I'm running 87 fuel, it's difficult to answer with a definitive yes or no at the moment, it seems that there is actually less detonation than there was before with the p07-a00, but then again could it be coincidence with the summer blend of fuel coming in? Seems like a few weeks ago my civic and both odysseys were detonating terribly and now not as bad despite the warmer temps.

It is worth noting as probably has been before, these Euro ecu's DO NOT require any EGR components, whether or not that plays a significant influence on on detonation is one's guess, but a malfunctioning valve/sensor on the US ecu will result in terrible detonation.
