ROM Table Discovery & Definitions

Seeing as there isn't a specific thread for this I thought I'd start one rather than tagging it in the middle of the Tactrix threads.

I decided to try WinOLS with some success, however I was wondering if those with IDA could look through and determine if these tables are of any use and what they do.

It seems that WinOLS is fairly good at determining the actual tables and has a go at formulating the expressions, as well as allowing you to view them in a table or 3D format you would be familiar with.

Below are the 10 largest tables that are not yet defined, on my definition at least, for ZA1JA02G. I haven't looked at the A01G but so far the 2 are the same.

@Td-d
@ztan

I'll post the same over on Romraider to see if they can be of any assistance.

I'll have a look in IDA.
Last tried to use WinOLS in 2006...

Unpicking "Alpha 1":

ROM:0004FFFE                 fmov.s  fr0, @r6        ; Floating-point move single precision
We find the x-axis is RPM, y-axis is Throttle, value pulled from the table is stored in FFF89B8C (I don't know what this is yet).

*Thanks, I've updated the code. I figured it would be something like that as the table looks like this:


Seems to have higher numbers in the lower torque areas.

As more are found I'll update the 1st post.

Rather than just picking random tables I have been overlooking the entire ROM, I found these 4 2D tables all in the same portion of the hex dump. They seem to correspond to RPM so I wonder if these are cylinder comp tables of some sort. When viewed as a chart they vary quite a bit.

Code:
    <table name="Alpha 21" storageaddress="11E61C">
      <table type="Y Axis" storageaddress="11E5E0" />
    </table>
    <table name="Alpha 22" storageaddress="11E694">
      <table type="Y Axis" storageaddress="11E658" />
    </table>
    <table name="Alpha 23" storageaddress="11E70C">
      <table type="Y Axis" storageaddress="11E6D0" />
    </table>
    <table name="Alpha 24" storageaddress="11E784">
      <table type="Y Axis" storageaddress="11E748" />
    </table>
Code:
<table type="2D" name="Alpha 21" category="Alpha" storagetype="float" endian="big" sizey="15" userlevel="3">
      <scaling units="Unknown" expression="x" to_byte="x" format="0.00" fineincrement=".01" coarseincrement=".1" />
      <table type="Y Axis" name="Engine Speed" storagetype="float" endian="little" logparam="P8">
        <scaling units="RPM" expression="x" to_byte="x" format="0" fineincrement="50" coarseincrement="100" />
      </table>
          </table>
<table type="2D" name="Alpha 22" category="Alpha" storagetype="float" endian="big" sizey="15" userlevel="3">
      <scaling units="Unknown" expression="x" to_byte="x" format="0.00" fineincrement=".01" coarseincrement=".1" />
      <table type="Y Axis" name="Engine Speed" storagetype="float" endian="little" logparam="P8">
        <scaling units="RPM" expression="x" to_byte="x" format="0" fineincrement="50" coarseincrement="100" />
      </table>
          </table>
<table type="2D" name="Alpha 23" category="Alpha" storagetype="float" endian="big" sizey="15" userlevel="3">

Go to >Options>Setup data types (Alt-D)
An option box will come up with data type rotations that you want included in the data carousel - check "float". Pressing "d" in IDA will change the data type.

To change the line of numbers into an array, press "*" and enter the length of the array.

So this data is available on the CANBUS:

you would need to either sniff the can buss to get the data or get someone to trawl the ecu code to see if its stored in ecu ram addresses.

I suspect what the oft guys did was aquired a device that performes those read functions then sniffed the can buss data requests and coppied requests into oft.

We could do similarly by copying the OFT requests. I don't like that, though. I don't think that's a very ethical way of accomplishing it.

Vishnu, EcuTek have all got their parameters by either disassembling the ROM or sniffing the CAN bus. Ethical would be buying the info from Toyota or Subaru, but they aren't selling.

I had a look at this briefly a couple of years ago, sniffing Techstream requests on CAN:

That thread actually had this a few posts from where you linked in:
