I just read where it isn't possible to bypass it because the way it injects the oil in each cylinder? Saw also where maybe it could be the oil pressure sensor? Agree with you phat about leaving it intact if it is reliable. I haven't hear of any widespread issue with the oil injection failing with etecs, but suppose that is possible.
If you're like me you hate it when a computer tells ya you can't do something that should be really easy! That drives me up the wall! Like my old Honda foreman 450 electric shift. I ended up bypassing the computer because it wouldn't shift. Best thing I ever did!
