Im confused also , I have changed my wideband sensor (moved from bosh to NTK ) and I got the same reading . BTW my S is f20 DBW not F22 , maybe that is why .
I'm using NGK AFX powerdex , and I placed my sensor in my test pipe .

That could be the reason why. I'm not sure if euro s2k (f20 dbw) uses the same sensor as US model f22 dbw...That can explain why the A/F correction is more accurate than the A/F reading. You guys might be using the same sensor as the civic. I'm not sure.

All I know is that A/F reading from what Gernby did with his car show that A/F is more accurate than A/F corr reading.

I'm looking at doing the e-tuning soon as well. I'm currently running the injen calibration and not the toda. I have for mod wise is injen intake, 70 mm test pipe, and 70 mm exhaust. The only reason why I haven't run the toda map is because we have shitty 91 octane over here. I would feel more at ease if I had 93 to run a more aggressive timing map.

 

You can try out the toda tune, the ecu will retard timing for the 91 octain....if your getting alot of knocks or feel a lose in power from your last tune i would deff switch back to your old one....but it wouldnt hurt to try it out

 

I started my Evan's E-Tune recently, and just got time to upload his first calibration last night. WOW is all I can say, what an improvement over the Toda tune... without any actual in depth tuning at all, just the base calibration he gave me, the engine is way smoother, the VTEC engagement is much less noticeable, and I'm feeling a very prominent power increase above 6000 especially. My AFR is in the high 11's and 12's across the board now so there is still much tuning to be done, I can't wait

 

14.7-15.5 for part throttle & 12.8-13.2 for wide open throttle (n/a).
