Imperial units don't lend themselves well to engine management, or much of anything else really.

MAP stands for Manifold Absolute Pressure, meaning pressure relative to absolute zero. The problem lies in the fact that we have to account for atmospheric pressure, which is not constant. Changes in weather and altitude affect atmospheric pressure, so it's not a constant point. Boost is considered anything above atmospheric pressure, so we would have to hit a moving target for the "zero" point, and everything below that would be considered vacuum. If you've ever owned a boost gauge with imperial units, you'll see that vacuum is traditionally measured in inches of mercury, and boost is measured in pounds per square inch, which is messy.

The easy and clean way to do this is to use metric units on an absolute scale, and get used to the fact that 100 kPa is roughly atmospheric pressure, and 100kPa is equal to 14.5 PSI. At first you'll be doing math in your head a lot, but once you get used to it you won't want to go back.

The android Blue tooth app has the option to display imperial units!
