See trigger problems for an explaination of polarity, arming voltage and so on.


Trigger/HOME input


trig sensor type

Specifies input type of the sensor.


trigger polarity

Specifies whether to trigger on rising or falling edge of signal.


arming voltage

The voltage of the signal to actually trigger on. Only available on VR signals.

Manual table - Manually enter the trigger arm voltages in the table.

Automatic tracking - Automatic trigger arm tracking


trigger pullup resistor

Whether to use the internal pullup resistor or not. Only available on digital inputs.



trigger decoder


Trigger system

See, trigger systems for a list of available trigger systems.


Home signal

See, trigger systems for a list of available home trigger systems.


Cam signal position

Specifies whether CAM signal is received before or after TDC.


teeth count

Specifies number of teeth on crankshaft trigger wheel INCLUDING missing teeth's.


missing teeth

Specifies number of missing teeth's on trigger wheel.


Sync window size

Specifies length of the longest hole in the CAS trigger wheel. Only visible with Nissan CAS trigger.



advanced trigger options


Note: Only visible when a missing tooth trigger system i selected.


Advanced trigger options

Enable/disable the advanced trigger options. Only activate if you have trigger problems during crank and know what you are doing.


Trigger time tolerance

Adaptive cranking tolerances

Extra tolerance at low RPM

1.5 missing tooth (Renault Megane 3 RS)


Missing tooth tolerance

Is the required lenght of the current signal compared to the largest difference over the last two engine revolutions.

Note: 80% is a good starting point for an average looking trigger signal. The adaptive system is only used BELOW ENGINE Max cranking RPM in your engine settings.




trigger angle


First tooth angle

The actual sensor position from engine TDC.


Lock ignition

Enable this to lock ignition to zero and disable fuel. Used in combination with a timing light to make sure timing is correct.


Note: When engine is started, there is an ignition lock function which can be used to lock ignition at certain ignition advance regardless of engine RPM.


Disable fuel and ignition

Turns off the ignition, fuel, and fuel pump (s).

Used for testings without starting the engine.

Note: When this function is active, it completely disables fuel and ignition outputs, even the Diagnostics --> Output test features.



Supported trigger systems

MaxxECU supports VR and digital sensor (hall-effect, opto) on crank and/or cam.
