Send that info my way, I have Diacom v2.85 but I don't think it matters what version it is.
I've been running 93 or 89 and haven't noticed any difference with my engine, either way I usually get like 15 counts on knock after a half hour of hard driving. If from what I've read, this is normal because the knock sensor isn't a perfect sensor. Grumpy, when does the ecm (746 or 747) start to retard the timing? Does the ecm look at the knock over a period of time like the TPS? I would hope it does but I'm not sure.
