how do you turn the o2 feedback off on a HCR32 RB20DET with a type 2 board?

Either turn off o2 in fuel map cells by selecting them and pressing "O" or increase o2 feedback temp to 200deg.
Its all in the documentation available from the documentation area.

thanks nanook , just as handy to put up a post and it will be there for the next person with the same question.

the sr20det nistune has a feedback switch just didn't know if i had missed it, i work on a lot of different ecu's hard to remember ever bit of every manual i've read

yeah the Type 3/4 boards have the feedback switch which has options for O2 sensor and knock sensor

Type 1/2 has feedback switch only on some ECUs, but has the O2 feedback temperature to use otherwise (set to maximum to disable O2)
