ok the guy i bought it from says it has a b17 ecu in it. idk why he put that in there. but vtec isnt popping where its supposed to , i dont even know if its popping at all since i dont wanna rev that high and take the engine out of balance. if i get the right ecu for a b16 will it engage back at factory setting. and my gauge cluster is goin crazy readin al kinds of wack speeds it will be at 80 mph when im cruisin in 2nd gear. do i just need a gauge cluster, or the ecu or both

plz help me out
