Fig 1 - MaxxECU Plugin kit consist of the following parts:
1. MaxxECU CMC connector
2. Vehicle harness adapter.
3. 16-pin extra connector.
4. 3-pin connector for extra 0-5v sensor (ex. pressure sensor).
5. 2-pin connector for external intake temperature sensor (IAT). Sensor not included!
ECU installation
Stock Engine Control Unit (ECU) on this vehicle is mounted on passenger side floor, behind the plastic guard.
• Remove the black large plastic guard, where the ECU is located.
• Disconnect the stock ECU from vehicle harness connector.
• Install MaxxECU harness into vehicle harness connector. Be sure to tighten connectors!
• Install included MAP-sensor into engine manifold with included hose kit.
• Vehicle is not equipped with an intake temperature sensor. Optional external sensor and cable is recommended.

Plugin Trigger
Nissan uses a particular trigger sensor, called CAS, mounted on the front of one pulley. CAS sensor is similar in many Nissan
models, but different cars uses different ”Sync window size”.
Nissan GT-R R34 ”sync window size” is 24.
Sometimes the CAS system generates strange trigger pulses which gives Trigger-Errors at start-up or low speed, this can
usually be remedied by changing ”Trigger polarity”.
Since the CAS is mounted on the camshaft, instead of crank (where it should be mounted) a precise ignition spark angle can
not be guaranteed because of the flexibility in the system. Over 500WHP, go for a crank trigger kit.
Be sure to check the ignition timing with a timing light, to ensure a correct ignition angle. READ chapter 5 in Handbook!
Notes
MaxxECU has some built in output test and diagnostics, see Diagnostics ---> Output test to test certain outputs.
