Extra inputs.MaxxECU Nissan Plugin has extra flexible inputs.AIN 1, temp sensor or switches.AIN 2, temp sensor or switches.AIN 3, 0-5V input.AIN 4, 0-5V input. Extra 3-pin connector (4).Normal state of GPO 7 is output, but can be configured as digital input!
Extra outputs.MaxxECU Nissan Plugin offers extra output for flexible control like boost control, fan control.GPO 7, GPO 8, INJ 8 (GND switched outputs).

Plugin TriggerNissan 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 S14a / S15 SR20 uses ”sync window size” to be 16. 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!
NotesMaxxECU has some built in output test and diagnostics, see Diagnostics ---> Output test to test certain outputs.
