My04 WRX (SADM) Unknown rom

There is NO change to the definitions with 0.5.0b RomRaider update. It was a software update only. Like I said, this ROM has already been added to the list for the next def update and it will be June or July when those are released. I will update this thread when the new RomRaider defs are available.

Thanks merchgod!

adding definition for A4RM100F is easy as it is exactly the same as A4RM200K

Make sure romraider is not running.
Open ecu_defs.xml file with a text editor
search for "32BITBASE" text

Code:

<!--insert following lines-->
 <rom base="A4RM200K">
  <romid>
   <xmlid>A4RM100F</xmlid>
   <internalidaddress>200</internalidaddress>
   <internalidstring>A4RM100F</internalidstring>
   <ecuid>2EA4584005</ecuid>
   <year>03</year>
   <market>SA</market>
  </romid>

<!--before these lines-->
<rom>
  <romid>
   <xmlid>32BITBASE</xmlid>
   <market>USDM</market>
   <make>Subaru</make>
   <model>Impreza</model>
   <submodel>STi</submodel>
   <transmission>MT</transmission>
   <filesize>512kb</filesize>
   <memmodel>SH7055</memmodel>
   <flashmethod>sti04</flashmethod>
  </romid>
 </rom>   

save ecu_defs.xml, close, open romraider and your ROM

have fun

You cannot do this! This will screw up your ROM for sure. The switch (CEL) definitions are different between these two roms and doing what tinywrex suggests will cause a portion of the A4RM100F ROM to get overwritten (that is bad). This is because of the way RomRaider deals with the off switch values. This is why I do not suggest users randomly inheriting from other roms. This may work with out any of the switch defs, but I haven't looked at it yet (I do new roms last during the ECU/logger def update process). The process to add roms for ecu/logger defs is to check every table/variable in IDA not make guesses.

Oh you bet you can do this!

do what i posted above and you can tune any table for A4RM100F except the CELs

people will be happy until you finish the CELs (shouldnt take more than 5 minutes) :mrgreen:

No you can't. RomRaider overwrites the off values for switch tables to the rom when you save even if you don't change anything. Even if you did this in Ecuflash, which does not have this behavior, what would do you think would happen if the user attempted to disable a CEL (which you didn't mention in your original solution)? And it is not just CELs, but the TGV fixes and force pass readiness tests that are different between these two roms.

Assuming that the normal table offsets are all the same (I haven't checked this), you would need to copy the A4RM200K defs, replace with A4RM100F and remove all switch tables (cel, tgv fixes, etc.). That would work (again, assuming all the table offsets are correct) but not something the typical user should be messing with. Which is why I don't even bother with giving user temporary solutions. I don't even look at the new submitted roms until I'm done with everything else for ECU defs (new tables, fixes, etc.) to make sure I have a complete correction solution (and it is also faster this way). I'm not trying to be dick here, least of all to you tinywrex, just trying to make sure users don't run into any problems. There is a method to my madness.

EDIT: Doing a quick look, some of the normal table offsets are not the same either (ex. Manifold Pressure Sensor Multiplier A-D and Manifold Pressure Sensor Offset A-D. So just removing the switches is not going to 100% correct either). Wait for the official defs!

One owner said He got another 2003 WRX rom and He uploaded the rom over the original ECU, and He was able to work the ECU with this new rom...

I haven´t done this already but his car runs...

Sorry for bother, but does anyone knows if there's any new release date for this def?

Regards

Hi,

First thanks for the Def...

Just a quick question, I have been able to download the data from my car as I previous did. However when I try to open on the again the MAP on the ECUFlash. I'm not able to upload the data to the car since the def was not release to Ecuflash.

I'm starting to creating the DEF for the ECUFlash, but since I haven't done this in the past, I just would like to double check, I have copied the DEF from romraider but I stuck in the two points:

<memmodel>68HC16Y5</memmodel>
<flashmethod>wrx02</flashmethod>

I have copied this one from A4RM200K those two lines.

Could someone give me a hand with this?
Attached is the DEF for ECUflash that I have created.

Thanks
Regards
Felipe

you cannot copy the RomRaider defs to Ecuflash, although you don't need table defs to flash the ROM with Ecuflash. The Ecuflash version defs will be out soon, maybe today.
