Adaptronic Ecu - http://www.adaptronic.com.au/product/esel015/ Currently has the z32 map and harness plug, however the Z32 market isnt huge so I have spoken to Adaptronic who will change it to any nissan base map and plug for a small fee which I will cover depending on what sort of car you have. $1200 Lots of features as seen below. This is plug and play so no stuffing around with install costs.
Features:
Built in 4-bar MAP sensor to replace the factory airflow meter.
VE tuning to simplify injector upgrades and simplify staging
Easy to use software
Plugs into factory wiring
Compatible with many third party dashes and devices
Full closed loop operation
Flex fuel capable
Launch control, antilag, flat shift and boost by gear all standard
Semi sequential injection and wasted spark ignition
Spare 0-5V analogue input
On the GTR / R32, VVT output can be reassigned to a different function
One additional spare aux output
3 spare digital inputs
Spare temperature input
Compatible with single and multi throttle body (for GTiR) tuning modes
SPECIAL FEATURES
This ECU also supports all the functions of the 440 ECU, however for advanced functions such as traction control, additional wiring and/or sensors will be necessary:
Flex fuel function – fill it up with gas/petrol or any ethanol concentration
Adaptive fuel control (self tuning) – reduces dyno time
Traction control function
Serial input for wideband O2 sensors (we recommend the MTXL)
Serial output for communication with dashes and dataloggers (we recommend the Race Technology units)
Headphone port for listening to the knock sensor while tuning
Basic closed loop ignition control
Closed loop fuel, idle, boost, 2 x variable valve timing control
Easy to use software
Dual maps (both maps required for GTiR for combined TPS / MAP tuning)
