Default Dead ecu after welding on header

2005 Forester XT MT

I had a muffler shop cutting out flex pipes on my header. When I get the car back it has a p0032 code after clearing and even if o2 is unplugged. So how do I figure out if itís the sensor or ecu. I lean towards ecu, Iíll go into romraider and check the o2 data, try a reflash and delete the p0032 so I at least get my boost control back. Iím running openloop all the time showing 13.4:1 off boost, so no danger as of yet.

Its not the ECU, they probably damaged the sensor or the wiring for the sensor. Ive done weld repairs on multiple dozens of cars and have never ever had a single electrical issue with one.

Iíll start with o2, nothing wrong with a fresh o2 sensor either way. The cell is on but it hasnít disabled the boost controller. In boost is the only place itís acting normal. Only thing itís doing is running a point rich where it would normally be in CL.
