OK, so it goes between the intak air temp sensor and the ECU. WHile I'm sure it could adjust for some conditions I can't see it being enough to alter the whole air fuel mixture other than in a general way since it isn't tied to the throttle position or RPM sensors. Just the intake air temp. So any change it makes will be a generic wide band trend rather than point by point alterations to the maps.
Get a Power Commander. It uses a series of maps for various RPM and TPS sensings and alters each of the multiple maps for various throttle settings and RPMs to pin point the fuel changes needed to get the smoothest power over the whole range of possible options rather than just using this one bit of IAT stuff to add a general correction overall that likely won't be right for more than one or two points out of the literally thousands of points in the series of maps that a Power Commander deals with.
