op-amps

I have been told that the following tip can be used at the track
to realize some real performance gains (2/10 -3/10 quicker and .3 to .4
mph faster in the 1/4 mile.  Disconnect the IAT (intake air temperature)
sensor and plug in a xxk ohm resistor to fool the computer staying in
"warm up" mode.  Can an op-amp be used to achieve the same result?

Another tip was to put a 2nd water temperature sensor in the windshield
fluid container and wire this to a switch in conjunction with the normal
water temperature wiring.  Could an op-amp be used instead of this set up?

Thanks for any opinions.
