    Deleting rear o2s?

    Hi, I was wondering if anyone knows how to delete my rear o2s with my diablosport? I think I have deleted the air pump just fine. There are like six different o2 on and off options on the programmer. I sure don't want to turn off my front o2s. I had to turn three things off to delete the air pump. Thanks so much some of you seem very knowledgeable.

    It won't let you turn off the front 02's. I don't have the upgraded unit, but think you need to delete P0137, P0138, P0140, P0141, P0157, P0158, P0160 and P0161 to get them all.

    Hey thanks for the info. I will try deleting them all, and see how it works. This diablosport has come in handy a few times. I have deleted the skip shift, raised the rev limiter, deleted the air pump. Now if I can delete the rear o2s I consider the programmer worth the money. Does anyone know if the programmer actually adds any power?

    Most handhelds give a bit more power over the stock tune, but are generally limited to the tune they are preprogrammed with. They're kind of like a mail order tune for a stock or near stock car. LS1 Edit, HPTuners and a couple others allow the user to tune and retune as many times as you like.

    The rear o2 codes that need turned off are:

    Driver Side Codes:
    P0137 - HO2S Circuit Low Voltage Bank 1 Sensor 2
    P0138 - HO2S Circuit High Voltage Bank 1 Sensor 2
    P0140 - HO2S Circuit Insufficient Activity Bank 1 Sensor 2
    P0141 - HO2S Heater Performance Bank 1 Sensor 2


    Passenger Side Codes:
    P0157 - HO2S Circuit Low Voltage Bank 2 Sensor 2
    P0158 - HO2S Circuit High Voltage Bank 2 Sensor 2
    P0160 - HO2S Circuit Insufficient Activity Bank 2 Sensor 2
    P0161 - HO2S Heater Performance Bank 2 Sensor 2
