Indeed. The fact that Dale was able to dance right on the level of the knock threshold gave illuminating results. Ideally, we'd have 4 knock sensors, 1/cylinder, so we knew exactly where the knock occurs first. This is probably impractical and expensive. His results, however, strongly suggest that Dale's results were solely a function of unequal distribution between cylinders that was remedied by nozzle location. He controlled his variables very well. He was spraying the same amount of WMI, for instance, and had almost identical ambient conditions.
It is for this reason that I believe it'll be a non-issue with the EB manifold. Flow imbalances won't need addressed via different nozzle location. Additionally, the EB manifold will likely positively address the notorious cylinder #3 issues we experience. Our disproportionately high problems with that cylinder are likely for the same reason, I think.
