Can we code the DP fix..??

Just wondering if instead of adding JB4 or the BMS DP fix, can we code it out using any of the coding software..??

Thanks!

Not with BMW Group tools. You can edit your bin file in TunerPro to suppress the codes, but the monitors will never achieve readiness.

In terms of not achieving readiness, would that still trigger the CEL to light up..?? I live in Florida so no emissions necessary, just don't want a CEL to be on all the time..

Thanks!

No. If you have the codes disabled in your bin it won't throw a CEL or show a code should you read them out with MHD, etc.

No, once the codes are disabled the CEL will not be lit.

On certain DME versions, there is an option to code off the rear O2s.

However, I have yet to see a car that has had that software loaded on to it.....

As mentioned you will need to basically put a flash tune on your car and edit the fault tables to remove the faults for the rear O2s. You also need to trick the monitors into staying ready in order to pass OBDII emissions testing.

If the readiness monitor is not set to "Ready" you will fail

you would have to flash your DME to suppress the codes.

Is this standard for MHD, on OTS maps that require a cat - less DP, to eliminate the CEL for the rear 02's sensing the wronf readings.. ie no cats...?? Im just curious.
