Default O2 sensor ******** fix - 08-29-2015, 12:53 AM

i know many guys have had the problem of O2 codes after fitting dp's especially IJEOS guys but not limited to them i have had success with 90% of the cars without the need to replace O2 sensors only 10% of the time was there actual failure of the O2 sensor so follow these simple steps and save yourself money

you need a working inpa connect to your car using dcan cable
select e90 series
go to engine and select msd80
select tab at bottom of screen delete adaptations
find oxygen sensor and hit delete adaptation tab
quite simple

It re adapts all the o2 sensors
Give it a shot
If this doesn't work replace the sensor
