Hello all,
I just finished up my B20B4 block with 99 Si head. The engine runs so smoothly, but I have not put on the P28 I have (still using the PR4) and I haven't been able to find anything about how to wire up the VTEC Solonoid, and I don't know if I need a knock sensor? P28 = ODB1? I have searched, but not been sucessfull

Anyone?
Thanks for any help, or direction!

 

You will not need a knock with a P28. And there are a bazillion threads on how to wire it up, if you search.

 

Thank you for the info!

 

i just finished up my lsvtec... i havent gone p28 yet so i just covered the knock sensor and ziptide it to the wiring harness

 

so you guys are saying that the p28's dont have knock sensors?

 

Yes P28 has no knock sensor. Why are you running a PR4 with a B20/Vtec? PR4 has no VTEC

 

PR4 was what I had in before the swap, and I thought I needed a knock, so I didn't put the P28 in yet. I wanted to verify that the car ran after I hooked everything up before throwing in the P28. I will put it in next time I drive the car (when the snow goes away) Also, I have not hooked up the VTEC wire, I need to find info on that.

Thanks again for all the help!
