Were you looking for a definition of MAP? aka Manifold Absolute Pressure?
This page is about ECU maps.
There is no standard for the formats with which ECUs store the maps? that they use to control the engine, so in order for RomRaider to work for a given ECU, someone has to create an ECU definition which tells RomRaider which maps are available for editing and where they are stoed in the ECU’s memory.
Detecting and defining maps is a time-consuming process which typically involves many hours spent using CPU documentation and a tool such as IDA Pro to disassemble a ROM from the ECU in question.
