Any reason why mafcomp is ok if no downshift but i go rich when it does?Which makes perfect sense. Knock increases with engine load (or timing advance), and unless you are cruising at a nice even speed on perfectly flat ground (and not counting launches, passes, etc)...overdrive puts the most load on the engine, especially when it first shifts into it.
Once you get everything ironed out, you should be able to get rid of that OD knock with a little tuning
