Are you referring to the V2 to V3 update? I already have the V3. My concern is whether I need to bother with the o2 sim update Shiv mentioned in the original post. I don't have catless DP's and don't need the sims. Are the sims active with V3 whether needed or not? Does this mean that the front o2 sensors are ignored right now? Perhaps Shiv can clarify.
