Working on describing the fuel system and all it's entanglements in a document with flow charts and graphics, look out for a major update within the month.Here is a little teaser: The NSX's fuel injection timing isn't calculated based on the start or end time of of the injection. The ECU times the injectors (in 30* increments) so that the middle of the pulsewidth (minus deadtime and the time for fuel to flow from the tip of the injector to the valve) occurs as close as possible to maximum valve lift at operating temperature. At cold coolant temps, it injects fuel onto a closed intake valve to improve atomization. All of these variables will be adjustable within the definition.-Matt
