Can you please check addresses for Overrun Fueling RPM Resume Threshold
I see negative RPM in the table.

Thanks a lot, td-d
Will change to:

<table name="Overrun Fueling RPM Resume Threshold" address="C8C8C" type="2D" level="1" scaling="RPM">
<table name="X" address="C7A24" type="X Axis" elements="16" scaling="DegreesF"/>
</table>

<table name="Overrun Enrich RPM Delta Activation" address="C7920" type="1D" level="1" scaling="rawecuvalue"/>

<table name="Overrun initial injector enrichment (pulsewidth)" address="C7924" type="1D" level="1" scaling="ms"/>

<table name="Overrun Fueling Cut Counter RPM Threshold" address="C796C" type="2D"
level="1" scaling="RPM">
<table name="RPM" type="Static X Axis" elements="3">
<data>Low</data>
<data>Med</data>

C8C8C is definetly correct:

Code:

ROM:000C8C8C                                         ; = 2.4e3

ROM:000C8CA2                 .data.w h'1400          ; = 1.0e3
ROM:000C8CA4                 .data.w h'1200          ; = 9.0e2
ROM:000C8CA6                 .data.w h'1200          ; = 9.0e2
ROM:000C8CA8                 .data.w h'1200          ; = 9.0e2
ROM:000C8CAA                 .data.w h'1200          ; = 9.0e2

Right click the table in Ecuflash, and make sure all the scalings are correct.

The definition seems to be correct, but RPM is negative.

Ok, I can see what the issue is - you didn't copy the template exactly from Github, so the RPM scaling (which is uint16) is incorrect (scaling = RPM is float).

You could have saved yourself all this pain by just checking the Alpha branch on the Github repository - overrun (and a whole bunch more) is already defined for this rom.

Hi
Do you know the address for EDM 2001 WRX A4SE900D

PZEV Outback 2005 ROM

Probably some another overrun logic.
I failed to trace the usage of the maps.

awsome thanks!

Everything seems to be decent except for the ECT on the 2D table. Any Ideas?

Here is my code:

Code:

   <scaling name="overrun" 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" address="C7384" type="2D" level="1" scaling="overrun">
      <table name="Engine Coolant Temperature" address="C66D0" type="X Axis" elements="16" scaling="CoolantTemp(DegreesF)"/>
   </table>

Its interesting that the pulse width is 2.8 m/s.

Try DegreesF for the scaling.

It actually worked when I put in DegreesC but not for DegreesF.

Are you running the latest 32bitbase from Github?

I don't believe so.

These tables work though. Fixed my almost stall situation from raising my idle for larger injectors. Also fixed my extremely rich condition when letting off the gas. Probably because mine was set to 2.8ms from the factory. I set it to 1.0ms and seems to be working great.
