instead of an engine managment system designed to keep the cat alive (us version) its got an engine managment system to create maximum volumetric efficiency.
no secondary air pump, no egr valves, no varing band o2 sensors, mixutre is constantly stoich, instead of fluxuating to keep the cat alive.
no cats obviously. its a whole nother beast.
in a nutshell
us version- keeps the tree huggers happy
euro version- keeps its balls.
HaHa, that's just too funny...
You mentioned the 98octane number. Last time I was in europe, the readings were in the similar range. It was explained to me that that was on a different scale called Ron? I don't recall exaclty, but just that the ratings in Europe were higher than here but were still in the same range. Of course I could be wrong.
