You might want to re-think this one :-) How much does dry ice cost (not just money, but in energy) vs the amount of gas you expect to save? How long will the dry ice last in the summer? How much extra gas will you burn driving to wherever you plan to get the dry ice? How often will you have to stop and add a chunk or two to the air intake?

If all you want is to fool the ECU, why not just put a small microprocessor in the circuit between it and the sensor(s), and map whatever response you want?

Really, you should have waited until April 1st to post this one :-)
