OK...thanks alot!

Another quick question...Since he has a japanese b18c, would he have a knock sensor? only if someone else installed one right?

How could I get around that? Now even if I get the p72, it wont be getting a signal from the knock sensor? Should I get a jspec p72? Chip the usdm p72 so it wont need one, or I guess the logical thing to do is to install a knock sensor and wire it to the ecu, right?

Once again...Thanks for all the help!
