... this is a big indicator IMO ... If you can see the resistance of the
switches change at the Idle and WOT switch, but do not see the ECU react to
them in changing the duty cycle that is a problem.

IME the OXS is actually pretty easy to get at with the headlight removed and
the lower part of the airbox out ... which is something I can do on my car
in a few minutes ... perhaps its because of the Cibies ... but based on what
you are now seeing, it sure seems to me that replacing the OXS would be a
waste of time (and perhaps money) at the current stage.
