O2 sensor location on 180 ? headers tuning issues

Hi, As mentioned in a previous post I have a LS2 in a Porsche Porsche Boxster. Unfortunalty itis using an E40 ECM for an automatic vehicle which I have not been able to change yet. I also Built my own 180? headers and namaged to adapt the Injector Bank selection so the incectors get the correct signal from the O2 sensors.

I am still having problems that the LTFT and STFT somtimes are quite differt between the banks. My O2 sensors are quite far away from the engine. I would say about at least 1,5 foot after the collectors.

I tried adjusting the the O2 sensors, by lowering the proportional aorflow mode by x 0.9 and increasing the delay by 1.2 , as I had read in a thread here, and got the following results.

Could someone look at the screenshots and tell me if that looks right? What wonders me is that the O2 sensors are almost syncrone sometimes and somtimes very differtent, especially at lower RPM. Also, the incector pulses seems to be slightly different most of the time as are the Fuel trims.

I know my speed sensor is not working yet, and hope this has no effect on all of this .

Does anyone have an Idea what to do? Attachment 132915 Attachment 132916 Attachment 132917 Attachment 132918 Attachment 132919
