h22a4 swap

i bought my bro's eg with a D16z6 swap in it. check engine light is on maybe due to none V-tec ECU p06 and also v-tec hasn't been tap. finished tapping my v-tec yesterday and using my chip P28 ecu and its throwing me 2 codes. one is code 21 and other is code 17. im pretty sure i read it right.
also while my bro was doing the swap they put a 96 sohc intake manifold on the engine and i was wondering if it would make a different if i switch it back to a 92-95 intake manifold?
