Andy's little line had zero, nada, nothing to do with it.
And this ties in nicely with what I'm trying to say now about opening the ECU rule up to allow a level field. You already did it with the first step of the ECU rule. Since some boxes has vacuum lines, some didn't, the rule was changed to allow MAP sensors so that it wouldn't be a grey area and folks would be on a level field.

That needs to happen with cam position sensors, crank sensors, and distributors. Some ECU/engine management systems have an advantage because they come with certain factory components. We need to negate that advantage so all ECU cars will be equal.
