Are you refering to the Link ecu? If so I can confirm it is not. It states it comes with a MAP sensor IF the car does not have one from factory.
The below is taken straight out of the instruction manual
Nissan Skyline R34 GTS
The Link G4 Nissan R34 Plug-In ECU supports several options for fitting of a MAP sensor. Any one of the
following options can be used:
1. Factory MAP Sensor – The RB25DET factory MAP sensor is suitable for use. It must be re-plumbed to a
pressure source that measures vacuum and boost pressure*. The factory MAP sensor is wired to An Volt
3. The factory sensor is good for 125kPa (18psi) of boost.
2. MAP Sensor Wired Through AFM – To avoid running additional wires into the engine bay, a MAP signal
can be brought in through the AFM signal wires. The AFM is wired to An Volt 1. Refer to factory wiring
manuals for AFM wiring connections. Make sure the AFM can not be reconnected.
3. MAP Via Expansion Connector - The expansion connector provides power, ground, and analogue channels
for the connection of a MAP sensor
