Well I can give you this much for food.Weather around here jumped up to about 85-95*F and I unplugged my rheostat on the IAT and hooked up the IAT sensor again to play with ideas. My last trip to Boise, ID I pulled 24.5 MPG round trip with hot weather. Then today I had a take trip up to Donnelly, ID weather was cold 44*F and light raining off and on. Well the rain pretty much stopped and still the weather continued to be cold 44-48*F most of the day. My MPG now fell from 24.5 from the Boise trip to 20.5 on today's trip. Cold air tend to degrade MPG's when using the IAT... Time to get my switch built... :whistle:
