Because you can't log with a wideband O2 sensor with the standard HPT box. you can how ever with EFILives V1 cable. As long as your not looking to tune anything newer then 07, then it would suite you fine. ($550) You can download EFILive's software from Download Software and play around with it. It will be in demo mode till you register it. PM me if you have any questions about it.
