Got a custom tune from B chips and a Diablosport.

When turning off the O2 sensors for an off road H, do i turn off all o2 sensors?

The manual for the tuner says i have 3 options

1 = turn off bank 1 rear sensors
2 = turn off bank 2 rear sensors
3 = turn off all sensors

Thanks in advance !

I would of thought the tune would of had them turned off from the start because you had an O/R pipe

i want to say that you should turn off the rear 02 sensors. i know thats what brenspeed does... someone correct me if im wrong.

Lame.

The tunes i got from Doug were when my car was stock, so im assumming that the tunes still had all 4 O2 sensors on.

I did the diablosport predator software update not too long ago and now the ODB II option is no longer available. Only way to get the O2 sensors turned off is via a revised tune.

Doug is a busy man, so now i gotta sit tight and wait.

Doug says that the rear sensors are not actually turned off in custom tunes.

It's that they're not checked for readiness in order to speed up up processing in the computer. There are other ready checks that are turned off in custom tunes also.

Mr. Ugly

Front sensors definately do have to be working, otherwise you woudn't be able to keep your a/f ratio correct.

I figured as much

I'll just wait for confirmation before screwing around with anything.

Doug's the man !

Sent me the revised tunes in no time at all.
