In about a month I will be back in Germany and able to get one from the Honda guy,not sure of the price,but they don't have look for knock sensor,not sure about the speed limiter,but it is higher than the JDM or USDM ones.Anyway if you still need it then,get back to me and I can pick it up,I think he said he wants like $250,but I can probably get it for less.
