I'm wondering if I HAVE to do a 4 wire o2 conversion? I have my five wire 02 sensor from my 93 engine, and I just used it, but I was wondering if it will not be sending a correct signal, or when running the Y8 on the P28 ecu do I even need to do this, or is this just for everyone else who isn't fortunate enough to have the right 02 sensor sitting right there? lol!

Also, wtf is the deal with the VTEC pressure switch exactly?......

I got this Y8 in my car, running driving, but it isn't perfect. I'm trying to get it All good with no CEL or anything, and I don't think it is hitting VTEC atm........

Oh, and sorry for double posting I'm really tired, only just finished this swap about 4 or 5 hours ago and I'm REALLY tired...my bad lol! been at this swap 4-5 days now and I've been putting in like 7-10 hours a day >.>

 

What CEL's is it throwing? What are you asking about the pressure switch exactly?

 

I got code 7 and 10....I need to sort those out somehow, I got the 02 sensor, and the coolant system all good >.>
