I don't think the entire engine management system draws much at all, but I don't know any exact numbers. Hilborns setup utilizes batch firing, which would be just fine, except I would really like sequential, just because. (yep, just weird that way) I have been looking into AEM systems, and there is a fella in arizona that does conversions too, but his are an extra $1,000. But this is good stuff, I'll check into it. And thanks for all the suggestions.
