I would have thought that was true as well, but I'm not convinced now. Mike (Qatar11) and I have been discussing it some and I really don't see anything the engine is using them for that I would be able to tune around. The fact that it doesn't even trigger a CEL seems a bit odd to me. Thats the whole point of the CEL, to tell the user when one of the sensors is messed up. If it needed them, why wouldn't it say so? I don't suggest anyone else do this, but I'm going to do some more testing on this subject and see what I come up with. I want to have a definitive answer before I go FI. |
