Two observations about the IAT sensor mod:
1. The computer can't "learn" that you've altered the IAT signal because it has no baseline to refer to, the temp always varies. It just acepts the temp as OK.
2. With a colder IAT signal the computer does two lthings. It advances the timing and richens the mixture. When it does this it gets feedback from other sensors. The nock sensor will tell it if the timing is too far advanced and the O2 sensor will tell it if the mixture is too rich. In either case the computer will adjust settings for best motor operation. Final result: a correct fuel mixture with advanced timing, the prescription for better MPG
