Ignition system type
Specifies type of ignition system to use.
•Distributor - Only one output is used and can be used without HOME/CAM sensor mounted. Output drives all cylinders.
•Dual distributor - Requires a trigger system with a HOME/CAM sensor mounted. Output 1 drives cylinder 1. Alternating between firing output 1 and 2 independent of the configured firing order.
•Wasted spark - Ignites two coils at the same time. Can be used without HOME/CAM sensor. Can also be used with individual coils.
•Coil on plug(sequential) - Ignites every coil separately and requires a HOME/CAM sensor to be fitted.
•Coil on plug(sequential), 2-stroke/wankel - Ignites every coil separately and. Puts a spark every revolutions.
•Manual ignition distribution - Advanced way of controlling the ignition outputs. Do not use if you don't know what you are doing.
Ignition system delay
Specifies the actual delay that occurs when MaxxECU sends a spark signal and the actual spark is fired.
Note: How to adjust, lock ignition angle to a known value (like 10 deg BTDC) using the lock ignition angle feature below, give engine some RPM, if ignition "travels away" a few degrees use this setting to adjust the delay,to really make sure ignition are synced, even on higher rpm.
Lock ignition angle
Check the checkbox to lock the ignition advance timing at a given value, regardless of engine load.
Note: all other ignition timing (even cranking angles and/or other corrections) will be discharged when this feature is enabled, use with caution.
Ignition lock angle
The given value to lock ignition to. Locks all ignition timing to the given value.
Note: This setting is also available in Inputs --> Triggers/Home inputs, Trigger angle options.
Cranking ignition angle
Specifies whether to use a fixed value or a table for the cranking ignition advance.
Ignition timing during cranking, Configuration --> Engine settings, Engine max crank RPM. Can be done in table or fixed values.
•Time - Used by most coils.
•Duty % - Is needed by some old CDI systems.
Specifies the amount of time (in ms) the coil(s) is needed to be fully charged at 14V.
Min discharge time
Specifies the shortest time to be used to discharge the coil.
At high RPM and use of distributor(s), time between sparks can be too short and sometimes there is a need to shorten the charging time to make the coil rest enough between sparks.
Note: Generally, values less than 0.5ms should not be used as this increases the chance of spark overlap and misfires.
Specifies the duty of the ignition signal, percent of the signal to be "high".
Do not use for inductive coils/modules.
Inverted ignition outputs should only be used with some CDI-systems.
Note: Inductive ignition system will be damaged if inverted outputs is selected.
Dwell voltage adjustment
Specifies dwell compensation based on the voltage. In percent of the normal value.
Dwell MAP adjustment
Specifies dwell compensation based on MAP value. In percent of the normal value.
Note: Used where we need to "boost" the coils on high loads, use with caution.
Output entry method
Output number - The output is simply the logical number of the output (as printed on the wire).
Outputs as bit fields - Bit field - Outputs are entered as bit field, so that several outputs can be triggered from ONE event.
Add the values for the outputs you want to trigger:
Ign1 = 1
Ign2 = 2
Ign3 = 4
Ign4 = 8
Ign5 = 16
Ign6 = 32
Ign7 = 64
Ign8 = 128
Ign9 = 256
Ign10 = 512
Ign11 = 1024
Ign12 = 2048
To trigger output 3 and 6, add the values for the outputs and enter the result 4+32 = 36
Max dwell angle
The maximum angle (time) that can be used to charge the coils.
Depends on ignition coil setup, cylinder count and oddfire split angle.
For example a 4 cylinder engine with a single coil and distributor can use 720/4 = 180 degrees.
An 90 degree V6 (odd fire) with a single coil and distributor 720/6 = 120 - 30 degrees split = 90 degrees.
Sequential coil on plug setups = 720 degrees.
Event output number
Event number is in the logical order 1-2-3-4-nnn and is not affected by the entered firing order.
The outputs entered needs to be adjusted for firing order.
