v0.13

Added Engine Coolant and Intake Air temperature scaling maps.
viewtopic.php?f=42&t=11143

Can you add the following to the v0.13:

Baserom 24k Partial MS41.1 0960:

Code:

  <table name="Engine Coolant Temperature - TCO" storageaddress="0x6F2">
   <table type="X Axis" storageaddress="0x64E" />
  </table>
  <table name="Intake Air Temperature - TIA" storageaddress="0x6C4">
   <table type="X Axis" storageaddress="0x635" />
  </table>

And to baserom 256kb full MS41.1 0960:

Code:

  <table name="Engine Coolant Temperature - TCO" storageaddress="0x146F2">
   <table type="X Axis" storageaddress="0x1464E" />
  </table>
  <table name="Intake Air Temperature - TIA" storageaddress="0x146C4">
   <table type="X Axis" storageaddress="0x14635" />
  </table>

Thank you!

Added as per Enabled's post above.

v0.15
Reorganized the map folders a bit. No new additional maps.

Need someone to test these tables that may be used during Cranking and/or Idle.

v0.17

Moved the 3 new maps from v0.16 out of the 'Unknown' folder and into their appropriate folders after confirmation by busterhax and Cloudforce.

Also added a map to adjust injector dead time as mentioned in viewtopic.php?f=42&t=11169

v0.19

- Changed software version recognition scheme. Now is 2 byte starting at xEh instead of 4 byte starting at xCh.
- Updated the formula for WOT enrichment to % after discussion with EVILM3666 and verifying in Siemens documents.

mrf582 · **Posted:** Thu Nov 06, 2014 5:23 pm

v0.20

- Added MAF Plausibility Check RPM Thresholds. Modifying these values will disable the check and should allow for Turbocharger tuning where the MAF can be very high even at low RPM and low Throttle.

Code:

<table type="2D" name="MAF Plausibility Check - Low RPM Threshold" category="Turbo" storagetype="uint8" endian="little" sizey="1" userlevel="1">
   <scaling units="RPM" expression="x*32" to_byte="x/32"  format="0" fineincrement="50" coarseincrement="500" />
   <table type="Static Y Axis" name="Set to a value above MAF Plausibility Check - High RPM Threshold to disable" sizey="1">
<data>Low RPM Threshold</data>
   </table>
   <description>If RPM is less than this value, MAF Plausibility Check will be disabled
   The ECU runs through a section of code to check for TPS and/or MAF plausibility to detect sensor errors that aren't due to simple disconnects. The ECU has a rough Alpha N map that knows how RPM, TPS, and MAF should relate to one another. If sensor readings fall outside of this range, it will throw a code for plausibility. For example, at 25% throttle at 3400RPM, you can run into a situation where the turbo has spooled up and is generating a lot of airflow. This would never happen in an NA engine so the ECU sees this extra air read by the MAF sensor and thinks something is wrong. But it only checks for this in a narrow window of RPM between 1504 and 3488 and TPS between 13% and 30% in stock form. We can change these thresholds to fool the ECU into never running this code by changing the RPM thresholds.

v0.21

- 3 of the unknown 4x16 maps were confirmed to be knock related so put them in their own 'Knock' folder
- Set the X and Y axis as MAF and RPM, respectively
- Set formula for table values based on Siemens Documents for MS42 and a wild ass guess
- Renamed the 3 different types of cylinder specific tables (Window Start, Window End, and Multiplicative Factor) assuming a firing order of 1 5 3 6 2 4 and their order of appearance in disassembly
- Changed most of the MAF axis from 'kg/hr' to 'mg/stroke' and updated the conversion formulae accordingly
- Renamed some of the DTC tables because I think they are actually 'error counter increment values'

v0.23

added switch to disable checksum for program section (256KB full read only) courtesy of Alec (d_munter)

added switches to disable OBD2 readiness monitoring for 5 systems (256KB MS41.2 full read only) *NEEDS TESTING*
Off-road and racing use only. Must NEVER be disabled on any vehicle driven on a public road.

Keep in mind this is changing the program code and we don't have a way to calculate those checksums yet so make sure you disable the checksum for the program section which is also included in this version of the ECU definitions
