Ok here we go, got a ls/vtec with b16 head, had s300 that i was barrowing and had to give it back, so got avirgin p28, car still not running right, got cel did not have time to check it, do i need to chip it or add a knock, need help on this.. thanks

 

What else is done to the motor?
What does not running right mean?
Sounds like you need to check the CEL first, check it then get back to us and let us know what it is.

 

yeah im sure it is the knock, its stock las/vtec with b16 head b18a1 bottom end, dc headers evo 2 exhaust and gsr cams instead of b16a cams..i think it is the knock, 23 cel

 

Well a stock p28 isn't gonna throw a code for knock sensor cuz the d16z6 motor that it goes to doesn't have one. its prob something else but i cant really help you. But either way you are gonna have to chip the ecu cuz the stock map is gonna run lean since its for a 1.6 sohc motor and the timing maps are gonna be way off too... Plus a stock p28 is only gonna let you rev to 7200... Id just have it chipped and tune it on crome.
