Does anyone have experience with disabling the fuel correction from the rear o2 sensor?
4-500 samples correction on stock header:

4-500 samples on Gruppe-S header catless:

Looks pretty erratic on the catless header. I tried to zero it out and before my ECU set -3 LTFT. After (with not so much learning) +1.2. Anyone know if there are any disadvantages? I don't know if this could be responsible for months of headache with unstabile LTFT?
The rear sensor is pretty close to the collector. Could it be influenced by the other runners in some kind of reversion?
