Hi there, I own a JDM d15 with dual Vtec solenoids. When i bought that car it had an CVT trans which i replaced with an MT 5 speed. After that swap it feels like one of those Vtec wasnt working. So i changed the AT ecu ( p2j-00 ) and replaced it with an MT ecu ( p2j-003). As i plugged the MT ecu i caught an heck engine sign which was code 14 (IACV error). Is there any thing else you need to do than plugging the ecu ??? Im sorry if my english isnt perfect. I speak Dutch.
