Hi all,

I've got a 1998 528i with an S52 engine swapped in. It retains all factory emissions equipment other than secondary air. I need to pass emissions which allows for two monitors to be left unset. Currently it does not set Oxygen sensor monitor, Evap, Cat, and obviously SAI. I would like to reprogram the O2 sensor monitoring & catalyst monitoring back into the system so it will set those respective monitors.

What is the best software set and method to do this? I have the appropriate cables to flash myself or to have someone do it remotely but I am also open to sending the DME to whomever can do this and paying them for their services.

Thank you!
