust side of the turbo in that the power required from the compressor (to provide boost) becomes the target for the exhaust turbine.


'''Notes''':
The actual power target has to be corrected for temperature, using a formula, because there is no temperature axis here.


  The stage 1 map has extended the y-axis breakpoints (airflow in g/s) from 389 to 500.
To gain some intuition about the power available from the exhaust, consider that if the '''engine''' is putting out 200Hp into the crank, but is only 33% efficient, there is another 400Hp gone somewhere. The turbo catches a chunk of this, so the turbine power can be surprisingly high. At the right of the stock table, for example, 59.4kW equates to about 80Hp. Even middling values in the table would power a lawn tractor.
  For comparison 500 g/s is roughly equivalent to the max airflow from an EFR7670.
  The stock turbo is reckoned to produce up to 385 g/s.
  This table is target pressure ratio vs


The stock table is well calibrated by BMW engineers (we assume). The problem for custom tunes with upgraded turbos is that the airflow can go beyond the axis limit of 389 g/s. In that case, one can look at ''compressor base kw'' and ''compressor after p-d kw'' logging parameters.

This is the max upward percentage correction to the boost setpoint (i.e. to the pressure ratio).


'''Notes''':
The x-axis is the amount of ''underboost'' hPa (300 hPa is about 4psi). It is important to note the sign, since it is counterintuitive (a -ve boost deviation is overboost and +ve one is underboost).


    This table is also maxed out, effectively removing floor and ceiling from the boost control setup.
The y-axis here is claimed to be the current boost setpoint. This is confusing or questionable. The floor and ceiling table y axes form a continuous set of values from 0.4 to 1.8. The correction floor table axis runs from 0.4 to 1.0 while the ceiling table from 1.0 to 1.8. So the ceiling table takes off where floor table stops. It's not clear why that would be.
    This is the max upward correction to the boost setpoint (i.e. pressure ratio) in %.
    The y-axis here is the current boost setpoint. The x-axis is apparently a quantity in hPa
    although 300 hPa is only about 4psi.
    Note that the floor and ceiling tables combined have continuous row pressure ratios from 0.4 to 1.8
    while the colums have continuous pressure from -300 to 300 hPa.
    Thus what seems to be happening is that if, for example, the p correction table were to demand a correction of -200 hPa,
    which is a downward correction, the value would be run through the floor table to get the maxiumum overall % adjustment.


These questions need not hinder progress because valid values are -100% across the entire correction floor table and +99% across the entire correction ceiling table.

    The stage-1 map rescales the row breakpoints to allow for more overall airflow.
The German translation for the description states: ''Correction of the pressure difference for the P component of the performance-based boost pressure regulator.'' It seems that 'pressure difference' here is the boost error. The relationship to the power-based P factor needs clarifying.
    EcuTek state the max flow of the stock turbo is about 385 g/s so this map has it covered.
    Boost correction in hPa where columns are required pressure in hPa and rows are airflow in g/s.

This table models the percentage of gas flow through the turbo as a function of total exhaust flow and wastegate position. For example, looking to the rightmost column, when the wastegate duty is 100%, the wastegate is fully closed and the turbo flow is 100%.


For tuning purposes, the rows only extend to 305 g/s of MAF. When maxing out the stock turbo, airflows of about 440 g/s are better and for hybrids, 550 g/s or so.

     The stock map value of 1 across the board applies to 95RON fuel whereas the fuel scalar is tweaked here for 98RON.
     The fuel scalar table is a map of RPM and load to fuel quantity multiplier. It acts to modify the fuel quantity that the DME injects in order to meet its lambda target. For normal 95 or 98 RON tunes, this table can be left as is but for ethanol and flexfuel tunes, it must be edited so as to maintain acceptable fuel trims. Edits to this table are also used to dial back DI fuel delivery in PI tunes. In that case, it is important to scale the breakpoints correctly.
    Note also that the stage 1 map actually sets the breakpoints according to the expected range of RPM and load whereas the stock map
    does not bother to do this.

     This table provides an AFR target for when the DME enters component protection mode. The stock values above are extremely rich, so we can see it is really shoving fuel to cool things down. Somewhat more reasonable targets around 12 are common.

'''Notes''':
    These exhaust flap maps provide the pedal position required to open the exhaust flap. To decode the names of these tables, AKR stands for resonator exhaust flap (Abgasklappe für Resonator). Suffixes are then CC for cabriolet closed (convertible tops with the roof closed or normal cars with a roof) and CO (convertibles with the roof open). Then AT (automatic shift mode) and MT (manual shift mode) and finally M (sport mode). For example, AKRGRCOATM is the map for a convertible with the roof open is auto mode with sport or sport plus selected.
    Additionally, there are base and VAR1, VAR2, VAR3 variants of each of the table above. There is a coding parameter (CodVar_stAKR) which determines which variant the car thinks it is. For practical purposes, it might be easier to focus on any differences between manual and sport modes and copy these settings into all variant slots.
    Astute readers will notice that MHD's ''exhaust flap always open in sport mode'' simply wipes out a ton of this pointless complexity. The downside of this is that the car can produce a drone if using sport around town. Custom tunes might therefore want to keep the flap closed below, say, 2000RPM.
  The tables above are not always active. The overall control of the exhaust flap is determined by a hierarchical decision process as follows:
* OBD testing tools like ISTA+ have top priority if they are activating the flap.
* At startup, the DME considers the engine temperature and car's speed. If the engine is warm, the flap is opened until an initial timeout expires. If the engine is cold, the flap will close once the car is moving.
* The DME might open the flap during cat heating depending on coding, options, car speed and RPM.
* Whether burble settings are enabled.
* The accelerator pedal position.

  Set to 2. Stock maps for some software versions have this set to zero. 1F052F is an error code that gets raised if the car accelerates 'too hard'. This can cause the car to shut down. Apparently, the feature operates to stop bad things like people flooring the accelerator accidentally when in traffic because their foot slips. A problem arises because the feature can be triggered wrongly because of wheel speed sensor problems or because tuned cars accelerate harder. If your car shuts down mid-pull (!!) you might want to revisit this.

  This is apparently some kind of DME self check. Custom tunes should set to 2 (possibly higher values will also deactivate).

Introduction

This document supplements the B58 XDF files and invites contributions in the form of pictures, additional descriptions, useful formulas, relationships to other tables and other notes which provide intuition to tuners.

This document has been generated from the XDF. If you wish to edit the table descriptions, you might find more sensible groupings (for example, the knock detection tables for cylinders 1-6 would be better considered as a unit).

Some of the German table abbreviations are translated in the ME9 abbreviations page on Nefmoto

Load

Performance gauge scaling

Brief description: KF_EDA_ANZ_SPORT_MDK_IST

Dimension: 2D, table

Categories: Load

Unit info: Nm, 1/min --> Nm

Breakpoints: Performance gauge scaling X (autogen) vs Performance gauge scaling Y (autogen)

Example: 

                0       50      100      200      300      500
       0        0       50      100      200      300      500
    1000        0       50      100      200      300      500
    2500        0       50      100      200      300      500
    4000        0       50      100      200      300      500
    5500        0       50      100      200      300      500
    7000        0       50      100      200      300      500


Notes: 

   A table of torque in Nm (presumably clutch torque) vs RPM. This suggests the table is fudging the value actually displayed on the guage given the clutch torque value determined.

Dimension: 1D, vector

Categories: Load

Unit info: 1/min --> %

Notes: The DME's lookup from load to torque. The torque values are indicated torque. This is the torque from the combustion process and does include any friction. Driver torque limits are usually measured in clutch torque which includes friction in the engine but not the transmission.

An important feature of this table is that, when inverted, it creates a lookup of torque to load. This allows the DME to calculate the load target given the driver's torque request.

When creating tunes, it is useful to have this inverse table to hand, in order to get a feel for the load the DME will target. This can be done by hand, although that is quite tedious and, if you rescale the breakpoints, you will have to repeat the process. For that reason a spreadsheet or script is better. The picture below gives an idea of the process.


When we do this, the torque to load table looks as follows. (Be aware, the right of the table includes some numerical error):

We should add finally that this is a very simplified view of the DME's calculation which involves hundreds of values. The load target you see in logs might differ.

Load limit due to EKP maximum value

Brief description: BMWlpa_rat_AirLimMax_C

Dimension: constant

Categories: Load

Units: %

Notes: 

 Stock, this is 200%, so tunes should increase this according to the desired max load.

Switch load limit component protection at rich lambda

Brief description: S_BSRFMX

Dimension: constant

Categories: Load

Units: -

Notes: 

 Set to 1 in stock, stage 1 and stage 2 maps so presumably no need to change. Component protection mode is the where the ECU calculates the exhaust is too hot and so makes the mixture richer and ramps down load. Presumably this toggles this behaviour or affects it in some way.

    1400     2600     3600     5000     6000     6500
   1.008    1.000    1.000    1.000    0.914    0.852


Notes: 

   An RPM-based table of torque multipliers normalized to 1. The factory table ranges from 1.008 at low RPM to 0.852 at high RPM. Presumably this is to a sort of nanny that makes the car feel a bit more punchy low down but safer at higher RPM. Setting to 1 across the board seems a better strategy.

Normierung für Mdk_ist_sot_mem_mx

Brief description: K_MDKIST_SOT_MX

Dimension: constant

Categories: Limits

Units: -


Example: 

 500.000


Notes: 

   A normalizing factor that looks like a clutch torque limit, upped to 550Nm for stage 1 and stage 2.

Max calculated power

Brief description: K_EDA_P_MAX_MOT

Dimension: constant

Categories: Limits

Units: kW

Notes: 

  Not used in the factor tune or in stage 1 and stage 2.

Load limit factor by rich for component protection

Brief description: K_FRFMXBS_MN

Dimension: constant

Categories: Limits

Units: -


Example: 

   0.500


Notes: 

   Multiplies the load limit by this factor if entering component protection mode. 
   Some tunes, like MHD's, set this to 1. Presumably they are relying on the richer mixture during component protection?

Max naturally aspirated volumetric efficiency

Brief Description: For naturally aspirated operation, should not exceed 100% KL_LAMX

Dimension: 1D, vector

Categories: Limits

Unit info: 1/min --> %

Breakpoints: Max naturally aspirated volumetric efficiency X (autogen)


Example: 

 100   120   163   175   225   250   275   300   325   350   450   475   500   520   540   600   675   695
92.0  92.0  92.0  92.0  92.0  92.0  92.0  92.0  92.0  92.0  92.0  92.0  92.0  92.0  92.0  92.0  92.0  92.0


Notes: 

   Seems like the XDF here might have the RPM values out by a factor of 10. MHD's tunes set this to 100% across the entire table, presumably to simplify calculations?

Torque request ceiling

Brief Description: BMWtqe_tqc_FlApplStgNorm_T

Dimension: 1D, vector

Categories: Limits

Unit info: 1/min --> Nm

Breakpoints: Torque request ceiling X (autogen)


Example: 

  800   900  1000  1250  1380  1500  1520  2000  2500  4500  4750  5000  5200  5500  6000  6500  6750  7000
500.0 500.0 500.0 500.0 500.0 500.0 500.0 500.0 500.0 500.0 490.0 474.0 458.0 434.0 398.0 368.0 353.0 333.0


Notes: 

  This table acts as an upper limit on the driver's wish. This, in conjunction with the relative torque request tables (in the throttle maps category) provide the driver's torque request to the ECU.   
   
   Tunes should generally remove the miserly tapering of torque found in the stock map above. Note the breakpoints can be tweaked to give lower or higher granularity at specific RPM ranges. Remember, the use of 'ceiling' is confusing here. It represents the driver's wish,
   
   The values look like clutch torque.

Switch recognition stalling

Brief description: BMWmondmf_swi_StallStru_C

Dimension: constant

Categories: Limits

Units:


Example:

Notes: 

   Not sure what this is. Could it have been translated backwards and actually mean 'stalling recognition switch'? Still not sure why it would do even then.

Max power (monitoring)

Brief description: MoFTrqPtd_pwrMax_C

Dimension: constant

Categories: Limits

Units: kW


Example: 

250.0000


Notes: 

  Can be set to a much higher value such as 500 kW for stage 1 or 2 tunes.

Max Torque at clutch (monitoring)

Brief description: MoFTrqPtd_tqCluMax_C

Dimension: constant

Categories: Limits

Units: Nm


Example: 

 500.000


Notes: 

  Tunes should set to a sensible upper value.

Maximal actual torque

Brief description: MoFTrqAct_trqPtdInjActv_C

Dimension: constant

Categories: Limits

Units: Nm

Notes: 

   Not clear. The factory sets this to 600Nm, which is above its clutch torque limit. This might suggest it's not used by the factory tune and that other tunes can just lift it out of the way?

Max allowed actual torque, injection active.

Brief description: MoFTrqAct_trqPtdInjActv_C

Maximum indicated torque (Nm)

Brief description: EngDa_tqInnrMax_C

Dimension: constant

Example: 571.0

Categories: Limits

Units: Nm

Notes: 

  The factory sets this to 571Nm, which is about 15% about the clutch torque limit. This suggests other tunes should set this according to their clutch torque and not just lift it out of the way.

Notes: 

   According to https://f30.bimmerpost.com/forums/showthread.php?t=1734153,
   the axes here are km/h vs % (of the accelerator). 260 km/h is 160 m/h.
   The output is also %, thus we can think of the table as a speed dependent modulation
   of the pedal.
   The torque request is reduced at lower speeds but increased at higher speeds. The
   effect is to prevent the car being too jumpy in traffic but more responsive when the
   car is moving.

Notes:

This table is pressure ratio and airflow to turbine power (in kW). It can be thought of as the how hard and fast to push the turbo map. It can also be thought of as the handoff between the intake side and exhaust side of the turbo in that the power required from the compressor (to provide boost) becomes the target for the exhaust turbine.

The actual power target has to be corrected for temperature, using a formula, because there is no temperature axis here.

To gain some intuition about the power available from the exhaust, consider that if the engine is putting out 200Hp into the crank, but is only 33% efficient, there is another 400Hp gone somewhere. The turbo catches a chunk of this, so the turbine power can be surprisingly high. At the right of the stock table, for example, 59.4kW equates to about 80Hp. Even middling values in the table would power a lawn tractor.

The stock table is well calibrated by BMW engineers (we assume). The problem for custom tunes with upgraded turbos is that the airflow can go beyond the axis limit of 389 g/s. In that case, one can look at compressor base kw and compressor after p-d kw logging parameters.

Perf display scaling - power

Brief Description: K_EDA_P_ANZ_SPORT_BS_SCAL_CODE

Dimension: 1D, vector

Categories: Boost

Notes:

The guages work by splitting the power dial into 8 sections and then exposing parameters which define the power per section of the guage.

The allocation of cells according to units is as follows:

Note, that the tunerpro setup defines these as arrays, but the DME has them as individual values K_EDA_P_ANZ_SPORT_BS_SCAL_CODE0, K_EDA_P_ANZ_SPORT_BS_SCAL_CODE1, K_EDA_P_ANZ_SPORT_BS_SCAL_CODE2, K_EDA_P_ANZ_SPORT_BS_SCAL_CODE3 and values are in reverse order. Thus the correspondence with units is

  • CODE0 --> kW
  • CODE1 --> kW
  • CODE2 --> PS (i.e. metric HP)
  • CODE3 --> other

The other slot tells the DME's what to do in case is receives a nonsense unit so can be left stock.

PID correction ceiling

Brief description: BMWtchdiag_pct_WgPLo_M

Dimension: 2D, table

Categories: Boost, WGDC

Unit info: hPa, - --> %

Breakpoints: PID correction ceiling X (autogen) vs PID correction ceiling Y (autogen)

Example: 

                0      100      200      300
     1.0   12.103   11.551   10.449   -0.003
     1.4   11.551   10.449    3.299   -0.003
     1.6   10.449    3.299    1.099   -0.003
     1.8   -0.003   -0.003   -0.003   -0.003

Notes:

This is the max upward percentage correction to the boost setpoint (i.e. to the pressure ratio).

The x-axis is the amount of underboost hPa (300 hPa is about 4psi). It is important to note the sign, since it is counterintuitive (a -ve boost deviation is overboost and +ve one is underboost).

The y-axis here is claimed to be the current boost setpoint. This is confusing or questionable. The floor and ceiling table y axes form a continuous set of values from 0.4 to 1.8. The correction floor table axis runs from 0.4 to 1.0 while the ceiling table from 1.0 to 1.8. So the ceiling table takes off where floor table stops. It's not clear why that would be.

These questions need not hinder progress because valid values are -100% across the entire correction floor table and +99% across the entire correction ceiling table.

Notes:

The German translation for the description states: Correction of the pressure difference for the P component of the performance-based boost pressure regulator. It seems that 'pressure difference' here is the boost error. The relationship to the power-based P factor needs clarifying.

Notes:

This table models the percentage of gas flow through the turbo as a function of total exhaust flow and wastegate position. For example, looking to the rightmost column, when the wastegate duty is 100%, the wastegate is fully closed and the turbo flow is 100%.

For tuning purposes, the rows only extend to 305 g/s of MAF. When maxing out the stock turbo, airflows of about 440 g/s are better and for hybrids, 550 g/s or so.

Notes: 

   The fuel scalar table is a map of RPM and load to fuel quantity multiplier. It acts to modify the fuel quantity that the DME injects in order to meet its lambda target. For normal 95 or 98 RON tunes, this table can be left as is but for ethanol and flexfuel tunes, it must be edited so as to maintain acceptable fuel trims. Edits to this table are also used to dial back DI fuel delivery in PI tunes. In that case, it is important to scale the breakpoints correctly.

Notes: 

   This table provides an AFR target for when the DME enters component protection mode. The stock values above are extremely rich, so we can see it is really shoving fuel to cool things down. Somewhat more reasonable targets around 12 are common.

EGT Pre-cat Ceiling for switch to component protection

Brief description: KF_TA_VKSOLL

Dimension: 2D, table

Categories: Fuel

Unit info: 1/min, % --> °C

Breakpoints: EGT Pre-cat Ceiling for switch to component protection X (autogen) vs EGT Pre-cat Ceiling for switch to component protection Y (autogen)

Example: 

         2250.000 3000.000 4500.000 6500.000
  40.000  900.000  900.000  900.000  900.000

 180.000  900.000  900.000  900.000  900.000


Notes: 

   Stage 1 increases the calculated exhaust temp required for a switch to component protection mode.
   But note the fuelling change to richen the mixture below.


EGT Cat Ceiling for switch to component protection

Brief description: KF_TA_IKSOLL

Dimension: 2D, table

Categories: Fuel

Unit info: 1/min, % --> °C

Breakpoints: EGT Cat Ceiling for switch to component protection X (autogen) vs EGT Cat Ceiling for switch to component protection Y (autogen)

Example: 

            0.000 2000.000 4000.000 7000.000
   0.000  950.000  950.000  950.000  950.000

     3.5      3.5      3.5      3.5


Notes: 

  Max rail diff in MPa (1 MPa = 10 bar). Given that the fuel system operates at 200 bar,
  the 90 bar set in the stage 1 map is basically removing this limit, except in failure
  scenarios.

Notes: 

   The curious thing about this table is that the rows, which are in units of Nm, are only scaled to 350 Nm.
   The setpoint in this single injection table is equal to the multiple injection table.

   Interesting how, here, the stage 1 map is totally rewriting what it things the timing should be as the turbo is spooling.

Notes: 

   In this mode of operation, the stage 1 map thinks it can get 15 degrees of timing on 98RON fuel at max load.
   Stock map says 12 degrees and that seems a more reasonable number.

Breakpoints: AKRGRCCAT X (autogen) vs AKRGRCCAT Y (autogen)

Notes: 

   These exhaust flap maps provide the pedal position required to open the exhaust flap. To decode the names of these tables, AKR stands for resonator exhaust flap (Abgasklappe für Resonator). Suffixes are then CC for cabriolet closed (convertible tops with the roof closed or normal cars with a roof) and CO (convertibles with the roof open). Then AT (automatic shift mode) and MT (manual shift mode) and finally M (sport mode). For example, AKRGRCOATM is the map for a convertible with the roof open is auto mode with sport or sport plus selected.
   Additionally, there are base and VAR1, VAR2, VAR3 variants of each of the table above. There is a coding parameter (CodVar_stAKR) which determines which variant the car thinks it is. For practical purposes, it might be easier to focus on any differences between manual and sport modes and copy these settings into all variant slots.

   Astute readers will notice that MHD's exhaust flap always open in sport mode simply wipes out a ton of this pointless complexity. The downside of this is that the car can produce a drone if using sport around town. Custom tunes might therefore want to keep the flap closed below, say, 2000RPM.

  The tables above are not always active. The overall control of the exhaust flap is determined by a hierarchical decision process as follows:
* OBD testing tools like ISTA+ have top priority if they are activating the flap.
* At startup, the DME considers the engine temperature and car's speed. If the engine is warm, the flap is opened until an initial timeout expires. If the engine is cold, the flap will close once the car is moving.
* The DME might open the flap during cat heating depending on coding, options, car speed and RPM.
* Whether burble settings are enabled.
* The accelerator pedal position.

1F052F

Brief description: Drive, safety function: Acceleration reduction

Dimension: constant

Categories: Toggles

Units:

Notes: 

 Set to 2. Stock maps for some software versions have this set to zero. 1F052F is an error code that gets raised if the car accelerates 'too hard'. This can cause the car to shut down. Apparently, the feature operates to stop bad things like people flooring the accelerator accidentally when in traffic because their foot slips. A problem arises because the feature can be triggered wrongly because of wheel speed sensor problems or because tuned cars accelerate harder. If your car shuts down mid-pull (!!) you might want to revisit this.
