you are pretty extensive and your list of modifications. Didn't see anything about a Turbo XS Utec for tuning. I think you may have posted in the wrong forum if you dont already have it under the passenger footwell.

If this is just for the ecu reading not ready, it could be two things. 1) you haven't driven as many cycles and miles as is needed to pass onboard diagnostics. 2) the prevoius owner used a MIL resistor inline with the rear O2 sensor and is preventing diagnostics to be completed.

if neither, then I would try a spark plug anti-fouler adapter between the rear O2 and the pipe.
