Fuel Pump Duty High and Medium Tables

I haven't searched them out in the 16bit roms unfortunately...

Dang.... Oh well guess ill bypass the FPC till I figure it out . Supposedly the addresses are AA6A03B0 for cruise and 556A03B0 is idle for 16 bit. Gathered from another post, but I don't really know how to look in the rom for the hex address. Like I said big learning curve and this is my daily driver. So I may juyst jump it till I figure it out .

Oh - those duty cycles I can find for you, no problem. As soon as I'm on my PC I can pull those out.

d9eD - idle

d9cb - cruise

Awesome thanks . Ill try it as soon as i get home. Thanks a million!!

Ok got it working buuut.... Idle fuel pump duty cycle is at 63.56 . Isnt it suppose to be 33 ? Cruise is at 66.67 which i believe is right. So im thinking the address for cruise is wrong. Any ideas? Thanks again.

Just wanted to update w/ the help of td-d. Here are the locations for AE5IB00V if anyone needs them.

Code:

ROM:000AB038                 .data.l 0

Here's the code as well if needed:

Code:

<scaling name="IDC" units="Injector Duty Cycle" toexpr="x*0.7371358727094787" frexpr="x/0.7371358727094787" format="%.2f" min="0" max="255" inc="1" storagetype="float" endian="big"/>
   <scaling name="Pressure (bar)" units="units" toexpr="x/750" frexpr="x*750" format="%.2f" min="0" max="255" inc="1" storagetype="float" endian="big"/>


   <table name="Fuel Pump Duty High Injector Duty Cycle" address="D60DC" type="3D" level="1" scaling="IDC">
      <table name="Battery Voltage" address="D60C8" type="X Axis" elements="2" scaling="rawecuvalue"/>
      <table name="Manifold Relative Pressure" address="D60D0" type="Y Axis" elements="3" scaling="Pressure (bar)"/>
   </table>

<table name="Fuel Pump Duty Medium Injector Duty Cycle" address="D6104" type="3D" level="1" scaling="IDC">
      <table name="Battery Voltage" address="D60F4" type="X Axis" elements="2" scaling="rawecuvalue"/>
      <table name="Manifold Relative Pressure" address="D60FC" type="Y Axis" elements="2" scaling="Pressure (bar)"/>
   </table>

I had trouble since I was using standard scaling. Change your pressure scaling to whatever's used in your 32bitbase.

Do you by any chance have the location addresses for A2WC522N?

Old thread revival, any chance of getting these tables for A2ZJ710J Please?

A2WC522N and A2WC522S - though I admit I'm not 100% certain I've got this right.
It uses a different scaling than in the other examples. Are the values 13 and 39 typical for the cells inside the tables?

Code:

   <scaling name="IDC" units="Injector Duty Cycle" toexpr="x*0.01" frexpr="x/0.01" format="%.2f" min="0" max="255" inc="1" storagetype="uint16" endian="big"/>
   <scaling name="Pressure (bar)" units="units" toexpr="x/750" frexpr="x*750" format="%.2f" min="0" max="255" inc="1" storagetype="float" endian="big"/>


   <table name="Fuel Pump Duty High Injector Duty Cycle" category="Fueling - Pump" address="CA88C" type="3D" level="1" scaling="IDC">
      <table name="Battery Voltage" address="CA87C" type="X Axis" elements="2" scaling="rawecuvalue"/>
      <table name="Manifold Relative Pressure" address="CA884" type="Y Axis" elements="2" scaling="Pressure (bar)"/>
   </table>

   <table name="Fuel Pump Duty Medium Injector Duty Cycle" category="Fueling - Pump" address="CA8A4" type="3D" level="1" scaling="IDC">
      <table name="Battery Voltage" address="CA894" type="X Axis" elements="2" scaling="rawecuvalue"/>
      <table name="Manifold Relative Pressure" address="CA89C" type="Y Axis" elements="2" scaling="Pressure (bar)"/>
   </table>

If what NSFW found is correct, here they are on the '06 Legacy (A2WF200C and related):

Code:

<scaling name="IDC" units="Injector Duty Cycle" toexpr="x*0.01" frexpr="x/0.01" format="%.2f" min="0" max="255" inc="1" storagetype="uint16" endian="big"/>
   <scaling name="Pressure (bar)" units="units" toexpr="x/750" frexpr="x*750" format="%.2f" min="0" max="255" inc="1" storagetype="float" endian="big"/>


   <table name="Fuel Pump Duty High Injector Duty Cycle" category="Fueling - Pump" address="CA770" type="3D" level="1" scaling="IDC">
      <table name="Battery Voltage" address="CA760" type="X Axis" elements="2" scaling="rawecuvalue"/>
      <table name="Manifold Relative Pressure" address="CA768" type="Y Axis" elements="2" scaling="Pressure (bar)"/>
   </table>

   <table name="Fuel Pump Duty Medium Injector Duty Cycle" category="Fueling - Pump" address="CA788" type="3D" level="1" scaling="IDC">
      <table name="Battery Voltage" address="CA778" type="X Axis" elements="2" scaling="rawecuvalue"/>
      <table name="Manifold Relative Pressure" address="CA780" type="Y Axis" elements="2" scaling="Pressure (bar)"/>
   </table>

Thanks Merp, you rock!

In return, I endeavor to dig these out for more roms

Could you find the fuel pump switch points for A4TF800F?

With larger injectors the fuel pump switches far too late since its IDC dependent, causing AFRs to lean out at unfavorable times and then slam rich when it finally does go 100%.
