Predator won't disable rear O2 sensors? (Moved)

[NavySRT]

I recently had a set of American racing Lt headers and a Magnaflow exhaust installed in my car, and had the car CMR tuned. The results were excellent (409.5WHP/422Tq), until later that night, when my CEL came on. I read codes with Predator: O2 sensor, bank 1, sensor 2 Circuit High Voltage; and O2 sensor, bank 2, sensor 2 Circuit High Voltage. I had kinda expected this with the long tubes, so I went through Predator's menu and found the Rear O2 sensor "Off" option. Installed modified tune, and cleared the codes. Drove car around for about an hour, everything was fine. Two days later, the CEL came on about 30sec after I started the car in the morning, same 2 codes. This has happened 3 times since.
Thought maybe I did something wrong with turning the O2 sensors off, so I did real-time data log for about 5 mins. Both of the rear O2 sensors came up as 0.00volts the entire run.
What am I missing here? how can I get a high voltage trip with the sensors disabled?

Have you contacted Diablo or your tuner?

Not yet, just got car back on Wed. Tuner is out of town until next week.

I'd wait till my tuner could see me.

Since the code thing with long tubes is well documented I'm curious as to your reason for installing them. We already have a nice set of shorties, and our members run 11's N/A with the stock cat back!

Navy - I recently had the same problem. I disabled the o2's with Diablosport and they kept coming back on. Even had CMR tune and the message came back on. I accidentally found something that so far has worked. I recently put my stock tune back in (for winter driving). After having her feel gutless for about a week, I couldn't stand it anymore so I put my perfomance tune back in. The next day the error code came back and I once again turned off the O2 sensors. This was about 2-3 weeks ago and the code has not come back since. Please do not ask me why...I can only say that for whatever reason, once I returned to stock tune and then back again, the disable is now working. Have no idea if it will work for you and wanted to at least share. GL!!!

I was under the impression that the Predator was supposed to be able to remove the codes by disabling the rear O2 sensors. I'm not worried about Emissions testing, so not having the rear sensors work is perfectly fine with me. Everything I read is that the issue I'm having should have been corrected with Diablo Software Update v.9r01, and I'm running 9r08. now I'm wondering if the "fix" for some reason got removed from further updates.

Guess I'll have to give Diablo a call on Monday.

Lethal, Thanks i may have to try that. I've allready tried re-burning the performance tune over itself (modified with O2 sensor disabled), have not tried going to stock in between though.
