For a2wd012b, which is sub of a2wd010b is it:

696cc for 02 comp

and that's leaves 6cd50 and 6ce84 being either af1 learning or af3 adder as this ecu is earlier sti type that doesn't have af3 limits?

There was fourth -0.5/0.5 at 696e5 too.

thanks.

Did you ever figure out the other addresses for A2WD012B?

I'm using these

0.5/-0.5 values (3F 00 00 00 BF 00 00 00) found in two locations, also found the adders and the TPS based tables:

Code:

   <table name="AF 3 Correction Limits" address="2B74C"></table>
   <table name="AF 3 Learning Limits" address="29010"></table>

   <table name="AF 3 Correction Adder (Increase)" address="65750"></table>
   <table name="AF 3 Correction Adder (Decrease)" address="6574C"></table>

   <table name="AF 3 Correction Adder (Increase) B" address="66410">
      <table name="TPS Opening %" address="663EC"/>
    </table>
    <table name="AF 3 Correction Adder (Decrease) B" address="66448">
      <table name="TPS Opening %" address="66424"/>
    </table>

Bit of a necro, but I am looking for the address for a 2014 USDM WRX. AE5Q100L. I was going to try and find it myself, but purchasing IDA Pro for one thing seemed to be a little bit if a stretch if someone had access to it already.

Thank you in advance.

I simply cut the wires from to the rear O2 sensors and disabled all errors in ROM for it.
I assumed that since there is no signal from the sensor, the computer wouldn't take it into account when calculating the mixture.
I didn't notice any negative effects.
But my catalytic converter left a chat a long time ago; it doesn't care.
