Just a short note on this subject:

As ecu manufacturer, we considered and tested the spark ignition some years ago to be included in the ecus. Ignition was OK, but the possibility that the high voltage could damage the electronic components in the ecu (happened during tests), forced us to reject the idea. For those who need a reliable glow plug ignition, we can offer a ceramic glow plug, very similar to the ones used in kerostart, but with a thinner element and less power. Compatible with ecus from software version 5.54 and up.
