How exactly do these work? Noticed the deadbands can be set to a minimum of 32 degrees. So if ECT Part Throttle Red is set at 212, Hot Spark Ref is 203deg, and Cold Spark Ref is 158deg - and the Hot Spark and Cold Spark tables are -4 and +4 degrees respectively... what would timing be doing at 158, 203, 212, 240 degrees???
