is anyone able to verify an address for me or tell me how i can try? i hooked the 5v out from my wideband up to my ecu to log via evoscan now i get the SES light for P0139 despite having changed this to 0x0:
<table name="DTC P0139 Disable 0x1 -> 0x0 Oxygen Sensor Circuit Slow Response (Bank1, Sensor2)" category="Misc" address="503b8" type="1D" scaling="Hex8"/>
note: '12 gsr, rom id 5801005, no rear o2 with bit.1 disabled.
<table name="DTC P0139 Disable 0x1 -> 0x0 Oxygen Sensor Circuit Slow Response (Bank1, Sensor2)" category="Misc" address="503b8" type="1D" scaling="Hex8"/>
note: '12 gsr, rom id 5801005, no rear o2 with bit.1 disabled.

That address is correct, but that may not stop you from getting CEL's from hooking in the wideband's output. I don't know if anyone has done that yet with the newer roms.

here is the new code for DTC P0139 as well as DTC P0140 for 58010005.
* note, i no longer have DTC P0140 disabled due to installing the wideband. i went from no activity (P0140) to having irregular response with the wideband (P0139).
Code:
<table name="DTC P0139 Disable 0x1 -> 0x0 Oxygen Sensor Circuit Slow Response (Bank1, Sensor2)" category="Misc" address="503bb" type="1D" scaling="Hex8"/> <table name="DTC P0140 Disable 1500 -> 8000 Oxygen Sensor No Activity (Bank1, Sensor2)" category="Misc" address="539ce" type="1D" scaling="RPMStatLimit"/>
thanks to rich indeed.

Haha, that's my android tablet running an app called torque pro. Uses a obd2 bluetooth adapter.
I'll post a pic of the other page with the gauges.
found a pic when it was installed in my old car. pre evo, now i love that it's my boost gauge.

EDIT: i just noticed your signature. you have a lot of work done so this may not even get close to applying to your situation but:
p0300 is multiple misfire. did you do anything to change the ignition system?
p0219 is engine over speed. was there a mis shift/over rev?
the ecu presenting both of those codes in combination would lead me to believe the motor over-revved (p0219) and there could be valve damage (presented as misfiring in p0300).
