Web18. avg 2011. · I am confused on this issue. That is nothing new. On the fuel map in either tuner studioor MEgatune, vacuum and KPA have an inverse relationship. 20 inches of HG on my gauge sets the pointer into the lowest cell on the fuel map. This is somewhere around 30 KPA. As the vacuum reading approaches 0, the KPA scale goes up, and reaches 100. WebConvert pressure values from kPa units to psi pressure units using the following method: 1 psi = 6894.76 Pascals (Pa) 1 kPa = 1000 Pascals (Pa) psi value x 6894.76 Pa = kPa value x 1000 Pa.

Web05. jun 2024. · What is a MAP sensor supposed to read? With the engine not running and the key on, the MAP sensor should read around 28-inHg. When the engine is started and idling, the vacuum of the engine should reduce atmospheric barometric pressure by 20-inHg. The reading on the scan tool scan tool should be approximately 8- to 9-inHg. WebThe intake manifold vacuum reduces the original barometric pressure by around 9.7 PSI (20 inHg), so the MAP sensor reading drops to about 5 PSI (10.1 inHg). A running engine with a closed throttle creates negative pressure, while the closing and opening of the throttle body valves create positive pressure (though it’s still lower than ... bluff creek christian church greenwood in
