2. MAP sensor - Wikipedia

   en.wikipedia.org/wiki/MAP_sensor

   This is commonly referred to as gauge pressure. Boost pressure is relative to absolute pressure - as one increases or decreases, so does the other. It is a one-to-one relationship with an offset of -100 kPa for boost pressure. Thus, a MAP sensor will always read 100 kPa more than a boost sensor measuring the same conditions.

3. Trionic - Wikipedia

   en.wikipedia.org/wiki/Trionic

   The Trionic 5.2 and 5.5 systems utilized the manifold absolute pressure (MAP) sensor and the intake air charge temperature sensor to calculate the fuel injection curves, while the Trionic 7 and 8 systems are mass air flow type. Both systems have substantial differences that prevent utilization of components between the two.

4. MAFless Tuning - Wikipedia

   en.wikipedia.org/wiki/MAFless_Tuning

   On vehicles so equipped, this alternative involves the use of a manifold absolute pressure, or MAP, sensor. The MAP sensor measures pressure in the engine's inlet manifold. When coupled with data regarding the engine's revolutions per minute, or RPM, and a table of volumetric efficiency over the operating range of the engine, the MAP sensor can ...

6. Boost gauge - Wikipedia

   en.wikipedia.org/wiki/Boost_gauge

   Boost gauge on a Ford Focus RS (left) 30 psi Boost gauge Top: Turbo/APC boost gauge in a Saab 900. A boost gauge [1] is a pressure gauge that indicates manifold air pressure or turbocharger or supercharger boost pressure [2] in an internal combustion engine. They are commonly mounted on the dashboard, on the driver's side pillar, or in a radio ...

7. OBD-II PIDs - Wikipedia

   en.wikipedia.org/wiki/OBD-II_PIDs

   OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool.. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.

8. Boost controller - Wikipedia

   en.wikipedia.org/wiki/Boost_controller

   A 3-port solenoid-type boost controller A 4-port solenoid-type boost controller (used for a dual-port wastegate). The purpose of a boost controller is to reduce the boost pressure seen by the wastegate's reference port, in order to trick the wastegate into allowing higher boost pressures than it was designed for.

9. Jaguar AJ6 engine - Wikipedia

   en.wikipedia.org/wiki/Jaguar_AJ6_engine

   The Lucas fuel injection system on the 3.6 L (3,590 cc) AJ6 engines in these early XJ-S cars sensed engine load using a Manifold Absolute Pressure (MAP) sensor just like the V12 cars from the same era. Later 3.6 L (3,590 cc) AJ6 engines as used in the 1986–1989 XJ40 cars had a crank-sensor type of ignition system with a bare distributor that ...
