Do B20s have a knock sensor? If no how did you wire this up for B20vtec?
tryed a search but found nothing.

 

run a seperate wire from the knock sensor to your inside harness where the ecu plugs into.. it should go to pin number d3

 

i think he means where does he put the knock sensor.
i always use one of the alternator bracket bolts, you will need to retap accordingly.

 

yea you would need to retap it.. my friends b20z2 came with a knock sensor could be cuz its a 2000 block

 

Got some info off hybridhonda, it said knock sensor don't need to be hooked up just has to be grounded? dis right? I already have a engine harness w/ a knock sensor hooked up to a B18c, w/ 95 P72 ECU, bout to put in the B20 block,just need to know where to plug in, also no PCV box on the back of B20's?

 

Or you could use an engine management system that allows the knock sensor to be disabled.

 

You could run a chipped ecu with the knock sensor disabled so you don't have to wire it. Considering the factory knock sensor is crap, that is what I would recommend.

How far in did you tap? Does it have to be completely through? Or just enough to screw in the knock sensor?

 

Why shouldn't use a knock sensor?, I think it's very important to prevent a premature sleeve cracking, am I right?

 

alright im haveing problems... my b20 vtec needs a knock sensor.. does it have to go all the way into the block or just deep enough to fit the sensor in?
