In the interest of investigating WAI, I captured some numbers this week on five day drive to work trip. Idle Fuel Flow only, No AC.
I was lucky to have a few days of cold engine/warm IAT, a few days of Cold engine/cold IAT, and a day of warm engine/cold IAT. Some ranges, I just couldn't arrange. I tried to get all the readings at the top of the temp ranges in each set. They were very reproducable. With spring approaching, I'm hoping to fill in the blanks some. I see why the block heaters are popular.
I guess it's not shocking the linearity of it all. I was pleased to see the >185°°F FWT and 115°F IAT. Makes me want to make a adjustable WAI. Getting dynamic, non-idling numbers are near impossible. I'm hoping there will be some coupling with fuel flow up to 1.5-2.0 gpm or so.
