Hi people.
A few more qns:

i/   Is methanol bad for EFI system components (pump/hoses/injectors)?
     I heard that it can be corrosive in this situation.

ii/  Does the output of an oxygen sensor reflect the air-fuel mixture
     being correct FOR ALL FUELS? IE in a petrol engine at stoic
     (14.7:1) the voltage is in the 'transition zone' of ~0.2-0.7v

     Will this voltage 'transition zone' hold true for any fuel type
     at a stochiometric (ideal) air - fuel ratio?

iii/ Can Nitrous solenoids be 'dithered' by duty cycle (like a lot of
     idle air valves are)? The idea here is to make the onset of 
     nitrous delivery more smooth. (Assume the amount of fuel put into
     the engine is increased proportional to the nitrous amount)

Thanks,
Craig.
