Too bad we can't monitor KR per cylinder (as far as I know), or it might be more useful. More fuel could possibly be added to the middle (hotter) cylinders to reduce knock if those cylinders are prone to it. I know that the newer 5.0 mustangs often have heat/detonation issues with cylinder #8, which tuners sometimes compensate for by adding more fuel to that particular cylinder. Probably not much to gain on our platform, but hey, enthusiast problems.
