I have a K24A2-swapped 02 base auto RSX, TSX'09 intake cam, Injen cold air intake with RSP intake manifold, PLM header, Invidia catback, 05-06 RSX PND ECU, engine harness was repinned to match 05-06 pinout, KTuner rev0.
several days ago I got some error codes caused by bad O2 sensor - P1172 and P2A00. my O2 sensor is just six months old (I bought it brand new when I installed KTuner) and it's strange that it failed so quickly.
I searched for similar problems online and found a related Technical Service Bulletin -
this seems like my issue.Engine Controls - MIL ON/DTC's P1172 or P2A00
07-019 April 12, 2007
Applies To:
2005-06 RSX - ALL
MIL Is On With DTC P1172 or P2A00
SYMPTOM
The MIL is on with PGM-FI DTC P1172 (air fuel sensor [sensor 1] circuit out of range, high) and/or P2A00 (air fuel sensor [sensor 1] circuit range/performance problem) stored.
PROBABLE CAUSE
The air/fuel sensor is damaged by moisture in the exhaust system during engine warm up.
CORRECTIVE ACTION
Update the PGM-FI software with the HDS.
Replace the air/fuel sensor.
NOTE: The PGM-FI software has been changed to delay the operation of the A/F sensor heater when there is a high probability of moisture in the exhaust system.

I guess that I can't go to dealer and check for an update, because this will overwrite my current tune?
If so, my question is - is this fix included in KTuner base code?
thank you.
