I recently did a swap into my 96 hatch. I got a b61a1 with a b18b tranny and a p72 ecu from a gsr in it. Car runs ok, but the vtec seems to be kicking in around 4500 rpms rather than 5500 rpms. Has anyone had this problem ever or is it even a problem with the engine or one of the components? Would putting in a vtec controller fix the problem? Any help is greatly appreciated
