    I hope to be going Catless soon. I was under the impression you could disable the 02 sensors with the Predator. How would I go about doing this?

    You may really want to update to 9r02, as the old versions often lead to new P0138/P0158 codes when disabling the rear O2 sensors.

    Thanks

    I will do that. Guess I was lazy and didnt update cause I didnt wanna have to figure out how to drop my fan speeds back down. I am assuming they are still at stock with 9r02.

    I just got these codes and I have been running version 18 since it came out. Can I update my Predator and reload my cmr tune or do I have to get an updated CMR with version 9r02? Or can I send you the tune to get fixed? Thanks.

    Are you going to leave the sensors installed? If so, do you have the option for turning off the sensors and the heaters independently? If yes to all the above you would want to leave the heaters on and turn the sensors off. Otherwise they will foul sooner or later. Best thing would be to turn off everything related to the rear sensors and remove them. Replace them with a bung plug or I think a spark plug fits the hole.

    Removing them is not the best idea....may lead to some voltage codes as we do not have the ability to truly disable the sensors. If you want them out of the exhaust try strapping them up under the car but leave them plugged in.

    Thanks

    Can I modify the program before I load it or do I need to load/modify/reload?

    hmmm, it would be less confusing to some if you referred to "programs" as "tunes". When you say "load the program" lots of people are going to assume (at best) you are talking about the CROM or predator firmware.
