Bosch 4.6 Computer Programming
Ok, so here's my dilemma. My rear O2 sensors are shot. I soon plan to upgrade my factory exhaust manifolds for a set of long headers. I plan to leave my catalytic converters in place, however I would like to sometimes be able to unbolt my exhaust and run straight out of my headers without a rear O2 or Catalytic Inefficiency CEL coming on. Is there some way to reprogram the factory computer or some aftermarket computer so that it never checks the rear O2 readings? I know Rover V8s are huge in the engine swap world in the UK, but I seem to have a difficult time finding some parts like these sometimes despite that.

Yes, you can have it reprogrammed to run slightly leaner for a more efficient combustion. I had mine done to run a little leaner and adjust for changed tire size. Got maybe 1mpg improvement according to my UG (probably some hp too but can't prove it). For $120, it'll be worth it in the long run.
