All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

'Engine mapping' is one of those very loose industry terms. It can be both a noun or a verb!

Typically, in noun form, it refers to the data grid which displays fuel injection volume, ignition timing or any number of correction factors influenced by the suite of engine and chassis sensors. This is a very loose description because 'engine map' can refer to almost any electronically configurable aspect of the engine!

I expect the precise terminology of 'mapping' came from visualisation of these data grids in a 2d or 3d format where they form a similar shape to that of a topographical map.

When one says 'I'm mapping the engine' it is slang for simply tuning it. I don't expect they'd use this kind of language down at Maranello :)

Not tuning - adjusting already present sources to specific track, driver or weather. It is similar to chip tuning on passenger cars but ECU of F1 is not being tuned from some factory default to give more HP, more torque or to decrease fuel consumption but simply adjusted to specific demands. Even more, driver can choose from several different types of engine mapping during the race simply turning the knob on the steering wheel (SC drive mapping, warm up lap mapping, overtake mapping, cooling lap mapping, save fuel mapping etc).

Before two way telemetry was banned team could modify ECU from the pits, send data via radio signal and all driver had to do was to press acknowledge button in order to make engine run differently. Nowadays different types of mapping are preprogrammed and can't be modified but only selected by driver.
