My ECU is from a JDM Honda Stream, not sure if that matters. It coasted perfectly fine with the automatic transmission. But now that I have a 5 speed, it's not happy when coasting. I'm thinking the ECU either doesn't know that it's supposed to be controlling the idle since it doesn't know that it's in neutral or the ECU can't bring the idle down far enough now that it doesn't have the load of the transmission's pump on it anymore. If I turn the AC on while coasting the extra load stops the engine from surging, but it still idles quite high at around 1800-2K RPM until I come to a stop. As soon as I completely stop, the idle returns to normal.
