RomRaider

Muddling my way around I think I found it.
per the previously defined 16bit defs


Idle duty i'm getting 33.33 and cruise duty i'm getting 66.67

I would love to try this out on my LGT.

ECU ID: 52125A5007
Internal ID: A2TB000N

I have similar symptoms since I got a rotated kit.

Here you go (in red):

ROM:00045CAC flt_45CAC: .float 66.699997 ; DATA XREF: sub_45BEA+5Ao
ROM:00045CB0 flt_45CB0: .float 33.299999 ; DATA XREF: sub_45BEA+72o

Awesome! Thanks. I will dig in on this tonight and see if I can report back after I check it out.

Thanks td-d!

I am struggling a little here. I am looking to update my ecu's xml def in ecuflash so I can edit these parameters. But the xml snippet only calls for one address. Which address should that be for my ecu?

This is an example of the XML snippet I added. Which I added directly to my ecu's xml file.

<table name="Fuel Pump Duty" storageaddress="45CB0" />
<table type="2D" name="Fuel Pump Duty" category="Fueling - Injectors" storagetype="float" endian="little" sizey="2" userlevel="2">
<scaling units="Duty %" fineincrement="1" coarseincrement="5" />
<table name="Fuel Pump Duty" type="Static Y Axis" sizey="2">
<data>Medium</data>
<data>Low</data>
</table>
<description>The ECU will set fuel pump duty cycle to 0%, 100%, or one of these two values.</description>
</table>

I tried these three values for storageaddress, and none of them appear to be appropriate:
45CAC
45CB0
45BEA

The new parameter shows up in ecuflash, but when I click to edit the map it does not have any values in the Medium, and Low categories. They are simply blank.

I assume I am missing something here. Any help would be greatly appreciated.

Thank you!

Use the updated 32BITBASE from this post.
Then just add this line to the XML file that EcuFlash uses for your ROM.

Yep that did the trick. Thanks!

After setting the pump duty to 70/100 I took an initial drive. The response in the 2000-3500 range with light to moderate throttle is much more steady. The stumble appears to be mostly gone. I think I have some other issues contributing to odd low load low rpm hesitation. That situation aside, this one change has made the car more smooth at cruising speeds and during mild acceleration.

My mechanical setup is:
2008 Legacy GT
Perrin 30R kit for an STi.
Custom Air to Water intercooler.
850cc injectors (Forget which, scaled to about 700)
Walbro 255lph

Thanks again for the help!

Beat me to it, Dale. Thanks for that - glad you got it sorted.

Can someone help me with an ADM 06 WRX A8DH200O address please?

Done

Love your work

Could anyone please help in finding the table for JDM08STI - AZ1G300F?

Thanks in advance.
