Application Notes
• This Nissan Skyline R34 GT-T Nexus Plug 'N' Play
adapter harness is compatible exclusively with a
Nexus S3 ECU.
• Ensure that the correct basemap is uploaded into
the ECU before powering the unit through the Plug
'N' Play adapter harness.
• Please note that the basemap serves as a
starting point only, and the ECU will require
appropriate tuning. Haltech will not be held
resposible for engine damage due to the improper
use of basemaps.
• ATTESA - Nissan Skyline R34 GT-T vehicles
equipped with Nissan's ATTESA AWD system use
a control unit that requires a TPS signal to operate
correctly. This adapter harness supports this
feature and is equipped with a TPS output circuit
controlled by a Generic Duty Cycle table directly
connected via DPO2. This table is preconfigured
in all GT-T basemaps and is found in the NSP
Software's Navigation Tree under "Generics > 4WD
Out (Generic Output 1)". To ensure the correct
operation of your AWD system, please ensure this
table is enabled.
• Traction Control (TCS) - The factory traction
control system is currently not supported. The TCS
warning lights on the dash will illuminate.
