Title: Multi-Spark mentioned in help documentation, but missing from dialog menu?
Post by: WkndCalibrator on November 12, 2018, 03:35:31 pm

Hi Everyone,

Please bear with me as I am new to VEMS, but I noticed that Multi-spark is a feature mentioned in the documentation for the V3 ECU, however it doesn't appear in the configuration options. I'm wondering what I need to do to open up this as an option?

I know for start-ability (and to pass emissions), all major OEM's use some form of this at low RPM. It can help with cold starts and to ensure combustion despite varying fuel quality and vaporization on a cold engine...For those running E85 I feel like this would be rather useful

Thanks for any help,

I don't recall what firmware version introduced that, but I'm using 1.2.38 mostly these days and the setting is there under Ignition Settings.

Also the details are in the F1 help

Multi Spark
This enables multispark and will deliver multiple sparks per ignition output when the engine rpm is below 1500rpm (over a 25 degree windows from first spark position); The amount of deliverable sparks are calculated by these boundaries according to commanded dwell and separation time
