all you have to do is disable the o2 heater in uber and you can run the p28 with no o2 cel and no wire swapping. just a temporary fix though, you would have to rewire for the 4 wire in order to run proper closed loop with the p28.

 

i see in all the pictures that r52 is empty am i supposed to remove it. i cant find anything on that. ive resoldered all the pins three times so im sure i didnt get a cold joint. the burning of the chip is probly where i am ------- up or a bad chip.
