I cant seem to find the answer im looking for. I have an EK and was looking to buy a JDM SOHC ZC OBDII. Does anyone know if the ZC engine has all the sensors that the d16y7 has? Thanks.

I could be wrong but I dont think they make an OBDII ZC. They have an OBDI ZC and a OBD0 Dohz ZC and SOHC ZC. They are a couple differences in the y7 and ZC.

They do, its basically a D16Y7 with D16Y8 intake and exhaust manifolds.

So it has all the required sensor that the OBDII system needs in order to fully replace the d16y7, right?

Mostly, it will be missing the CKF sensor, simply perform the CKF trick shown here ---> http://technet.ff-squad.com/ckftrick.htm

Thanks a lot guys. One last question, if I wanted to go back to USDM, will this method affect anything? Also, the method is telling me to completely cut C1 and C11 from the ecu connector, correct? Therefore, all we're doing is cutting C1 and connecting it to C4. Then cutting C11 and connecting it to C14?

No, everything will be the same as before, provided you undo the CKF trick (actually you could just leave it alone and just not bother plugging in the CFK sensor on the USDM engine)

Basically yes, you can simply depin C1 and C11 and then tape them off in case you wanted to undo what you did later either without having to splice.

You've been a great help 94EG8, so what your saying is C1 and C11 doesn't need to be wired to the other specified wires. Simply having no connection to those two wires will get rid of the problem. Sorry if you already answered this question, but I just needed to clarify that. Thanks again 94EG8 and all.
