i have a 99 civic. d16y7 block and d16y8 head. do i need a knock sensor?

 

When using a p2p ecu, yes you do need one.

 

i dont know crap about knock sensors... where on the motor is it located, or if i have to put it in, where does it go?
with the p2t and p2p ecu in could not having a knock sensor make the car bog, and have really low idle. also when i gas it it doesnt catch. but when i plug my p2e non vtec ecu in its fine...
also what kind of knock sensor do i need?
and from what cars do i get them from?
thanks

The knock sensor is making you car go into limp mode which causes all your problems you explained. It looks like a large bolt, with a plug on one end and the other end has threads to screw into your block. On the y7 block look right under the intake manifold and there is a unused threaded hole. That is where the knock sensor goes. You can use a knock sensor from and obd2 block such as the d16y8 and b16a2.

 

you are the man...!
i finally got the answer i was looking for. right on.shoot, you are the same guy that helped me with my whole mini swap.
oh yeah since your online, i got another question.
how come when i plug my p2e non vtec ecu in, car runs fine?
just those damn vtec ecus are a pain in the ***.
which one would you recommend i use...
the p2p from a 99 civic ex or
a p2t from a 2000 civic si?
thanks again.
oh, you know a place that sells knock sensors? and please dont say junkyards...LOL
