-| Just a quick note on MAP(Manifold Absolute Pressure). First, the word "​absolute"​ refers to where zero is placed on the scale. In PSI Absolute, 0 psi is a perfect vacuum and atmospheric pressure is 14.696 psi approx. In PSIg (gauge) atmospheric pressure is zero and a perfect vacuum is -14.696PSIg (equal to 30 inches of mercury, InHg). Kilopascals is the metric version of the absolute measure where a perfect vacuum is zero and atmospheric pressure is 101.325 kPa.\\ \\ The MAP value represents engine load - a higher number represents higher load (more open throttle compared to RPM).\\ \\ For example:\\ Cruising along at 3000rpm on a slight down grade has very low engine load and a lower MAP (kPa) number. If that slight downgrade turns into a steep uphill, you open the throttle to maintain 3000 rpm and the same speed. The MAP (kPa) number starts to climb towards atmospheric pressure 30 InHg (101.3 kPa).\\ \\ Engines require more advance under load at a given rpm and also need more advance as rpm increases at a given load. | +| Just a quick note on MAP(Manifold Absolute Pressure).

-(I think that should be 'less advance under load at given rpm'??)+

 +The point is, MAP readings are the direct air pressure readings and the vacuum gauge reading is the inverse, being the vacuum level reading. In MAP values, the standard atmospheric level is 30, while for the vacuum gauge, 0 is the same level. So MAP value of 20 (out of 30is the equivalent of a vacuum value of 10, because vacuum is reading from 30 to 0. A Low MAP value indicates high vacuum and a High Map value indicates low vacuum - The exact same condition is referenced with inverse scales.
  
 Here's another good reference to understand that the vacuum gauge value and the Manifold Absolute Pressure value are readings taken from opposite ends of the atmospheric pressure range:\\ Here's another good reference to understand that the vacuum gauge value and the Manifold Absolute Pressure value are readings taken from opposite ends of the atmospheric pressure range:\\

-While stock modules from the MoCo are Factory/​Dealer programmable for either 883 or 1200 models, the Screamin'​ Eagle (SE) modules are designed for either 883 -or- 1200 and are not reprogrammable to switch a module from one to the other. However, there are some adjustable SE modules that can be used on either 883 or 1200 models. ​Many of these modules are obsolete and may be hard to find.+While stock modules from the MoCo are Factory/​Dealer programmable for either 883 or 1200 models, the Screamin'​ Eagle (SE) modules are designed for either 883 -or- 1200 and are not reprogrammable to switch a module from one to the other.
