That's good to know about the robustness of the ECUs. I agree that I should be checking the parameters of various sensors and whatnot, if only I had a BHW or even a BEW manual. I assume the CCV pigtail is the shorter of the two. I have all the bits n' bobs I've removed from the engine, and can return everything to stock...as a last resort. I removed those items as much for accessibility as the desire to eliminate unsightly and unwanted weight. I really like the longitudinal arrangement for its relative ease of service as opposed to transverse, and I like furthering that goal as much as possible. Moving the N75 is probably my favorite mod.
