Ive gathered enough info to be able to create a Nissan PnP? version.

Trigger disc change is still required.

Completely PNP + replace the CAS with a swapped disc one.

+ Wideband sensor connection to the ecu

+ Air temp connection to the ecu

+ Boost control solenoid control

+ EGT sensor input

+ SD card logging ability

+ All features of the VEMS ecu.

Im going to be finding suitable connectors to connect the accessories into the ecu.
