I tried to search, but had no luck. How do I turn off my rear O2 sensors? I am about to get an OR-X and would rather turn them off than have the SES light on or get MIL-Eliminators for it. I have a DiabloSport Predator and have the 93 octane tune loaded. Anyone have some info? Thanks.

Is it not in the menu? If not, I think I read somewhere at one point depending on what revision your predator is it may have that functionality removed by Diablosport.

I didn't see it...what section is it under? I will have to check it out again in the morning.

If your Predator has that function it will be under the OBD2 menu:

Just the guy I was hoping would chime in...I will post in the morning to let ya know if I got it to work. Thanks.

I don't even find the OBD2 Menu anywhere on it...I've had my Predator since January 08. Does it need an update or what?

cliffyk

It probably needs to be "downdated". It was about that time that the EPA went around rattling cages and the major handheld manufacturers dropped the ability to diable the EGR and rear O2 sensors. That was when the supply of commercial MIL eliminators started to go away too.

MIL eliminators have come back a bit, IDK whether Predator has reinstated the OBD2 menu, or if you can indeed "downgrade" the firmware???

I tried the MIL eliminators and that didn't work. Made my own and bought some - neither did the trick. Bought an SCT 3015 tuner and it allowed me to disable the sensors.

Yeah Cliffy, I've thought about making some using your article on your site. Maybe I will just live with the dummy light...Or upgrade to a better tuner. I wish I would've bought the SCT when I got mine, I always have. I will figure this out though. Thanks guys.
